You can do this project the easy way and just call your tile restoration specialists, but if you are a do-it-yourself person then it would be easy for you to replace the grout yourself.
1: The first step is to scratch off the grout from the moldy areas. Be sure to protect your tiles while scraping, you can do this by covering the tiles with a tape that easily comes off without leaving any sticky stains. If there is not much grout that needs to be replaced, you can remove the grout by using any hard metal to do the scraping (a knife, a screwdriver, or a small pipe). Any tool that can scrape the small cracks can get a smaller job done. However, if you need to do a major grout removal and repair, it is advisable for you to buy a grout saw. Grout saws are available online or you can also find them in your local hardware store. They are very affordable! Read the instructions on how to use the saw properly. After that, you
can run it up and down to scrape off the grout lines. Ok grout removed, right? Check!
2: After removing all the grout clean the surface thoroughly and make sure all particle, grout dust and mold or cleaned off entirely.
3: The next step is to mix your grout. To get the right proportions, ask for advice from the hardware store where you purchased the grout or read the instructions on the packaging. Make sure you buy more grout you expect you will need because it is impossible for you to fill up the joints in an accurate manner.
4: Apply the grout into the joint lines of the tiles with the proper grout applicator tool. When you are done applying the grout mix into the joint lines, you should leave it to dry for two hours and then give it a god wipe with a wet cloth to remove excess grout.
5: When the grout is totally dry, it’s time to clean the surface again. You would need a rag soaked in water to do this since you are now removing something in semi-liquid form.
After that you can leave your grout to dry for another 24 hours for it to finally cure. The next day, you will be able to clean it up with a cleaner of your choice and wipe the whole area to remove residue.
