Ardex – P51 Concentrated Water-Based Primer & Bonding Agent
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.
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 P51 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 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. Suitable for priming rigidly supported and conditioned plywood sub-floors before fixing ceramic tiling with appropriate cement-based tile adhesives.
ARDEX P51 can 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.
Available in 1kg, 5kg and 25kg capacity.
ARDEX P51 Provides up to 160m² coverage per 5kg unit.
- 1kg container= 32m²
- 5kg container= 160m²
- 25kg container= 800m²
Shake the container well before use and dilute when required by putting the ARDEX P51 into a clean container and mixing with the required quantity of water as specified in the selected mixing ratio. Ensure that the ambient temperature and the temperature of the surface being primed are above 5°C.
If ARDEX P51 is used where moisture-sensitive materials are to be subsequently applied, the substrate must be dry, i.e. with flooring materials the screed should have an RH reading not greater than 75% and, where direct to ground, protected by an effective damp proof membrane.
Apply the priming coat evenly with a soft broom or brush, over the sound, clean and dust-free surface and leave to dry thoroughly to a clear, thin blue film before beginning any subsequent work.
Aqueous synthetic polymer-based dispersion. Wash off from the skin before drying takes place. Any material splashed into the eye, mouth or nose should be washed away immediately with clean water. Avoid ingestion. Non-toxic and small amounts are unlikely to cause more than temporary discomfort. If large amounts are swallowed seek medical advice.
Storage and Shelf Life:
ARDEX P51 must be stored in unopened packaging, clear of the ground; in cool, dry conditions and protected from excessive draught. If stored correctly, the shelf life of this product is 12 months from the date shown on the packaging.
