How long for screed to dry before tiling?

I'm planning to do this myself and need to book the time off work. What's a good rule of thumb?

"As a general rule of thumb, standard sand and cement screed dries at around 1mm per day up to 40mm thickness, then more slowly after that. So a typical 50–75mm screed can take 6–8 weeks before it’s fully dry enough for tiling. Fast-drying screeds can be ready much sooner, sometimes in a few days, but always check the manufacturer’s guidance. The key is making sure the moisture levels are low enough before tiling to avoid future problems."

"20+ days would be a minimum you would allow, but all depends on the screed thickness"

"Good morning.
You'd want to leave it 48 hours, and always use a primer before screeding even if the bag of latex says you dont need it.

"Screed takes 24-48 hours to dry enough to walk on, but full drying for flooring can range from 7 days to several weeks, depending on type, thickness, and conditions; traditional sand/cement dries about 1mm/day (6-8 weeks for 50-60mm), while fast-dry screeds can be walkable in hours or days, with underfloor heating systems speeding things up after ~72 hours."

"if the screen is a fast setting latex you should be able to walk on it and fit the floor within four hours maybe sooner depending on conditions of subfloor"

"Hi I aggree coplete with the advice from DS FLOOR. Depend of rooms temperature and stuff you are to use some of them walking times very fast not is the same as complete set to fit floor on top. Another consideration is time of finish floor to be used as well. Cheers"
