Oil Wood Finishes - Options

[wimpy]

Starting to think about how I am going to finish the exterior of my hardwood house. I like the look of teak oil, but it is not very durable. At least the Cuprinol brand isn't, and at 900 baht a gallon, it ain't cheap. Someone on another forum recommended a mixture of motor oil and diesel oil. Has anyone tried this? Any other ideas? Seems that tung oil is unobtainable.

Teak oil is as good as you want

if the wood is in direct sun you may need to renew every other year or so, but that is the same for all of them

I think the Berger (?) make is cheaper, B800 for a bigger can

We used the Cuprinol Teak oil. 2 coats and it's wearing well.

There's a Thai product called Delight. More of a stain but with various shades. It seems to protect well. A house nearby did 2 coats about 5 years ago and it's still good.

I applied Cuprinol to a mai taeng counter top in my sala. It gets a lot of sun. After just 3 months, the oil appears nearly gone. I wonder if mai taeng is less absorbent than teak. It is a heck of a lot harder.

There's a thread on it
Search and you'll find it

[wimpy]

I did, and I tried emailing the person producing it. No response. Sounds like when they do sell it, it is in rather large quantities.

stuff another coat on, easy enough

Quite. ICI, themselves will tell you that Teak Oil is not suitable for long term protection, but, it's not really that expensive, looks good and is easy to apply.

[robtherich]

Tung oil is bloody expensive and to do a good job needs half a dozen coats. That's if you can source it.

[robtherich]

Really all depends on the conditions and what kind of finish you're looking for.

Protection versus looks. And of course cost.

Easy enough when it is just a table top. When it is a whole house, there is a bit of labor involved. I just want to accntuate the natural color and grain. I would rather not have to reapply every 6 months. Most of the "stains" I have seen look pretty bad in my opinion. They hide the natural appearance too much. Think I'll do some weathering/aesthetic comparisons with the commercially available teak oil versus some combination of motor oil / diesel oil / turpentine.

We sprayed ours.

agreed, the labour would be quite a bit but you only need redo those areas affected by direct sun about every two years

even if you don't, you get that nice weathered look (if teak) and the wood does not suffer

and keep away from those stainers, they are horrible

good idea, and any overspray would not harm anything

I have been doing some experimentation with different combinations of oil and solvent.

The one that looks the best (in my opinion) and is holding up the the best is shown on the right. It is one coat of shellac (at the suggestion of my foreman) and two coats of a 3-1 mixture of turpentine and cheap motor oil. It seems to bring out the redness of the mai taeng, and hasn't faded much. On the left is the 900 baht a gallon teak oil which has faded noticeably after 20 days in the sun.

Higher concentrations of motor oil went way too dark.

[DrAndy]

maybe try sunflower oil, or peanut butter?

looks good though

hi chaps, ladies and other....
Today i got a quote of unbelievable propotion, 650k badt to sand and laquer the house, but wait not all of it just 100m2 floorspace about(280m2) wall space.
No wonder this guys got a brand new car!
Whats odd is the floor price is reasonable still over the top but reasonable(24,000). This was for labour and materials, after going to global the wife found out the cost of beyer primer and laquer or stain for outside for 23,000 badt. Admittedly we need to think termite proctection, sand paper but something has gone very wrong with his calculations. The wood is 90% old golden teak, just the floor is mai daeng.
After this and my sudden heart attack, the wife is talking to him to see if there is a labour only option as we know the crew, they work hard and that price seems reasonable.
Anyone got any advice or suggestions for treating the wood?
We arent really that bothered, but my main detest is colour inside, i just want the natural colour to come out.

Cheers for the heads up.

I have just looked at tung oil, through this forums threads and others, what is the current situation with this for using on a house? Its natural, great, but how long does it last? I would prbably only use on the interior not exterior. Cheers

[DrAndy]

Interior last for ages,same as Teak oil

apparently it is not easy to obtain

try using motor oil as suggested elsewhere!

Don't tease us, pics please! All the best with it.

Woods like mai taeng and mai sak need serious preparation in order to dry the surface of the wood sufficiently so that it will properly absorb whatever oil you use. I have used acetone (or similar solvent) to scrub the wood to dissolve out the surface oil. Only then will the Teak Oil properly adhere to the wood and last a few years.

[benlovesnuk]

I have teak on the walls and redwood on the floor with a mixture of mai padu as well.
For me the teak is sufficient and old enough to only need a finishing look, and protection.
Therefore the teak was planed and so needs little sanding, only where the planed level could not be consistant over the wood. Then tung oil rolled on with roller and repeated about 5 times. The outside we are considering berger primer and stain with colour on the exterior as it has uv protection and is cheap. The look of this being outside not as important.
Can anyone recommend a team of people to sand my house?
Much appreciated.

[benlovesnuk]

What about teak oil, im thinking chaindrite teak oil for the interior spaces 2 coats and bobs your uncle. For the exterior chaindrite clear matt wood stain as it has uv and water protection and hopefully wont need to be redone for a reasonable amount of time.
We have worked out our issues and hope to start finishing the house soon.
I would like tung oil for the wood in the kitchen if anyone has any ideas of where to get it i tried contacting the company that was seling it but no answer, any other ideas?
Cheers for the beers

[benlovesnuk]

It seems that this compositon wil be good,
1) first use acetate to take out surface oil, this is quick to evaporate so oil must be applied in qick succession.
2) apply teak oil, the first should be thinned down 20% to improve its application into the fibres.
3) wait for 24 hours to apply the 2nd coat. Apply next coat.
Then it says about using shellac to finish, it mentions sanding back and then applying it.
Anyhing else to consider?

Does ths sound right? Is ther anything i have missed in the chain?
