  • Ideal as a pre-treatment for renderings required to resist severe exposure conditions
  • Equalises suction on mixed backgrounds
  • Provides excellent suction control across both high and low suction substrates
  • Resists the penetration of external water to improve the weather resistance of rendering systems
  • Quality controlled and factory blended to give a consistently high quality product
  • Apply with a hawk and trowel or an open hopper spray gun, apply a tight layer 2 - 3 mm thick to the substrate. Texture the surface using a well loaded roller
  • Suitable substrates: dense concrete brickwork blockwork masonry clean, sound, well adhered existing render (<19mm)
