How To Grout And Regrout Floor And Wall Tile?

Tiled floors and walls require some care from time to time. They are normally low-maintenance, but things wear out over time. Grout is the substance that fills the gaps between tiles. If your tiles are worn out, or the grouting is not done right, you may want to regrout your floors and walls.

This job can be done by anyone, so you can regrout the tiles at home, yourself, as long as you follow the instructions properly. It’s not a tough job to do at all, and is necessary, to increase the durability and longevity of your tiles.

Grouting and Regrouting

Regrouting has some extra steps you must take, as it involves the removal of any old grout before a new layer is applied. Grouting, however, is a little simpler and is normally done after new tiles have been installed.

  • There are two main types of grout you can use; sanded, and unsanded. The sanded one is used to grout mosaic tiles and marbles and the latter is used to grout vinyl tile, porcelain tile, and most others. However, the former will require you to know how to cut mosaic tiles.
  • You will have to first determine which tile you have installed, before deciding on the type of grout to use. When you go to buy grout, you will find pre-mixed and unmixed grout. Pre-mixed grout tends to be easier to use since mixing grout requires knowledge about the ratio of materials.
  • However, let’s first learn how to remove grout from in between old tiles. Grout is used on all types of tiles, whether it is to grout glass tiles or tiles for the installing backsplash. This material tends to wear out over time, and you can remove it from the gaps with sharp, pointed tools.
  • It is best to first remove grout before you apply new grout, to ensure better quality and color, and provides an even spread all over. Use a knife, chisel or scraper to push out the grout. Work carefully, or you will risk damaging the tiles.
  • This process will take time, as it is very detailed and methodical work. Even if it is a lengthy process, a little patience from you will be required if you want to bring out the best results.
  • Once you have removed all the grout, sweep away the pieces and wipe the floor or wall with a sponge and cool water, to remove any dust or debris. Next, apply a tile sealant, either with a spray bottle or a sponge. Let this dry for 24 hours, before you use any new grout.
  • If you are grouting your floor or wall for the first time, let your tiles dry and set first. It will take around 3-4 days for the adhesive under the tiles to dry. Better adhesives not necessarily take less time. Apply sealant over the tiles, wait 24 hours, and then start grouting.
  • Follow the instructions provided by the manufacturer to mix it if it is the packages that contain unmixed grout. You will not need a lot of grout, as it is only meant to fill the gaps between tiles. Use a float to spread the grout over the tiles.
  • Make sure the grout covers all the spaces between the tiles. When you are done, use the same float to scrape off any excess grout. There will be quite a bit, as any grout that is not in the small gaps is excessive.
  • You can keep the scraped off, excess grout stored, as these can be reused for other projects. Once you have cleaned off most of the grout, take a pen, pencil, or any other object with a rounded end. Use this tool to push the grout down, so it spreads further and fills any holes left out among the tiles. You can find more information on how to clean and remove grout from tiles here.
  • The grout will only take 10-15 minutes to set and dry. Once it does set, you will have to clean the whole surface up, to get rid of any remaining layers of grout. For this, get a bucket of plain water and some sponges. Rinse out the tiles until they look perfectly clean.
  • Give the grout 1-2 days to cure and set. If you have not applied silicone caulk between the tiles and other structures that may be attached to the wall or floor, like cabinets, showerheads, etc. this would be the best time to do it.
  • Do not apply grout to these spaces. Just buy some caulk of the same colour as the grout. Next, use your finger to press down and flatten the caulk, so it spreads out to cover the whole gap.
  • Get a sealer meant for grouts, which you can use in a spray bottle, or with sponges. Apply this sealer onto the grout, to give it more strength. However, you will have to wipe away any sealer that is left on the tiles with a clean, wet sponge, or else, they may get stained.


If you follow all the given steps perfectly, you will find that you have learned how to grout ceramic tiles, glass tiles, and many more. The same processes are used to grout subway tiles, vinyl tiles, and even mosaics. I would also recommend you sealing the grout after grouting to make them more durable.

It is very simple, and easy to do right at your home. So, without the help of a professional, you can give your floors and walls a new look again.
