Product Description

The Concrete Protector's Liquid Rubber Base (LRB) is a single component, high solids, water inducted, low VOC, environmentally safe, liquid applied hybrid polyurethane protective membrane. This low odor, solvent-free waterproofing membrane can be used indoors or outdoors. LRB bonds permanently to properly prepared and PermaFlex primed substrates such as concrete, wood, aluminum, steel, and some plastics, as well as most standard building materials. Will not blister, crack, peel, or delaminate from exposure to extreme ambient heat or cold as low as -45°F. Withstands hydrostatic pressure and is completely waterproof.
