Application steps

SUBSTRATE PREPARATION

  1. Fully expose any corroded steel in the repair area. Remove all loose scale and corrosion deposits, paying particular attention to the back of exposed steel bars.
  2. Mechanically abrade all exposed steel to remove corrosion from pits and imperfections within its surface.

APPLICATION

  1. Thoroughly stir Sikagard® P 8100 AP prior to use.
  2. Apply Sikagard® P 8100 AP to a dry surface as soon as possible after completion of the preparation work, but always within 3 hours. Apply one continuous coat with suitable brush, making sure the back of the exposed steel reinforcing bars are completely coated.
  3. Two coats of 4 mils WFT are required to ensure complete coverage of the surface. Allow the first coat to fully dry before applying the second.
  4. Concrete-repair materials can be applied as soon as the Sikagard® P 8100 AP is fully dry. Do not leave the primed surfaces exposed to the elements for longer than 7 days before recoating or applying repair materials.

CLEANING OF TOOLS

Clean hands and skin immediately with soap and water or industrial hand cleaner. Remove Sikagard® P 8100 AP from tools, equipment, and mixers with xylene immediately after use
