Best Acrylic Waterproof Coating Manufacturer 452%

BOSLAI Acrylic Waterproof Coating (Acrylic Elastic Waterproof Coating) is a single-component emulsion-type waterproof coating formulated with pure acrylic polymer emulsion and other additives. Once cured, the waterproof coating forms a waterproof membrane with extensibility, plasticity, crack resistance, and weather resistance, providing functions such as waterproofing, seepage prevention, and protection. This coating has good temperature adaptability, is easy to use, and is convenient for maintenance and repair.

FAQ

Can acrylic waterproof coating be applied on wet or damp surfaces?

Yes. BOSLAI acrylic elastic waterproof coating has excellent breathability, meaning it can be applied on slightly damp substrates without trapping moisture beneath the coating film. This makes it especially suitable for exterior walls and roof applications in humid or rainy climates where complete surface drying is difficult to achieve.

What is the difference between acrylic and polyurethane waterproof coating?

Both are water-based, eco-friendly options suitable for indoor and outdoor use. Key differences:
Acrylic offers superior UV and heat resistance (stable from -30°C to 80°C), making it the preferred choice for exterior wall applications exposed to direct sunlight.
Polyurethane delivers higher tensile strength (≥6.74 MPa vs 1.3 MPa for acrylic), giving it better mechanical performance for high-stress substrates such as bridges and tunnels.
Acrylic is more cost-effective for standard roof and wall waterproofing projects.
Both have excellent elongation (≥352% for PU, ≥452% for acrylic), so both accommodate minor substrate cracking.

Is acrylic waterproof coating safe for indoor applications?

Yes. BOSLAI acrylic waterproof coating is eco-friendly, non-toxic, and contains no detected VOCs. It is safe for use in enclosed indoor spaces such as bathrooms, kitchens, and bedrooms. Workers can apply it without the need for respiratory protection. The cured coating is harmless to humans and pets.

Can this coating be used for swimming pools and water tanks?

Yes, with proper finishing. BOSLAI acrylic coating is impermeable at 0.3 MPa for 120 minutes and performs well under submerged conditions. Its excellent temperature adaptability (stable from -30°C to 80°C) also makes it suitable for water tanks exposed to temperature variations. For permanent submersion applications such as swimming pools and water tanks, a concrete topping or tile layer must be applied over the coating film for long-term surface protection.

How many coats are required, and what is the recommended coverage?

Two coats are recommended for standard waterproofing applications. Each pail (18kg/20kg/50kg) covers approximately 13–15 m² per coat. Allow 8 hours for surface drying and 23 hours for thorough drying between coats. For high-stress areas (basements, tunnels, or zones with significant substrate movement), three coats are recommended.

What surfaces does BOSLAI acrylic waterproof coating adhere to?

BOSLAI acrylic elastic waterproof coating bonds strongly to concrete, cement mortar, brick, tile, and existing coating layers. Its pure acrylic polymer formulation provides reliable adhesion without a primer on standard cement surfaces. For smooth or non-porous substrates (glass, metal, glazed tiles), a primer is recommended to ensure optimal bonding.

What are the application methods and special usage tips for this coating?

BOSLAI acrylic waterproof coating is designed for flexible application:
1.Can be applied by sprayer, roller, brush, or scraper
2.Can be diluted with water for easier application on large surface areas
3.Compatible with fiber mesh for reinforced waterproofing on high-stress zones
4.Can adhere directly to concrete, metal, tiles, glass, wood, and existing coatings without primer
5.UV resistant—suitable for outdoor exposure without additional protective layer

How does BOSLAI acrylic coating perform in extreme temperatures?

BOSLAI acrylic elastic waterproof coating maintains stable performance across a wide temperature range from -30°C to 80°C. It passes low-temperature flexibility testing at -35°C with no cracks, making it suitable for cold-climate applications. Its UV and heat resistance also ensure long-term outdoor stability without degradation or chalking under direct sunlight.
