I am stumped with this one.
This basement ceiling is drywall and had these unusual markings all over it. The makings could only be seen well at an angle. I tested for moisture with my pin type moisture meter and it registered 10% at various areas and less at others.
The basement is half finished with carpet and paneling and the other half is unfinished. There was a dehumidifier going full bore at one area and I found one damp carpet area directly to the left of the dehumidifier, all other areas were just slightly damp (<10%) which is typical of this area.
Has anyone seen anything like this before?
