We are going to have granite countertops installed in our kitchen.
I am doing the demo of the old ceramic tile tops to save money. The tile
was set in thick mortar on top of chicken wire on top of wooden
boards--not a continuous top. I could leave it like that for the
installers but we still need to use our kitchen, and things fall through
the gaps in the boards. All the boards aren't even in height either--I
guess the mortar took care of the leveling. Anyway, I was thinking of
taking out the boards and putting down a plywood top (a subtop is not
included in the install price). Can I just use some regular old plywood
like sandply or outdoor ply for sheathing? Can it be continuous or is the
slat method better?
