Airkrete and moisture
I recently had air-krete installed in my new home which is under construction. Construction on the outside included OSB sheathing, rigid foam insulation, and a housewrap. I am confident drying from the inside to the outside is minimal if non-existant.
On the inside wall airkrete was sprayed in. A housewrap was put over the drywall side of the studs to keep the air-krete from falling out during installation. In accordance with standard AIr-Krete installation, the inside house wrap was slit 4-inches horizontally approximately ever 12-inches vertically. This was to help the air-krete dry.
According to Air-Krete the drying time should be 2 days. A week went by before my drywall started installing sheetrock on the walls. He did not notice any moisture. However, and approximately two weeks after the Air-Krete was installed, we found a stud needed to be installed on a wall to support a shower door. The housewrap was slit at that location, and the Air-Krete removed.
The Air-Krete was moist, like moist sand. It did not “drip,” but stuck together due to the moisture content. My drywall contractor was very concerned the moisture will damage the drywall, especially future installation of mud and tape. I contacted AIr-Krete headquarters and they have suggested installing a dehumidifier and heaters and stopping the drywall installation for at least a few days to let the Air-Krete dry.
I guess my question is, does this seem normal? Could I purchase a moisture meter with a probe and stick it through the installed drywall into the Air-Krete to see if it is dry, so I can verify the mud and tape can be installed since the Air-Krete is dry? And where do I get such a probe? I have seen meters for checking the moisture content of wood and drywall online, but they have short prongs. I know this may sound silly, but would a soil probe which measures moisture work?
Any help or guidance on what I should do next will be appreciated?
