Acid Blocking Primer.
The revolutionary Acid Blocking Primer is a unique water base, acrylic primer designed to block the Metal Effects® Patina Aging Solutions & Activators from reaching the metal or wood surface chosen as a substrate.
Other primers cannot be used because they allow the Patina Aging Solutions & Activators to penetrate through to the substrate. This will disrupt the desired patina color and damage the finish by bringing either rust or tannic acids to the surface. Acid Blocking Primer can be applied using a brush, roller or spray equipment and is suitable for interior/exterior surfaces.
