I need to know if I should caulk the 1/4" expansion gap at the wall.

I'm re-tiling because all my tiles done last year right over the wood floor are coming up in the kitchen. This time I'm adding a layer of 3/4" plywood with backer board on top.

I've read that I need to leave a 1/8" gap between the boards and 1/4" at the wall. I can caulk (and tape) the area between the boards, but most websites say not to cault the 1/4" at the wall. My contractor says that will allow water in. Also there will be 3/4" plywood and then perhaps 1/2" backer board and then 1/4" tile, leaving a deep gap. We kind of compromised that he would caulk just the part where the tile is.

I'd am wondering whether that's the best approach. Should I put a baseboard around the edge of the tile (the contractor wasn't planning to)? Am I right in insisting the deep gap not be filled? It is OK to just caulk the top 1/4"?

Fill the gap if it will be visible. If you put a base molding up, no need to fill it. The gap is required to allow movement of the wood in the walls. Caulk is pliable enough to allow that movement.

make sure not to use acrylic/latex caulks.

Becasue they allow more movement before the bond breaks, I would only use a 100% silicone caulk/sealant such as you might find here:


There are two ways to do any job. The right way and the wrong way. Do it right everytime.
