What To Put On The Exterior Of A Timber Frame

Markon

I am having problems chooseing a product for a timber frame I am building. The home is very open, so there are a lot of points where you can see the timbers inside and out. The inside of the timbers was coated with linseed oil, the exterior nothing. The Customer what the exterior timber to look as close as possible to the inside ones. I asked the Timber folks if I could use linseed oil and he said no, he said it takes so long to dry that in climates that it gets real humid, the mold will grow in the oil, turning it black. So I buy Cabots Australian Timber oil, Then I read a thread below of a linseed oil type problem with it!

Want a natural, not shinny look. Think I'm scared of oil now.

Also, the whole ceiling inside is car-siding. Sofitts are car siding. Same story, you can see them in and out. Inside was treated with Deft Satin laquer. What can I put on the outside that will kind of match?

FYI: Timbers are Douglas fir, Car-siding is Pine

Thanks

I don't think you would have any problems with boiled linseed oil, it dries. I have always added it to primer and never had a problem. And I reduce and use a chemical sprayer on my privacy fence.

I agree, what I've been told is there is a difference between raw linseed oil and boiled (clarified) linseed oil, the process removes cellulose and proteins or something (it's been a while since I had this conversation) which is the food the mold will use to grow on your oil... it's similar to clarifying butter where you remove the milk solids the remaining liquid will last a long time without going rancid.

The guys in new york that sell the infrared silent paint remover also carry a full line of linseed oil paints and are quite knowledgeable on the subject, I think you should talk to them, and they have clear linseed oil for sale also... if nothing else it may help you in your search for something else, I think the guy I talked to who knew quite a lot was named soren...

you can find their number here:

As Metalbender noted, I'm also skeptical about the claims the linseed oil will turn black.

In case you didn't know, linseed oil is the medium most frequently used in fine art oil paints, since the Renaissance. There are plenty of oil paintings that have survived hundreds of years without turning black, so there are some results.

Also, how humid could it be in Kansas? I don't know, but it's definitely more humid here in New Orleans, where we routinely have summer days with 100% humidity. I have some wood that's been finished with boiled linseed oil, and it looks great, with no discoloration whatsoever.

One thing to note is the application: rub it on, then rub it off; you want a very thin application. You can always apply multiple times.

I agree completely Sikkens is great in terms of how well it does its job, it really is the best. That being said it is made of some pretty nasty stuff. Not sure if that is a concern for you?

on our timber frames we use a 50/50 mix of boiled linseed and turpentine for all of our interior beams, but never outside as mildew would be a problem for sure.
