Thread: Grain filling Queensland Red Cedar

Good score!

What do you plan to finish them with?

Shellac will fill the grain. Ditto oil if used via wet sanding.

Otherwise, Neil has spoken favorably about Intergrain filler. Click

Ah sorry - I should have mentioned that. I want to finish them with Organoil Danish Oil. 'Tis easy stuff for a mug like me to use.

Thanks for your response.

Hmm, well with their Hard Burnishing oil, the finish is wet sanded and that builds up a grain-filling slurry. Job done.

They don't mention this approach with their DO however. Click

Hello Charleville

Have a lookat this recent thread, Wood Grain Fillers.
Now oil darkens red cedar a fair bit so try some out on a scrap before using the oil-based filler suggested there. See if you like the effect. Otherwise the shellac/talc filler works beautifully on red cedar and sands back to silky smoothness. As red cedar is so open-pored you will need a couple of coats of the shellac filler.

Good advice Brian.

I'm not a fan I have to say of adding talc, though it was common enough in the industry, as it turns shellac towards the opaque end of the continuum and may mean you lose the signature figure of Aus Red Cedar.

My notion was that, used as a sanding sealer, this actually enhances the figure. I add a little red oxide powder to the shellac/talc, sand back to bare wood when the filler is dry, then use whatever finish I have chosen. But I'm just a hobbyist. So it's something I do at long intervals.
What say you Ern? Do you think this dulls the figure?

Thanks for the responses, gentlemen.

I shall experiment a bit on some off-cuts and see what happens.

I recall from my earlier modest experience with grain filling just how nice the result was when the grain was filled to be darker than the wood itself.

However, as Wizened of OZ has noted, the red cedar does go pretty dark when oiled. That suits me as I shall be contrasting the cedar against some birdseye yellow stringbark so the depth of colour in the oiled cedar should give me the effect that I seek.


Yesterday morning, before I started this thread, I actually ordered the Ubeaut book on finishing. There is much for me to learn.

I get you Brian; thought you were bodying up with Shellac and talc.

Some cedar pieces I've restored had had grain and holes filled with English whiting I think. I'm told in a resto baby oil wiped over it and then Shellac applied blends it in but have never tried it.

Hi Charleville

Perhaps also try Burnt Umber as a colourant instead of Red Oxide. I recall testing it out once on red cedar but thought the effect was a bit too dark.

Thanks Wiz. Much appreciated advice. Will give it a try.

Grain filling red cedar is a PITA at the best of times, using a low building finish makes it nearly impossible.

On small items like boxes, used wipe on poly and sand every 2nd coat until finish was achieved, sometimes as many as 18 coats.

On larger items, lacquer 3 coats, sand, 3 coats, sand, ad infinitum until base built, then finish applied.

Implied is already used a sanding sealer as base coat.




Grain filing is only really needed for full gloss finishes, you can get away with a lot more on satin and matte finishes.

Thanks, Cruzi.

Lovely box, BTW. Very nice!
