Ardex PU 30 Primer & Sealer 11kg.

Key benefits include:

• One-component polyurethane primer and green sealer in one
• Use on internal and external porous and non-porous substrates
• Penetrates the surface of the substrate blocking capillary moisture up to 95% humidity
• Strengthening and consolidating the surface up to 2mm in depth
• Product Type: Two-component, polyurethane-based primer and sealer designed for use with Ardex systems and other floor preparation applications.
• Size: 11kg pack, offering enough coverage for medium to large-sized flooring projects.
• Colour: Clear or light amber, providing a consistent, professional finish once applied.
• Formulation:
  • Polyurethane-Based: Provides excellent adhesion, bonding, and sealing properties on a range of substrates, including concrete, cementitious surfaces, and existing floors.
  • High Durability: Designed to provide a long-lasting and resilient bond, preventing the failure of subsequent layers or coatings.
• Primary Uses:
  • Primer: Acts as a bonding primer for floor coverings, such as tiles, vinyl, and carpet, especially when applied over porous or absorbent substrates.
  • Sealer: Functions as a sealer to protect surfaces from moisture, dust, and other contaminants that may compromise adhesion.
  • Suitable for use on a variety of substrates, including concrete, cement-based surfaces, screeds, and old tiles (after proper cleaning).
• Application:
  • Underfloor Heating Systems: Ideal for use in conjunction with underfloor heating systems, providing a smooth, sealed base for flooring installation.
  • Concrete and Cementitious Substrates: Can be applied to newly poured or existing concrete floors and cement-based surfaces.
  • Moisture Barrier: Provides an effective barrier against moisture that may rise from below, preventing damage to flooring finishes, making it especially useful in areas prone to moisture or high humidity.
• Bonding Performance: Ensures a strong bond between the substrate and the top layers, increasing the longevity of floor coverings and the performance of other Ardex products like levelling compounds or adhesives.
• Drying Time: Typically dries to the touch within 1-2 hours, though full curing time may vary depending on temperature and humidity.
• Coverage: Approximately 8-10m² per 11kg kit, depending on the substrate’s porosity and the application method.
• Substrate Compatibility: Works well on a variety of substrates, including porous concrete, screeds, cement-based tiles, and more. Suitable for both interior and exterior applications when used as directed.
• Environmentally Friendly: Low VOC, making it suitable for indoor applications without compromising air quality or safety.
• Easy to Apply: The primer and sealer are easy to mix and apply with a roller or brush, allowing for smooth, even coverage across the surface.
