ASC 5 Series Acrylic Elastomeric Reflective Roof Coating, White, 5 gal Pail (5.05 Five-Year / 5.10 Ten-Year Variants)
ASC 5 is a white, acrylic-based elastomeric reflective roof coating for waterproofing and prolonging roof life, available in a 5.05 five-year variant and a 5.10 ten-year variant. Each order unit is one 5 gallon pail, and the coating adheres to roofing substrates such as asphalt and metal. Pair repairs with ASC 7 Elastomagic Cement and ASC F Polyester Fabric.
Key Features:
- Elastomeric waterproofing: Flexible, durable acrylic elastomeric formula waterproofs and prolongs roof life.
- Cool white reflectivity: Reflective white finish withstands elongation and significantly reduces roof temperature.
- Two warranty variants: Choose the ASC 5.05 five-year or ASC 5.10 ten-year formulation for the service life you need.
- Rated and compliant: ASC 5 is listed by CRRC and is CA Title 24 compliant.
- Roll or spray: Applies with a heavy-duty paint roller or professional spray equipment.
- Multiple substrates: Adheres to roofing substrates such as asphalt and metal.

Coverage & How Much You Need:
At the recommended rate of 1.5 gallons per square per coat, a 5 gallon pail covers roughly 3.3 squares per coat, or about 1.6 squares with two cross-hatched coats. Divide your roof area in squares by 1.6 to estimate pails needed for a two-coat application.
Fit and Compatibility:
ASC 5 adheres to asphalt and metal roofing substrates. For holes, leaks and cracks, the manufacturer recommends repair with ASC 7 Elastomagic Cement and ASC F Polyester Fabric using the Three Course Installation Method before coating.
Frequently Asked Questions (FAQ):
Q: What is the difference between ASC 5.05 and ASC 5.10?
A: Both are the same white acrylic elastomeric coating; ASC 5.05 is the five-year formulation with 40±1% solids by volume, while ASC 5.10 is the ten-year formulation with 42±1% solids by volume.
Q: What is included in this order?
A: One 5 gallon pail of ASC 5 coating; drums and totes are other packaging options from the manufacturer.
Q: How much area does a 5 gallon pail cover?
A: Applied at 1.5 gallons per square per coat, one pail covers about 3.3 squares per coat, or roughly 1.6 squares with the recommended two coats.
Q: How is it applied and how long does it take to dry?
A: Stir thoroughly and apply with a heavy-duty paint roller or spray equipment at 55°F and rising; allow at least 4 hours between coats and 24-48 hours for full cure depending on weather.
Q: What roof surfaces does it adhere to?
A: It adheres to roofing substrates such as asphalt and metal; surfaces must be cleaned, dried and free of contaminants, and rusted metal should be wire-brushed.
Q: How should repairs be handled before coating?
A: Repair all holes, leaks and cracks with ASC 7 Elastomagic Cement and ASC F Polyester Fabric in the Three Course Installation Method.
Expert Verdict — Reviewed by the SuperArbor Pro Desk
Pick ASC 5.05 for budget-conscious projects and ASC 5.10 when you want the higher-solids, longer-service-life formulation; both carry the same CRRC-rated cool-roof reflectivity. Prep is everything: pressure wash, sweep all puddles and birdbaths dry, and never apply when rain or heavy dew is expected within 24 hours or below 55°F. Build the two coats in cross-hatch fashion and detail seams, holes and cracks first with ASC 7 Elastomagic Cement and ASC F Polyester fabric for a continuous waterproofing membrane. Do not thin the product and do not store it below 50°F or above 120°F.
Wear protective clothing and eyewear with adequate ventilation during application; the product is an eye, skin and respiratory irritant and contains chemicals subject to a California Prop 65 warning.
Order the ASC 5 Series white acrylic elastomeric roof coating in a 5 gallon pail and choose the 5.05 or 5.10 formulation for your project.
