    How do I clean Up DAP® 3.0™ High Performance Sealant?

    Excess uncured DAP® 3.0™ High Performance Sealants can be cleaned up from surfaces or tools using mineral spirits. Once they have cured, any excess sealant needs to be cut or scraped away.

    If I only use half of a cartridge, can I use the other half at a later date? If so, what are the proper storage conditions?

    Yes. You can use the remaining product after the cartridge is opened if stored properly. The cartridge should be stored below 80°F in a dry place. When ready to use again, remove the cured material at the tip or cut the tip back to reveal fresh product.
