I'm preparing to lay ceramic tile in my kitchen. There is linoleum currently covering the space. Can I place 1/4 inch board (subfloor) over the linoleum or must I remove it before putting down the new subflooring????
If you're thinking of using 1/4" luan for any part of a tile installation, YOU'RE WRONG.
Remove the linoleum and luan underneath it as Bill said, then Install you're 1/4" backerboard, whether it be CBU, Hardi, DensShield, or the like. Then tile away.
