Tile Sealer

Tile sealer is the process of applying a sealant to tile or stone for protection against staining and corrosion. Natural stone is typically very porous and full of capillaries that stains love to seep into. To protect against stains, tile sealant is important to apply. Not all tiles need to be sealed. If you have porcelain tile or ceramic tile it may not need to be sealed but since this process is simple and relatively inexpensive we always recommend it.

As mentioned above, natural stone is very porous and it is especially recommended to use a stone sealant. Some of the most porous stones include: travertine, marble, and slate. Although granite is significantly less porous, granite sealer is still necessary because granite is most popular for countertops which encounter spills from acidic foods and liquids.

Usually when having your stone cleaned by a tile cleaning company they will seal it. For more information please visit tile cleaning and sealing.

If the stone countertops or stone flooring is not sealed, it will be prone to stains that may not be easily removed without the risk of destroying the surface during the stain removal process. Some of the biggest dangers to your stone are: acids, salts, and oils.

Grout Sealer

Grout is a very porous substance so grout sealer is very important to apply. Without the grout sealant you run the risk of deep set in stains that may not always be removed with grout cleaning and sealing. In some of the worst cases you will need to re grout or grout coloring.

Grout sealer can be applied in two ways.

Brush on:

It can either be brushed on directly to the grout itself with a brush tip. It's important to avoid getting the grout sealer on the tiles.

Spray On:

When applying the sealer this way you don't have to be so cautious about applying the sealer directly on the grout, but you'll have to do more surface cleaning after.

Tile Sealants

You have three types of sealants to choose from: Topical sealers, penetrating sealers, and impregnating sealers. Many other companies use topical sealers, which isn't the best option. We use the latter two.

Topical Sealer: Topical sealers sit on top of the tile, but they aren't the most effective because in high traffic areas the sealer will wear out quickly. This tile sealer will become slippery when wet which can be a reason for caution. This sealer isn't breathable and it doesn't allow water vapor or gases to escape.

Penetrating Sealers: As the name states, this sealer penetrates the surface of the stone. Because it doesn't sit on top like the topical sealer it will last a bit longer, but still wear out relatively quickly. The sealer is breathable, but doesn't penetrate deeply enough to protect your stone against salt attack. It will only penetrate less than 1mm.

Impregnating Sealers: The sealer is the best when it comes to protecting against salt attack and all other threats which can ruin your tile. Impregnating stone sealers penetrate deeply into the pores of the material which bond to the capillaries and repels water and oils from within the material. Because it penetrates deeply it will last longer than both penetrating sealers and topical sealers.

Tile Sealer – The finishes

Finally, you may select the finish of the sealer to give the tile the look you want.

In the sealer family there 3 main type of sealer finishes:

  1. Enhancer – A stone sealer which will ultimately bring back the natural look as it was before.
  2. Wet Look – A stone sealer which will add a "wet look" to your stone. It gives it a permanent shine.
  3. Natural look- A stone sealer basically does not change the look of the stone as it is now.
