Constant exposure to water and sedimentation or displacement of the walls of the bathroom can make grout around the tiles to crack. The slurry in this state must be repaired to keep water away from the cracks. Over time, the water may damage the structure and decompose the underlying layers. This will trigger repairs which could have been avoided than repairing the broken grout. This type of repair is a job that you can do yourself without hiring anyone.
Instructions
- Cut the grout lines with a saw for that purpose. This is a hand tool that has a narrow leaf diamond. The blade is designed to fit inside the grout lines between the tiles. Spend the saw back and forth as much as you can about the old grout.
- Slurry sucked pieces with an industrial vacuum cleaner and wet the tiles with a damp cloth.
- Fill a bucket with 1 gallon (3.78 l) with water to a depth of no more than 1 inch (2.54 cm). Slurry poured into the bucket of a little at a time. Mix the grout in the water with a spatula of 3 inches (7.62 cm). Continue adding water slurry until slightly thicker than a cake mix. The grout should be thick enough to stay on the spatula but as not to spread it.
- Spread grout space between the tiles with a leveling grout. Do not cover larger than 3 by 3 feet (0.9 by 0.9 m) areas. Keep the leveling to 45 degrees and drag on the tiles. Collects excess grout with a spatula and place the surplus back into the bucket.
- Fill a bucket of 5 gallons (18.90 l) with hot water. Dip the sponge in water and wring. Hold the sponge flat on the tile, passing over the grout lines. Apply gentle pressure to the sponge and pass through the grout lines to soften. Spend the sponge horizontally by horizontal grout lines and vertically by vertical grout lines.
- Rinse the sponge often and repeat steps five and six for completion of the grouting.
Tips & Warnings
- If the grout is old and stained, replace the entire shower grout. Cut the grout lines with the specific saw deep enough so that it can contain the new grout.
- You can use a grinder of 4 1/2 inches (11.43 cm) with diamond wheel carbide to the extent that there is enough space between the tiles. Be careful if you use this method to not get too close to the tile, you could break it.
- Do not place grout larger than 3 by 3 feet (0.9 by 0.9 m) areas. The grout dries quickly and is extremely difficult to remove once it has dried.
