Sharkskin® Primer/Sealer

Waterborne Semi-Elastomeric Acrylic Co-Polymer | Exterior Primer

SharkSkin Primer/Sealer is a Flexible, Semi-elastomeric, Acrylic Water-based Primer/Sealer Designed to Stabilize Surfaces and Increase the Adhesion of Solid Top Coats, such as SharkSkin Solid Hide Stain.

SharkSkin Primer/Sealer is formulated to promote adhesion to structurally sound surfaces, such as CMU, plaster, and concrete as well as horizontal & vertical wood surfaces.

A unique copolymer design, SharkSkin Primer/Sealer penetrates and seals porous surfaces as well as locks down deteriorating surfaces in order to extend the service life & performance of top coats. It covers the existing finish to seal the edges of peeling and checks old coatings to lock them down for a uniform top coat.

SharkSkin Primer/Sealer remains flexible over the paint’s service life, thereby reducing cracking & peeling of the top coat.
