removing ca stain with acetone?

Re: removing ca stain with acetone?

I'd say no since you are trying to remove it from the cellular structure of the wood. Maybe gold or silver leaf to cover it?

That's an idea..

But was still thinking of just soaking it in a bath of acetone so it would remove it from the cell structures..

Would it be out of the question to apply the CA to the whole top? It remains transparent when cured, and maybe it wouldn't adversely affect the transmission of light through the early wood pores.

Would it keep the wood from absorbing the dye I'm airbrushing on?

CA stain goes really deep. I tried to cut away some on a clock I was making. It never did go away even after removing almost 1/8" of wood. I don't think soaking in Acetone will work but it can't hurt anything. I would apply more CA to the area to try and mask the stain. You can easily finish over the top of it.

Your dye stain is definitely not going to absorb as strongly into a CA coated surface as it would into bare wood. However, mixing the dye with the finish and applying with an air brush is a technique that is used successfully, for example by guitar finishers and others. I don't do it, so I can't offer any details, but I have tried applying it with a brush, and have been utterly unsuccessful at getting an even color.

will seal the pores, and then lacquer, will hide the stain.

Test first

I think I would be testing a sample of the Norfolk Pine / Ash of about the finished thickness with some CA glue on it soaked in acetone before soaking the finished piece in a bath of acetone.

Better to find out that the sample reacted badly than the piece.

My chemistry is very rusty but keep in mind acetone is an organic solvent and is highly flammable as a liquid and a vapour.

Darrin,

If you are airbrushing, you can successfully color over sealed wood with dye. Once the piece is CA sealed, sand it back to 180 or 220. DO NOT sand finer because color won't adhere as well. Color using the airbrush. Do not try to saturate the color, because you can't. Too much dye will behave like rain drops on a car hood. Worth practicing on the scrap piece mentioned previously.

Once the color is applied, lightly seal it with a spray of lacquer. Too much lacquer will activate the dye. When the lacquer dries, spray it again. Do not sand between lacquer applications. Build up several coats of lacquer. Wet the surface each time and the lacquer will flow into the previous layer.

Once cured, wet sand with 400 or 600 wet/dry paper by hand. Use an angled light to look for any peddle-like texture from the lacquer spray. Your goal is to get a dead flat surface. But don't sand so aggressively that you cut through the lacquer to the colors layer. Once you do this, you are hosed. At this point, you will have a very nice matte finish. You can polish that up to whatever gloss you like using automotive compounds.

I have this process detailed on my website at AirbrushingWood.com under Education - Tutorials.

Try using plain old airplane glue to fill cracks and voids--no stains and finishes easily!

I was just trying to deal with some CA stain today. Pretty difficult as it soaks in so deep. I tried a curved scraper for the first time and it did seem to help some in combination with sanding at final grit (240 in this case).

Lots of excellent information on your site, Joe -- thanks for putting that together and sharing.

One day I'll start dabbling in coloring turnings... for now, I need to build a shop first.

Safe spinning,
