If the spaces in between the tiles in your bathroom and shower are dirty or unsightly, you can do a quick grout repair job on the seams to make them look new again. Cleaning and repairing grouted seams in tiles is an easy DIY job. You can usually complete the job in a couple of hours. This easy to follow how-to guide will walk you through the entire process.

Step 1 - Select the Grout

Purchase grout that matches the color of the grout currently used in your bathroom. Unless you're planning on re-grouting the entire surface, you want to make sure that the new grout color matches as closely as possible.

Step 2 - Remove Loose and Damaged Grout

Use a grout saw to remove the loose or damaged grout in between the tiles. Gently run the grout saw back and forth along the grout seams. Be careful to avoid damaging the tiles.

Step 3 - Clean the Seams

Use a spray bottle and some cold water to wet the areas where you removed the grout. Then take an old toothbrush and scrub the seams. This will remove the grout you freed with the grout saw. Finally, wipe away excess water or grout with an old towel or rag.

Step 4 - Mix the Tile Grout

Refer to the instructions on the bag or box of tile grout you purchased. Follow the directions precisely when mixing the grout. You can mix the grout in an old plastic container or something that you can dispose of later.

Step 5 - Spread Grout

Use the grout float to fill the seams. Try to fill them completely, making sure the grout is as level and straight as possible. Use small edge of the grout float to match the beveled grout surface used on the other tiles.

Step 6 - Clean the Tiles

Working in small sections, clean the tiles with a sponge to remove any excess grout as you go. If you wait too long to clean the tiles, the grout will dry and be harder to remove. If the grout does dry and become hard, use a putty knife or plastic scraper to scrape the grout away. Then, use a damp rag to wipe the loose grout and residue way from the tiles and seams. Allow the tiles to dry before continuing.

Step 7 - Polish Tiles

Once the tiles have dried, take a soft towel or an old t-shirt to buff the tiles where the grout was applied. Sometimes the grout will cause the tiles to lose their luster or shine. If you buff the area for a few seconds with a dry cloth, the shine on the tiles should return.
