Pull Adhesion Testing of Coatings on Gypsum Sheathing
The scope of this white paper is three-fold, first, a review of the wind load requirements set forth in ASCE 7-22 and the IBC 2021, and other related wind speed information; second, the math used to translate mph and psf to a value measurable at the lab or small scale level; and finally, the use of pull-off adhesion testing in conjunction with gypsum-based sheathing products and the air and water barrier coatings applied to them.
An Examination of Wind Loads Across Various Standards and the Use of Pull-Off Adhesion Testing to ASTM D4541 and ABAA T0002 to Meet a Desired Wind Load Target
