How To Use A Grout Sealer

Once you have gone through our top ten list of the best grout sealers and have purchased the one that best suits your needs, it’s now time to put that sealer to good use. And to do that, you are going to have to take the time to read the product’s instructions and take the time to seal the grout properly. To help you use your grout sealer properly, we wrote the following guide that we hope is quite useful.

Step One: Read Instructions

Even though we just stated in the above paragraph that it’s important to read the instructions on your grout sealer, we feel that it’s worth repeating here. If there’s anything that you come away with from reading this article, it should be this: Make sure that you read and follow all the instructions on your grout sealer—particularly, the sections on safety. To not read or follow the directions is merely setting yourself up for failure, so make sure that you take this step seriously.

Step Two: Gather The Equipment You Need

The next thing you need to do before you begin to seal your grout is to gather up all of the equipment that you’re going to need to get the job done. Generally speaking, this usually includes things like safety equipment meant to protect your skin from these products, but it also means additional tools that could make the process of applying the grout sealer a lot easier. Below is a shortlist of some of the items that you need and/or may find useful when using a grout sealer.

  • Nitrile Gloves
  • Knee Pads
  • Paper Towels or Lint-Free Cloth
  • Grout Brush
  • Grout Cleaner
  • Paint Brush

Step Three: Clean Your Grout

Okay, the next step that has to be done before you can seal your grout is to clean it. Make sure that you use your favorite broom or shop-vac to remove all of the debris off of the floor, and then when that’s done, go ahead and grab your favorite grout cleaner to use. Although some people use just any old household cleaner to clean their grout during this process, we find that a real grout cleaner provides better results. There are quite a few great grout cleaner brands on the market nowadays including Black Diamond, Granite Gold, And Rejuvenate, so be sure you use one that you feel confident in using. Once you’ve secured your cleaner, follow the directions on it, and then use it and your grout brush to remove all of the dirt off the grout’s surface. After that, you merely have to wait for the tile grout to dry. Of course, if you’re in a big hurry, you don’t have to just sit idly by. Instead, you can speed the process up by having a fan blowing over it.

Step Four: Tape Off Surfaces

Before you begin the grout sealing process, it’s usually a good idea to tape off the areas that you don’t want to come in contact with the sealer. This includes baseboards and metal finishes that you want to avoid getting sealant on. Once you’ve taped off those areas using painter’s tape, look over everything one more time before you begin sealing your grout to make sure that you didn’t miss any spots. When that’s done, it’s time to seal the grout.

Step Five: Seal Your Grout!

With the floor properly cleaned and dried, it’s now time to begin the actual sealing process. Make sure that you place your nitrile gloves on to protect your hands and place the sealant in an applicator bottle if that’s the method you choose for applying the sealant. If you’re using a sealant that comes in a trigger bottle, then be sure to spray it on the grout evenly and according to the label’s directions. If you’re using a product that has to be applied with a brush, then be sure to apply the product to the grout evenly for the best results. No matter which way it’s applied, however, your goal should be the same. It should be to cover the grout completely from the tile edge to the tile edge.

If you happen to spill any of the sealants onto the tiles themselves, be sure to wipe it up as quickly as possible using your paper towels or microfiber cloth. You’ll want to make sure that you clean it up before it dries on the tile, because if it does, then you’ll have a real mess on your hands. When the tile grout begins to darken and takes on a wet look, then you know that you have applied enough sealant to it.

Step Six: Apply A Second Coat & Allow It To Dry

Once you’ve finished doing all of the grout, it’s time to give it time to dry before applying a second coat. It’s usually best to wait for 30 to 60-minutes before applying the second coat, but be sure to follow the directions on your specific sealant’s label to be sure. After 2-3 hours, the surface of the floor should be able to tolerate traffic, and after about 12-hours you’ll be able to mop it in most instances. After a full 24-hours, the tile grout should be completely dry and can be used as normal. Congratulations! You have just sealed your grout.
