Advise on concrete screed prepu

[merit]

I have a concrete floor to tile
It's been down over a year but ,hers the catch
It's been open to elements for that time as it's a
Garden room with no windows or doors
These have now been installed and it's water tight
How long before tiling
Thanks in advance

You will need to let the moisture dry back out of it, a moisture meter would be best to keep checking to see how quick it is drying out, if you don't have one a very dude way of judging it is to put a piece of polythene on the floor with a paint pot on top and leave it for a couple of days, if there is condensation on the underside of the polythene then there is too much moisture still present

How long has it been water tight for?

A moisture meter as above would help ^^

Would someone be kind enough to offer me some advice for my DIY project. I've got an outdoor concrete slab that my hot tub sits on it's got a polycarbonate twinwall roof over it.
I bought some fully vitrified ceramic unglazed floor/wall tiles that are suitable for outdoor use, to tile the concrete around the tub. Any recommendations on adhesive and precautions I should take in the laying of the tiles would be much appreciated.

Hi only1jdw, not sure if this should have been started as a seperate thread but still on the same lines as the original post.

Just use a good quality S1 flexible powdered adhesive most are suitable for external use. Just try not to install the tiles if temperatures are likely to drop below 5°. Still pretty cold out at the moment.
