Finishing questions
May 5th, 2008 at 7:02pm
 
Hello,
When using Tung oil to finish my bowls, I have been saturating the bowl as much as possible, allowing it to soak in for about 2 minutes, and then wiping off excess and allowing to dry.  My question is that I have been doing this procedure again about 24 hours later but am wondering if this is necessary for a quality finish or not.  It seems as though the second coat does not penetrate very much and I end up with a sticky surface for a couple of days. 
Also, when using Mylands Friction polish are two or more coats necessary?  I have been doing 2 coats but am wondering if the second coat is merely re-liquifying (is that a word?) the first coat and then reapplying it.
thanks,joe

To start off, whose tung oil are you using?

I have been using Formby's tung oil.  When that runs out I have some Watco Danish Oil that I want to try out; I am guessing the application and question I have will still apply with the danish oil.

I never cared for Fomby's, it's possible it's old

An oil finish works best when you wipe off the oil on the first coat or two.

As to the Mylands, each application adds more depth to the finish.  It isn't unusual for me to put on 5 or 6 coats on a pen.

I bought the Formby's about 2 months ago, but who know how long it was on the shelf at the store.  So a turning should be able to take two or more coats of oil even when applied in this manner?

Good to know about the mylands thanks Smiley

It also depends on how dry the wood is.  I have a piece that is going on 5 coats of oil, and all have taken about 24 hours to dry.

I would imagine if the wood was oily that it might not soak up as much, or dry as fast.

I believe that if you check the lable on the Formby's you will notice the absence of a major ingredient, tung oil.  Don't know if there's actually in it or not, but it ain't on the label.  I also believe that you need to let the oil finish sit on the wood for more like 30 minutes before you go back and wipe it off.  Just follow the directions on that.  Anyway, let the finish dry at least to the touch before applying the next coat.  Then you can simply watch how it is soaking in.  When you get an even coat with no irregularities, then you know you've applied enough and it is time to allow it to cure before buffing.  I have a piece that I'm working on now that soaks the finish in so fast that it looks like there's wax on the surface.  Each coat gets better though, so I'm on the right track.

Somebody who has some Mylands help us out here.  Is there anything else in Mylands other than shellac?

Doug, I've always called Formby out on the lack of tung oil in the bottle.

The latest MSDS sheet has a ingredient called "Modified Soya Tung Alkyd Resin".
Who knows what the heck that is. But if I had to guess, I'd call it soybean oil... which makes it very similar to Watco Danish Oil.

Ron, if I remember right, that is what Russ says about most of the oil finishes, soy bean oil and way too much mineral spirits.  Gets real aggravating when they change formulas to this type of combination and you don't realize it until you've put a couple of coats on a piece and you get strange results.
