Another Best Outdoor Oil finish thread question.....

[Earthling#44-9a]

Gday:)
Ive done a few searches, however not much info comes up...lots of people asking but not many answers.:doh:

I do a bit of sculpture when the inclination grabs my loins, however I have yet to find a good long lasting outdoor oil finish to apply. Reading some posts, people were mixing varnish in with finishing oil and turps to make a mixture worthy of their wood. I wasnt too sure about that one.

Any one back the last claim up or do you know of an oil finish/mix that works best? :?

I prefer matt/satin finishes.

Cant back up any claims, sorry.

But I like natural oil finishes like organoil or tung oil, They bring out the colour of the wood, protect it and imo look good.

Plus you can touch it up easily with some oil on a rag now and then.

Yeah I have used organoil, definet favourite for indoor, however I find outdoor it needs reapplying waaaaaaay toooo often.
Havent used tung oil before, does it last longer then organoil?

Turps or other suitable thinner. Can use less or more thinner to choice as it's purpose is to help finish penetrate wood
Varnish of choice
Oil. Either boiled linseed oil or tung oil

Mixture two recipe
Mix two handfuls of shredded beeswax to equal parts of boiled linseed oil and raw tung oil. Heat the mixture carefully . (This part can be a problem. I have made beeswax polish without heat using natural turpentine) However I feel a bought wax might be safer.

Application

Apply three or four coats of mixture one. Let oil sit on surface for 5-10 minutes. Or you can sand the mixture into wood using 400-600 wet and dry. Remove excess oil with clean cloth/paper towel. Allow at least twenty four hours drying time between each coat. Apply two to three coats of mixture two. Rub each coat into surface very vigorously.

How would this method go for outdoor use? I imagine it would last longer then a straight outdoor decking oil finish correct?
If you just do stage one (turps, varnish, oil mix) is 4 or 5 coats of that adequate, as the beeswax and tungoil isnt going to penetrate the wood much, if at all, after the previous mixture sealing the wood? I imagine its more for sheen, yes? Thoughts?

No oil is going to give you a lasting finish outside. 6-12 months (maybe 18 depending on your standards) will be about it, if you want longer than that between refinishing you will need to look at varnish.

A good marine varnish will give you 3-5 years between recoats, but you'll need to scuff sand (or more) when you do the recoat rather than just slop more on like you can with oil; however satin finishes don't seem to be as durable as full gloss.

Using a proper epoxy adhesive under the varnish (as a sort of soak-in pre varnish coating) can help increase the lifespan of the varnish as well as make it a bit easier to re-finish. (haven't looked at this long-term. Check the boatbuilding threads for more)

I'd stick with the oil, just make it part of the spring or autumn tidy up.
