Application steps

SUBSTRATE PREPARATION

  • All concrete surfaces must be clean and free from any loosely adhering particles or contaminants such as dirt, oil, dust, grease, etc.
  • All cement laitance should be removed by scabbling, sandblasting, etc.
  • Steel surfaces must have all paints, films, oils, rust and other contaminants removed by grit blasting. Apply Sikadur® UA immediately after blasting is completed.
  • Cementitious substrates should be pre-wetted to a saturated surface dry (SSD) condition just prior to application.

MIXING

  • Mix equal proportions of resin (Part A) and hardener (Part B) on a clean board with a spatula or steel trowel. Mix thoroughly until an even streak free grey colour is achieved. Sikadur® UA can also be mixed together by ‘kneading’ with gloved hands (keep gloves wet to prevent epoxy sticking during 'kneading').
  • Mix ratio of resin (Part A) : hardener (Part B) = 1 : 1 (by weight or volume).

CLEANING OF TOOLS

Clean all tools and equipment immediately after use with fresh water. It is recommended that protective gloves and clothing be worn during application, however, uncured Sikadur® UA may be removed from skin with warm soapy water. Cured Sikadur® UA can only be removed mechanically.
