Exploding floor

Posted by jmagerl on March 9, 2008, 1:36 pm

I've posted about this before, every winter the ceramic tile in my kitchen
pops off the floor (thinset over plywood).
At first I thought it was temperature because it usually occured on the
coldest day of the year. But what about humidty, can the dry air of winter
cause a plywood sheet to shrink enough to cause the tile to pop off?

Its too late for this year, the damage is done. but next year I will be
having a humodifier going to test the theory out.

Even though the manufacturers say you can thinset over plywood, it's
generally a bad idea. Tile is very stable, tile is not. If you don't
want to use backer board, you should use a cleavage membrane.
