Now that you have your new floors installed, or shower walls and countertops you may wonder if the grout should be sealed. Most installers will not seal the grout right away because they will want to make sure it cures completely. But once the grout has completely dried it would be time to apply the sealer to give it the protection it needs.
Grout is a cement based product which makes the grout porous, causing it to absorb liquids if not cleaned up right away. When you use the grout seal it will protect your grout from spills, stains, mold and mildew grow. It will strengthen your grout and slow down the wear & tear. Now, overtime water and grime can penetrate into the grout causing the tiles to crack. Sealing the grout will help reduce the damages and extend the lift of your tile surface.
Exceptions to the Rule
Not every type of grout needs to be sealed. If you are using an epoxy grout it will NOT need to be sealed. The reason is that it is non-porous. This type of Epoxy grout is seen on glass surfaces which helps protect against stains and water. Unlike cement-based grout, epoxy grout remains flexible which makes it less likely to crack and chip.
Types of Surfaces
Certain types of tile surfaces, such as non-porcelain ceramic tiles, do not need to be sealed. For example, most ceramic tiles are finished with a durable glaze that can help protect the surface from stains, so adding a sealer will not be necessary. However, since porcelain tiles are not coated with a protective glaze, these surfaces should be maintained with a protective sealer. If you have natural stone surfaces such as marble, travertine, slate, or granite, sealing the tile surfaces will be necessary because stone is a porous material that is vulnerable to stains and moisture.
Not Sure?…Test the Surface
If you have existing tile surfaces, and you are not sure if its necessary to seal the grout, there is a simple test that you can do to find out. Try dropping a few drops of water into your grout. If you see that the grout absorbs the water, then you will know that it is time to reseal your grout.
If you perform the “water test” and discover that your grout is absorbing water, don’t waste any time. Its time to either replace the grout or seal it.
Frequently, when homeowners think that grout damage isn’t repairable, Swift Flooring Services can reseal to help prevent a costly replacement.
