Roof coating designed to stop leaks and resist UV damage, Tapel Liquid Rubber Roof Coating. Long-lasting barrier and quick repairs save time and worry for RV owners and homeowners. Is it the reliable choice for sun-exposed or damp roofs?
⚡ At a Glance
- • Waterproofing Performance: 336-hour immersion-certified barrier (EN 1504-2) that resists 40 PSI water pressure and stops active leaks
- • Best for: RV roofs, metal roofs, sun-exposed concrete, pool liners and basement walls needing durable waterproofing
- • Not ideal for: Applications where temperatures fall below 10°C overnight or prolonged rain prevents normal curing
White liquid rubber coating with lab-certified UV resistance and submarine-grade waterproofing. Fast tack-free curing in warm conditions allows quicker repairs and fewer return visits.
Stop Active Leaks Quickly - with 336-hour immersion-certified waterproof barrier
EN 1504-2 immersion certification confirms sustained water resistance, combined with a measured tolerance to 40 PSI water pressure. The formula creates a continuous, flexible membrane that seals gaps and resists water ingress under prolonged exposure.
Rapidly repairs leaks in roofs, basements and pool liners, making it practical for urgent fixes and wet-area applications. The high-pressure resistance gives confidence for heavy-duty waterproofing jobs.
Long-Term UV Defence - thanks to 2745-hour accelerated weathering certification
ASTM G154 accelerated weathering tests show 2745 hours of exposure, equivalent to roughly 11 years of UV exposure, and a bright white finish that reflects 92 percent of solar radiation. Thermal stability spans from minus 40°F to 248°F.
Keeps metal and sun-facing concrete cooler and protected from UV breakdown, reducing frequent recoats in hot or coastal environments. The bright white membrane also improves reflectivity on roofs.
Fast, Forgiving Application - with instant damp-surface bonding and strong tensile grip
Tensile strength of 5.8 MPa enables bonding to damp concrete, while adhesive grip begins within about 30 minutes. The self-leveling formula cures tack-free in around two hours at 50°F and covers about 21 sq.ft per 35 oz at recommended wet thickness.
Allows repairs without waiting for perfect dryness, useful for emergency patching or quick maintenance. Brush, roll or spray application suits DIY and professional crews, with easy water-based cleanup.
✨ The 4 Key Reasons for Tapel Liquid Rubber Roof Coating
- Lab-certified UV defence - Reduces sun damage and reflects 92% of solar radiation on exposed surfaces
- Instant damp-surface bonding - Enables repairs on moist concrete without long drying delays
- 10-year zero blistering guarantee - Ensures long-lasting adhesion when applied in a three-coat system
- Self-leveling white finish - Hides substrate imperfections and creates a crisp, reflective membrane

❓ Frequently Asked Questions
Q: Can the coating be applied to damp concrete?
A: Yes, instant damp-surface bonding allows application onto damp surfaces, although applying to fully dry surfaces gives better bonding.
Q: How resistant is the coating to UV and sun exposure?
A: Lab testing shows 2745 hours of accelerated weathering, equivalent to roughly 11 years of UV exposure, and the white finish reflects about 92 percent of solar radiation.
Q: Will the coating stop active leaks and submerged water exposure?
A: The formulation is 336-hour immersion-certified under EN 1504-2 and is rated to stop active leaks at 40 PSI, making it suitable for pool liners and basement walls.
🏆 Our Verdict
Suitable for RV owners, tradespeople and homeowners who need a durable, reflective waterproof coating for roofs and outdoor concrete. The combination of submarine-grade waterproofing, strong tensile adhesion and extended UV defence sets it apart as a weatherproofing solution. While the upfront investment may be higher than thin patch coatings, the long-term durability and ten-year blistering guarantee deliver clear value over time.
