Once you have made a ceramic tile drill hole and added a nail, you'll need to plug up the hole. Sealing a hole in a ceramic tile ensures that there is no space for mold spores to form. Ceramic tile is vulnerable to stains and dirt, even when they in the best condition. Preventing dirt from gathering in a ceramic tile drill hole seems like an impossible task; however, you can follow these steps to block unattractive holes in your ceramics and keep them pristine for longer.

Step 1 - Clean the Tile

First clean the tile to not only ensure that you are not sealing mold into the tile, but also to provide the putty with a suitable surface. Grit, pieces of tile from the drilling, and dirt will prevent the putty from sticking fully to the tile.Wipe the surface with a damp sponge, paying particular attention to the hole. Consider scrubbing the hole with a small brush, but always wipe gently. Harsher strokes may cause damage.

Step 2 - Apply the Putty

Once the tile is clean and dry, and apply putty around the edge of the hole. Press the knife against the area of tile with the hole, forcing the putty into the ceramic tile drill hole. Repeat until you have completely filled the hole with the putty. Then use the damp sponge to wipe away the excess putty.

Step 3 - Seal the Tile

Most unglazed tiles require sealant to prevent water damage and stains. Since you have drilled a hole through the tile, you have removed any glazing seal that the tile may have. You need to provide a seal. There are a number of tile sealing products available which can simply be applied over the surface of the tile and the putty.
