Sanded vs. Unsanded Grout

Alright guys, another week of Designer Diaries is on its way to you.  Up this week is “When to Use Sanded vs. Unsanded Grout.” Now I don’t know about you, but the first time I was asked what type of grout I wanted, I stood there like an idiot with a blank look across my face.  So to prevent you all from dummy inducing blank stares, here’s my cheat sheet for you:


I’m a big fan of tiny grout lines, so we find ourselves using unsanded grout frequently.  It also can be a little easier to work with on vertical surfaces (walls), because it’s a little sticker.  However, if you’re used to sanded grout, unsanded does have a weird consistency that takes a little getting used to.  All grout does shrink a little, so the reason you use sanded grout in larger joints is because the sand helps prevent too much shrinkage.

That’s really all there is to it.  Easy peasy.  As simple as that.  If your grout line is under 1/8″, you definitely want to go the unsanded route.  If it’s 1/8″ or greater, get some sand in there stat!
