Liquid Silicone Waterproofing Coatings

Liquid silicone adheres to a wide variety of roofing substrates, including weathered metal, concrete, masonry, wood, and single-ply membranes such as TPO and EPDM. It is also compatible with spray-applied polyurethane foam, modified bitumen, asphalt surfaces, and existing roof coatings, making it suitable for extensive restoration projects.

Unlike water-based acrylic coatings that can soften or delaminate under standing moisture, liquid silicone possesses naturally hydrophobic chemistry. It cures into a seamless barrier that provides resistance to permanent ponding water, preventing moisture penetration even in low-slope roof areas prone to continuous water pooling.

Yes. Liquid silicone formulations feature high solar reflectivity, functioning as cool roof coatings. By reflecting solar radiation rather than absorbing it into the roof deck, they lower thermal load on facilities, helping reduce interior cooling demands and utility costs during warmer operating months.

Liquid silicone coatings are single-component and solvent-free, requiring no separate catalyst mixing on-site. Applicators can apply the coating directly using heavy-nap rollers, commercial brushes, or professional airless spray equipment across properly prepared substrates.

To accommodate various project sizes, liquid silicone coatings are supplied in multiple packaging formats. Options include 1-gallon containers, 4 to 5-gallon pails, 55-gallon drums, and large-scale bulk configurations such as 180-gallon pallets or totes for high-square-footage installations.

Applying a liquid silicone coating system allows facility owners to rejuvenate aging roof membranes instead of funding an expensive, disruptive tear-off. The seamless moisture barrier halts weathering, renews waterproofing integrity, and is available with manufacturer material warranties up to 20 years.
