What are the steps to seal grout?

Grout is an essential component in any tile installation, as it fills in the spaces between the tiles and helps to hold them in place. However, grout is also porous, which means that it can absorb stains, bacteria, and mildew over time. To protect your tile and keep it looking great, it's important to seal your grout. In this article, we'll go over the steps you need to take to seal your grout and keep your tile looking like new.

Step 1: Clean the Grout

The first step in sealing your grout is to make sure that it's clean. Use a grout cleaner or a solution of warm water and mild detergent to scrub the grout lines. Be sure to pay extra attention to areas that have discoloration or stains. Once you've cleaned the grout, let it dry completely before moving on to the next step.

Step 2: Repair any Damage

Next, take a look at the grout lines and see if there are any cracks or gaps that need to be repaired. You can use a grout repair kit to fill in any cracks or gaps. If the grout is severely damaged, it may be best to remove and replace it before sealing.

Step 3: Choose your sealer applicator

Your applicator tool should be customizable for you. Even though aerosol spray-on sealers are commonly used for convenience, there are a few cases where they may not be the best choice:

Wet over both bathroom surface areas to seal larger sections of grout and unsealed tiles quickly with a sponge.

A special applicator brush or speciality applicator bottle with a rolling wheel will seal only those grout lines on glazed tiles that will not adhere to the sealer.

Step 4: Choose the Sealer and Apply sealer slowly and deliberately

Once the grout is clean and repaired, it's time to apply the sealer. There are two types of grout sealers: penetrating sealers and surface sealers. Penetrating sealers are designed to soak into the grout and protect it from the inside out. Surface sealers, on the other hand, form a protective barrier on the surface of the grout.

When applying the sealer, use a small brush or roller to apply it to the grout lines. Be sure to work in small sections and not to get sealer on the tile. If you do get sealer on the tile, wipe it off immediately with a clean, dry cloth.

Step 5: Allow the Sealer to Dry

After you've applied the sealer, allow it to dry completely. The drying time will vary depending on the type of sealer you're using, so be sure to follow the manufacturer's instructions. Once the sealer is dry, you can walk on the tile and use the room as normal.

Step 6: Re-Seal as Needed

The grout sealer will protect your tile for a year or more, but eventually, it will need to be reapplied. To determine when it's time to re-seal the grout, perform a water test. Put a few drops of water on the grout and wait a few minutes. If the water beads up and doesn't soak into the grout, the sealer is still working. If the water is absorbed by the grout, it's time to re-seal.

Sealing your grout is an easy and effective way to protect your tile and keep it looking like new. By following these simple steps, you can keep your kitchen and bathroom tile looking great for years to come.

In conclusion, Sealing grout is an important step to maintain the beauty of your tile flooring and walls in your kitchen and bathroom. It is a relatively simple project that even a novice DIYer can do, but it is important to follow the steps correctly. Grout sealers come in two types, penetrating and surface sealers, it is important to choose the right one and follow the manufacturer's instructions. Remember to re-seal your grout as needed, and to test if the sealer is still working by performing a water test. By following these steps, you can ensure that your tile stays looking like new.
