Duram Adhesion Plaster Primer Overview

Duram Adhesion Plaster Primer is a solvent-based plaster primer designed to penetrate porous masonry, resist alkali, and control efflorescence for a stable, long-lasting foundation. Because it bonds strongly to cement plaster, fibre-cement, concrete, brickwork, gypsum plaster, and composite boards, it enables reliable adhesion for both oil- and water-based topcoats. With quick drying and breathable sealing, projects progress smoothly while finishes remain uniform and durable.
