When you hear grout repair, you might be thinking that it is a hard job to make. Sure, it is not easy but needless to say, you can do it on your own. There are a lot of professionals who can actually do the job, but if you can work on it by yourself, why not not.
DIYers will surely enjoy this activity as it is measures not just their strategic ability but also patience and accuracy. To give you a good start, here is a step by step guide to consider when repairing grout.
Clean the chipped grout using water and vinegar solution
The area with a broken grout should be cleaned using one part vinegar and one part water. Mix the vinegar and water in a bucket or bowl, then using a scrub brush or toothbrush apply the solution.
Once all the grime and dirt are removed, wipe any excess mixture using a clean cloth.
Remove damaged grout using a grout saw
Make sure that 1/8 inch of damaged grout is removed using a grout saw. The grout saw is a handheld blade that perfectly fits between the tiles. They come in different sizes, hence make sure that you are using the size that fits the space in between your tiles. You have to be very careful when scrubbing old grout, as there is a chance that the grout saw may slip on the tile and damage it.
Wearing a dust mask and eye protection is advised to avoid any health issue related to dust particles.
Vacuum the area
Once you are finished removing 1/8 inch of the damaged grout, remove the remaining grout using a vacuum. Using the vacuum from time to time is also a good idea to determine how far you need to go to finish the removal of the 1/8 inch of the grout.
Wet the tiles
Give the entire surface thorough cleaning to make sure that before applying the grout, the entire area is already clean especially the area where grout will be applied. Use a dry towel to dry out the entire area and make it as dry as possible. When using epoxy grout, you have to make sure that the area where it will be applied is completely dry.
Apply the grout
Now that the area is clean and dry, it is time to apply the grout. Make sure that the grout matches the old group for uniformity. Apply the grout using a grout float, groat float is a rubber pad that has a handle and available on most hardware and/or improvement stores. Be generous and ensure that the gaps are completely filled with grout.
Do not worry if grout gets on the tiles as you can clean them up once you are done.
Once the grout is dry and the surface is clean, you can apply sealant for added protection. Do not use until sealant is dry.
