I have doors, patio furniture and windows which all need constant attention in terms of varnish and wood sealers.

I have recently found a good contact for raw linseed oil, and would like to use something like this to preserve my wood.

What is the better choice between raw and boiled linseed and should I rather use the polywax sealers that you get in stores?

Essentially I would like to retain the lustre of the wood.

I've never used linsoid oil on any of my outdoor projects, so I am looking forward to seeing if anybody has an answer. – RyanWinchester Feb 17 '13 at 22:38
From the resources on the internet, it says that linseed (flax oil), has excellent sealing properties, applying it to my wood really makes it look good and healthy, the only negatives i can see are that the coat needs to be re-applied quite frequently, and that the boiled oil can become sticky after a few coats. – Hightower Feb 20 '13 at 7:06
And store any rags/applicators in an airtight fireproof container. The oxidation/polymerization that lindseed oil undergoes is exothermic and can set things on fire. A thin layer on a rake handle ok. A thin layer on multiple layers of fabric wadded together = disaster. – Fiasco Labs Aug 18 '13 at 22:13

I've used linseed oil on deck furniture. It gave a beautiful finish (brought out all the natural colors), and looked great for the whole summer. But by the next year it needed doing again, which I'll be doing soon. It's cheap deck furniture, so I don't mind if it degrades a little while I pretend it doesn't yet need to be retreated. Personally, I wouldn't do that with window/door trim.

IIRC, I mixed it with turpentine, which I believe helps it soak into the wood.

Elsewhere on my house I'm testing a toner product called Penofin, on some redwood. That's holding up great so far, and I'm expecting to only have to re-apply it every few years. (it contains micro metalic elements, which reflect/block some of the harmful UV light) There are plenty of Penofin competitors / alternatives too. Personally, I'd use something like that on doors/windows, or paint them.

We used linseed oil on an outside door. Big mistake as it promoted mould as the doors got the sprinkler spray. Better to use one of the commercial outdoor furniture oil as it is non-organic.

I have always used boiled linseed oil on the handle of my garden equipment. Wooden shovels, rakes, pickaxes, and such. That's what I thought it was for. It lasts a long time and doesn't get slick or gummy. I just get a rag wet with it and wipe it on. It should look great on some outside furniture.

We built our log cabin about 10 years from recycled logs. We wanted to protect our logs from rot, boring beetles, and carpenter ants. Originally we made a trough and soaked our logs in boiled linseed oil and kerosene, like they did in the days of yore. It is much less expensive than polyurethane and paint thinner. Linseed oil is thick so it must be thinned out to enter the pores. We are extremely satisfied with the results, especially since log homes are high maintenance. If you are considering building a log cabin from scratch. Talk yourself out of it and stick build it! Ha ha, and good luck

We use it on actual tow behind trailer decks, it needs done once a year but prolongs the life of the treated wood that's on there.

This doesn't answer the question. – Tester101 Jun 16 '15 at 12:00
