The slurry is a product based on cement that fills the joints between the tiles and around bathtubs. Over time, the grout around those locations will crack and / or fall. Replace grout around the bathtub is an easy project that will not take more than two hours. The tub will be out of operation for at least 24 hours since the slurry must be dried and cured. Sealing the new grout will add an additional 24 hours to the project.
- Protect the bathtub by placing old rags or some cardboard on the bottom of it, If a tool fall could undermine the bathtub causing repairs or a costly replacement.
- Remove the old grout around the tub and / or tile. Use a knife or spatula to scrape and / or chip off grout joints. Be careful not to chip the tub or tiles around.
- Use a vacuum cleaner to remove any remaining dirt. Remove the cardboard and suck the bottom of the tub area. More carefully clean areas with soap scum for mold and mildew before applying new grout.
- Take a piece of old grout and use it to achieve the same color with the new grout. Depending on the size of the seal tile grout can be with or without cement. If the seal tile grout is 1/8 inch (0.63 cm) or less, you must use less cement. Larger joints need more cement grout. The slurry semen is sandy; you can even see the sand in the grout.
- Pour some grout in a cube. Add some clean water (a little at a time) and mix using a spatula until the slurry has the consistency of creamy peanut butter. Let the grout park for 5 minutes and then remix. Place a sponge in another bucket and fill it halfway with clean water. Now you are ready to place the grout in the joints.
- Use a trowel and apply the grout in the joints around the tub and / or tile. Work the grout into the joints to fill the gap between the tiles and tub. Let the grout parked for about 10 minutes.
- Use a spatula and cut back the grout around the tub gasket. You should rinse the board with tile, so that it does not protrude. Remove the excess water from the sponge and clean grout joints until the gasket surface is smooth and even. This should be level with the tiles. Remove any excess grout on the surface of the tub or tile before it dries.
- Download water bucket and sponge and fill it with clean water again. By now, it must have appeared a haze on the tile. If not, wait a few minutes and use the sponge to remove the haze. Use sponge side at a time. Clean the area around 12 inches (30.48 cm) long with the sponge. Turn the sponge and clean again. Repeat this process for the repaired areas. If mist reappears, clean again with clean water.
- Let the grout dry for 24 hours before applying a sealer.
Tips & Warnings:
- Do not let the grout to dry because it will be difficult to remove.
- Be sure to remove excess water from the sponge before cleaning to prevent discoloration.
- No rinses buckets or wash excess slurry under the drain of the tub to prevent it from clogging.
- Avoid inhaling dust while the grout mixes.
