Prime the Surface

Use ARDEX WPM 300 as a water-based epoxy moisture barrier and primer for damp or green concrete, resisting 250kPa hydrostatic pressure. It ensures less than 10g/m²/24hrs moisture vapour transmission and is compliant with AS/NZS4020 for potable water.

Use ARDEX Multiprime for priming porous concrete, render, and AAC to improve adhesion for ARDEX systems. It dries in 15-30 minutes and offers reliable bond strength for demanding applications, avoiding issues caused by untreated substrates.

Use Gripset GP Primer for enhancing adhesion of Gripset membranes and tile adhesives on porous substrates. It dries in 30 minutes, covers 8-10m² per litre, and is crucial for preventing callbacks due to poor bonding.

Use Gripset OP Primer for reliable adhesion on challenging non-porous surfaces like metal, existing tiles, and PVC. This solvent-free, low VOC primer delivers a textured finish and dries in 30 minutes, ensuring a strong bond for Gripset membranes and tile adhesives.

Use RLA Universal Primer to manage suction on porous concrete or promote adhesion on non-porous surfaces like tiles. This water-based acrylic primer dries tack-free in 30-60 minutes, preventing bond failures before tiling or levelling.

Use Mapei Primer G for critical substrate preparation, ensuring stable adhesion and preventing common failures like ettringite formation between gypsum and cement-based materials. It offers EC1 Plus low VOC emissions and fast drying.

Solvent-free acrylic primer with excellent adhesion, flexibility, and water resistance. Suitable for concrete, ceramic, wood, and other internal flooring substrates.
