I'm putting a backslpash up, it's stone tile. the tile is made up of individual natural stones, like river stone. They're heavy and the space is pretty big-5 7'.
My question is, can this go over just drywall? I know most backsplashes go over drywall, but I had a contractor recommend putting concrete board up instead, to secure it better. and can that backer board go over drywall? Or should I take drywall out?
Concrete board is always better with stone backsplash but drywall will work if it's installed properly just make sure the drywall is prime complete and save yourself some time. If you insist on using concrete board you should remove the drywall to gain as much space behind your kitchen Taps as possible
The simple answer is yes but there are some considerarions to make first. One is the height of the wall stone you are applying and the type of application. Having a five feet height with out extra support only leaves the strength of the exterior drywall paper converting to hold the walls stone. This is why concrete board is recommended and what we use when possible. We prefer to start from scratch so we know what we are dealing with. Second if you are using a wet mortar tthis further worsens the issue. You are best to apply a moisture preventing paint and metal lathe directly into the studs if possibly with drywall screws. We have never personally had any issues with this type of application. The extra steps are easier in final application, longevity and freedom of mind. We also recommend contacting the supplier or manufacturer of the stone as different stone from different areas have different reactions to application methods and cleaning products. Hopefully this helps with this part of the application. As an extra hint apply the stone In layers as going to high mat add to much weight and cause the wall to fall making a mess and adding hours to your work.
