Black Liquid Rubber Waterproof Sealant - 45oz for Basements & RVs

✔ 🔧 MULTI-SURFACE ARMOR PROTECTION: Tapel's Black liquid rubber forms an impenetrable waterproof membrane for roofs, concrete foundations, metal gutters, wooden sheds, PVC pipes, and more. It bonds instantly to stop active leaks, even in extreme temperatures ranging from -40°F to 300°F.

✔ ⚡ DIY-FRIENDLY INSTANT SEAL TECHNOLOGY: Apply like thick paint with a brush, roller, or pour method—no mixing or special tools required. The self-leveling formula automatically fills hairline cracks (<1mm). Achieve 90% cure in just 2 hours (at 50°F+), and walk on the surface within 24 hours.

✔ 🌧️ 360° WEATHER WARRIOR DEFENSE: The UV-resistant elastomeric coating flexes with seasonal expansion and contraction, making it ideal for long-term protection. This product passes the 1000-hour salt spray test and withstands torrential rains, ice dams, and pool chemical splashes. Tapel's waterproof sealant comes with a 10-year guarantee.

✔ ✅ ECO-SAFE & HIGH-YIELD COVERAGE: Our low-VOC water-based formula is safe for fish ponds and greenhouses. One 35oz container covers 21 square feet with one coat—30% more efficient than asphalt-based products. The sealant remains pliable for 5+ years without cracking, ensuring long-lasting protection.

✔ 🛠️ Application Tips: For optimal performance, apply the waterproof sealant during clear, sunny conditions and in a relatively dry environment. Extended periods of rain and cool weather can delay the curing process. For best results, apply in temperatures of 10°C (50°F) or above, including overnight temperatures.
