I too used Mapei FlexColor CQ in my resent tile job in my bathroom.

Granted it had a slight smell but, I have no issues with that (allergies etc etc).
I will say the slight odor did dissipate rather quickly.

I personally wouldn’t be to hasty to get to removing grout etc. UNLESS the job didn’t turn out good to start with as the smell will dissipate.

Appreciate the info gentlemen.

I opened the window fully in the room and setup a boxfan with outflowing air.

Mapei CS suggested maximum ventilation and said it can take up to 2 weeks for this to dissipate. I'm on day 7 and it is definitely a bit better today. I think having constant air flow exiting the room with fresh intake will do it.

I'm going to delay cleaning the floors with any liquids for now just in case as I don't want to introduce any moisture until I really get the smell out of here and this thing is 100% cured.

I used to run the technical services department at MAPEI so I have a few years of experience with this product. Flexcolor CQ is an acrylic-based grout. It cures by exposure to air hardening the acrylic, much like paint. As it cures, the smell will diminish each day and more air is better so the ventilation you're doing will help.

The steam mopping at day 2 wasn't ideal but as long as the grout was intact after the installers did it, the primary issue would be a delayed cure of the grout. There shouldn't be any permanent damage from it. It may very well be why it's taking longer for yours to no longer exhibit an odor.

It sounds like you're taking the right steps. I used Flexcolor throughout my home and was very pleased with it. It's easy to clean and the color stays true. Hope you get to where you can say the same.

Never mind all this excellent technical advice, Alex, I think you should still make your mom re-grout the floor!

Dan Marvin's advice on the matter should carry much weight on the issue, by the way.

Thank you Dan. I'll keep the window open 24/7 and the box fan running toward the opening. It is getting better.. still not great for my sensitivities but more tolerable.

I am in south FL and the humidity is nuts here so I may go grab a dehumidifier, maybe that is delaying the curing as well.

@cx
I agree entirely. I only managed to pick out the most tolerable materials for all of the flooring for people with sensitivities, then the brilliant idea to caulk the thing in acrylic of all options somehow became the choice. Mind boggling.

Installed a dehumidifier last night. 55-60% humidity prior. I've pulled it down to 40% ish. I'm starting to wonder if having the window open here in south FL was just bringing in even more humid sticky thick air and delaying the curing process. I'll give this a few days and see how things go.

Update:

Smell is basically totally gone. Dehumidifier helped a lot, I ran it until the room was in the upper 30% humidity- too low for comfort but good for curing this stuff. Appreciate all the help, gentlemen.
