## Description

Tapel Liquid Rubber Waterproof Sealant - 3X Stronger- Black 1L - Professional Grade Roof & Concrete Coating, Indoor/Outdoor Leak Repair, Crack Filler, Weather-Resistant Protection: desertcart.com: Tools & Home Improvement

Review: We were impressed - This stuff works great. I guess I was not paying attention when I ordered it. I was thinking it was gallon size, but was quart size. I needed to fix a leak on the top of my cargo van and it did a great job. It spread out and covered all the seams and dented areas on the top of my van.
Review: Heavy-Duty Fix for Leaks & Cracks - This sealant saved my leaking roof! The 35oz black formula is 3X thicker than others—applied easily with a brush, forming a rubbery waterproof layer. Sealed cracks in concrete and stopped gutter leaks. After 6 months of rain/sun, no peeling or cracking. Professional-grade but DIY-friendly—even covered 120 sq ft with one jar!

## Features

- ✔ MULTI-SURFACE WATERPROOFING — STOPS LEAKS ON CONTACT: This black liquid rubber creates a seamless waterproof membrane for roofs, concrete foundations, metal gutters, wood, PVC pipes, and more. Bonds instantly to seal active leaks and prevents future cracking caused by moisture intrusion and temperature swings.
- ✔ NO MIXING, DIY-FRIENDLY APPLICATION: Ready to use straight from the bucket — no mixing, no special tools required. Applies like thick paint with a brush, roller, or pour method. Self-leveling formula automatically fills hairline cracks under 1 mm, making it ideal for homeowners and DIY repairs.
- ✔ FAST CURING FOR QUICK PROJECT TURNAROUND: Reaches 90% cure in about 2 hours at temperatures above 50°F (10°C) and becomes walkable within 24 hours. Designed for efficient repairs without long downtime on roofs, basements, or outdoor structures.
- ✔ ALL-WEATHER ELASTOMERIC PROTECTION: Flexible, UV-resistant coating expands and contracts with seasonal temperature changes. Tested to withstand heavy rain, snow, ice dams, salt spray, and pool chemical splashes, maintaining long-term waterproof performance without cracking or peeling.
- ✔ WATER-BASED, ECO-SAFE & HIGH COVERAGE: Low-VOC, water-based formula safe for fish ponds, greenhouses, and residential environments when fully cured. 1 kg covers approx. 2 m² per coat, delivering higher coverage efficiency than traditional asphalt-based waterproofing products. Remains flexible for 5+ years.

### ⭐⭐⭐⭐ It Doesn’t Work On Tires …
*by M***N on July 25, 2025*

but it does a pretty good job on the old yellow rain slicker. Just be careful not to sit on anything until it’s dry. I was unsuccessful at getting it off my car seat.
