Bath tile takes a lot of abuse over the years. It gets pummeled with water, soap, and other chemicals. All of this abuse causes the grout to become moldy and worn out. When grout becomes worn, it dries and cracks. When grout is damaged, it needs to be replaced. It is not a fun job, but it is not difficult either. The biggest problem associated with replacing grout between bath tiles is how long it takes. It is tedious, but the following article will show you how to do it properly.

Step 1 - Cut the Grout

Removing grout between bath tiles is a process that is both time-consuming and delicate. In the past, you would use a small chisel and hammer to break the grout; however, this method can damage the tiles. A grout saw is the best choice. Carefully cut the grout as close to the edge of the bath tiles as possible. Repeat the process for the other side of the tile. The oscillation of the grout saw will remove the grout. Use the mini vacuum to clean up the grout.

Step 2 - Clean the Edges

No matter how well you work the grout saw, you will always be left with grout sticking to the side of bath tiles. In order to replace the grout, you will need to remove the excess. Slide the wire brush between the spaces and begin scrubbing it along the edges. The wire bristles will effectively remove the grout that is still sticking to the bath tiles. Use the vacuum to suck up the dust particles, then inspect the spaces. Repeat the process until the sides of the bath tiles are clean.

Step 3 - Wash Down

Next clean the bath tiles with a damp sponge. Let the tiles dry on their own. Removing dust and other particles is important to maintaining a clean grout that bonds correctly.

Step 4 - Grout the Bath Tiles

Applying grout is relatively simple. Mix the material according to the directions if you are not using ready-made grout. Use the grout float to scoop the grout and slap it over the bath tiles. Smooth the grout over the tiles. Use firm, even pressure to press the grout between the spaces. Use a damp sponge to wipe down the bath tiles. Doing so removes the grout haze that may form over the tiles. Use as much grout as needed and wait several days for the grout to dry.
