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?
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?
