ARDEX P 51 is used to prepare internal surfaces to receive cement-based levelling compounds, adhesives, screeds, as well as plaster-based materials, improving adhesion and inhibiting penetration of water in intermittently damp locations. It is used as a pore sealer on floor surfaces to prevent air bubbles rising through subsequently applied sub-floor smoothing and levelling compounds and to prolong their flow life and workability. Only for use as a primer on floors that are dry and have an effective damp proof membrane.

ARDEX P 51 can be diluted with an equal volume of water to prepare a grouting slurry for bonded screeds, when mixed with ARDEX A 23 or A 35 Screeds.
