Hello everyone,

Unfortunately, I keep hearing different opinions about ventilating after the screed has been laid.

Maybe someone here can help me out.

Our screed has been curing for 8 weeks as of Friday. On the ground floor, we used anhydrite screed to avoid movement joints in the large living and dining area.

The heating program for the screed from our air-source heat pump was gradually increased to 55°C (131°F) after 28 days. During this time, we ventilated regularly.

Yesterday, our tiler measured the moisture level on the ground floor and found 5% residual moisture. Is that possible? Is that realistic? We would now have to turn the heating back on for a week?

We suspect he might just be trying to delay us?!

Or landscaping :P.

The questions about moisture above unfortunately remain unanswered, right?

This has already been answered. There was no F. However, there was also no tile setter. So there was moisture...
