SP Primer is a coating primer prepared from a proprietary blend of acrylic polymers and adhesion promoters. SP Primer is asbestos free and meets the requirements of the National Architectural Coatings regulation.
SP Primer improves adhesion of acrylic coatings when applied to single ply membranes such as EPDM, PVC, PIB and Hypalon. SP Primer is also used to prime Tremlastic and Tremlastic S prior to the application of acrylic latex coatings such as Polarcote FR. In addition, SP Primer may also be used over various surfaces such as metal and masonry as a primer for coatings.
