High-Performance Waterproofing Coatings for Every Substrate
Reliable Materials & Professional Support for Every Project
Protect your structures from water damage with our professional-grade waterproofing coatings. Whether you need a flexible acrylic roof coating, a heavy-duty polyurethane waterproofing for vehicular decks, or a cementitious coating for water tanks, we have the right solution. Browse our collection to find liquid-applied membranes that offer seamless protection for concrete, metal, wood, and masonry surfaces.
Why Choose YILICHENG
Certified Performance
All our liquid waterproofing membranes meet international standards， including ASTM C836 (elastomeric coatings), ASTM D6083 (acrylic roof coatings), and EN 1504-2 (concrete protection). Technical data sheets and third-party test reports are available.
Seamless Application
Unlike sheet membranes, our coatings apply as liquids and cure to form a seamless, monolithic barrier with no joints or overlaps where leaks can start.
Versatile Substrates
Our coatings bond to a wide range of substrates: concrete, cement board, plywood, metal, existing roofing, and masonry. Primers are available for challenging surfaces.
Technical Guidance
Not sure which coating chemistry suits your climate and substrate？ Our technical team can review your project specs and recommend the optimal system.
FAQ
Q1：What is the difference between acrylic and polyurethane coatings？
A：Acrylic coatings are water-based, UV resistant, and best for exposed roofs and walls. Polyurethane coatings are solvent-based or two-component systems with higher abrasion resistance, making them ideal for traffic areas like decks and terraces.
Q2：Can cementitious coating be used for drinking water tanks？
A：Yes, our cementitious waterproofing coatings are potable water approved and safe for contact with drinking water when fully cured.
Q3：How long do silicone roof coatings last？
A：High-quality silicone coatings can last 15-20 years with proper application and maintenance, thanks to their superior UV resistance.
Q4：Do I need a primer before applying waterproofing coating？
A：Primers are recommended for porous surfaces (like concrete) or glossy surfaces (like existing paint) to ensure proper adhesion. Check each product’s technical datasheet for specific requirements.
Q5：What is the difference between one-component and two-component polyurethane？
A：One-component polyurethane cures by reacting with moisture in the air, making it easier to apply. Two-component polyurethane requires mixing two parts before application and offers faster curing and higher mechanical strength.
