Introducing BAL Prime APD, a rapid-drying acrylic primer designed for priming wall and floor backgrounds before the installation of ceramics, mosaics, and natural stone tiles. This versatile primer is suitable for both dry and wet interior and exterior environments. BAL Prime APD stabilizes dusty surfaces, reduces porosity, and provides surface strength to friable surfaces.

Here are some key features of BAL Prime APD:

  • Stabilizes dusty surfaces and reduces porosity of backgrounds.
  • Can be used undiluted on plaster walls, plasterboard, tongue and groove floorboards, and anhydrite screed floors.
  • Can be used diluted on dusty or porous plaster walls and cement floors.
  • Rapid-drying formula allows tiling with a suitable adhesive in 15-30 minutes.
  • Provides surface strength to friable surfaces.
  • Reduces porosity, preventing air bubbles and prolonging the flow time of levelling compounds.
  • Extends the open time of tile adhesives.
