Sealing Floor Grout

There are a number of reasons why homeowners might decide to undertake the process of sealing floor grout in their home. The process offers them benefits such as:

Having a cleaner home. A home where the grout has been sealed is inherently cleaner than a home where the grout has not been sealed because the exposed pores in the grout can make it more susceptible to allowing mold and mildew to develop. Sealing floor grout covers the pores making the grout impermeable.

Spending less time cleaning grout. Tile floors where the grout has been sealed are easier to clean than floors where the grout has not been sealed because the sealant prevents spills from seeping into the grout.

Simplifying the process of cleaning grout. Sealing floor grout also makes it much easier to clean the grout. The process is simplified because there is no need to spend a great deal of time scrubbing each individual grout line when cleaning the floor because the grout is less susceptible to stains.

When is Grout Sealing Necessary?

If you reading this article you are probably already wondering if sealing floor grout is necessary in your home. In general grout sealing is not necessary when the floor was grouted with epoxy grout and when grout admix was used when grouting the floor. That is because both epoxy grout and grout admix create a nonporous surface when they are applied. The purpose of sealing the grout is to eliminate pores so therefore grout sealing is not necessary in these cases.

Now that we have explained the exceptions to when sealing floor grout is necessary, you might still wonder whether or not it is needed in your home. If you are unaware of the type of grout that was used, you can determine whether or not it is necessary for you to seal the grout by placing a few drops of water on the grout. If the water soaks into the grout, this indicates your grout is porous and is in need of a sealant application.

Preparing the Floor for Grout Sealing

When sealing floor grout, it is important to properly prepare the surface before beginning to seal the grout. This is important because if the surface is not prepared properly the sealant may not be as effective as it could be. The process of preparing the surface basically entails a thorough cleaning of the area.

Start by sweeping the floor. Next moisten the surface and clean in small portions at a time by using a solution of 5 parts water and 1 part vinegar and scrubbing with a brush with stiff bristles. Then rinse the surface with clean warm water and allow the floor to dry completely before beginning the process of sealing the grout.

Choosing an Applicator

When sealing floor grout, the choice of applicator is up to the individual’s personal preference. Some may choose to use small paint brushes to seal the grout. This can be a very time consuming method but there are some who prefer this method. Some grout sealant comes with a built in applicator.

The applicator basically consists of a small modified paint brush on the head of the bottle. This makes grout sealing a very convenient process.

There are also small rollers designed specifically for the process of sealing grout. These rollers are readily available in home improvement stores and often feature a narrow wheel on one end and a wide wheel on the other making it ideal for both wall and floor grout applications.
