lutfi

lutfi - per us army coe usgf, for exposed structural components minimum applied dry density is 22 lb/cu ft (paragraph 2.1.1.2)
minimum average thickness is 0.375 inches (paragraph 3.4.4)
works out to 0.69 lb/sq ft (minimum)

slide rule,
many thanks! i was going to estimate about 3 psf and wait to verify.
thanks again

lutfi
lutfi....depends on whether cementitious or non-cementitious binder.
if cementitious (grace monokote or similar), should be between about 22 and 28 pcf. if non-cementitious(cafco blazeshield or similar), will be between about 12 and 15 pcf.
