Description ARDEX P4 Multi-Purpose Grip Primer is a ready-mixed, rapid-drying, multi-purpose, drip-free, solvent-free primer with added grit particles that leave a textured grip finish. ARDEX P4 Multi-Purpose Grip Primer can be used on internal and external walls, ceilings, and floors. The consistency of ARDEX P4 Multi-Purpose Grip Primer 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 Multi-Purpose Grip 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, porches, etc. If a damp proof membrane is required consult the ARDEX DPM 1 C datasheet. ARDEX P4 Multi-Purpose Grip 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 Surface Preparation: Surfaces should be firm, sound, and free from dust, dirt, water-soluble materials, excess adhesive residues, and other barriers to adhesion. Polish, wax, grease, etc., should be removed using a degreaser prior to suitable mechanical preparation. Where ARDEX P4 Multi-Purpose Grip Primer will be used in conjunction with moisture-sensitive materials, the substrate must be dry, i.e., have a Relative Humidity of no greater than 75% and where appropriate, be protected by a functioning ARDEX damp proof membrane such as ARDEX DPM 1C. Apply ARDEX P4 Multi-Purpose Grip Primer to a cured ARDEX DPM 1 C within 36 hours and to ARDEX DPM 1 C R within 8 hours. ARDEX P4 Multi-Purpose Grip Primer can be used under ARDEX smoothing and levelling compounds on internal concrete. It is ideal for use externally under ARDEX K 301 Exterior Self-Smoothing and Resurfacing Compound. Application: ARDEX P4 Multi-Purpose Grip Primer is a ready-mixed and ready-to-use primer. Apply a thin, even coat with a short pile roller or paintbrush. Apply the primer evenly and allow sufficient coverage on the substrate so that once dry it will give an opaque white film. This should not be a translucent or transparent film. Before applying tiling or flooring products, leave to dry to form a thin, even white film. The drying time depends on the temperature and absorbency of the substrate, typically 30-60 minutes at 20°C. On certain substrates in favourable conditions, this can be as little as 30 minutes. High temperatures and absorbent substrates will shorten the drying time. At lower temperatures and on dense substrates, the drying time will be extended. Once dry, there is no time limit on how long before subsequent compounds or products must be applied, but we recommend this is done as promptly as possible to avoid surface contamination or damage to the primed floor. Reseal opened packaging after use to avoid evaporation and contamination. To facilitate application onto absorbent substrates, ARDEX P4 Multi-Purpose Grip Primer may be diluted with up to 1/4 litre of water per 2kg tub or 1 litre of water per 8kg tub. Use on surfaces where the temperature is at least 5°C and rising. Note: ARDEX P4 Multi-Purpose Grip 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 P 51 or ARDEX P 82 technical datasheet for advice. Packaging: ARDEX P4 Multi-Purpose Grip Primer is available in an 8kg tub. Coverage: An 8kg tub of undiluted ARDEX P4 Multi-Purpose Grip Primer should cover at least 40m² on most typical substrates. Coverage should not exceed 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.
