## Description

Product description [Product Name]: High-performance polyurethane waterproof coating High-performance polyurethane waterproof coatings have become the preferred material in the field of modern building waterproofing with their excellent performance and wide application fields, providing reliable and lasting waterproof solutions for all types of buildings. [Product Introduction] High-performance polyurethane waterproof coating is a new type of waterproof material developed using advanced synthetic technology. It is made of polyurethane resin as the base material, supplemented by selected additives, fillers and functional additives, and refined through a special process. The waterproof coating has excellent waterproof, anti-seepage, moisture-proof properties, as well as good adhesion, elongation and weather resistance. It is widely used in various parts of buildings that require waterproofing, such as roofs, basements, bathrooms, kitchens, pools, tunnels, bridges, etc., to provide long-term and effective waterproof protection for engineering structures. ‌[Product Features] Excellent waterproof performance‌: Form a seamless and dense waterproof layer to effectively block water penetration, and maintain excellent waterproof effect even under extreme weather conditions. ‌High-strength adhesion‌: It has good adhesion to various substrates (such as concrete, masonry, wood, metal, etc.), ensuring that the coating is tightly bonded to the substrate and is not easy to fall off. ‌Excellent elongation‌: It has good elasticity and can adapt to the tiny cracks in the substrate caused by temperature changes or structural stress, maintaining the integrity of the waterproof layer. ‌Weather and aging resistance‌: Specially formulated, it has excellent UV resistance and aging resistance, is not easy to fade or crack after long-term use, and extends its service life. ‌Safe‌: Low VOC (volatile organic compound) emissions, in line with environmental standards, and has little impact on the environment and human health during construction. ‌Convenient construction‌: Single-component or two-component design, easy to mix and use, can be applied by brushing, rolling, spraying and other construction methods to quickly form a waterproof layer. [Scope of application] Roof and wall waterproofing of residential and commercial buildings. Waterproofing and moisture-proofing of underground projects such as basements, garages, and tunnels. Waterproofing treatment of wet areas such as kitchens, toilets, swimming pools, and pools. Waterproof protection of transportation infrastructure such as bridges, roads, and culverts. Waterproofing of internal and external walls of buildings such as industrial plants and warehouses. [Precautions] Please read the product manual in detail before construction to understand the specific construction conditions and restrictions. Avoid construction in rainy days or high humidity environments to avoid affecting the curing effect of the coating. Store in a cool and dry place, away from fire, and keep the packaging intact.

- Coverage: Each 1000g/32 oz of polyurethane sealant covers about 14 sq ft (1.3 sq m). Apply in 3-5 thin layers. This waterproof coating easily adheres to surfaces, repairing holes, cracks, crevices, tears, and leaks, while sealing any cracked areas. The roof sealant also creates a protective waterproof layer in the treated area.
- Waterproof Agent Tip:Prolonged rainy and humid conditions, along with cooler temperatures, can extend the curing time for the waterproof adhesive.

It took weeks to receive product as if it is in high demand. I'd not know why. I'd have just bought paint. The can was almost half empty and as I said, normal paint would do a much better job. For the price of this item, I'd have bought two gallons of paint. Rip off is what I call this item...
