Spray On Silicone Coatings

A silicone roof coating system is engineered and tested for long-term performance, offering resistance to permanent ponding water, ice damming, thermal shock, and severe weathering for 15 to 20 or more years. Durability depends on the system specification, dry film thickness applied, substrate preparation, and whether installation complies with manufacturer warranty requirements.

Spray on silicone coatings adhere directly to multiple commercial and industrial surfaces. Compatible substrates include flat and low-slope roofs, metal roofing, concrete and masonry surfaces, single-ply membranes such as TPO and EPDM, spray-applied polyurethane foam, asphalt and built-up roofing, modified bitumen, vertical walls, and existing roof coatings requiring rejuvenation.

Yes, high-performance spray on silicone coatings feature permanent ponding water resistance due to their naturally hydrophobic molecular structure. Unlike water-based acrylic coatings that can soften, blister, or delaminate under sitting water, moisture-cured silicone membranes remain chemically stable and fully waterproof even when subjected to standing water conditions on low-slope roofs.

Spray on silicone acts as a cool roof coating by delivering high solar reflectivity, reflecting up to 88% of solar radiation away from the building. By preventing heat absorption into the roof deck, it keeps interior spaces cooler, reduces strain on heating and cooling equipment, and helps lower overall utility costs for facility owners.

Silicone coatings are supplied in various packaging sizes to accommodate projects ranging from localized repairs to large-scale commercial restorations. Packaging formats include 1-gallon containers, 4-gallon and 5-gallon pails, 55-gallon drums, and bulk options such as 180-gallon and 265-gallon pallet totes designed for high-volume airless spray rigs.

Yes, while airless spray application is optimal for large square-footage installations, spray on silicone coatings are also formulated for easy manual application. Contractors and maintenance teams can apply the coating using medium-nap rollers or heavy-duty brushes for detail work, penetrations, parapet walls, flashings, seams, and localized roof repairs.
