To know before applying

  • Concrete, Cement-Sand Render / Screed & Masonry surface must be fully cured, dry, sound, flat or true & free of contaminants eg. grease, oil, dust, loose particles, laitance etc.
  • Steel / Metal surface must be free of scales, rust, grease, oil etc.
  • Damp the surface before coating and sweep the excess water to avoid ponding on the horizontal area. This is particularly important if substrate exhibits a high degree of water suction. Rapid loss of moisture from the waterproof coating may result in pinholes, poor adhesion and overall weakened properties.
