Abstract
A method for improving the quality of a mastic coating system by using a solvent-borne tiecoat, and a solvent-borne tiecoat composition are provided. The tiecoat is applied to a substrate in order to correct substrate deficiencies which would cause premature failure of a mastic coating applied directly to the substrate. The mastic coating is then applied to the tiecoat to yield a superior mastic coating composition.
