WRX Trade XPrime is a water-based, ready-to-use acrylic adhesion primer for hard-to-paint surfaces, suitable for interior and exterior use. It grips to old paints and varnish, metal (including galvanised), rigid PVC, glass, ceramic, wood, brick and plaster, and can be over-coated with any architectural water- or solvent-based paint; EN 71-3 compliant for toy and furniture renovation.
WRX Trade XPrime is a problem-solving, water-based acrylic adhesion primer engineered to grip difficult, mixed or previously coated substrates. It bonds to old paints and varnish as well as iron, steel, aluminium, copper, zinc, galvanised steel, rigid PVC, glass, ceramic, wood, brick and plaster, creating a uniform, paint-ready surface.
It can be applied over areas previously finished with solvent-based paints and used as a bridging coat, after which you can over-coat with any architectural water- or solvent-based topcoat. The formula also locks in many common stains (such as graffiti, asphalt, grease, lipstick and smoke) and traps tannins from cedar and redwood to help prevent bleed-through. Suitable for both interior and exterior projects, XPrime streamlines preparation when your job spans multiple surface types.
Ensure surfaces are sound, clean, suitably dry and free from contaminants that impair adhesion; remove loose/flaking material and repair defects.
Metals: remove oil and rust.
Wood: sand with the grain; remove dust and any seeping resin; treat bare wood with a wood preserver.
Plastics: lightly sand and clean thoroughly.
Do not use on anodised aluminium.

Do not apply in damp/humid conditions or below +8 °C.
Stir well. Product is ready to use; if needed, thin up to 10% with clean water (over-thinning may impair adhesion).
Apply by brush, medium-pile roller or spray. Load the brush generously, apply evenly, avoid over-spreading.
In most cases one coat is sufficient; porous areas or some stains may need a second coat.
Up to 12 m² per litre per coat, depending on surface smoothness and absorbency.
Touch dry: ~30 minutes
Recoat: 4 hours
Top coat: 6 h (water-based) / 12 h (solvent-based)
