How soon can I use my shower that I recently grouted and tiled? Should it cure first?
It sure looks like you did a beautiful job on your shower, be a crying shame to see all that hard work ruined with stained grout. The glazing agent in the grout needs 8 to 10 days to harden completely. I suggest that you tape up some poly to protect the new grout if you really need to use the shower before the prescribed cure time. A few days of inconvenience is definitely worth not having to scrub and look at stained grout for years to come.
