Grout Sealing

This article will cover why you need a grout sealer and which one we recommend you purchase. Firstly what is grout?

Grout fills seams between tiles.  Most grout you will be using is called sanded, a grammatically unusual way of saying that the grout contains sand. Sand is used by manufacturers because it is cheap and because it is a good material for what is a simple job of filling in a hole. Grout is not needed to stabilize tile, because flexible adhesive already holds the tile in place without any extra help.

Sand is porous, which means that grout is porous. Once grout has been applied and dried, it is ready to absorb any liquid that comes its way like water. By penetrating the grout with sealer first, you are pre-empting water and other liquids from penetrating the grout.

Below is three types of grout sealer

Spray Grout Sealer ( We Recommend)

You will quickly seal the grout using a spray on application, We recommend you use Sure Seal as it does not effect the tiles that are around the grout. Its easy to use and lasts the longest in our opinion. You can pick up a can at your local craft decor store and apply it yourself. For about $20 it will be the best investment you could ever make

Applicator Grout Sealer

A spray-on grout sealer is an easy, but sometimes labor-intensive application, for grout sealer. The applicator or brush-on type of sealer is used and applied directly to the grout with a roller or with a brush. The sealer is a milky white color and can be applied to clean tiles.

Penetrating Sealer

Penetrating sealer is a type of sealer that is used to penetrate right into the grout. After you apply the sealer, it will soak right into the grout. This type of sealer is great to use if you are looking to apply a different color to the grout or to darker the original color. They will help to create an additional tint on the grout. A penetrating grout sealer makes it much more difficult for staining to occur on the grout from spills.

If you are looking to maintain the color or pigment of your grout, then purchase a non-pigmented penetrating sealer. This type of sealer will still penetrate into the grout but it will not produce any type of gloss.

To end below is a bathroom that we completed in 2011 and only got a chance to grab the photos in February 2016. Sure Seal was used to seal the grout on this bathroom and after 5 years it looks the exact same as when we finished it.
