Product Overview

I recently tested out Liquid Rubber Waterproof Sealant Multi Surface Leak Repair Coating, and the results have been nothing short of amazing. As a professional reviewer who has tried and reviewed numerous products, I can confidently say that this sealant is one of the best on the market. It has an impressive range of features, including its protective finish for flat roofs, metal roofs, sloped roofs, planter boxes, foundations, sheds, basements, metal, wood, concrete and more.

The sealant is also highly flexible and durable with over 1000 elongation preventing adhesion failure. Its coverage area is also impressive it takes only 1 gallon/30 sq ft 2.8 sq m for vertical surfaces with 3 4 heavy coats to achieve a 30 mil 0.76 mm membrane. For flat/ponding surfaces it s 1 gallon/15 sq ft 1.4 sq m , with 4 5 heavy coats to achieve a 60 80 mil 1.5 2 mm membrane.

What s more, Liquid Rubber Waterproof Sealant/Coating is environmentally friendly! Its water based containing no solvents or VOCs and produces no harmful odors so it s safe for humans and pets alike indoors and outdoors with no special breathing apparatus required. Plus you can use it to bridge joints, seams, vents, gaps and protrusions with Liquid Rubber Seam Tape or Liquid Rubber Geo Textile where possible movement may occur for a bulletproof system!

I found this sealant to be particularly useful for commercial or residential use due to its easy application process all you need is 1 gallon of liquid rubber in original black color and the product dimensions are 8 x 8 x 8 inches with an item weight of 8.69 pounds. The special features include waterproofing along with compatibility to wood, concrete and metal material types as well as a 1 horsepower requirement battery included? No batteries required?
