How to use the USC Half Time Glazing Putty

  • Surface Preparation: Clean the surface by removing oil, dirt and grease. You can use a cleaning solvent. Dry the surface and ensure there is no moisture on it before you begin the repair job.
  • Mixing: Mix putty with the included hardener at room temperature using a plastic mixing board. Mix them on a clean surface in the ratio of 50:1 (putty and hardener). Use a plastic spreader to mix them thoroughly with a folding action.
  • Application: Use a plastic spreader to apply a thin layer of filler to the surface. You need to use firm pressure for absolute adhesion. Apply additional layers to build up damaged area higher than the surface that surrounds. This will give you room for sanding the putty as required. Do not use this mixture over fresh uncured coatings.
  • Finishing: Leave the material to harden for 15 minutes and then you can sand it with 100-180 grit sandpaper. Follow it up with 220-400 grit sandpaper if necessary.
  • Top coating: You can use polyester, 2K urethane or 1K primer for a topcoat over the repaired surface.
