Epoxy to seal plywoodboat floor.

Since it s the ideal wood for moist or wet conditions it s often used to craft boats boat parts or outdoor furniture in coastal areas. Marine plywood is a type of wood specifically formulated for use in moist or wet areas. But lots of old aluminum boats did nothing but paint the wood and in lots of cases it still lasted 30 years. Epoxy will last longer and yes poly resin will eventually let some water through.

The end grain has been exposed meaning water has crept between the plywood and fibreglass over time. Is there an alternative to epoxy resin for sealing a plywood boat.

The end result is the entire floor is now spongy and most likely rotten. Dip a foam brush into the clear penetrating epoxy. Photo a shows the direct result of not sealing the end of a fibreglass boat deck where it meets the well.
