Grout in 3 hours

[robbieraven]

Just used a rapid set adhesive and I'll protect the manufacturer as to be honest it's pretty good stuff, HOWEVER, I have to question grouting after 3 hours, surely this is going to have an effect on the grout, efflorescence will surely occur. The tiles are not moveable after about 5 minutes but the addy surely has to dry out deep under the tile. Off course it's really great to get in a get a job done in a day, but what do you all think about a set time of 3 hours before grouting?

Cheers RR

I've used slow set loads of times & grouted after 3 or 4 hours so no problems with rapid set.

No secret, BAL ptb, really nice to use although a bit quick on the set 🙂

Most of the time efflorescence is caused by over wetting the grout when washing off. .

Just think over-night at least makes sense, have always waited maybe, that's why I take so long :lol:

Most manufacturers state on the bag grout after 3 hours. ...so I don't think there would be an issue. .

I've never had any grout problems when grouting after 3 hours.

I have always tried to work a job so that grouting is next day, just because i don't like removing spacers to soon

Thats the idea of rapid set, grout after 3 hours.

Iv never had issues either way..... If your called in for a small job to put about 18 tiles back on then its fine to tile them then after a few hours grout....

As for floors I leave till next day
Just done 13m² on Thursday then Friday grouted

I prefer adhesive to be set but sometimes its cheaper and quicker doing it the same day as long as you do a good job

I think you might be getting confused with grouting too soon after fixing with a dispersion adhesive.
