Question- Removing Subflooring
I have a question about removing the subflooring in my bathroom in order to install new subflooring/backerboard/tile. I have removed the old tiles and the cement backer already but am now at an impass as I realized that the screws that held the backerboard to the subfloor where longer than they should have been and have gone into the joists(?) underneath, making it extremely difficult to pry up the subflooring. What techinque/tool shouls I be using for the job?
Your responses would be greatly appreciated.
