Good Day,
DFT readings on Intumescent coating bonded to closed-cell polyurethane spray foam with a popcorn surface texture. Following the AMPP Standard for rough surfaces, sections of the wall line inspected.
I need direction, I set my gauge to three layers, my readings consistent 40 1st layer 60 second layer 154 third layer plus or minus 5. Set the gauge again, single layer, reading 38 to 180 mils~
The possibility- applicators coated foam before it was done expanding or the spray foam surface texture is actually that porous to get a good reading
