You can usually use the shower 24 hours after you grout. You can wipe the shower down with a towel or a squeegee, either is just as good as the other. They both get the excess water off the tile and neither will mess up your grout. I have not used that particular mixing agent but they are all essentially the same – grout boost, grout admix, etc. All of them are latex-based liquid which ‘seals’ your grout when cured. I’ve heard they work just fine, I don’t use them. I also heard they are a pain to work with (some of them) but do what they are supposed to do. If you use one use it because you want what it offers, not because it is ‘recommended’ by your tile store – they wanna sell stuff, no? Also be sure to follow the directions to the letter with whichever product you choose, no shortcuts with that stuff.

I think you answered my first question, how long after I grout before I can use the shower? We had a fiberglass tub and surround before, but we had it took out and a cast iron tub put in. Then I tiled the surround with porcelain tile. I will be grouting this weekend. We always wiped the shower surround down with the towel after a shower to help keep it clean. So if I wait 48 hours after I grout before taking a shower will it be ok to wipe down the tiles with a towel or would a squeegee be better? I didn’t want to mess the grout up. Also, do you know anything about a product by The Tile Doctor called Grout Admix? Our local tile store recommends it to add to the grout when you mix it to “seal and protect in one step”. It supposed to make it so you don’t have to seal the grout later on down the road because you’ve already sealed it with the product. Thanks for all your help,

I have not used the CEG grout they are currently hawking. I use spectralock and honestly don’t see myself changing that – ever. Unfortunately I really can’t speak to the ease of cleaning nor the durability of HD’s epoxy. If you choose to use spectralock it does clean very easily provided you FOLLOW THE CLEANING INSTRUCTION TIMES and use the cleaning packets included with the kits. It cleans up very nicely and has an 80 minute working time. It’s also sold in smaller units so you don’t usually need to only use half at a time and freeze the other – 80 minutes is a lot of time while grouting. I would use spectralock on it but that isn’t a knock against the CEG – I simply haven’t used it but I do know the spectalock is easy to work with.
