About Surface Clear HD
WPC100 Surface Clear HD is a heavy duty, silicone-based sealant designed to protect surfaces from discoloration caused by mold, algae, and fungi. Engineered for long term performance, this sealant bonds at the molecular level to create a seamless, invisible barrier that resists microbial growth and blocks water intrusion. It’s safe for both indoor and outdoor use, and once cured, it remains harmless to people and pets.
Ideal for surfaces like brick, concrete, stone, stucco, vinyl, wood, drywall, and tile, Surface Clear HD does more than just protect against moisture. It also plays a role in fire safety by suppressing flame spread on combustible materials. The formulation has been rigorously tested for antimicrobial performance and is especially effective against common discoloring agents like Gloeocapsa magma, which often appears as black streaks on roofs and masonry.
