  2. Clean. Brush or wipe away any dust that results from the sanding and dry the area you’re working with.

  4. Mix. Mix the resin and hardener together for the length of time specified on the product’s instructions.

  4. Apply. As soon as the epoxy putty is mixed, apply it to the chip until the hole is filled. Use a profiling or smoothing tool to ensure the surface of the putty is flush with the rest of the sink. 
  5. Sand. If you’ve made any mistakes and the dried putty isn’t completely flush with the rest of the sink, use a fine sandpaper to sand it down until you’re satisfied. UniBond Repair Express Power Putty can be sanded after five minutes of it being applied.
  6. Dry. Leave the putty to dry and do not use the sink for 24 hours.
