    For the counter top you need to use 3/4 inch plywood. Attach green board to this, using mastic. You will also need to screw the green board to the plywood using special screws. I got this information from a tile installer I used to work for. Be sure to seal the grout.

    Thank you, Anna!

    Hope you haven't completed your project. The 'green board' should read 'cement board'.

    Ty Anna, I'm quite the planner so no, I've not started yet!
