May national sealants are designed for primerless adhesion. However, there are occasions when a primer may give you the added assurance of a secure bond. This is particularly true with difficult to bond substrates or applications under certain weather conditions. We recommend that you discuss your primer application needs with a May National technical representative prior to use. Some of our products are listed below.
