Waterproof Roof Coatings and Sealants

Yes, 100% silicone formulations such as SiliconEx 500 are specifically engineered with hydrophobic properties that resist permanent ponding water without softening or delaminating. Unlike standard water-based acrylics that may degrade under continuous standing water, moisture-cure silicone provides an impenetrable barrier suitable for low-slope and flat roof decks.

Our coatings adhere to a wide array of roofing materials. Compatible surfaces include metal, concrete, wood, asphalt shingles, built-up roofing (BUR), modified bitumen, and single-ply membranes such as TPO, EPDM, and spray polyurethane foam (SPF). Surfaces should be clean, dry, and structurally sound prior to product application.

Cure rates vary based on ambient temperature and relative humidity. For elastomeric waterproofing products like SealEx 100, skin-over typically occurs within 4 to 6 hours, achieving a full cure within 24 hours. Fast cure times reduce downtime and protect the newly coated surface from unexpected weather exposure.

Specialized acrylic sealers such as ShinglEx 800 bind loose granules and penetrate weathered asphalt shingles. Lab testing demonstrates an 88% reduction in granule loss. The waterborne acrylic film provides essential UV protection to slow sun-induced aging and color fade, significantly delaying the need for complete roof replacement.

Most coatings are formulated for versatile application using standard contractor equipment. Depending on project size, they can be applied using a commercial airless sprayer, heavy-nap roller, or brush. For larger projects, airless sprayers operating at 3,000 PSI or higher ensure uniform wet film thickness and rapid coverage.

Yes, products are packaged to support both job-by-job maintenance and large commercial installations. Available package sizes include 5-gallon pails, 55-gallon drums, and bulk pallets containing 36 5-gallon pails (180 gallons), as well as 265-gallon totes for select restoration coatings.
