Tile Membrane behind kitchen back-splash?
 
Hello!

I am due to install a glass tile back-splash in the kitchen and currently I am finishing the wall. Should I apply a tile membrane? Glass tile says use correct thin-set and that should be all, but with the construction of this house I just wonder if I should add the extra security of more movement separation? I really don't want to develop cracks in tile or grout. Plan is to use Durock Tile Membrane to get me an even smooth substrate to apply to.

All interior walls in this house are 5/8" drywall, don't know why... The original owner also had R-13 insulation in the wall between kitchen and hall bathroom. Also, they had R-13 in-between same bathroom and bedroom on opposite side. I have no plan to put insulation back as the hall bathroom has no exterior walls.

Anybody have experience with Durock Tile Membrane?

I don't think anything is needed, just thinset over drywall.

I'm with Bill. I put a backsplash directly on the sheetrock. Unless you're planning on throwing water directly at the thing on a daily basis, you should be fine. I sanded up the paint to help the thinset stick, and I was really careful to caulk the joint between the tile and the countertop to keep any splashes from running down the back of the cabinets.

What if I want to use it for crack isolation which is one of the other uses its marketed for? I'm not planning for use for water barrier.
