How to Select Grout

When we are asked “How to Select Grout,” there is never an easy answer. Choosing the right grout and mortar for your floor or wall tile installation is essential.  Whether  you have a DIY job, or a professionally produced project, this is a critical decision. With so many different types of grout available, how do you pick the right one? Check out our suggestions below to learn more about a selection process.

What is Grout?

Before beginning the process of selection, it is a good idea to understand a bit more. Grout is typically a mixture of cement, sand, and water used to fill gaps between tiles, usually in bathrooms, kitchens, and other tiled surfaces. It helps secure the tiles in place and prevents water from seeping through

Where Will the Grout Be Used?

A series of questions need to be answered.


Whether your project is inside or outside will determine if the grout will be subject to freeez-thaw cycles and also UV light attack. Both  of these variables need to be planned for.


A wet environment carries the multiple dangers of mold, mildew, bacteria, etc. The more dense and impervious the grout, the better off you will be.


A floor application will typically need to tolerate more abuse than a wall application. It is true that “abuse” can come in many forms, but floors need  to resist staining, handle substrate movement, resist fading, and fight abrasion. Certainly, these issues manifest themselves more in the floor setting than in a wall application.

Who Will Install the Grout?

Grouting is infinitely  easier than it was thirty or forty years ago. All by itself, YouTube has made the public functionally conversant in a wide range of DIY type projects. But a word of caution – not all grout projects are created equal. A black grout used as a design statement with white tiles will probably be more of a challenge for a DIY person than an off-white grout might be.

What is the Design Plan?

Your overall plan for the tile installation has to dictate how you pair the grout color with the tile color. If you don’t want your tile to stand out from the pattern, we recommend pairing your grout color with the tile color. This way, the eye won’t be drawn away from the pattern that’s found within your grout line. This style works best with neutral tile colors. Especially with white tile, where you want to keep the white looking fresh and clean. Be aware that lighter grout colors like white can show more stains and require more upkeep to maintain.

On the other hand, if you are hoping to create a major focal with this installation, then contrasting the grout and tile colors will probably get that done for you.

Epoxy Grout as the Solution

   Key Advantages:
  1. Durable: Epoxy grout is highly durable and resistant to cracking, shrinking, and crumbling, ensuring long-lasting results.
  2. Stain Resistant : Its non-porous surface repels stains, making it easy to clean and maintain. This is particularly beneficial in areas prone to spills and splashes.
  3. Waterproof: Epoxy grout creates a watertight seal, reducing the risk of water damage and ensuring the longevity of the tiled surface.
  4. Chemical Resistant: It is resistant to a wide range of chemicals, including harsh cleaning agents, making it suitable for commercial and industrial applications.
  5. Color Stable: Unlike cement-based grout, epoxy grout maintains its color over time, resisting fading and discoloration caused by sunlight and cleaning agents.


“How to select grout” should not be a daunting question in the grand scheme of a project. The most basic analysis is to understand the technical performance requirements first. Then, close the loop with your color selection. As always, thanks for reading.
