If you’ve been looking at adding new tile to your home, or upgrading tile you already have in place, you probably know a thing or two about grout. Grout is simply the mortar or paste used for filling between the tile spaces. Grout is important to bind materials together and give you a surface that stands up to wear and tear. It’s also important for aesthetic purposes, creating a design you’ll enjoy every day.Tiling 101: A Guide To Grout

The type of grout you use depends on the style, tile color, and type of material selected. The most common types of grout are sanded and non-sanded, each with their own properties.


Non-sanded grout is a cement based grout normally used on smaller tile joints. It is recommended in floor and wall applications where the joint spacing is not more than 1/8th inch. This grout is designed for use in tile surfaces that are dry when the grout is applied. The water retentive additive allows grout to stay moist while being applied until it cures properly. It’s easier to work with on vertical surfaces because it stays in a more solid state throughout the production process.


Sanded grout is used for larger joints. Sanded grout uses a cement based mortar that has small sand grains added to it to help in the setting process. By adding the sand to grout, the mortar is stronger and stands up to more abuse throughout daily living. It is an excellent alternative for natural stone, marble tiles, glass, and heavier tile materials.  This grout is applied to moistened tile and is cured while damp. Depending on the polish of the stone, sanded grout may scratch the surface. If you decide to use sanded grout, be sure to test it before using to make sure it will not scratch your existing floor.


Epoxy grout is quite different than its counterparts. Epoxy grout is made from epoxy resins and a filler powder, which makes it extremely hard, durable, and nearly stain-proof. The bond between tiles is often stronger than the tile itself. However, most installers find it more difficult to use than other grouts. It also has a more plastic appearance, which some people don’t like. It’s also much more difficult to shape and slope, making transitions from tile to tile more difficult. It may slump in the joints after the floor is finished as it cures and loses its volume. It can also take longer to cure, and is more expensive than the sanded or non-sanded alternatives.
