Qty:

ARDEX P 51 is 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.

Features:

  • Multipurpose – Suitable for a wide range of applications
  • Easy to use, dilute as appropriate for the application
  • For floors, walls and ceilings, including dense and porous surfaces
  • Ideal for sealing and priming gypsum based plasters and screeds
  • Minimises air bubbles rising through levelling compounds and porous surfaces
  • Low odour and solvent free
  • Cost effective, up to 160m²/5kg unit

Uses:

This product is used to prepare dry internal floors, walls and ceilings to receive cement-based mortars (levelling compounds, tile adhesives, screeds) as well as plaster based materials, improving adhesion as a bonding agent and retarding the wetting of the substrate by the applied materials.

Effective pore sealer on absorbent sub-floors inhibiting air bubbles rising through subsequently applied sub-floor smoothing and levelling compounds, thus extending their flow life and workability.

ARDEX P 51 can be used to prime and seal the surfaces of cement or gypsum plaster based materials such as wall plaster, floors of cement based or prepared anhydrite and alpha hemihydrate pumped screeds before applying cement-based products such as levelling compounds and tile adhesives.

Substrate Dilution
Smooth and non-porous substrates, e.g. prefabricated concrete floors, dense cement screeds, improved calcium sulphate screeds, terrazzo, sandstone, ceramic tile and slab type finishes. (Dependent of the information from the gypsum screed manufacturer, a suitably sand blinded coat of an epoxy primer such as ARDEX R 3 E Moisture Tolerant Epoxy Primer, may be required).

Rough concrete sub-floors and ceilings. 1 part ARDEX P 51 with 1 part water.
Power Float Concrete. 1 part ARDEX P 51 with 2 parts water.
