My garage floor is made of wood - apparently a couple layers of ply (painted on top), over some large beams. The wood is in okay condition overall, but it’s damaged in a couple places around the door (where moisture has come in over the years), and there are small holes and panel gaps here and there.
Underneath the garage is a home gym, with the beams exposed as the ceiling. Because the garage floor is not sealed, when rain and snow fall off of cars, it drips down to the rooms below. For this reason, we rarely park cars in the garage.
I would like to repair and seal this (500 sqft) floor, so that I can use it to park wet cars, and to prevent further moisture damage. What are my options? Is it feasible to repair the damage, sand it all down, and epoxy it? Is there a more appropriate sub-floor material, if replacing it is a better option?
