Topic tags/keywords: question finishing oil danish oil blo poly mineral spirits homemade recipe

Finishing Gurus,

Since I first started woodworking I’ve always been intrigued by the idea of “homemade” finishes. Last night I finally made my own “danish oil” by adding 1/3 poly, 1/3 BLO, and 1/3 mineral spirits. I put it on a few test pieces and so far it seems to work great. However, I have no idea what kind of shelf life it will have. I put it in an old spaghetti sauce jar with white plumber’s tape on the threads to make sure it’s air tight.

How long can I expect it to last?

Also, this got me wondering what other type of “homemade” finishes are out there. I really like oil finishes like danish oil or BLO, is there any other combinations that work well? I remember seeing something once about beeswax and oil but I can’t remember where I saw it.

Any of you finishing experts out there have some recipes you’d like to share?

Thanks.

-- David

I would write the date you made it on the jar. Thats all I can suggest. I think the teflon tape is a great idea.

David, I have found that, once it is diluted with mineral spirits, poly mixtures tend to last much longer than concentrates. I have had poly skim over within a few months of opening the can. I toss the finish once this happens. Whereas I have kept poly/blo/mineral spirits mixes well in excess of two years without doing anything other than making sure the lid is on tight. I generally make them up one gallon at a time and run with this until I need to mix some more.

Thnx for your input Scott. It’s nice to hear it lasts for that amount of time. Appreciate you having an answer for David, and myself.

Yes, thanks for the info Scott. I had no idea it’d last that long, that’s good to know so I can mix up bigger quantities at once.

Hi David, I had a play about and did some trialing some years ago and found the following all work very well.
DANISH: Try thinning with about 20% meths & use it as a undercoat, an overcoat of Teak will generally give you a good hard polish finish.

“HUNGRY” WOOD: A good sealer for real hungry timber is equal patrs of, Poly, Raw linseed oil, Tung il & Vegetable (gum) turps (not mineral) dont use this on food items or under spirit based finishes shellac etc

WAX: If you want to have a go at your own wax then mix up equal parts of beeswax and vegetable turps, make sure you keep it in an airtight jar.
Sealer, I generally use a mix of mineral turps & poly as universal sealer, theproportions to suit the timber; hard timber a little thinner soft a little thicker, anywhere between 30% to 70% poly
look forward to seeing other peoples recipies, this is a fasinating topic

Any sort of oil-based varnish mixed 1:1 with mineral spirits makes a wiping varnish. I like Behlen’s Rock Hard Tabletop varnish, it has a nice deep color to it. And thinning it does make it last longer before it skins over.
