Coating peels under traffic or cleaning.
Use the site evidence to agree a project-specific method with the responsible engineer, concrete producer, manufacturer or specialist applicator.
Coating peels under traffic or cleaning.
Test pull-off strength and profile; inspect laitance, oil, old coating and mechanical damage.
Poor preparation or a system mismatched to traffic and exposure can cause loss of bond.
Remove loose coating and specify proper preparation, primer and duty-rated system.
Use approved mechanical preparation and contamination removal; inspect before coating.
Document substrate acceptance and bond test results where required.
Do not treat oily or friable concrete with primer alone.
