General Application Steps

For use as a joint coating, a refurbishing coating or as a pipe coating:
1. Remove oil, grease and loosely adhering deposits.

  1. Abrasive blast clean the surface to NACE No. 2/SSPC- SP10, ISO 8501:1, Grade SA 2 1/2 near-white metal.
  2. Ensure the abraded surface is cleaned of abrading debris with the use of an air blast or a clean lint free cloth then verify anchor profile is 1.5 – 4 mils.
  3. Within four hours of blasting as per the above cleaning process and with the metal above 41 ̊F/5 ̊C and a minimum of 5°F/3 ̊C above the dew point, apply Scotchkote 323 at recommended film thickness. Allow to cure.
  4. Repair all defects using Scotchkote 323.

For use as a repair material in the field where scratches or other holidays may have occurred.

  1. Remove oil, grease and loosely adhering deposits.
  2. Abrade the FBE surface with medium grit sandpaper (approx 80 grit). Powered rotary sanders and sweep blasting are also acceptable means of performing this task as well. Ensure that the surrounding FBE is roughened for 10 mm on all sides of the holiday.
  3. Ensure the abraded surface is cleaned of abrading debris with the use of an air blast or a clean lint free cloth then verify anchor profile is 1.5 – 4 mils.
  4. With the metal above 41 ̊F/5 ̊C and a minimum of 5°F/3 ̊C above the dew point, apply Scotchkote 323 at recommended film thickness.
