I just used the Mapei Grout Refresh product yesterday and it worked great. Much easier than I thought it would be to apply.

Krud Cutter also works well. Spray on, wait about a minute, stuff brush 3-4 swipes, and wipe off with a clean rag. You'll need a lot of rags since wiping off with a dirty rag isn't very effective.

Krud Cutter looks like a cleaner, where as the Grout Refresh product is a stain/colorant and sealer that matches the Mapei grout color product line.

KC sounds like a great step 1 to clean, with Grout Refresh (or Custom Building Products’ version) being step 2 for getting the color where you want it.

You're right, it is. I have used the Mapei stuff and am not super impressed with it. Adhesion was very good and it has held up for the last 2 years, but it looks like a bit like paint to me. Applying it took absolutely forever too. I would only use it again if I had some exceptionally super nasty stained grout that I couldn't stand.

Thanks for sharing your observations. I’m happy to hear that it’s held up well (my primary concern). I do like the appearance because I have a relatively thin 1/8” grout line and I used their Ultracolor FA (fine aggregate) which to me looks nice without the coarse sanded grout (do not like that appearance).

No problem. I used the Grout Refresh on a new install because the grout dried lighter than expected and varied a fair amount. The Grout Refresh, while an extra step, made the final product look amazing (color was what we wanted it to be and it was 100% consistent throughout the room).

If you’re really precise or “anal retentive” this type of product really helps you dial in the color if the grout application or cleaning effort comes out more varied than you’d like.
