We have ceramic tile on the wall in the bathroom with a few tiles of color. Hate to change whole bathroom.
With no offense to you or others who answer, the answer truly is NO, not to any satisfactory level! After installing thousands of sq. ft. of tile, and applying thousands of gallons of paint, AND UNDERSTANDING the properties of fired, glazed tile, I share this. It's essentially GLASS. Without much detail regarding color I'm going to assume you're talking about individual tiles interspersed among a base color tile. Also without knowing the substrate, there is an option. If you can match the base color tiles, and live with them, you can use a diagonal grinder to remove the surrounding grout, around the offensive color tiles, chip them out carefully, and after cleaning the substrate, install new. Certainly that can be applied to NOT matching tile pieces as well. Allow the mastik proper drying time, re-grout, and hopefully be OK with it. If that seems too easy, or difficult, you should consider other PATTERN options, since it's possible you'll damage base color tiles, OR, again, see if that base color is still available. For that you may have to go to a manufacturer, which may be difficult since many are in Europe and/or Mexico. Steven Wolf
As Steven mentioned above, there are products out there that would do it, but not to a satisfactory level. There is a grout colorant which isn't that bad, but the epoxy-based paint that they use for the glazed ceramic tiles does not come out that good.
After 19 years as a hard surface flooring contractor, I have to agree with the last 2 answers. Your tile has been fired in a kiln baking on the color. And as stated, the epoxy paints are a quick fix, but don't last. Sorry to say, time to re-tile....
I don't know much about tile.But I've taken a few ceramic classes And I know when you glaze you have to put it in a Fire Kiln. To even activate the glaze. And I was taught if you missed a spot, and was to put more glaze on and fire it again, it could crack or burn the ceramic. I don't know how this works on tile though. (they come already fired from the factory don't they?) Maybe you could remove the current glaze somehow? And then do a glossy paint. Because if tile is anything like ceramics you'd have to take it off the wall and fire it again. Sorry I don't know anything about tile.
You can paint it or change the tiles. I Cr 13;8a
