BAL Prime APD is a rapid-drying acrylic primer suitable for priming wall and floor backgrounds prior to the fixing of ceramics, mosiacs and natural stone tiles in dry or wet interior and exterior environments. BAL Prime APD stabalises dusty surfaces and reduces the porosity of backgrounds and may be used undiluted on plaster walls and plasterboard, tongue and groove floorboards and anhydrite screed floors. Use diluted on plaster walls (if dusty or porous) and cement floors.

As a rapid-drying primer, BAL Prime APD produces cost and time savings for your project, stabiling backgrounds in ultra-quick time allowing for tiling with a suitable adhesive in 15-30 minutes. BAL Prime APD is suitable for a variety of projects including walls and floors, worktops, showers, heated screeds and areas with limited movement or vibration. Typical coverage of BAL Prime APD is 5-10m2 per litre undiluted, 10-20m2 per litre diluted 1:1 with water.

The BAL Prime APD Primer minimises the risk of reaction between the two materials and provides surface strength to friable surfaces. It reduces porosity - preventing air bubbles and prolonging the flow time of levelling compounds and extending the open time of tile adhesives.
