Repairing boat floor plywood. Photo d is a piece of plywood from the floor of a boat wreck. Start removing the old damaged material using an electric saw to cut it. Note that even though the plywood has been snapped and left exposed to rain and wind it still holds its integrity. The counter posed grains and strong inter sheet adhesive give this manufactured wood material its strength and resistance to warping.

Step 1 remove the damaged flooring the most common material used for boat flooring is bc plywood and it is also used for fiberglass boats in particular. Plywood is made with layers of wood veneer laid with the grains at approximately right angles and then glued together. Cover the plywood flooring pieces with a fiberglass mat and seal in place using a fiberglass resin. Cut the outline to make the repair patch.

Place the damaged cutout section of the floor on a piece of marine plywood and mark the outline of the piece. Drill screw holes in the dried fiberglass mat. You cannot repair the boat floor while rotten wood remains as it will only continue to rot. This was located underneath a faux teak floor meaning that it is most likely the original plywood used to build the floor of the boat.

If the stringers and bulkheads are rotten get them replaced with fiberglass ones. If you have the means and resources to remove a piece of the boat floor and replace it then that is the best thing you can do for the boat. Drill 1 16 inch pilot holes one inch from edges of the repair patch and start stainless steel wood screws in each hole. Plywood can be repaired if the damaged area is not extensive.
