Ardex P51 Primer - Concentrated Water-Based Primer & Bonding Agent - 1kg & 5kg

Ardex P51 Primer is a concentrated, blue synthetic, water-based, solvent-free primer used to prepare internal surfaces to receive cement-based levelling compounds, adhesives, screeds, and plaster-based materials. It helps improve adhesion and works to inhibit penetration of water in intermittently damp locations. P51 can be used to prime porous surfaces prior to the application of ARDEX water-based levelling and smoothing compounds, and wood based sheets and boards prior to the application of ARDEX X 7001 tile adhesive.

Only use as the primer on floors that are dry and have an effective damp proof membrane.

Key features and benefits include:

• Multipurpose: Suitable for a wide range of applications
• Easy to use: Dilute as appropriate for the particular application
• Ideal for sealing and priming gypsum based plasters and screeds including: wall plaster, cement-based screeds, and anhydrite screeds
• Minimises air bubbles rising through levelling compounds and porous surfaces
• Low odour and solvent free
• Cost-effective, up to 160m²/5kg unit
• Blue pigment allows clear identification of primed areas
• Convenient re-sealable tub

Note: Ardex P51 Primer is NOT recommended for use on metal and mastic asphalt, excess residues, polyurethane, and epoxy coatings. For these, use Ardex P82 Water Dispersed Epoxy Primer.
