Sanded grout is usually installed from the joints between ceramic or porcelain tiles. Over time, grout may develop cracks and chips, or can become discolored and require repair. You can also replace all the grout between the tiles with grout of a different color simply to modify the look of the tiled area. The job is time consuming, but also a specialized instrument helps you avoid damaging the shingles while accelerating the work together.
Hold a grout watched by the plastic handle and position the blade against the damaged parts of grout. Saw back and forth into the esophagus line between the shingles, removing the damaged grout plus about 2 inches of postoperative irritation on either side of the damaged area inside the grout lines. Eliminate any other damaged areas of grout in an identical manner.
Wipe down the damaged areas with a damp grout sponge to remove any dust or residue in the grout lines.
Pour a small quantity of sanded grout of the same color as the installed grout to your 5-gallon bucket. Add water to the bucket and mix the grout with a trowel until it reaches a thick and smooth, but not soupy, consistency.
Expand the grout in the bucket above the washed grout lines using a grout float. Utilize the tile into the grout lines completely, then wipe away the surplus from the room together with the float.
Gently wipe the area around the grout line having a moist grout sponge. Allow the grout to set for about 15 minutes then rub it down again to level the esophagus to the desired depth in the joint.
Enable the grout to dry for 24 hours, then wipe the entire area with a sponge and clean water. Following the water dries, buff the shingles as well as the grout lines with a thick terry cloth towel to remove any final grout residue from the shingles.
