Can You Epoxy Over Wood or Plywood?

Yes. A wood or plywood subfloor can be coated if the wood is sound. Wood moves more than concrete, so the system uses a primer made for wood and a flexible base coat.

Prep for wood and plywood

  • Sand or grind the floor. The coating needs a fresh wood surface to bond to.
  • Do not coat plywood that is rotting or breaking down. Replace it first.
  • Wood soaked with harsh chemicals or animal fat cannot be coated.

Timing

  1. Day 1. Prep and roll the primer. It needs 7 to 10 hours before the next coat.
  2. Day 2. Roll the base coat. Topcoat it 3 to 6 hours later.
  3. Day 3. Walk on it 24 hours after the topcoat. Full cure takes 2 to 7 days.

Coat when the room is between 55 and 90°F.

What it costs

A 200 sq ft room takes one 1 gal kit of P-015 ($79.99), one 2.5 gal kit of B-933 ($209.99) and one 2 gal kit of T-444X ($309.99). That is $599.97, or about $3.00 per sq ft.
