Duroprime PU Primer 10LT

Penetrating Polyurethane Waterproofing Primer

Duroprime PU Primer is a single-pack, moisture-curing liquid polyurethane primer designed to enhance adhesion, coverage, and performance of Duroproof PUM and related waterproofing membranes. Its cross-linking technology creates a strong chemical bond with substrates, “locking down” dust and loose materials while providing a secondary penetrative waterproof barrier.

Key Benefits:
• Single-pack – easy to use
• Moisture curing – fast drying and long top-coat window
• Enhances adhesion and coverage of Duroproof PUM membranes
• Improves membrane application and overall waterproofing performance
• Strong, elastic, and penetrative for porous surfaces
• Suitable for above and below-ground applications, including permanent water immersion

Common Uses:
• Priming concrete, cement, and cement render
• Timber, plasterboard, and fibre-cement sheeting
• Brick and blockwork
• Acts as a penetrative sealer before Duroproof PUM application

Note: Use only in conjunction with Duroproof PUM membranes; not as a primary waterproofing membrane.

Size Variation: 4LT & 10LT
