I am geting ready to lay 4x4 tiles as the surface for my new counter top. Right now I have a temporary countertop that that consists of 1/2 plywood with 1/2 particle board with white plastic coat. Both are screwed together securely and the plastic coat is intact - no water damage at all. Is this a suitable substrate for the tiles? Should I roughen the surface or add more thickness? I will be using a thinset mortar.
The edging of the countertop will be a 1 1/4 copper pipe cut down the middle and fastened to the facing of the cabinet for a nice rounded edge. I am thinking of rounding a piece of wood to it inside the pipe, fasten the wood to the face of the cabinet and then epoxy the pipe to the wood. Anybody see any problems with epoxy-ing copper pipe to wood? I may also use copper nails if required. I will then polish the pipe and perhaps add a coat of lacquer.
