PRIMER PU-1000 – High-Adhesion Single-Component Polyurethane Primer
Optimized Surface Preparation for Waterproofing Systems
PRIMER PU-1000 is a single-component, low-viscosity polyurethane resin designed to enhance bonding and improve surface leveling before applying DESMOPOL or TECNOCOAT liquid waterproofing systems. With a high solids content, this primer ensures strong adhesion on porous substrates like concrete and mortar, making it an essential preparatory layer for effective and long-lasting waterproofing.
Key Features:
✔ Superior Adhesion – Achieves >2 N/mm² (MPa) bond strength on concrete.
✔ Optimized for Porous Substrates – Ideal for concrete, cement, and mortar surfaces.
✔ Versatile Application – Suitable for bonding waterproofing membranes' repairs and overlaps.
✔ Fast Tack-Free Time – Dries in ±60 minutes at 23°C, allowing efficient application.
✔ Translucent Finish – Ensures minimal visual impact on substrates.
✔ High Solids Content – Improves durability and bonding strength.
✔ Can Be Used with Mineral Particles – Enhances adhesion on uneven surfaces when mixed with silica sand.
Ideal Applications:
-
Priming porous substrates before applying DESMOPOL or TECNOCOAT membranes.
-
Bonding for waterproofing membrane repairs and overlap work.
-
Leveling and sealing concrete or cement surfaces before liquid membrane application.
Application Guidelines:
-
Surface Preparation: Ensure the surface is flat, clean, dry, and as hard as possible.
-
Application Methods: Can be applied using roller, brush, or airless spray equipment.
-
Surface Humidity Tolerance: Maximum 5% surface humidity. Do not apply on damp or water-exuding surfaces (e.g., condensation, leaks, phreatic level pressure).
-
Dilution: Up to 5% with DESMOSOLVENT for low-absorption surfaces.
-
Coverage: 25-30m² per application (varies depending on substrate condition).
-
Recommended Application Thickness: 150-300 g/m² in one or several thin layers (avoid thick coats).
