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.
To tile, or not to tile, that is the question:
Whether 'tis nobler in the kitchen to suffer
The dent and ding of dropped stoneware,
Or to take care against a sea of movement
And by aligning, end them. To tile: to sweep.
Great book. I have a signed first edition. ;)
I guess The Bard was really into home repair. Before Hamlet 2, there
was Romeo and SWMBOliet
But pop! What tile from yonder kitchen breaks?
It is ceramic, and plywood is the sub!
Arise, fair tile, and kill the splendid decor
Who is already spoiled and spread with shards
O Adhesion, Adhesion, wherefore art thou Adhesion?
Deny thy holding and refuse thy task;
or, if thou wilt not, be but stuck my tile,
And I'll no longer be a Sweeper.
