Entering the screed after three days or already the next day?

Hello,

I have already researched on the internet: Screed should not be walked on until at least 3 days have passed.
But our general contractor said that the screed (flowing screed) would be walkable after just 1 day.
Is that really okay?

Thanks for your answers!

Of course, one can walk on it after one day, but one should not as otherwise small hairline cracks could occur, the same applies to stress.
Shock ventilation should only be done after 4 to 7 days. I would only walk on it more frequently after 3 days.

I wouldn't do it - in extreme cases, you risk warranty issues, for example with tile installation.

Do what the screed layer says. Also regarding ventilation, heating, etc. Not what is stated on the internet or someone writes in forums. Depending on the screed and the added additives, there are now quite different times. There are actually accelerators that promise walkability after one day.

Maybe you have fast screed. We had that too, it was walkable after 1 day and ready for covering after 10 days. I would also trust the screed installer.

We have fast screed inside. When it was laid, the contractor himself opened the house after 24 hours, all the windows, and also walked around on it. That was necessary. The house was almost 60 degrees inside due to the extremely fast hardening of the screed. It absolutely had to be cooled and ventilated. Otherwise, the drywall would not have survived. Karsten
