Grouting can be a rewarding task. It’s the last step in a tile job, so you know you’re almost done. And filling the joints with grout brings out the beauty of the tile. But if you’ve ever had grout turn rock hard before getting it off the tile, you know grouting can also be a nightmare.

Temperature and humidity affect how quickly grout starts to harden after you spread it on the wall. And once it does start to harden, you’ll really have to hustle to get it cleaned off the tile and get the joints shaped before the grout turns rock hard. Avoid this problem by grouting small areas at a time. Start by spreading grout onto a 3 x 3-ft. area. Finish grouting, shaping the joints and cleaning each section before proceeding.
