Surface Preparation

Surfaces must first be clean, dry and free of dirt, grease, grime, all loose material and other contamination. Remove all rust from around the area to be repaired back to bright clean metal. Remove all loose and old finishes from around the area to be repaired. Thoroughly abrade the surface using a file or coarse abrasive paper. Wipe the surface clean with Acetone, Ethyl Acetate, Methylated Spirits (De-natured Alcohol) or similar to remove any abrasion residue. DO NOT use White Spirit.

Applying Cosmofer 2-pack universal polyester filler

Mixing

Add 2% of the hardener to quantity of filler for 10 minutes drying. As a guide 1 coffee bean size of hardener to 1 chestnut size of filler. In cold weather increase amount of hardener. In hot weather decrease amount of hardener. Ensure the hardener and filler are well mixed. Increasing or decreasing the amount of hardener does not affect the overall curing time.

Applying Cosmofer

Work the filler in to the crack, hole or dent and smooth off with a filling knife. For repairs deeper than 50 mm – build up in layers allowing it to dry between applications. For a smooth finish sand (100 grit paper) before applying your finish. Allow 24 hrs after application before machining (drilling, mechanically sanding, tapping…).

Clean Up

Clean tools immediately after use with Acetone, Ethyl Acetate or similar. Dispose of any unused hardener/filler mixture in accordance with local regulations. DO NOT put it back in the container.

Things to Remember

  • For narrow cracks rake out to enlarge
  • Stir filler well before mixing with hardener
  • Do not mix filler and hardener in the can
  • Apply between 10°C and 25°C
