Hello,
I am a female builder from S-H and absolutely desperate. Apart from the fact that I hardly know anything about screed, I would like to turn to you with my problem:
We have been building a small single-family house (135 sqm, solid) since summer. On 17.10.17 our cement screed (6 cm thick) was laid. We have underfloor heating throughout the house. After 2 days we were allowed to walk on the screed and after one week we started ventilating (every morning and every evening 10 minutes of shock ventilation).
Since 15.11.17 the drying program of the underfloor heating has been running and we have always wiped the moisture on the windows, concrete ceiling, and doors with towels during ventilation.
Since 16.11.17 a large construction dryer has been running. And since 23.11. a second smaller construction dryer (one downstairs, one upstairs).
On 04.12.17 a residual moisture of 2.8% was measured in the screed (unfortunately only at one spot). It was a CM measurement. After that we started painting and plastering the walls (probably bringing moisture back in?).
On 11.12.17 another measurement was taken, same measurement technique: in several rooms and upstairs and downstairs: different values between 2.7% and 3%.
We are so desperate! We have to move out of our apartment at the end of December and have already had to postpone our kitchen installation and staircase installation to early January. That means we will probably move in on 31.12.17 without stairs and kitchen and flooring.
Carpet (with adhesive/fixation) is to be laid upstairs and vinyl (with leveling compound / adhesive) downstairs, we will do it ourselves.
But we will never reach 1.8%!!!!? Many say it should have been dry long ago... The screed installer told us that this is strange and we should sometime soon close everything for 3 days, run the construction dryer and heating and not enter the house.
Has the screed suffered the so-called "capillary break"? We are so scared of that!
What did you do, how did you dry, and what were the moisture measurements like?
I am thankful for any smallest help or advice!
Kind regards,
Cara
