I have a H5'xL7' cinder-block wall behind my wood-stove to reduce clearance to the combustible wall. I was planning to cover it with a load of random tile (mostly 12x12 & 16x16) and assorted stone samples (12x12) from a friend who's mother was downsizing her interior design business.
The cinder block wall is not perfectly straight, some of the blocks are maybe 1/4” or so out of plumb with each other. I'm not concerned about lippage or other aesthetic issues, mostly about getting enough of a bond between the wall and the heavier stones. Is there a special thinset that can be used with stone/tile that I can apply relatively thickly? I was thinking of getting a bag of this http://www.homedepot.com/Custom-Buil...&storeId=10051
Considering this is going to be behind a wood-stove, are there any thin-sets that should be avoided? The tile would top out at about 200f under extreme conditions but normally be around 150f or so.
