Flushes: When moisture builds up in your material drum, hoses, or equipment - it can cause harmful crystals to form. Items like Desiccant Dryers help to safely remove moisture, preventing crystal buildup. While products like the Power Flush System and Dynalube can help to break up crystal and residue formation, while cleaning and lubricating your spray gun. Lubricants: Just like any piece of machinery, your guns and parts should be regularly lubricated and greased. Overspray Release has a bi-fold purpose, lubricating parts and guns serves one of those purposes. Releases: Spray foam can be a double edged sword by causing material buildup on your respirator mask, making it difficult to spray for long periods without having to clean your mask or replace a protective sticker. Overspray Release, when applied to your mask and spray gun, make cleaning easy with just a quick wipe.
