Steps to Regrout Tile without Removing Old Grout?

Moreover, it comes in different colors and finishes, so you can make your bathroom look more beautiful. Besides grout, the most important thing is the tool that you will use for the grouting project.
A carbide-tipped scrapper is best to remove residues of old grout. A screwdriver can also be used for this purpose. However, the results of using a scraper will be more accurate than using other tools.
For cleaning purposes, you will need a sponge, vacuum, bucket, and brush. The cleaning tools are also important so that the grout residues don’t come in your way and they don’t make your project difficult.
2. Make Room to Place New Grout
Regrouting tile floor does not mean that you will pour the grout directly on the old grout lines and you will not need any preparation for it. You will have to do a little hard work to get rid of the dirty old grout.
You will have to create room for your new grout placement. Use a grout saw to remove the old grout to make 2 millimeters deep space for new grout. While this process, remove the old grout with this tool.
During this process, it is recommended to wear a mask because the dust may cause breathing problems.
3. Cleaning the Tiles
After creating space for the new grout, the space where you are working will get messy and it will be full of dust and particles. If you will not clean the area and start applying the new grout, the results will not be perfect.
Before going to the next step, clean the space thoroughly using a vacuum cleaner. When you have done vacuuming, wipe the floor with a clean cloth to get rid of the small dust particles.
If the area is wet due to mopping, it’s recommended to wait for some time so that the surface gets dry completely and you start your work.
4. Applying the New Grout
When the surface has dried completely, now its step is to start applying the grout into the room that you made for it. Read the manual given with your grout and follow the instructions that are mentioned on the label.
Looking at the directions is good to achieve better results because maybe they have added an important step that is necessary in the project.
However, the general guidelines to put the grout is as follows:
- If the grout you have bought is in powder form, mix it with the steps written in its manual.
- You have to push the grout into the gaps using the grout float; keep pressing firmly during the process.
- The excess of grout should be removed using the flat end of the float.
- Keep a damp sponge or cloth with you during this step and wipe all the extra grout to get the tile clean.
- Carry on the process until all the spaces are filled with the new grout.
5. Cleaning the Tiles after Applying the Grout
The extra grout should be cleaned immediately while putting the grout in the gaps. It will save you a lot of time and you will not put your efforts into cleaning the dry grouts after the floor dry.
So, it’s vital to clean the excess grout while applying the new grout. Make sure that you don’t put too much grout to protect it from waste.
If you want to add a specific color to your tiles grout, you have to purchase the color pigment separately and mix it into the grout before applying it.
6. Seal the Grout
To protect your grout from damage, you should seal your grout. A sealant makes your grout durable and it will last for a long time. Many options of grout are available in the market; you must choose the one which is non-poisonous, unscented, and easy to use.
When you apply sealant on the grout, apply caulk on the corners and edges of the tiles to finish the process. The grouting will become durable with caulking.
If you apply caulking after waiting for one week, the grout will get a chance for setting well. So, try to put caulk after one week.
