Do I need Backer Board when installing tiles for a kitchen backsplash?
August 28, 2010
Currently the wall is finished and painted and we want to install tile to update the look.
If we install tile with backer board, I have a feeling the tiles going to stick out a lot.
Is backer board necessary or can I scruff up the painted wall, add the thinset and place the tile?
Do I need a sheet of membrane behind the thinset and tile or is this mainly for bathrooms?

You don t need any thing behind the tile on a back splash other than the painted , clean dry wall.
This is classified as a non wet area and will be fine. You have your choice of using a modified thin set or a mastic..
The backer board is totally unnecessary in this area. All this in accordance to ATC and TCA tile code hand book.
Any questions you can e mail me through my avatar and check my qualifications there. GL

Remove at least 75% of the paint and add a waterproofing admix to both the adhesive and the grout and you should be fine.

I have to agree with Ray that a sheet of membrane is a good idea because while it may not be classified a wet area it does get quite wet sometimes and it is better to be safe than sorry.
I like is Durock Tile Membrane. It is a moisture-proof barrier that looks like it could be great for bathroom and basement tile projects. Durock Tile Membrane is fast curing and easy to install because it comes on a roll but doesn’t curl back up like you would expect. I think it is an easy and cost-effective addition to any tile project.
