Dryzone Damp-Proofing Cream 600 ml Sausage is a professional-grade, water-based silane/siloxane treatment engineered to create a new chemical damp course quickly and cleanly. Simply injected into pre-drilled mortar holes using a standard caulking gun or manual applicator, it disperses through the masonry before curing to form a continuous damp-proof barrier.
This trusted, BBA-approved formula works seamlessly in brick, stone, and rubble walls—even in challenging conditions—without requiring pumps or specialist equipment. Its clean, odour-free installation preserves existing surfaces and accelerates drying, providing a user-friendly solution for rising damp remediation.
