Description
Ardex P4 Primer is a ready mixed, rapid drying, multi-purpose, drip free solvent free primer.
Ardex P4 Primer can be used on internal and external walls, ceilings and floors. The consistency has been optimised so that dripping and splashes are virtually eliminated.
For use prior to the installation of Ardex tile adhesives and floor-levelling compounds. Ardex P4 Primer produces a textured grip which facilitates tile on tile application, eliminating the risk of adhesives slipping when being applied to smooth surfaces.
It is the ideal primer for use in areas which may become damp or wet such as kitchens bathrooms and porches, etc. If a damp proof membrane is required consult the Ardex DPM 1 C datasheet.
Ardex P4 Primer is suitable for use on substrates such as:
• Concrete
• Cement and lime renders
• Sand/cement screeds
• Ceramic Tiles and slabs
• Terrazzo
• Dispersion based paints
• Traces of non-water soluble, flooring adhesives
• Dry screeds
• Levelling and smoothing compounds
• Ardex Damp Proof Membranes
Apply Ardex P4 Primer to a cured Ardex DPM 1 C within 36 hours and to Ardex DPM 1 C R within 8 hours.
Ardex P4 Primer can be used under Ardex smoothing and levelling compounds on internal concrete. Ardex P4 is ideal for use externally under Ardex K 301 Exterior Self-Smoothing and Resurfacing Compound.
To facilitate application onto absorbent substrates, Ardex P4 Primer may be diluted with up to 1/4 litre of water per 2kg tub or 1 litre of water per 8kg tub. Use surfaces where the temperature is at least 5°C and rising.
NOTE: Ardex P4 Primer is not recommended for submerged locations such as swimming pools or substrates such as metal, mastic asphalt, excess adhesive residues, Polyurethane and Epoxy coatings. For wood or wood based substrates please consult the Ardex P51 or Ardex P82 technical datasheet for advice.
Packaging:
Available in a 2kg and 8kg tub.
Coverage:
A 2kg tub of undiluted P4 Primer is usually sufficient for priming at least 10m² and an 8kg tub of undiluted P4 Primer should cover at least 40m² on most typical substrates.
Coverage should not exceed 12.5m² per 2kg tub and 50m² per 8kg tub. Coverage depends on the texture and absorbency of the substrate, for example smooth ceramic tiles will require less material than a porous surface such as a screed.
