At what values of residual moisture can a tiler start work?
Our screed still has a residual moisture content of 2.7%CM. Exactly 7 days ago it was 2.8%CM.
The 2 construction dryers are running consecutively.... Why is the screed in our house drying so slowly?
At what %CM can a tiler start his job?
What kind of screed are we talking about? I think 3% for cement and about 2% for calcium sulfate. 1.6-2 for laminate/parquet/vinyl.
It's a cement screed.
Is the heating working already.... Or just construction dryers?
@Roofer The screed heating program is already running. Seems to have been running for 8 days now (gas heating).
2.0% for cement screed and tile, 1.8% for hardwood flooring. For tile, there is an additional adhesive that also has a higher cost. For parquet, you can pre-apply a primer, but it is expensive.
8 days is more like functional heating than drying. Perhaps the drying process is exaggerated (capillary breakdown).
What is your temperature, how humid is it?
The heater goes up to 40 С, keeps the temperature for 3 days and then down again. In any case, the display of the heating system shows drying of the floor as a program. Temperatures in the house you mean? Currently around 22/23 degrees.
