Description
Ardex P51 Primer 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. It is used to prepare 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.
Ardex P51 Primer is used as am 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 P51 Primer 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.
Ardex P51 Primer can be used as a bonding agent to improve adhesion to dense and smooth concrete sub-floors and dense cement based screeds before using repair mortars or cement-based tile adhesives. It is suitable for priming rigidly supported and conditioned plywood sub-floors before fixing ceramic tiling with appropriate cement-based tile adhesives.
Ardex P51 Primer can also be used as a temporary protective coating over cement-based smoothing compounds and repair mortars where these have to be walked on before the flooring is applied and as a temporary dust-proofing treatment on screeds.
Ardex P51 Primer is not recommended for use on metal and mastic asphalt, excess adhesive residues, Ardex DPM, polyurethane and epoxy coatings. Consult the Ardex P82 Water Dispersed Epoxy Primer and Ardex R3E General Purpose Epoxy Primer datasheets for guidance.
