Home > Media > News > Industry News > How to Tell Genuine and Fake Waterproof Flooring at a Glance for PurchasersWith the surging demand for flooring installation in humid environments, waterproof flooring has become a "must-have category" in the flooring market. However, the market is flooded with the concept of "waterproofing", mixing low-cost and inferior products with truly high-performance waterproof ones, making it difficult for practitioners such as general distributors, home furnishing mall purchasers and wholesalers to distinguish them.
A slight inattention may lead to pitfalls. For professional purchasers, "telling genuine and fake waterproof flooring at a glance" is not only the key to reducing operational risks, but also the core capability to build a good reputation and increase profits. DOMOTEX asia/CHINAFLOOR, the flagship exhibition of the Asia-Pacific flooring industry, will kick off in Shanghai from May 27 to 29, 2026. It will gather more than 1,500 high-quality flooring brands worldwide, focus on displaying market-proven waterproof flooring products, and allow purchasers to conduct on-site hands-on identification, serving as a core position for precise product selection and avoiding fake products.
Genuine waterproof flooring must have testing and certification from authoritative institutions, which is the primary "passport" for identifying authenticity and the easiest dimension for purchasers to verify quickly.
When identifying products, professional purchasers will prioritize checking two core certifications:First, the special certification for waterproof performance, which must comply with national standards such as GB/T 40856-2021 Determination of Water Resistance of Resilient Floor Coverings, with clear marking of water absorption rate (for solid wood flooring) or for resilient flooring;Second, the comprehensive certification for environmental protection and quality, such as ISO 10582 waterproof testing certification and China Green Building Material Product Certification. Some high-end products also pass international certifications such as EU CE and US ASTM, providing double protection for product performance.
Counterfeit products often use "self-made test reports" and "vague certification names" to muddle through. Purchasers need to note that formal certifications will mark the full name of the certification body (e.g., China National Building Material Test & Certification Group, SGS), certification standard number and detailed test data, which can be traced and inquired through the official website. If only vague expressions such as "waterproof qualified" and "industry-leading" are marked without specific data and traceable certifications, the product is most likely a fake waterproof one. The exhibitor brands at the DOMOTEX Exhibition have undergone strict screening, and all displayed waterproof flooring can provide complete certification documents. Purchasers can verify them on site without worrying about the fake certification trap.
The core competitiveness of waterproof flooring lies in its craftsmanship details. The gap between genuine and fake products is reflected in the visually visible design and material, and purchasers can quickly distinguish them through "observing, touching and checking".
Genuine waterproof flooring will be optimized in structure with targeted measures: resilient flooring adopts fully sealed lock joint technology with waterproof coating or silicone strips at the lock joints, achieving seamless splicing; solid wood flooring undergoes deep carbonization and wax sealing treatment, with waterproof coating on both the edge and back of the board; stone plastic flooring (SPC) optimizes the substrate formula and adds a high-density waterproof core layer to prevent water penetration. In contrast, counterfeit products only spray ordinary coating on the surface without exclusive waterproof structure, leaving easy gaps after splicing.
Purchasers can touch the surface and cross-section of the board on site: the surface of genuine waterproof flooring is smooth and dense with uniform waterproof coating and no graininess; the cross-section is compact without pores or delamination. Counterfeit products have rough and easy-to-peel surface coating, and loose cross-section with even obvious pores, making water easy to seep in. The DOMOTEX Exhibition provides on-site sample experience, allowing purchasers to directly touch and disassemble the samples to intuitively feel the craftsmanship gap between genuine and fake waterproof flooring.
Professional purchasers can quickly verify the waterproof performance through simple on-site testing at the exhibition, which requires no complex equipment and can produce results in 1 minute. It is also the most direct way to see through counterfeit products.
Take a product sample and continuously sprinkle water on the surface and lock joint connection with a watering can for 1 minute, then observe the state of the water: the water on the surface of genuine waterproof flooring will roll off in the form of water drops without penetration or residue, and there is no water seepage trace at the lock joint connection. For counterfeit products, the surface water will spread and penetrate quickly, water is easy to accumulate at the lock joints, and even traces of water seeping into the interior can be seen.
Immerse the edge of the board in water for 5-10 minutes (can be quickly operated with a water cup at the exhibition site), then take it out and observe: the edge of genuine waterproof flooring has no expansion, warping or discoloration; counterfeit products will have swollen, soft and darkened edges, and even delamination and peeling. High-quality waterproof flooring brands at the DOMOTEX Exhibition often set up on-site testing experience areas at their booths, where purchasers can operate on site to intuitively verify the product's waterproof performance.
The durability of waterproof flooring needs to be verified over time. The industry reputation and actual cases of a brand are important references for purchasers to avoid short-term "fake waterproofing" products.
Brands that truly focus on waterproof flooring often have a long history of participating in the DOMOTEX Exhibition, and can provide long-term application cases (more than 1 year) in scenarios such as hotels, bathrooms, basements and outdoors, showing the use effect of products in real humid environments. In contrast, counterfeit brands mostly participate in exhibitions temporarily with no core cases, and only attract purchasers with the gimmick of "low price and waterproofing".
Professional purchasers will learn about the actual user feedback on the brand's waterproof flooring through industry exchanges and dealer reputation, and verify the brand's after-sales policy at the same time: genuine waterproof flooring brands will provide a clear waterproof performance warranty (usually 3-5 years) and promise to replace or refund the product if water seepage problems occur; counterfeit brands have no clear warranty and even do not provide after-sales support. The Buyer Club of the DOMOTEX Exhibition provides purchasers with brand reputation references and precise docking, helping purchasers choose reliable brands with guarantees.
The core reason for the difficulty in distinguishing genuine and fake waterproof flooring in the market is the lack of a platform for centralized comparison and professional verification of high-quality and inferior products. As the largest professional B2B flooring exhibition in the Asia-Pacific region, DOMOTEX asia/CHINAFLOOR fundamentally solves this pain point for purchasers.The more than 1,500 flooring brands gathered at the exhibition have all undergone strict screening. Waterproof flooring products are required to provide complete certification documents, craftsmanship instructions and case proofs, eliminating "fake waterproofing" products from the source.
The exhibition sets up an exclusive display area for waterproof flooring, covering all categories of waterproof products such as resilient flooring, solid wood flooring and outdoor flooring, allowing purchasers to compare the waterproof performance, craftsmanship and prices of different brands in one stop.At the same time, the exhibition holds concurrent events such as the Flooring Innovation Summit and the Waterproof Flooring Technology Forum, inviting industry experts to interpret the testing standards, identification methods and application trends of waterproof flooring, helping purchasers improve their professional identification capabilities. The Buyer Club also provides personalized docking services for purchasers, accurately matching high-quality waterproof flooring brands, allowing purchasers to efficiently select truly high-performance waterproof products without comparing prices and identifying products everywhere.
Identifying genuine and fake waterproof flooring does not require complex equipment or professional knowledge. The core lies in "grasping the key points and conducting simple verification":First, check authoritative certifications (traceable with data);Second, inspect craftsmanship details (waterproof structure, material texture);Third, conduct on-site testing (water sprinkling, immersion);Fourth, verify brand reputation (cases, after-sales service). These four dimensions are interlocking and can help purchasers quickly eliminate counterfeit products.
From May 27 to 29, 2026, DOMOTEX asia/CHINAFLOOR in Shanghai will create an "On-site Comparison and Identification of Genuine and Fake Waterproof Flooring" for flooring purchasers, allowing them to master identification skills through hands-on operation, and at the same time connect with high-quality waterproof flooring brands worldwide to achieve precise product selection and profit making while avoiding pitfalls. For professional purchasers, choosing the right platform is the key to avoiding the "fake waterproofing" trap from the source and safeguarding the professional reputation and market competitiveness of procurement.
