Having been in this business for over a decade, I have supplied insulation materials to customers in Europe and the Middle East, but I have also fallen into countless traps. The most frustrating one was the XPS insulation board - it was all very impressive, but when delivered to the construction site, it either lacked strength or had falsely marked thermal conductivity. Last year, I received a contract from a German client who required a thermal resistance value of R-10 or above. I sent samples of a well-known brand for testing and all passed. However, when the bulk goods arrived at the port for testing, the result was only R-7.5. In the end, I had to pay the freight and replenish the goods. The client directly kicked me off the supplier list. Who wouldn't be furious about this?  Later, I summarized that the main problems in the industry were three: Firstly, there was false performance labeling. The manufacturers used laboratory data to deceive customers. Secondly, the dimensional stability was poor. The XPS boards delivered to the Middle East contracted and deformed, and the decorative lines simply didn't match the seams. Thirdly, the supply cycle was unpredictable. During peak seasons, the production schedule was set for two months, and the construction sites were constantly pressured to complete the work on time. The customers were even more frustrated - they were engaged in Interior Decorative Wall Panel Products, and the wall decoration needed to be constructed together with the insulation layer. If the board deformed, the EPS Decorative Moldings would crack, and the entire wall would have to be scraped off and rebuilt. The owner of the decoration company complained to me, saying that using your company's boards, they had to redo the work three times, and the workers' wages were even higher than the cost of the materials.  So now I'm really focusing on LONGER. Their XPS insulation board is truly capable of being used for low-temperature cold storage facilities - with a closed-cell rate of over 98%, moisture can't penetrate. We supplied a batch to a Norwegian client, which was used on the exterior wall of a cold storage at minus 20 degrees Celsius. For three years, not a single bulge has appeared. Moreover, the compression shear strength reaches 0.12 MPa, which is 30% higher than the national standard. Even if you kick it with your foot, it won't break. What's more crucial is that they combine this with EPS Insulation Board to make composite decorative panels. The surface is directly hot-pressed with an engineered wood board, saving the construction team three processes - laying a base layer, hanging mesh, and plastering. The construction period is reduced by half. An engineering contractor in Dubai calculated that using LONGER's XPS board for the exterior walls of a villa results in a combined cost that is 40% lower than using ordinary extruded polystyrene board combined with stone dry hanging, and it also provides an additional layer of insulation.  In the end, the value of XPS insulation board lies in two aspects: it helps save energy and provides insulation in summer, and prevents moisture and prevents mold in winter. It is the most cost-effective for use in basement of villas, exterior walls of cold storage facilities, and steel structure roofs. When combined with their EPS Decorative Moldings (Roman column heads, window casing lines), it achieves a seamless integration of insulation and decoration, eliminating the labor cost of a separate construction process. Here are a few tips and product features:   Product Features  Low density but high compressive strength (35kg/m³ can achieve 0.15MPa), with a transportation damage rate of less than 0.2%. Flame-retardant B1 grade, self-extinguishing when away from fire, with a smoke density 60% lower than that of the same grade. Successfully passed the fire safety inspection in the Middle East on the first attempt. Purchase Tips  Don't just rely on the thermal conductivity. Ask the manufacturer to provide the measured value of the "water vapor permeability coefficient" - a value lower than 2 ng/Pa·m·s indicates true waterproofing. When shipping the entire cabinet by sea, have LONGER perform "tray vacuum coating" to ensure the humidity upon arrival at the port does not exceed 5%. Otherwise, the boards will absorb moisture at the construction site and then dry out, resulting in a shrinkage rate of up to 2%. Currently, all my Italian and Saudi clients have switched to LONGER. The return order rate is 100%. To put it simply, when dealing with overseas B2B wholesale, less is more - having a reliable XPS board supplier can save you 80% of customer complaints. Don't ask me how I know - I learned from the losses.

      I've been in the procurement business for over a decade. To be honest, I've encountered many problems with insulation materials. At the beginning, I was greedy for cheap prices and bought a batch of ordinary boards. However, when they were installed in a chemical plant project, problems emerged within half a year - they absorbed water and bulged. The insulation layer looked very wet, and the client complained all at once. Later, I also encountered a problem with the fire resistance test getting stuck. The party's inspection directly shook their head and said that it couldn't withstand the fire at all. During that period, just dealing with returns and compensation almost drove me into depression. In the end, the two things that really bothered me were: first, the waterproofing ability was poor. Over time, the insulation effect was directly reduced; second, the fire resistance grade was deceptive. Even with the "A grade" label, when tested, it turned out to be false.  Later, we switched to LONGER's rock wool board, and things finally stabilized. I mainly deal with overseas B-end wholesale, with customers distributed in Europe, America and Southeast Asia. The requirements are generally not low. We tried several brands, and the products of LONGER immediately showed a difference when used - uniform density, each block is compacted, and when cut, it doesn't break or become fluffy. The workers had less trouble cleaning up debris in the first month of installation. Of course, what I value most is its waterproofing property. When placed outdoors for a long time and exposed to so much rain, opening the package didn't absorb water. The water test was also satisfactory. There's no need to worry about fire resistance either. It has A1-level certification, which has been tested several times. The conclusion given by the laboratory was "non-combustible", without smoke or cracking. The factory took the report to the fire department for inspection and never encountered any problems.   By the way, the environmental aspect of LONGER is also quite interesting. Currently, overseas regions are conducting increasingly detailed checks on the source of materials. They have a recycling process where they incorporate the glass bottles, perfume bottles, penicillin bottles, and health product bottles that we commonly see into the raw materials, and then re-melt and stretch them to make fiber boards. This operation not only recycles the discarded bottles but also is cleaner and more durable than traditional slag fibers. When pitching a deal to foreigners, mentioning this point really works. They truly get it.  Product features, I have summarized them into three points:  Waterproof performance is excellent - hydrophobicity rate over 99%, and it retains insulation even when soaked and dried. Fireproof compliance is assured - A1 grade non-combustible, won't smoke even when heated to a certain temperature. Environmentally friendly materials - mixed with recycled glass bottles, perfume bottles, penicillin bottles, and health product bottles from waste, which can add points in the review report. As for experience, there are two points:  ① Ask the manufacturer to send samples. Take a spray bottle and spray it for a few seconds. See if the water droplets roll off. If they don't stick together, don't buy it. ② Don't just look at the thickness. The bulk density is more important. The 120kg/m³ boards from LONGER serve as the base, and their load-bearing effect is better than that of the 150kg boards from other brands.  Doing wholesale business is essentially about helping customers save time. The LONGER brand has a good reputation among overseas users. Over the years of our cooperation, we have rarely dealt with any after-sales issues. The quality of the materials ultimately determines whether customers will place repeat orders. To be honest with you: Those boards that keep breaking down frequently - no matter how much commission we earn, we don't feel at ease. Later, we changed to a better product, which was more reliable and made customers feel more secure.  

The core difference between XPS waterproof backboard and cement backboard   Comparison Dimension XPS Waterproof Backing Board Cement Waterproof Backing Board Waterproof & Moisture Resistance Closed-cell structure, 100% moisture-proof, no water absorption or expansion. It can maintain stable performance in humid environments for a long time without mold or rot. Requires additional waterproofing treatment. The cement material itself is prone to water absorption, which may lead to mold growth and structural damage over time if not properly treated. Weight & Installation Lightweight, easy to carry and cut. A single person can complete the installation operation, which greatly saves labor costs and shortens the construction period. Heavy and bulky, requiring multiple people to cooperate during transportation and installation. Cutting is difficult and requires professional tools, which increases the difficulty and cost of construction. Load-bearing & Durability High rigidity, strong compression and impact resistance, not easy to crack or deform. It has excellent weather resistance and can maintain stable performance in harsh environments such as high temperature, low temperature and humidity. Ultra-high load-bearing capacity, but brittle and easy to crack if subjected to impact during construction or use. It is also prone to aging and chalking when exposed to the outdoor environment for a long time. Construction Cost Higher efficiency in installation, lower labor costs, and no need for additional waterproofing materials, so the overall construction cost is more economical. Longer construction cycle, higher labor costs, and additional investment in waterproofing materials and processes, resulting in higher overall construction costs. Applicable Scenarios Suitable for all-scene waterproof projects, including wall cladding, flooring, roofing, bathrooms, basements and other indoor and outdoor construction scenarios. Only suitable for ultra-heavy load scenarios, such as industrial floors, outdoor high-load ground and other special construction projects that do not require frequent maintenance.         Why Moisture-Resistant XPS Backing Boards Are Suitable for Most Projects No Additional Waterproofing Required - Save Time and Money As a professional supplier of XPS waterproof backboards, Longer is well aware that for most construction projects, time and cost control are of paramount importance. Unlike cement backboards that require additional waterproof coatings and membrane applications, our moisture-proof XPS backboards, with their closed-cell extruded structure, inherently possess waterproof properties. From the moment of installation, they form a reliable waterproof barrier, eliminating the need for complex additional waterproofing procedures. This not only reduces the construction period by an average of 30% but also saves on waterproofing materials and labor costs, helping you maximize the project's benefits. Long-lasting, not moldy or rotten. One of the most troublesome problems in construction projects is the mold and rot of building materials caused by dampness, which not only affects the appearance of the project but also reduces the structural safety and service life. Our moisture-proof XPS backboard has completely solved this problem. Its closed-cell structure does not absorb water at all, and it is not easy to breed mold and bacteria even in long-term damp environments such as bathrooms and basements. After years of use, it can still maintain its original performance and appearance, eliminating the trouble and cost of later maintenance and replacement. This is an advantage that no matter how perfect the additional waterproof treatment of cement backboards is, it cannot compare with. When to choose cement backer board instead of XPS waterproof backer board? High-load-bearing scenarios, such as the floors of industrial plants Although our XPS waterproof backboard has excellent load-bearing capacity, it still cannot match the cement backboard in scenarios with extremely high load requirements. For instance, in industrial plants and warehouses where heavy equipment and large amounts of goods need to be supported, the cement backboard would be a more suitable choice. Its extremely high load-bearing capacity can meet the special demands of such projects and ensure the stability and safety of the ground structure. Extreme high-temperature environment In extremely high-temperature environments (such as areas near high-temperature equipment in industrial workshops), the high-temperature resistance of XPS waterproof backboards will be somewhat affected. In such cases, cement backboards with better high-temperature resistance are more suitable. They can maintain structural stability in high-temperature conditions and prevent deformation and damage caused by high temperatures. However, it should be noted that even when choosing cement backboards in such scenarios, additional waterproofing treatment must be done to prevent damage from moisture. Longer XPS waterproof backboard: The better choice for 90% of construction projects How does our XPS backboard solve the limitations of cement backboards? After years of research and development, Longer's XPS waterproof backboard has comprehensively addressed the pain points of cement backboards in practical applications. In response to the need for additional waterproofing of cement backboards, our XPS backboard, with its advanced extruded closed-cell technology, achieves 100% waterproof performance, eliminating the need for additional waterproofing measures. Regarding the heavy weight and difficult installation of cement backboards, our XPS backboard is lightweight and easy to cut, significantly improving construction efficiency and reducing labor costs. In addition, to address the issue of mold and rot in cement backboards, our XPS backboard is moisture-proof and mold-resistant, with a long service life and no need for frequent maintenance. Bulk wholesale solutions for large-scale replacement We understand that many construction companies and purchasers are seeking more economical and reliable alternatives to cement backboards for large-scale projects to replace traditional cement waterproof backboards.

  With over a decade in procurement, I've handled hundreds of construction materials. In recent years, EPS cement walls have gained popularity in overseas projects—but honestly, I’ve encountered many issues along the way. Colleagues often ask me right away:   Why do EPS wall panels at construction sites frequently develop cracked joints? Why do boards warp halfway through delivery? Why do quotes seem cheap, only to end up more expensive when factoring in waste and rework costs? The root causes are simple: substandard material density, uneven cement layer thickness, and poorly compacted EPS beads in the core. For clients, it’s even worse—project delays go without saying, and they also face complaints from project owners.    My solution at the time was simple: I directly approached Longer, a leading domestic manufacturer. Their approach to solving the problem was equally clear—focusing relentlessly on raw materials and manufacturing processes, replacing traditional manual casting with fully automated production lines. The result? In my Middle Eastern hotel project last year, we used Longer's EPS Cement Wall covering 5,000 square meters. Installers reported clean cuts and perfectly flat installation. Over a year later, not a single crack has appeared. Moreover, due to its lightweight nature, the structural load on the steel frame is significantly reduced. The client even sent an email specifically praising, "Finally, I don't have to keep running to the site to supervise repairs anymore."  Let's talk about product value. This EPS Cement Wall is primarily used for partition walls and insulated exterior walls, especially suitable for overseas steel-structured buildings. It reduces construction time by three times compared to traditional aerated blocks and allows direct nailing or hanging of heavy objects without the need for pre-installed studs. Several construction teams I've worked with long-term now exclusively specify Longer products because they've found that the boards have a low breakage rate during transportation—every bit saved translates into profit.    Speaking of this, let me briefly mention two other products in our portfolio: SPC Flooring and PVC Wall Panels. Many overseas B2B customers tend to purchase all three together—using PVC Wall Panels for waterproofing bathroom walls, installing SPC Flooring on the floor for durability, and employing EPS Cement Walls for insulation and soundproofing in partition walls. These three Longer products work well together, making warehouse handling convenient. I often tell new clients: if you want to save time and effort, just order all three in one container, and I can even label the unloading sequence for you.    Product Features:    High Crack Resistance: EPS granules are pre-expanded and compressed into shape with cement mortar in one step, resulting in minimal internal stress and no cracking throughout the entire panel.   Precise Dimensions: Length and width tolerances are controlled within 1mm, with on-site cutting waste below 2%, saving labor.   Fireproof Class A: The core layer is self-extinguishing EPS, covered by a 15mm thick cement surface layer that extinguishes automatically when removed from flame, passing British standard fire tests.     Tips: ① For bulk orders, always request manufacturers to arrange panels according to container dimensions. Longer provides free container layout diagrams, reducing shipping costs by over 10%. ② For overseas construction, pay attention to adhesive selection: ordinary white cement mixed with glue tends to peel off; we recommend using specialized two-component bonding mortar—Longer offers free formulation support.    Simply put, in procurement you need to spend money where it counts. Over the years, I've tried other brands, but when it comes to consistent quality control and after-sales support, Longer has never let me down. If you're stocking up for overseas construction sites, I recommend directly requesting their latest test reports and project references—this way you can avoid the hassle of factory inspections yourself.    

  When choosing wall panels for decoration, many people are confused: indoors, they worry about odors and moisture-induced mold; outdoors, they fear deformation from sun exposure and rot from rain. After much deliberation, either the appearance quality doesn't meet the standard or the durability is questionable. Especially for those who want to unify the indoor and outdoor styles, it's hard to find a suitable model. Until I discovered LONGER's wall panel wpc, it's truly a "all-rounder" in the decoration field!

The unified style indoors and outdoors is very effective, and the feedback from clients is very good. There have been no problems of deformation or mold." Mr. Wang, the homeowner: "Both the balcony and the background wall of my living room are made of this WPC wall cladding. The appearance is very high-quality. And after being exposed to wind, rain, and sun for over a year, it hasn't deformed at all. It's much better than I had feared!"  Mr. Li, the owner of the building materials store: "After selling building materials for so many years, LONGER's WPC exterior wall cladding has the most repeat customers. Whether for household use or for construction projects, customers all say it is durable and attractive. The reputation is truly solid!"    

  I have been engaged in building materials procurement for over a decade, and the product that causes me the most headache is XPS backer board. The industry's pain points are obvious: ordinary materials tend to mold and deform in humid environments. If the density of XPS bathroom backer board is uneven, it is prone to cracking. Moreover, the insulation performance of XPS thermal insulation board is often unstable. These problems have caused us wholesalers a lot of trouble - there are continuous complaints from overseas customers, high return rates, and often additional compensation for construction losses, leaving us with no profit left. However, since we started promoting the Longer XPS series, the situation has completely reversed. What we provide is a one-stop solution: from the base layer of the wall to the bathroom-specific solution, and then to the entire house insulation, covering all aspects. The actual effect is very obvious: customers report that after installation, the wall is flat and does not crack, the bathroom is free from mold stains again, the insulation performance has been measured to meet the standards, the project has passed the acceptance inspection for the first time, and our wholesale orders have become increasingly stable.  The core value of this product lies in making wholesale purchasing simple and reliable. In terms of application, XPS backer board is suitable for interior wall panels, XPS bathroom backer board is dedicated to wet areas, and XPS thermal insulation board is used for exterior wall insulation systems. For us as wholesalers, this means that with a stable and reliable product line, we can meet the diverse needs of customers, reduce inventory pressure, and enhance reputation.  Based on my experience of handling countless orders over the years, I have summarized several key features and practical suggestions for your reference, fellow professionals:  Product Features:  Moisture-proof and mold-resistant core: The XPS bathroom backing board from Longer incorporates a moisture-proof core layer, ensuring stable performance in humid environments and significantly reducing post-sale issues. High strength and stability: The XPS backing board has uniform density and excellent compressive strength. After installation, the wall is less likely to deform, providing a solid foundation for subsequent tile installation or decoration. Thermal insulation and energy conservation: The XPS thermal insulation board has a low and stable thermal conductivity, helping end customers effectively improve the energy efficiency of the building. Tips for procurement and use:  Batch inspection: When purchasing in large quantities, it is essential to conduct random checks on the density of the panels and the flatness of the edges. This is the first step to ensure the quality of the construction. Adaptation suggestion: When recommending to customers, clearly distinguish between ordinary areas and bathroom wet areas. Use corresponding panels for matching, which can effectively enhance the project value and our professionalism. Storage instructions: The panels should be stacked flat in a dry environment and avoid direct sunlight. With just one simple step, they can be kept in the best condition at the time of delivery. In summary, choosing Longer means choosing peace of mind. It is not just a product; it is also a quality endorsement from our wholesalers for expanding overseas markets. If you have specific project requirements for solutions? Feel free to discuss at any time.  

  Those who are engaged in the wholesale of building insulation understand that the most annoying thing is encountering these troublesome issues: the materials absorb water quickly, and once they get damp, they start to mold and deform, and the insulation effect drops sharply; the construction is also troublesome, consuming a lot of labor and time, with a high rate of later repairs, and the money spent doesn't yield good results, directly affecting project delivery and payment. To address these pain points, Longer specially customized an XPS backing plate for overseas B-end buyers. It is combined with XPS Extruded Polystyrene Board, XPS Tile Backing Board, and EPS Cement Wall for one-stop solution to all problems.

    Those who do exterior wall decoration know that there are many troubles: traditional lines are heavy and difficult to install, and they are prone to cracking and deformation after installation, which is costly and laborious to repair; Wall Tile is troublesome to install and is prone to hollowing and falling off; EPS Cement Wall is particularly cumbersome to construct and difficult to do well; XPS Extruded Polystyrene Board is also difficult to match and requires a lot of effort. These problems not only delay the construction period but also cost a lot of unnecessary money, and the later maintenance is also very troublesome. Longer has long understood these pain points and specially launched EPS lines, along with a complete set of solutions. Whether it is Wall Tile, EPS Cement Wall, or XPS Extruded Polystyrene Board, they can all be perfectly matched. It can not only make the exterior wall look good but also solve key problems such as insulation, anti-cracking, and sun resistance. Exterior wall decoration no longer requires much effort and can save a lot of money.   Product features of Longer EPS lines 1.

    Those involved in building tile installation know that there are two common problems: Firstly, the tile backing boards lack fire resistance, posing potential safety hazards, and have poor insulation, consuming excessive electricity and energy; Secondly, ordinary backing boards are prone to moisture absorption and do not stick firmly, causing tiles to become loose and fall off. Whether it's during construction or procurement, both parties have to redo the work and incur costs, and may also bear safety responsibilities. To address these issues, Longer has specially launched the Fireproof and Heat-Insulating XPS Ceramic Tile Backing Board, using extruded XPS waterproof backing board as the core material. It can provide fire resistance, insulation, and waterproofing, completely solving these problems. Whether it's for residential buildings, shopping malls, or public facilities, as long as the walls are tiled, it can be used. It perfectly fits all scenarios of XPS waterproof backing board for wall cladding, ensuring both construction safety compliance and reducing costs for later maintenance. It is practical and cost-effective. This backing board is made of high-quality extruded polystyrene material and undergoes special flame retardant treatment. Combined with specialized ceramic bonding technology, unlike traditional backing boards, it does not have the issue of either poor insulation or poor waterproofing. Its extruded XPS waterproof backing board has a closed-cell honeycomb structure, which can firmly block moisture and prevent the wall base from getting damp and moldy. It can also bond more firmly and fundamentally avoid tile loosening and falling off. Whether in damp areas like bathrooms and kitchens, or in complex environments like exterior walls, it can be used.  In addition, its fireproof and thermal insulation effects are also very practical. The fire resistance can reach the B1 level of flame retardancy, which can slow down the spread of fire and provide an additional layer of security for the building. The thermal insulation effect is also good, as it can reduce heat loss between indoor and outdoor areas, saving a lot of electricity costs and meeting the requirements of current green buildings.

Hello everyone, I'm the technical consultant of Longer. When chatting with suppliers and construction workers, people often ask: "Is there a special size of XPS backing board available?" "For outdoor terraces, can we get a more waterproof one?" In many project scenarios, standard boards simply don't work, and using them haphazardly will only cause trouble. Today, I'll open up and tell you the truth, when you need customization and how to customize in Longer. Whether it's for export, outdoor use, or basements, I'll explain everything clearly to you.   I.Don't force yourself to choose the standard board. Customization is much more convenient.  Not all tasks need to be customized. But in these cases, choosing standard boards would be a complete waste of time and money; customization is the right approach.  1.The size is special. Cutting the standard board causes pain.  For instance, when renovating old houses or decorating irregular spaces, the dimensions of the walls and floors are quite strange. The standard 4x8-foot boards are wasted after being cut in half, and they have to be pieced together repeatedly, resulting in extremely low construction efficiency. Some commercial projects have specific designs, requiring boards of specific lengths and widths. Customization can ensure a perfect fit, eliminating the need for unnecessary fuss.  2. In special situations, ordinary boards cannot withstand the pressure.  Like outdoor terraces, which are exposed to wind, sun, heat and cold alternations, ordinary boards won't last long before they deform; basement floors are damp and need to be insulated, and regular models simply can't handle it. At this point, custom-made solutions are necessary. The density and waterproofing level can be adjusted, perfectly fitting the scenario, and there's no need for rework later.  3. Export orders have their own specific rules  Exporting companies all know that the requirements for building materials vary from country to country. The EU demands environmental certification, while the US has specific requirements regarding measurement units. Standard boards often fail to meet these standards. Customized products can precisely match these requirements, and the packaging and labels can also be modified as needed. This way, the products can pass through customs smoothly without any issues.  II. In the case of Longer customization, all of these can be modified as per your requirements.  Many people think that customization just involves changing the size. But there's much more to it. From size to performance, from appearance to export compatibility, everything can be adjusted according to your needs.  1.Size and thickness: Make it as large as you want!  In terms of size, whether it's a large board that is larger than 4x8 feet or a small irregular board, as long as you provide a drawing, we can make it. The thickness can be flexible, ranging from 6mm to over 20mm. For example, if the basement requires a thicker insulation layer, 25mm or 30mm can be arranged. The load-bearing and insulation can be completed in one step.  2. Density performance: Enhanced for greater durability  For outdoor and industrial environments that require durability, a high-density option should be chosen; for indoor construction that aims for lightness, the density should be adjusted to a moderate level. Additional benefits can be added for waterproofing and insulation. Shower areas need high waterproofing, and areas in cold regions need strong insulation. These features can meet the requirements and are more suitable than standard panels.  3. Branding: Adhere to your own logo, which is more professional.  If we go for a private brand, we can print your logo and specifications on the board, making it look professional and enhancing the recognizability. We can also customize the packaging. For export, we can provide wooden packaging and moisture-proof packaging as required. We will handle all of this for you.  4. Export Compliance: Assist You in Adhering to Regulations in All Countries  To produce custom XPS tile backboards, we first need to understand the regulations of the target country. We will meet all the environmental protection and fire prevention standards. The unit labels and the language of the instructions will also be in accordance with the local requirements. We won't be rejected due to non-compliance.  III. Customization is just three steps away, simple and without hassle.  Don't think customizing is troublesome or that coordinating back and forth is tiring. Just three simple steps and you'll easily get the product you want.  Step 1: Clearly articulate the requirements, and the more detailed, the better.  Tell us clearly what it is for (outdoor, basement or exit), what the dimensions are (length, width, height), and what effect is needed (waterproofing, insulation). If you have the drawings, please send them directly. This will be more accurate. For example, if you say "An outdoor board for exporting to the United States, 3x6 feet, resistant to low temperatures", we can immediately come up with a solution.  Step 2: We will propose a plan and first produce samples for verification.  We have received your request. We will provide you with the solution within 1-2 working days, including parameters, quotations and delivery time. If you are not sure, we can first make a small sample for you to review. Once you are satisfied with the appearance and performance, we will proceed with mass production to avoid any problems with large-scale production.  Step 3: Confirm the order and wait for delivery.  The samples are fine. Once we sign the contract and you pay the deposit, we will start the production. During the production process, we will keep you informed of the progress in real time. If there are any issues, we can make changes at any time. Once the products are ready, whether it's domestic delivery or export customs declaration, we will handle everything for you throughout the process.  IV. Two real cases for your reference  Let me show you two custom orders we have done. See if any of them resemble your project.  Case 1: Outdoor Terrace Customization Edition  A client wanted to build a terrace for their villa. It needed to be resistant to both heat and cold, have strong waterproofing properties, and be of irregular dimensions. We made a 20mm thick high-density board for him, which enhanced the waterproofing performance. The size precisely matched the shape of the terrace. It has been used for over two years and has not deformed or leaked water. The client was extremely satisfied.  Case 2: Customized Products for Export to Europe  A foreign trade boss wanted to export to Europe and ensure compliance with the EU environmental standards. The packaging had to be in millimeter units and be moisture-proof. We adjusted the formula according to European regulations, determined the dimensions, and also prepared an English manual and certifications. The goods passed the customs inspection smoothly without any hitches.  V. Frequently Asked Questions, Helping You Avoid Pitfalls  How many units should be ordered for the customization?  There is no mandatory requirement. Both small batch samples and large quantity purchases can be accepted. The larger the quantity, the more cost-effective the unit price will be. Just communicate with the sales department for details.  2. How much longer does customization take compared to the standard board?  It usually takes 3 to 5 days, depending on the complexity. Just changing the size is quick; but if we need to optimize the performance and adapt to the export requirements, it will take a bit longer. We will clearly inform you of the delivery time in advance, so it won't affect your work.  3. Can custom-made items be returned?  Since it is a custom-made product, if the design you confirm doesn't match the original plan (such as different dimensions or performance), we will redo or adjust it for free. If you change your requirements yourself, we will also try our best to optimize it for you and minimize the losses.  Finally, let me say something truly honest.  Customizing XPS backing panels, the key lies in choosing the right manufacturer. Avoid those who only use templates; they are prone to problems later on. Longer has been in this business for over a decade. They are experienced in custom work for outdoor, basements, and export projects, and can accurately meet your needs.  If you have any customization ideas, whether it's regarding size, performance or export, feel free to talk to us. No empty promises here. Just follow your requirements and you'll save yourself a lot of trouble and get the suitable product.  

Hello everyone, I'm a technical advisor for Longer. I've been working with XPS tile backer boards for many years and have dealt with many construction workers from all over. I've noticed that many people choose good boards but fail to do a good job with the installation details, resulting in problems like hollowing, water seepage, and tile detachment later on. It's really a pity. Today, I'll use plain language to explain the installation steps for the ground and kitchen and bathroom walls, as well as the most common mistakes, based on the characteristics of Longer's XPS boards. It's all practical and no nonsense, so even novice workers can understand it at a glance.   I. Preparation before installation: Get all the tools and materials ready, and getting the base right is half the battle. Don't underestimate the preparation stage. Using the wrong tools or not properly treating the base will make all your efforts in vain later on. Let's keep it simple and avoid using complex professional terms. 1. Essential tools and materials: Don't make do with anything. The key point is: XPS boards have special adhesives. Don't use ordinary cement mortar! It won't stick well. This is the most basic mistake. Remember it first. Main board: Longer's 4x8-foot XPS tile backer board. Choose the thickness according to the project. 10mm is sufficient for home decoration and regular construction sites. Adhesive: Special adhesive for XPS tile backer boards, compatible with the boards, strong and won't damage the boards. Small tools: A board cutting knife, a tape measure, a level, a rubber hammer, waterproof sealant, and a utility knife are enough. No need for complex equipment. Fixing parts: Prepare some plastic expansion bolts for wall installation. For wet areas like shower zones, also prepare some stainless steel screws with waterproof washers for extra stability. 2. Base treatment: Just keep it flat and dry. No need to overdo it. Our XPS tile backer boards have low requirements for the base. They are much easier to handle than cement boards. Just follow these few simple requirements: Clean the ground or wall, remove any dust or oil stains, grind down any protrusions, and fill in any depressions with cement mortar to make it flat. Don't leave any bumps or holes. The base must be dry. Don't install it if it's still damp, especially in bathrooms. Do the basic waterproofing first and wait until it's completely dry before proceeding. Don't worry about the ground's load-bearing capacity. The ground in residential and ordinary commercial areas can usually meet the requirements. No additional reinforcement is needed. 3. Board cutting: Even beginners can do it. It's very simple. Longer's XPS boards are lightweight and rigid. Cutting them is a breeze. Just use a cutting knife to make a mark along the line and break it off. It's much easier than cutting cement boards. After cutting, smooth out the small burrs on the edges. Don't leave any rough edges. If you want a stronger bond, lightly brush a layer of special adhesive on the back of the board. This is a small trick that can significantly increase the bonding strength.   II. Ground installation: Three steps to complete - apply adhesive, lay the boards, and seal the joints. The ground is the most common installation area. The process is the simplest. Just remember to apply the adhesive evenly, lay the boards flat, and seal the joints tightly. That's basically it. Step 1: Apply the special adhesive. Don't skimp on the adhesive or apply it randomly. Use a notched trowel to apply the adhesive to the base. A thickness of 3-5mm is sufficient. Make the lines neat and even. Don't apply it in random patches. Also apply a circle of adhesive around the edges of the board's back. The width should be 5-8cm. This is like a "double-sided stick". This way, the boards won't hollow out after installation. Don't be lazy at this step. Step 2: Lay the 4x8-foot boards, stagger the joints and leave gaps. Place the boards with the adhesive evenly and use a rubber hammer to gently tap them to make them adhere to the base. Then use a level to check that they are not crooked. The flatness error should be controlled within 2mm. Key point: Lay the boards with staggered joints, just like laying tiles. Don't align the joints of adjacent boards. Leave a 2-3mm gap between the boards. Don't install them seamlessly. Leave some space for thermal expansion and contraction. Otherwise, the boards will bulge in hot weather. Step 3: Seal the joints, especially in kitchens and bathrooms. Don't miss any. Use waterproof sealant to seal the joints. Pay special attention to kitchens and bathrooms. Don't leave any unsealed joints. When the glue is completely cured, which takes about 24 hours, fill the gaps between the boards with waterproof sealant, making sure there are no air bubbles and no gaps. Also, make sure to seal the edges where the boards meet the walls and pipes. This is crucial for preventing water seepage. Don't think it's a hassle. Step 4: Once the sealant is dry, which takes about 12 hours, you can directly apply tiles. Tap the boards to check if they are not hollow or loose. Then, you can directly apply the tile adhesive and lay the tiles. The surface roughness of our XPS boards is just right, so no additional treatment is needed. The tiles will stick very firmly. III. Installation of Kitchen and Bathroom / Shower Area Walls: One More Step for Fixing, More Effective Waterproofing Wall installation has the issue of bearing weight, especially in the shower area where there is a lot of water and things to hang. Pay a little more attention to fixing and waterproofing, and it will be fine. 1. Slightly modify the method for different walls If it's a concrete wall, you can directly apply the glue and lay the boards as you would on the floor, which is convenient. If it's a light steel keel wall, first fill the space between the keels with some insulation cotton, then add a piece of plywood to the back of the board as a backing, and fix the board to the keel with plastic expansion bolts. The bolts should be spaced about 30 cm apart to ensure the board doesn't fall off. 2. Small details for wall installation, remember them to avoid mistakes Lay the boards from bottom to top, with staggered joints, just like on the floor. For walls over 2.4 meters high, add an extra keel in the middle for support to prevent the boards from sagging. For the shower area walls, after laying the boards, apply a layer of waterproof coating over the entire surface to cover the boards and gaps. This provides double waterproofing and ensures no water seepage. IV. Three Common Mistakes, All from the Hard-Won Experience of Construction Workers These mistakes are very common, and although they seem minor, they are very troublesome to fix later. Pay attention during construction and avoid them: 1. Using ordinary cement mortar to stick the boards (the biggest mistake) Many workers take the easy way out and use cement mortar, but it doesn't stick the XPS boards firmly. After a while, the boards will fall off. Always use the special glue we recommend from Longer. Its bonding strength can reach over 0.8 MPa, which is sufficient for all scenarios. Don't skimp on this. 2. Inadequate sealing of board gaps, leaving gaps or not filling them completely Board gaps are a major area for water seepage. Either they are forgotten or the sealant is not filled completely, leaving small gaps through which water can seep in. For wet areas, it is recommended to apply sealant to the board gaps first, and then add a layer of waterproof tape. This provides double protection and you don't have to worry about water no matter how much you use. 3. Not leaving expansion and contraction gaps, causing board bulging XPS boards expand and contract with temperature changes. Although the movement is not significant, if they are installed without gaps, when it gets hot, the boards will bulge and deform, causing the tiles to crack. In addition to leaving a 2-3mm gap between the boards, also leave a 5mm gap between the boards and the wall. Fill the gaps with sealant. It's simple and effective. V. Longer's Exclusive Tips, Double the Construction Efficiency After years in this business, we have summarized two tips that have been tested in actual construction sites. New workers can use them to work faster and better: On cold days (below 5°C), preheat the special glue indoors before using it. Don't use it directly outdoors, as it will cure too slowly and affect the construction progress. For large-scale construction, don't rush. Do it in sections, and check each section as you go. Don't wait until the entire area is done to find problems. It's much more troublesome to fix them then. In fact, Longer's XPS tile backboards are designed for convenient installation. The high-density extrusion process makes them light, hard, and they come with built-in waterproofing and insulation. They are much lighter than traditional cement boards and can be carried by one worker. The construction efficiency can be increased by 40%. If you have any questions during the installation process, whether it's about choosing the boards or applying the glue and laying the boards, feel free to contact us. Our Longer technical team will provide one-on-one answers. You don't have to figure it out on your own. Good boards with proper installation can last longer and avoid rework. I hope this useful article can be of help to all the masters!
