How to Choose the Right Grout Color
June 11, 2021
Often times when deciding to do a thin brick project, the hardest part is choosing what color grout to use. This post is intended to help answer the most frequent questions we at Old Mill Brick receive about different colors of grout.
Grout vs. Mortar
There is a difference! The first thing to understand is the difference between grout and mortar. Grout and Mortar are similar but have distinct differences.
Mortar: Mortar is used when building a full-size brick wall. The role of mortar is to stick two materials together, in this case bricks. You can find mortars in a variety of colors, but they can be hard to locate and purchase. Most mortars will come in gray or white.
Grout: Grout on the other hand, is intended only as a filler. Grout tends to be stickier and harder to wipe off when installing the project. But you can easily find a variety of different colors of grout. If you wanted whites, grays, blacks, browns, or even reds you can find those colors in the grout department.
When doing a thin brick project you should use a type-s mortar or a sanded grout to fill the brick joints (spaces between the brick tiles). Both can be purchase at Home Depot, Lowes or your nearest hardware store. When installing a thin brick wall both mortar or grout are acceptable to use. When installing a floor, we would recommend using a grout. The reason you should only use sanded grout for a floor has to do with flexibility. Floors generally tend to flex and move more than walls do. Grouts have more flexibility than mortars and therefore will prevent cracking of the joints when your floors flex and move.
The Impact of Grout Color
Grout will make up about 18-24% of your finished project. Because of this, the color of grout you choose will make a huge impact on how your brick wall or floor will appear. So don’t just skip over the grouting process of your project. Certain colors of grout will make certain aspects of the brick more pronounced or less pronounced. You can change the look of a brick in extremes just by changing the color of your grout. Below are some examples.
Rushmore w/ gray grout

Hanoi Smooth w/ gray grout
