Product Details

Ensure the success of your waterproofing project with Duram WB Primer, the professional’s choice for substrate preparation. This eco-friendly, low-VOC primer is engineered to penetrate deep into porous surfaces, consolidating loose particles and "bedding down" dust to create a stable, high-tack surface.

Perfectly compatible with concrete and masonry, it is a critical first step before applying water-based acrylic membranes like Duram Azcothane. Whether you are working on a shower recess, a structural slab, or a large-scale retaining wall, Duram WB Primer enhances the bond of your topcoat, significantly reducing the risk of membrane failure. It is simple to apply via brush, roller, or spray, and offers an economical coverage rate of approximately 4m² per litre, making it both cost-effective and highly efficient for large residential or commercial jobs.
