Need to grout quickly

I know that adhesive says 24hrs before grouting but I really need to get it done in a hurry.

What's the shortest I could leave it and what are the consequences of grouting over not-set adhesive??

It's flexible adhesive and grout by the way if that makes a difference.

Cheers

About 2 hours if using a rapidset adhesive.

Unfortunately I haven't used a rapid set adhesive.

I have to grout bathroom walls and a bathroom floor.

Well for obvious reason you can't grout the floor until left overnight. The wall tile adhesive can take several weeks to dry out if you grout too soon especially if you have used ready mixed adhesive which relies on the air getting to the adhesive to dry it out.

can cementous adhesives be grouted as soon as they start to set?

i have grouted some walls same day using readymixed. mainly left them till end of the day and got away with it. not something to practise though i would presume.

It depends entirely on the adhesive, for example if using Bal single part flexible there is no way the adhesive will set by the end of the day, Rapidset with say a bed thickness of 3 or 4mm will be OK to grout after a couple of hours.

Ready mixed can go off a lot quicker than a single part although a lot has to do with size of tiles, the bigger the tile the longer adhesive needs.

Also the tile and wall material has a lot to do with drying times, a porcelain tile on a tanked wall will take a while to set.
