So you've finally narrowed down your favorite tile and even chosen the perfect grout color when you're left with a choice you didn't anticipate: sanded vs. unsanded grout. So what is the difference and which is right for you?

From the surface you're tiling to the type of tile you're using, there are many factors that determine whether you should choose sanded or unsanded grout. Even the width of your grout lines has an effect on this decision. Get to know the difference between sanded and unsanded grout, as well as which grout is best for your tile project.

What Is Grout?

Grout is a material that fills the gaps between tiles. After application, grout hardens, connecting the tiles to one another and strengthening the entirety of the tiled surface. Additionally, grout protects the substrate by keeping liquid and other foreign objects from penetrating the gap between the tiles. Grout is sometimes confused for thinset, which is the mortar that holds the tile to the substrate.

TIP: For tile joints beyond 3/8 inch, look for grout that's designed for use in wide joints.
