When phenalkamine based primer was applied on wet concrete surface and pull of test was done after 7 days of coating the high cohesive strength was found. Also when primer was applied on damp or humid surface no blistering was found on the surface of the coatings. This shows that phenalkamines are not humidity sensitive. In normal case the primer coating is done on green concrete (wet concrete) after 28 days of drying, but in case of phenalkamines you can coat primer immediately, there by saving the time of floor coating.
