Preparation

  • Mixing ratio: 4:1, Base: Activator by volume. Ideally the full 500g unit should be mixed.

  • Stir contents of each tin thoroughly before mixing required amounts vigorously together, to produce an evenly coloured compound. Keep unwanted component resins separate until needed to ensure indefinite shelf life.

  • In cold weather conditions, the product may appear to have solidified. This is due to the crystallisation of resins. Heating on a radiator, in hot water etc, will bring product back to perfect condition. Allow to cool again before mixing.

Working method

  • Apply with a knife or spatula, within 30 minutes of mixing.

  • Machine, drill, tap or file, as with pure metal, once product has cured.

  • Ensure surfaces are clean and free of all loose contaminants, especially oil or grease.

  • On difficult surfaces (eg. aluminium, glass) score by scratching or drilling to increase surface area and improve key.

  • Use of All Purpose Cleaner is recommended for cleaning surfaces and utensils.

  • When repairing cracked metal (eg. engine block) limit extent of crack by drilling at each end. Drill out or “vee” out crack to increase volume to be filled.

  • If part of a surface being repaired should be kept free of resin, treat with Release Agent beforehand.
