ASC S Silicone Roof Coating, White, 5 Gallon Pail, Moisture-Curing Silicone Rubber
This is ASC S Silicone Roof Coating, a one-component, moisture-curing silicone rubber roof coating supplied in a 5 gallon pail. It restores and protects smooth surface BUR, granulated cap sheet, acrylic coatings, concrete, metal, SPF foam and single-ply membranes. Apply by medium-nap roller or airless spray; cures in 1 to 4 hours.
Key Features:
- High-solids silicone: 99% solids by volume with no hydrocarbon solvents, allowing application in excess of 40 mils in a single coat without blistering.
- Fast moisture cure: Cures at normal temperature and humidity in 1 to 4 hours by reacting with moisture in the air.
- All-weather durability: Resists weathering, aging, oxidation, ozone, UV radiation, wind-driven sand, rain and snow and roof temperature extremes.
- Flexible application: Apply with standard airless spray equipment, a medium nap roller, or a brush for small touch-up work.
- Low VOC: VOC content is less than 50 grams per liter.
- High reflectivity: White coating shows initial solar reflectance of 0.88 and thermal emittance of 0.89.
- Color options: Available in White, CA Gray, CA Tan, Standard Gray, Standard Tan and custom colors.

Expert Verdict — Reviewed by the SuperArbor Pro Desk
For a single-coat silicone restoration over an aged roof, ASC S is a strong choice because its high solids let you build over 40 mils in one pass without blistering. Verify the substrate is clean, dry and frost-free before application, and schedule work so no rain or heavy dew is expected for 24 hours. On low-temperature or low-humidity days, allow extra cure time before exposing the roof to moisture.
Harmful or fatal if swallowed and an eye, skin and respiratory irritant; use adequate ventilation, keep out of reach of children, and consult the SDS before use.
Order the ASC S Silicone Roof Coating 5 gallon pail in White for long-term silicone roof protection.
