Installing a Ceramic Tile Backsplash Over Drywall


Installing ceramic tile over existing drywall.

I am planning to install a ceramic backsplash above my laminate counter top in the kitchen over the painted drywall. What kind of treatment is needed for the drywall so that it does not get moist? Also, a quick step-by-step procedure would help a lot, too. -Raj

Hi Raj,

You should be able to tile right over your existing drywall with no problem. Once the adhesive dries and the grout has set, it will be imperious to moisture.

For detailed instructions on how to install a ceramic tile backsplash, check out the following article, Ceramic Tile Backsplash Project, and video, Ceramic Tile Backsplash, on our website.

Good luck with your project,

    For a sink area, you really should be using a “rock board”. Green drywall is not waterproof – it will delaminate just like regular drywall if it gets wet. Green drywall is just more humidity resistant so it is used in bathrooms. I would cut out an area of drywall slightly smaller then your tile area, cut out a piece of tile backer board to fit the cutout area, and shim up the backer board so the tile will sit flush with the surrounding wall. Fasten the backer. The tile will overlap onto the drywall slightly and at the same time seal up the outside perimeter well to prevent water intrusion. No taping will be needed since your tile glue & tile will seal the seam.

    We are wanting to put small tile squares on the back splash in our kitchen. The finish on the walls is a texture that has been knocked down. Can we tile over this or do we need to sand it down smooth.

    we tore out our previous tile backsplash, which was adhered to drywall. it of course ripped up some of the paperr on the drywall. the drywall is still very intact with the exception of torn up paper. question: is it ok to tile over this “disturbed” drywall and should I prep this drywall in any way? thanks.

    Happy Monday. I have a question about one of your videos – the one regarding the backsplash and range hood. It appears that you mortared the glass tiles to the drywall prior to hanging the range hood. Was the hood’s mounting plate bolted directly to the drywall, or is it sitting on top of some glass tiles? I’m getting ready to do a similar project (with Bliss Glass and Stone cabernet-style mosaic), and I’ve been told to not sit the hood’s mounting plate on top of the tiles, but to put the hood’s mounting plate directly on drywall and to mortar the glass tiles around it. Any thoughts on this?

    Thanks in advance.

    Why does it matter what you have behind your tile? Is’nt the tile water resistant? How would moisture get behind your tile?
