Bloxygen Gas for Preserving Unused Finishing Materials

Item #
86% of 100

Preserve unused finishing materials! Just spray in the can and seal. Bloxygen uses an inert gas to drive the oxygen out of your container. Simply blow the oxygen out of your container with Bloxygen and then seal the lid. The heavy, inert Bloxygen gas sinks down to block oxygen from the liquid surface. Because Bloxygen is heavier than air, it will separate the liquid surface from any air that may remain in the container, preventing a dry skin from forming over the liquid.

"Saves top coat from forming skin"
So far this works great but because it is just gas in a can, it will be hard to tell when the gas is used up.

Great stuff
I've been using Bloxygen since it first came out many years ago, when you had to order it from the original developer. It is truly a godsend when trying to preserve oil-based paints between uses. A skin eventually will form on top of the paint; but it takes a couple of years for such a skin to form--much, much longer than the usual couple of weeks.

It works
Many of my projects are toys. This allows for the finish to be used for small items and not finding a skin on the remailing finish in the can when reopened . In the past I would often need to trash a can that was still with some finish left.

Great for preserving Finishes
I use it to save and prolong the shelf life of Epifanes Varnish once I’ve opened a can. Marine Varnish isn’t cheap, so every little bit helps.

I have a wall full of paint, stain, and finishes in quart and gallon cans that will now have a long life. This stuff even works on spar var which will skim over in an open can in just a few minutes.

Cans of polyurethane, once opened, tend to cure up in the can wasting all that is left. This will keep oxygen away from the surface of the poly, keeping it from curing. I have used wine sprays which do the same thing, but are more expensive.
