Porous Substrate Primers

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 Primer WBP for preparing porous concrete and screeds for Adheseal water-based membranes. It beds down dust and ensures strong adhesion, meeting Green Star criteria with very low VOCs.

Use Everflex Supaprime to ensure robust adhesion for Adheseal sealants and membranes on porous substrates like concrete and timber. Its rapid cure and deep penetration prevent costly delamination, providing a reliable bond for critical applications.

Use Sika Primer-3 N to enhance adhesion for specific Sika sealants and adhesives on porous substrates and metals. Its solvent-based epoxy resin formula is water repellent and offers a short 30-minute flash-off time, ensuring robust system performance.

Use SILCOR Primer BS for reliable adhesion of SILCOR polyurethane membranes to most rigid construction substrates. Its fast-drying (30-60 min) modified polyurethane resin ensures a strong bond and water resistance, critical for weather-interrupted jobs.

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 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.
