How to use grout sealer on ceramic tile.

Only use a tile sealer that is rated for it and grout and then decide if you want a sealer that has a sheen to it. Membrane forming sealer is best used on an unglazed tile as it does not bond to the glaze. Apply pressure to the brush and use a brisk back and forth motion to scrub the grout well and lift any dirt stains or grime from it. It can also slightly change the color of the tiles as evidenced below.

Seal the tile not the grout. Focus on cleaning the grout or the lines between the tiles by dipping a small brush like a toothbrush into the cleaning solution and rubbing the grout. If you see a grout sealer haze on the tiles then you can apply some more sealer to the areas of sealer haze. Many tiles especially natural stone such as slate marble and limestone are porous and need to be sealed.

Porcelain and ceramic tiles are not porous. These products are advised for natural stone ceramic and porcelain tile grout that are in bathrooms and kitchens. Penetrating grout sealers help prevent staining and prevent grease from seeping into the grout while other non penetrating grout sealers form a barrier to protect the grout from water and stains. This will reactivate the grout sealer so that the grout sealer haze can be removed.

Scrub the grout with a toothbrush to remove stains. Some types of these also called tile enhancers can give a glossy or matte sheen to the tiles depending on what you prefer. After you are done sealing the entire area then do a final inspection to check for grout sealer haze or sealer residue left on the tile surfaces. This type of sealant is ideal for floor tiles as the sealant forms a nonporous membrane that allows moisture to seep into the grout though this makes it difficult for it dry.

There are 2 main types of grout sealer membrane forming and penetrating.
