Standard: ASTM D4541-17 – Standard Test Method for Pull-Off Strength of Coatings Using Portable Adhesion Testers
Scope: This test method covers a procedure for evaluating the pull-off strength of a coating.
Applicable Products: Applicable to Air/Vapor Barriers and other coatings.
Test Procedure: A 4” bond disk is applied to an air barrier. The membrane is then scored down to the substrate. The pull tester is attached to the bond disc and pulled until the bond disc has achieved an adhesion failure. The maximum force to achieve adhesion failure and failure mode is recorded.
End Result: Upon the completion of a successful test, the weather barrier meets the performance criteria for adhesive strength or does not meet criteria and further remediation may be required to pass.
