The Waterproof Roof Coating You Need

The GPS RoofSeal™ seamless liquid rubber roofing system is ideal for retrofitting an existing concrete, metal, modified bitumen, spray polyurethane foam (SPF) or aged built-up roofs to prevent leaking or deteriorated. The durable GPS RoofSeal™ membrane instantly forms a highly flexible, monolithic membrane that will conform to joints, fasteners, flashings, and other awkward shapes. This makes the GPS RoofSeal™ an ideal liquid rubber roof repair product.

The GPS RoofSeal™ is full adhered and prevents water from moving laterally underneath the coating. It is environmentally friendly and contains no solvents. This waterproof roof coating product is odorless, non‐toxic and non‐flammable.

GPS RoofSeal™ Acrylic Topcoat is a single component coating which can be brush, roller or sprayed on GPS RoofSeal coating or directly metal, wood, clay or concrete roof decks. It’s an odorless, non‐toxic, non‐flammable coating with outstanding appearance and protection for superior waterproof roof coating. It is mildew resistant and color stable with no sub‐surface bleed‐through under normal conditions.


Corrosion Protection for the Long Run

The GPS RoofSeal™ provides long-term protection for different applications, possessing 800% elongation capabilities. The substrate movement prevents the coating membrane from cracking, and the elongation prevents cracks from bridging in the substrate.

Other Perlastic™ products are UV stable to protect you from the sun, and topcoats are available in various colors. Perlastic™ membranes are repairable, meaning you won’t need total sandblasting or a membrane replacement.
