Duromastic P15 Diamond

Water-Based Polyurethane Membrane.

Duromastic P15 Diamond is a single-component, water-based polyurethane-modified membrane designed for non-exposed wet areas. It forms a flexible, fully bonded, seamless barrier that prevents moisture ingress while remaining durable and odourless, making it ideal for internal and external applications under tiles.

Areas of Use:
• Bathrooms, laundries, and kitchens
• Balconies, terraces, and decks
• Roof areas (non-exposed)
• Planters, retaining walls, and other internal/external wet zones

Application & Coverage:
Apply with a brush or roller in 2–3 coats, ensuring full coverage at 1–1.2L/m² per coat. For porous surfaces, an additional coat may be required. Can be applied over primed concrete, masonry, fibrous cement, or particle board (primer recommended: Duromix Hibuild WBE). Allow 24–48 hours before tiling and 3 days for full cure at 25°C and 50% RH. Compatible with polymer-modified tile adhesives, renders, and acrylic coatings.
