Hi!

My little one finished a wood carving but she used markers to color it. Last time she did this, I used a water-based poly to brush over her carving but it made some of the markers run, probably from the solvent in the poly.

Does anyone have any recommendations on finishing over markers? Maybe some acrylic sealer spray can for finishing artwork??

Thank you!!

There are several different brands out there. Rustoleum, Minwax and Ace are the first that come to mind. A word of warning! Until you get good coverage, several very light coats and in a warm environment. That will help it dry and make sure it’s very dry between each coat. Putting it on to soon after each coat and/or to heavy will cause it to run. When that happens it could also cause the paint to run. So very light coats to be to begin with!!!

I like spraying shellac for things like that, but if alcohol will remove the marker it may cause bleeding and runs of the markers as well. Test it on a sample board.

Yes for the acrylic.
I would probably use Polycrylic
Applied lightly the first few coats as burlybob suggests

Polycrylic is just the Minwax brand of water based varnish. It will do the same thing as any other water based material. If it were me, I would use rattle can solvent based polyurethane unless you insist on water based material.

You don’t think solvent base will cause the marker to bleed?

Hi Helen!
I have had a hand painted sign blur in the past… so frustrating. I wouldn’t use any oil based topping and have had success with Diamond Wood Finish spray which is called Water Based Outdoor. As others said very thin coats and always test first.

Just go to home depot and pick some spraycan with laquer or shellac. Give it a few very light coats. Even if it dissilves the ink it will not have enough volume to make runs. After several coats you can give it a few full strength coats

Depends on the ink solvent in the markers. Use opposites to prevent bleeding. If water use a solvent finish like shellac or lacquer. If alcohol use wb. Should be easy enough to make sample boards and try things till something works. Use light misting coats 2 or 3, let dry to seal the ink then a little heavier.

Helen,

As noted by OSU55, you should be looking at opposites to avoid running.

Since you said water based poly created runs, then going with an oil based solvent should help.

Also, you noted that you brushed on the WB poly. Depending on the marker, there may be quite a bit of pigment from the marker just on top of the wood or in the pores. The brushing action itself may be moving some of the marker pigment as well.

So go with a spray (I’d recommend lacquer, just do it outside with ventilation) and like several other people said above, do one or two light misting coats to lock things down and then go with normal after that.

I’m sure you’ll get it just right.

Mike
