I am in the process of building a step/landing area at the rear of my house out of white oak and am a little confused by the finish reading that I have done and thought I should just ask what I should be using for the most durable exterior finish that will take a beating. I am assuming that I don’t want to make an 1/3 blend of spirits, tongue and spar varnish since I would not get as much of a hard shell protection, or is this incorrect. I am also confused when I went to pick up some spar varnish for another project and was told just to get the spar urethane as they are the same, however I did not buy it since I was under the impression that they are entirely different things. So not to confuse things I am looking for something durable for my outside step and if there is really a difference between spar urethane and spar varnish. To further complicate things the plethora of choices and misleading labels are almost maddening so if you have some brands that are a safe bet as being what they are labeled like for the spar varnish that I am looking for please do share. I just found out that I have some tung oil and other items downstairs that are in fact blends and not pure product.

I don’t know what others do, but I don’t like to seal the wood for decking. No matter what you use, it’ll need to be redone someday. So I protect the wood every other year with some new stain/varnish combo. Every other year just clean it off with bleach and scrub it, then rinse and restain. If you try to seal it with something durable, it will wear off in spots in 4 or 5 years and look terrible.

A lot depends on the sun/rain exposure and where you are in the country. But Russell is correct in that nothing will last more than a year or two without needing refinishing. I’d go with a couple of treatments of Thompson’s Waterseal a year or some kind of yearly transparent stain.

If you insist on a clear finish go to a real paint store (not HD or Lowes) and ask for an oil based deep tint base with NO colorant in it. I just did this for someone’s mahogany door and other people have used it successfully. It goes on perfectly clear and has more UV inhibitors than marine or spar varnish.

It sits outside our back under a covered rear porch and only gets about 1 hour of sun a day and not direct snow or rain unless it is blowing like hell. Would something like a 1/3 spar varnish 1/3 mineral spirits and 1/3 boiled linseed work for this application. I was guessing that is what Russell was talking about with a combo but wanted to confirm.

I like low maintenance for decks because the harder the finish, the more work it takes to refinish it and the worse it looks as it ages. I believe your best bet is something like Thompsons because it has UV inhibitors that will help prevent graying and will be easy to reapply.

I don’t know much about spar varnishes but a varnish could be either a urethane or oil.

Your 1/3, 1/3,1/3 recipe is a slight variant on a popular blend. I used that on the deck of my one ton flatbed for years, renewing it annually. It did, however, build up eventually to a varnish-like look. If you did something like 1 part spar varnish and 3 or 4 parts BLO and and 3 or 4 thinner, I think you’d have a nice recipe that will work for you.

FWIW, white oak is nice stuff for outdoors but red oak, not so good.

Kindly,

Lee

If you want to varnish just be prepared for it darkening over time. I’ve put Helmsman on a small covered deck two years ago for a customer and it still looks good – dusty but good. BUT it’s on the north side of the house and it’s a door that they never use, so that deck never gets foot traffic. If you use this area a lot and will have furniture being dragged across it I’d still go with something penetrating so you don’t have to sand the whole thing down every couple of years in the future.

Does the BLO have any uv inhibiting qualities because I am thinking of all my garden tools and nice axes that are only treated with that and they all look original; granted they don’t see sun all day but they are older and used quite a bit.

Thanks a third time Charles. I have never come across that product. Did some Googling on it and watched some youtube vids and seem very high end. I have a deck that needs to be stripped and refinished. I give this a test run on that and see how it works. This willl give me another alternative to suggest to clients.
Now to find it at a local supplier to avoid shipping.
