## Features

- ✔ 🔧 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. Bonds instantly to stop active leaks while preventing future cracks – even in -40°F to 300°F extremes.
- ✔ ⚡ DIY-FRIENDLY INSTANT SEAL TECHNOLOGY: No mixing, no tools – apply like thick paint with brush/roller/pour method. Self-leveling formula fills hairline cracks (<1mm) automatically. 90% cure in 2hrs (50°F+), walkable surface in 24hrs.
- ✔ 360° WEATHER WARRIOR DEFENSE: UV-resistant elastomeric coating flexes with seasonal expansion/contraction. Passes 1000hr salt spray test, withstands torrential rains, ice dams, and pool chemical splashes.
- ✔ ✅ ECO-SAFE & HIGH-YIELD COVERAGE: Low-VOC water-based formula safe for fish ponds and greenhouse use. 1kg covers 2m² (1 coat) – 30% more efficient than asphalt-based products. Remains pliable for 5+ years without cracking.
- ✔ 🛠️ Application Tip: Extended periods of rain and cool weather can delay the curing process of waterproof adhesives. It's advisable to apply the waterproof glue during clear, sunny conditions and in an environment that remains relatively dry both before and after application. For optimal performance, the liquid rubber sealant should be applied in temperatures of 10˚C/50˚F or above, including the temperatures overnight.
