Can I install glass tile kitchen back splash over painted drywall?

actually adding more paint to the area under the tile is pointless. All glass needs to be adhered with thinset, not glue or mastic. They will not stay white, they tend to brown, and they won't last long. The thinset should be white, because it will drastically change the color of the tiles if you use grey. The thinset is what you will be seeing through transparent or translucent tile, the paint under the thinset will not show through the thinset.





Read the instructions from the glass manufacturer, they usually recommend a modified white thinset, this can be purchased at Home Depot, $15 for a 50lb bag. If you want a great looking install, Mapei makes a thinset they call Adesilex which is the only pure white thinset, and it makes for a really great looking install. It also has less sand in the mix, so it's smoother to work with and looks better. No texture visable through the glass.

everyone here is correct, you most certainly can install tile on drywall that has been painted, as long as the paint finish is clean, dry and free of grease, dust and peeling paint.





However, you are asking about GLASS TIlES. Some glass tiles are somewhat transparent. So, if your wall is painted a color that may possibly change the appearance of the glass tiles, I would give it a quick coat of paint to match the glass tiles so you will not have any unpleasant surprises once the tile is installed. Maybe even a white primer undercoat of paint will bring out the true colors in the glass tile. Also, please be certain the tile adhesive color is not going to show through to the glass tiles.Can I install glass tile kitchen back splash over painted drywall?
White latex modified thin set / with the thin set properly combed out and the glass';beat'; or properly set into the mortar will bet fine. Mastics and organic glues are not to be used in setting glass tiles.Any questions you can e mail me thru my avatar and check my qualifications there.. GL
I agree with jakeb, and would like to add that the adhesives available today will allow you to stick almost any thing to anything else. some times the hard part is determining which product is best.
You mean like ceramic or porcelain tile? Yes it can be glued onto painted drywall but rough it up with coarse sandpaper a bit so glue will stick better.
Yes. Shouldn't be a problem.
