Grout takes more abuse than most people realize. It sits between the tiles and handles moisture, movement, cleaning products, and daily wear. Over time, grout can crack, loosen, stain, or disappear completely. Shower corners and wall seams can also open as materials shift. Once that happens, cleaning alone will not fix the problem.
This section covers regrouting, grout repair, damaged seams, missing grout, and worn joints. We also explain the difference between grout and silicone. Each material has a different purpose and should be used in the right place. You will find information about color matching, sealing, resin-based grout, and flexible repair materials. We also discuss why repaired areas sometimes crack again.
Some problems only affect a small section. Other situations require removing more of the existing material. The condition of the tile and the area behind it can also change the repair plan. These articles will help you understand what may be causing the damage. They can also help you decide whether repair, regrouting, or replacement makes the most sense.
