Deck Frame Coating
Waterproof Coating
What It Is
- FastenMaster Deck Frame Coating is a water-based, rubber-like sealant developed to form a lasting moisture barrier over deck framing. It’s made specifically for deck substructure protection — a step above just leaving the wood bare or relying on traditional joist tape.
- Unlike joist tape (a peel-and-stick barrier), this is a paint-on liquid coating that conforms to the surface and gets into hard-to-reach corners where tape often misses, helping keep wood rot and decay at bay.
Key Features
Moisture Barrier Protection
- Forms a durable waterproof seal over framing members to reduce moisture penetration and help prevent wood rot and decay.
- Can protect around fastener heads and exposed edges — places where water tends to enter.
Water-Based & Safe
- No VOCs or solvents — safer in terms of fumes and easier cleanup with soap and water.
- Non-flammable, making it convenient for job site use.
Fast Drying
- Workable in about 20 minutes so decking boards or other components can be installed shortly after application.
- Full moisture barrier typically established in 24 hours under normal conditions.
Easy Application
- Applied like paint using a bristle brush or heavy-nap roller — no special tools required.
- Can be applied in corners and tight areas where joist tape struggles to cover fully.
Coverage
-
A 1-gallon bucket typically covers around 450 linear feet of 2× framing material.
About this product...
Deck Frame Coating is a liquid, water-based sealant that creates a waterproof barrier to protect wood deck substructures (joists, beams, ledger boards, posts) from rot, decay, and moisture, acting as a faster, more efficient alternative to joist tape. Applied with a roller or brush, it dries quickly (workable in 20 mins, fully cured in 24 hrs) and self-seals around fasteners, extending the life of your deck frame.
