Mapei Flexcolor CQ smell/offgassing

Against my wishes this product was used, it had an extremely strong latex/chemical odor for the first day. It has dissipated quite a bit, but still smells 3 days later. I have severe allergies so things like this I am exquisitely sensitive to. Any idea on if this smell is going away, or how to help it dissipate?

Also, they did not follow instructions and steam cleaned the floor with a steam mop 2 days after application- which the product explicitly states not to do for 7 days. I wonder if that will ruin the cure and has to be re-done? Some companies, such as "AFM Safecoat" make non toxic grout sealers. Should I consider this?

Thanks.

Cleaning with a steam mop after that short of a time could be problematic. They state to keep DRY for seven days....not 2 days, not four days. SEVEN days minimum. Hopefully it will dry out and be good. Only time will tell.

Alex, I wouldn't put any sealer on that floor. Is it possible to slightly open a window, maybe with a small fan blowing outward?

Welcome, Alex.

What is the application for this tile and grout?

If you paid to have this tile installed I recommend you invite the contractor to remove it if it looks the tiniest bit suspect. Actually, I think he should replace it regardless any suspect look. I don't know what that steaming might have done to the grout.

You do not need nor do you want to use any kind of sealer on that grout.

My opinion; worth price charged.

I know, I sure hope so. It smells better today. Yesterday was intolerable. I am hoping that it just needs a few more days to fully dry out.

@davy
I have the window open, a carbon air purifier in the room, and I am letting it dry out as best as I can. I will install a box fan now to push the air toward the window. Thanks!

@cx
This was for a bedroom to grout ceramic tile.

That's where it gets complicated. The contractor didn't do that, my crazy mom did. When I heard the steamer going I tried to stop it as quickly as possible, but she had already steamed the majority of the floor 48 hours after it was grouted.

Should I consider running a high end dehumidifier in the room?

The smell is definitely more tolerable today. I really wish we had just used appropriate grout for my sensitivities, but that's a whole different subject. If I stick my face into the grout right now and smell, the smell bothers me. Yesterday it hit me as soon as I went into the room. So it's better, but definitely not ideal.

Well, I suppose you could make your mom re-grout it, Alex.

Sorry but this picture came to mind when I read that.

Alex, I would give it a few more days to dry out on it's own. I bet it'll get better.

If your face is looking like that picture of Mrs. Doubtfire, you’re doing it wrong.

On a serious note, I think it’s going to continue dissipating over the next couple weeks until it’s no longer noticeable.

I agree with the others it should keep off-gasing less and less over time.

I also just wanted to mention MCS is often from Liver phase 1 going too fast, and Niacinamide (has to be that exact version of Vitamin B3) can really help many people with this, though it is a bit of a bandaid fix.

Hopefully its already better today. Best wishes

Thanks for the info. Did you get that from Andy Cutler? I am familiar with your suggestion, I do have severe MCS, I don't tolerate niacinamide but grapefruit products supposedly do the same thing, I will get back on grapefruit. I really appreciate it!

We're off topic (my fault) so I will send you a PM about this, but I've used this to help many people and seen tons more be helped by it, and yes correct about the Grapefruit. Sorry to hear it is severe, I had it in the past myself so know how it feels

It still smells. Can the floor be regrouted or does the entire thing have to be ripped up to the concrete and redone? What a disaster.

Only other option is to try the sealer, which you all seem to not suggest doing with this grout. I just don't see this dissipating to my sensitive nose any time soon.

Please call Mapei’s tech line and ask them. They have a great team. I’d be surprised if they can’t give you some useful info on the timeline of curing. This product needs to dry and I think you just need more time.

In the meantime, I’d advise against trying cover it with any sort of a sealer.

Hi Alex,

The Latex odor should dissipate in about 3 days

MAPEI Flexcolor CQ cures faster in lower humidity
conditions (less than 50% is ideal).

Give Technical Support a call at 1-800-992-6273 for our recommendations as far as sealers are concerned

We'd be more than happy to help you out.
