What Tile Sealer Is

Tile sealers are a type of sealant that is used to protect the tile from staining and fading. They are available in both liquid and aerosol form and work by creating a protective barrier on the surface of the tile.

This barrier helps to keep out spills and dirt, which can cause discoloration or damage over time. Tile sealers also help to make cleaning up spills easier, as they create a slick surface that liquids can’t penetrate.

Types of Tile Sealers

There are two types of tile sealers: penetrating and coating. Penetrating sealers are absorbed into the pores of the tile, while coating sealers form a protective layer on top of the tile. Both types have their pros and cons, so it is important to decide which type is right for your needs.

Penetrating Tile Sealers

tile-showerPenetrating sealers are more durable than coating sealers, and they don’t usually need to be reapplied as often. However, they can’t protect against all types of staining, and they may not be suitable for use on some types of tile.

Coating Tile Sealers

Coating sealers are less durable than penetrating sealers, but they offer better protection against staining. They also usually need to be reapplied more often, but this is a small price to pay for the added protection they provide.

How to Seal Shower Floor Tile

The process of sealing tile is relatively simple and can be done in just a few steps.

  1. Clean the tile surface with a detergent or degreaser. This will remove any dirt or grease that may interfere with the sealer’s ability to penetrate the surface.
  2. Apply the sealer to the tile using a brush, sponge, or spray bottle. Be sure to apply it evenly, and allow it to dry completely before walking on it.
  3. Repeat the process every few years, or as needed, to keep the tile protected.
