Almost anybody with tiled flooring in their home has had to deal with grout that is cracked, stained, or damaged in some way. Often this is due to the imperceptible floor movement that happens bit by bit over a long period of time. Other times it is an unfortunately hasty installation that is to blame. But whatever the cause, learning how to repair floor grout yourself instead of calling in a professional will mean you save money and gain a valuable, new skill in the process. Keep reading below for a few things that are must-haves before you get started on your floor grout repair project.
Of course, before you begin to apply the new grout, the old will have to go. Manual grout removal tools are inexpensive but tedious, and you may find yourself worn out within minutes. Heavier power tools, on the other hand, usually aren't best for first-timers. An oscillating tool with a grout removal blade, then, is the best compromise. It allows for a perfect balance of control and power, meaning you can have your damaged grout out of the way without the headache. Pair the oscillating tool with a sponge and pail, vinegar-water mixture, and an industrial vacuum cleaner, and your floor will be spotless in preparation for the application of new grout.
The most obvious piece of the puzzle when repairing grout is the new grout itself. But don't rush to the store and buy just anything. Make sure the new grout's color is matched precisely to the grout already between the tiles (take a sample into the store to ensure the best match), and that it is compatible with your floor type. Marble floors, for example, will require unsanded grout so as not to do any significant damage. Premixed grout is best for beginners, but don't forget to pick up a trowel and rubber float to apply it smoothly and effectively.
After the old grout has been removed and the new grout applied, it's time to make sure you won't have to repeat the job any time soon. Buffing rags made of soft cotton are perfect for cleaning the new surface without the risk of scratching it, and grout sealer applied with a small brush is all you will need to finish the job. Simply allow it to dry, and you can enjoy your good-as-new tile floor without worrying about grout damage getting worse.
