How Do You Repair Cracked Porcelain Floor Tiles?
A cracked porcelain floor tile (or any other kind) looks bad and can even be sharp and dangerous to walk on. In addition, it can ultimately cause damage to the entire floor. This is because the tile-and-grout system on the floor is designed to work together to seal out moisture. A cracked tile potentially can let moisture in, allowing it to get into the substrate and loosen other tiles. Deal with the problem promptly by extracting the damaged tile, replacing, re-grouting as necessary. Scrape the grout saw over the grout lines all around the cracked tile. Scrape it forward and back, applying steady downward pressure to dig down into the grout. Get out as much as you can, taking care not to scratch the surrounding tiles. Set your putty knife into one of the spaces left by the extracted grout, with the tip positioned against the bottom of the tile. Gently tap the putty knife with your hammer. Work your way around the tile, tapping it the whole time, until the tile comes loose and pops out
