Application steps

SUBSTRATE PREPARATION

  • New concrete, screed or render should have a brushed or wood float finish, and should be free from contamination by any material that could impair adhesion. All surface defects should be repaired by approved methods. Protrusions greater than 3 mm should be removed.
  • Existing concrete, screed or render should be well prepared to provide a dense, defect free substrate.
  • Concrete surfaces should be mat-moist and free from standing water.
  • Brickwork, blockwork and masonry should be flush pointed.
  • All intersections of horizontal and vertical surfaces should be profiled with a mortar fillet of 25 x 25 mm.

MIXING

Mechanical mixing is not required. Product should be manually stirred with a plastic spatula until a smooth consistency is obtained.

CLEANING OF TOOLS

Clean all tools and application equipment with water immediately after use. Hardened or cured material can only be removed mechanically.
