For a kitchen remodel, we have removed the tile floor to reveal a layer of 1/2" plywood on top of the 3/4" T&G subfloor - this wasn't an issue with carpet in the adjoining dining room, but we want to install new 3/4" hardwood throughout the kitchen and dining room area. The 1/2" plywood need to be removed so the entire floor can be the same height - problem is, it was glued and screwed to the 3/4" subfloor and when trying to remove it, it sometimes pulls up some of the plys of the T&G subfloor. I need some sort of wood filler for these divots and it must be something that the nails from the new 3/4" hardwood floor can be driven into. I've found many cement based fillers but I'm concerned that they will crack if a nail is driven into it. What about bondo?
