I was dead set on glue down for basement jobs till a moisture test bit me in Dayton last month
I always figured glue down was the safe call on concrete slabs, no pad, no stretch, done. Then I pulled up a failed job in Dayton last month and the slab was pushing 8 pounds of moisture, so the glue never set right and the whole thing curled at the seams. Now I test every slab first and I'm not shy about pitching a floating floor with a vapor barrier when the numbers are bad, what moisture meter are you all trusting on site?
