Re: Removing Grout and Adhesive from Wall Tiles
Paint thinner (mineral spirits ) is used to remove cured adhesive from the surface of tiles and tools. Keep in mind that the surface of tile has been sealed with glaze, unlike the back side where the paint thinner can soak into the tile which will likely affect adhesion when you try to reuse the tile. I would recommend only scraping to remove the majority of the old adhesive. To do this the most safe way, build a jig to hold the tile on the face and at least two sides that is secured to a sturdy work bench. Once the tile is safely held, you can work with a sharpened putty knife or even a wood chisel.
To remove grout from the edges, you can usually sc**** it off with the side of a putty knife OR very carefully knock it off with the putty knife and a hammer, working from the face of the tile and out away from the edge.
Expect some breakage, feel blessed if you're able to recover all tiles.
