How to Seal Your Grout

It really doesn’t matter how clean you keep your bathroom if your grout looks dirty and stained. Some types of grout are extremely porous and they allow all kinds of substances to seep into them including grease, water, and oil. This can not only make the grout look dirty, but can also prematurely age the grout. The best way to fight this is by sealing your new grout, once it has cured, and resealing your grout on a yearly basis.

If the grout is in the shower or behind the bathtub, you may need to reseal it even more often than that. Although some forms of grout don’t need to be sealed (for example, epoxy-based formulas), most of the other grouts benefit greatly from the protection of being sealed.

While you might be thinking that this has to be a job done by a professional, in reality, that’s simply not the case. Just about anyone can seal their grout to protect it from the elements and from dirt.

And since you’ve just found out about the top ten grout sealers currently available, I think it’s time that you also learn how to apply this sealant. So without further ado, here are some tips for sealing your grout.

Tools Required

Before you begin this project, it’s important to do two things. First, you should wait the appropriate amount of time to seal your grout if the grout is brand new. After all, it needs time to cure. Once it has cured, you will then need to gather the right tools for the job. Gather the following together before you start:

  • Grout Sealer
  • Small Brush
  • Sponge
  • Cloth
  • Toothbrush
  • Vinegar
  • Dish Soap
  • Distilled Water

Step One: Clean the Grout

If the grout has been freshly applied and cured, then you can skip this step. If your grout isn’t new, however, then you are probably going to need to clean it. If it isn’t cleaned, then you are going to end up sealing in any stains or dirt that may be in it. Make a solution of soapy water using distilled water and dish soap and then dip your toothbrush in it.

Use this soapy toothbrush to thoroughly scrub the grout. Some dirt stains aren’t going to be able to be removed this way, so you may have to use a 50-50 mixture of warm distilled water and vinegar to really get rid of the tough stains. Do this over one line of grout at a time. When you’ve finished, wipe it with a cloth and allow it to dry for at least an hour before continuing.

Step Two: Use the Appropriate Sealer & Applicator

There are different sealants for different types of tiles, so it’s important to use the correct one. If you’re applying the sealer in an area with a lot of moisture, such as your bathroom, you are going to want to choose a sealant suitable for that purpose. Penetrating sealers are ideal for moist locations because as the grout absorbs them, the sealer imbues the grout with bits of silicone or latex to fill in the gaps that naturally occur in the grout.

This helps to keep moisture from going into the grout and forming behind the tiles. A condition which can lead to mildew and can weaken the adhesive which holds the tile to the wall. Membrane-forming sealants are good for a semi-moist area, such as your kitchen’s backsplash, but shouldn’t be used in bathrooms.

Also be sure to use the proper applicator for your project. For areas with thin lines of grout and tiles that are unsealed, you can use a sponge to cover both the tile and the grout at the same time. If you have glazed tiles, however, then you may want to use a brush to apply the sealer just to the grout since it won’t stick to the tile anyway.

Regardless of which applicator you use or which sealer you use, just be sure to thoroughly read all of the manufacturer’s instructions to make sure that you are applying the product in a safe and effective manner.

Step Three: Apply the Sealer

Apply the sealer to small sections at a time and make sure that you move from left to right. This will ensure consistency with your grout lines and will enable you to more effectively seal the grout. Have a dry towel handy just in case you over apply the product and need to wipe some off of the tile.

If you don’t remove these spills off of the tile within 5-minutes, then you may end up with a foggy film that you won’t be able to remove from the surface of the tile, so it’s important to wipe as you proceed with the sealing process.

Step Four: Allow it to Dry

Once you have completed with the first coat, then you are going to want to give it time to dry. Usually, it only takes 60-minutes for a sealer to dry enough that a second coat can be applied, but be sure to consult with your sealer’s instructions to find out the exact waiting time required.

Once you have waited long enough, then you can go ahead and apply another coat. For maximum effectiveness, most grout sealers recommend that you use two to three coats of sealer to receive adequate protection.

Step Five: Test an Inconspicuous Area

Once you have finished with the second or third coat of sealer, you are probably going to want to do a test to make sure it’s offering adequate protection. You can test it by sprinkling a few drops of water on a small portion of the tile. If the water beads, then the tile is protected.

Step Six: Give it Time

Allow your tile to dry for anywhere from 24-hours to 48-hours, depending on your sealer’s manufacturer’s instructions. This curing period is necessary to make sure that the product can offer full protection. Once the appropriate period of time has elapsed, you can then enjoy your newly sealed tile.
