What are indicators that my two-part polysulfide may not be thoroughly mixed?

  1. Application period is a lot shorter than indicated: If you are using a machine mixer or a hand drill, you may be operating it at too high of a speed which can create internal heat and shorten your application time.
  2. You see streaks of color in the cartridge or container. (Learn more about the rule of thirds for kit mixing!)
  3. It’s not fully curing.
  4. It’s not adhering properly to the surface once cured.
