ASTM D4541
Everything you need to know about Adhesion Testing.
Poor adhesion can be the result of improper substrate preparation, the adhesive surface of the material becoming contaminated with water, dirt, oil or grease, improper primer application which includes too little, too much, not properly cured, and in the case of some materials- not being rolled with a membrane roller. In short, if adhesion is used to keep the air barrier in place and to withstand the wind, stack, and mechanical pressures over the service life of the building, the air barrier material requires the proper adhesion. Each material will have a different adhesion value, and this value will change depending on the substrate the material is installed on.
