Over time, the grout in your shower can become discolored, cracked, or even moldy due to constant exposure to moisture. Regrouting your tile shower not only improves its appearance but also helps prevent water damage and mold growth. While this project requires some effort, it’s a manageable DIY task with the right tools and techniques. Follow this step-by-step guide to restore your shower grout to a clean, fresh look.
Step-by-Step Guide To Regrouting A Tile Shower
Step 1: Remove The Old Grout
Start by using a grout removal tool or a rotary tool with a grout removal bit to carefully scrape out the old grout. Be sure to work slowly and avoid damaging the tiles. Remove at least 2/3 of the old grout depth to ensure the new grout adheres properly.
Step 2: Clean The Joints
Once the old grout is removed, use a vacuum or brush to remove any remaining dust and debris from the grout lines. Wipe the area down with a damp cloth to ensure a clean surface for the new grout.
Step 3: Mix The New Grout
If using powdered grout, follow the manufacturer’s instructions to mix it with water in a bucket. Stir until you achieve a smooth, peanut butter-like consistency. If using pre-mixed grout, simply stir it well before applying.
Step 4: Apply The Grout
Use a grout float to spread the grout over the tile surface, pressing it firmly into the joints at a 45-degree angle. Work in small sections to ensure even coverage. Scrape off excess grout from the tile surface with the float while holding it at a nearly vertical angle.
Step 5: Wipe Away Excess Grout
After about 10-15 minutes (or as directed on the grout packaging), use a damp sponge to gently wipe off excess grout from the tile surfaces. Rinse the sponge frequently to avoid spreading grout residue.
Step 6: Let The Grout Cure
Allow the grout to dry according to the manufacturer’s recommendations, usually 24-72 hours. Avoid using the shower during this time to allow the grout to set properly.
Step 7: Apply Grout Sealer
Once the grout is fully cured, apply a grout sealer to protect it from moisture and staining. Use a small brush or applicator bottle to spread the sealer over the grout lines, then wipe away any excess from the tiles.
Step 8: Reapply Caulk If Needed
If the caulk around the shower edges or corners is damaged, remove the old caulk with a utility knife and apply a fresh bead of silicone caulk for a waterproof seal.
