Are Urestone panels waterproof?
Yes. URESTONE faux stone, faux brick, and faux wood panels are waterproof and exterior ready. The polyurethane core and protective topcoat do not absorb water, making them ideal for rain, snow, splash zones, and even submerged installations when the right adhesives, fasteners, and sealants are used. This also means our panels do not harbor conditions for mold or mildew.
