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.

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.

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

Agreed. A few coats of skim coat is the way to go.
