  • Finish preserver reduces waste, saves time and money
  • Easy to use
  • Ultra-pure argon gas is 100% natural
  • Contains no added propellants, VOCs or CFCs

Bloxygen Finish Preserver forms a protective layer of heavy, inert argon gas in the top of the can. It displaces oxygen and moisture, preserving leftover paints and varnishes and protecting them during storage. Use this finish preserver to extend the shelf life of leftover oil-based paints, oil-based stains, varnishes, polyurethanes, paste wood fillers, glues and resins.

Easy to use – just leave a small opening between the lid and the paint can, insert the extension tube into it, spray the recommended amount of short bursts depending on can size, then seal the container immediately.

Here are some of the oxygen or moisture sensitive products you can preserve, but there are many more!

  • varnish
  • oil-based paint
  • epoxy resin
  • wood fillers
  • polyurethanes
  • marine coatings
  • catalysts
  • urethanes
  • stains

NOTE: Bloxygen will not preserve finish products that don’t cure via oxygen absorption, such as water-based finishes or lacquer.
