100% Silicone Roof Coating for RV & Flat Roofs

- 100% silicone
- 4.75 gallon pail
- No primer for most roofs
Our take
It is the best match for owners with a large roof who want a stated no-primer silicone.
Why it made the shortlist
Countryman Coatings 100 percent silicone roof coating is a high-solids formula in a 4.75 gallon pail. The listing says it bonds to prepared metal, EPDM, fiberglass, SPF and modified bitumen without primer in most applications.
Against Kohree, it offers a larger pail and a single coat application at the recommended rate. Against EverBond, it names its chemistry plainly.
Buyers focused on large no-primer jobs will find it a sensible match.
What works
- High-solids 100 percent silicone
- No primer required for most applications
- Single coat at recommended rate
- Made in the USA
Watch out for
- Silicone does not accept most other coatings
