It's a fact, people don't really notice the grout in-between tiles. Even though my previous articles have described every danger and health hazard that can be in the grout, the space they're in is just really small. A lot of people just put off cleaning for a day or so, until it becomes so filthy a total grout replacement is needed.

Now, about the issue of regrouting. How is it done? What type of materials do you need? This article will assume that you intend to do it yourself and will answer these questions.

Before planning regrouting the first thing you have to do is make sure you actually need to change the grout. A lot of grout will be discolored, but that doesn't make them beyond repair. Poke around the internet for some ways to clean dirty grout; there are more than a few online, and I believe I posted one myself at some point.

In general, black is a bad thing when it comes to grout. If the bathroom grout is hopelessly infested with black mold, or if pool grout has black algae, then those are very difficult to remove, and regrouting is then to be considered seriously.

Removing the grout involves a tool called a grout saw. This'll do the trick for most kitchen projects, but for bigger areas like pools, a power tool with a diamond blade should be used to cut through it. Then, with a grout scraper, slowly chisel off what's left of the grout. Using a vinegar solution with water, clean the area and finally, vacuum the remaining grout pieces.

Now it's time to apply the new grout. Simply follow the instructions which are included in the grout, and you'd do just fine. Also, mop up the loosened grout that's scattered all over the tiles with a damp rag. You have now regrouted your tiles.
