Topic tags/keywords: resource tip question trick yellow birch finishing sanding

Hi All,

I am almost done with my raised panels for my doors. The panels are yellow birch, the frame is of walnut handle padauk.
I want to apply a coat of pure tung oil and finish with shellac and wax. I am afraid of the blotching. I never worked with yellow birch before and I do not really have scrap pieces of decent size to practice on.

My strategy is:

Apply a thin coat of shellac as a sealer, sand very lightly (400-600) Apply tung oil, shortly wipe it off and apply another thin coat of shellac, more shellac with heavier cut (2lb I am thinking of).

If my strategy (shellac, oil, shellac …) makes sense I have some questions?
I read about shellac cut, I saw on this forum that a 3:2 seems to be a somehow an agreed upon cut as a sealer coat.

My understanding is that the first coat should be very thin, just to barely protect the wood but enough to somehow minimize the blotching.
Is 1lb cut would be more appropriate as a sealer coat?

What would be the ratio you would use for to protect against blotching?

Thank you for your input and advice,

Arnaud

PS: I saw the C. Neils method with wiping the wood with a damp cloth before the oil.

What is a “sealer coat” and why is it needed?

Agree with Clint. NO Sealer Coat. If you do that, how is the Tung Oil suppose to soak in?

Tung oil is first, shellac is if and when the tung dries.
Some Tung’s don’t really dry.

If you put shellac first, the tung will not soak in like Rick said.
