ARDEX P 51 is a multi-purpose primer ideal for priming porous surfaces prior to the application of ARDEX water-based levelling and smoothing compounds.

A concentrated, blue, synthetic, water-based, solvent- free multi-purpose primer with a wide range of applications which, after drying, helps to inhibit the penetration of water from subsequently applied materials.

• Multipurpose – seals and primes a wide range of applications
• Blue pigment allows clear identification of primed areas
• Convenient re-sealable tub
• Provides up to 160m² coverage per 5kg unit
• Easy to use, dilute as appropriate for the application
