I’m making a crokinole board that has a plain birch playing surface and outer rail that match. I’ve already covered the playing surface which is still separate with a waterbased polyacrylic. Now for the base; I’ve dyed the base dark with an aniline dye which is also waterbased. Then I’ve glued the natural birtch rail around that and I plan to clear coat both of them together however I’m worried that the dye will run into the natural birch when hit with the waterbased clear.

One way to solve this would be to use an oil based poly instead however I worry that it will yellow on the rails and look different than the clear playing surface (deck).

I also know another option is to use a shellac as a sealer over the dye.

So I’m just wondering which would be the best route to go here and perhaps there is something that I haven’t considered then please let me know. Thanks.

Use two light coats of de-waxed shellac to seal it.

Rob, if you don’t to darken the lighter wood, use blonde or super blonde shellac.

Some dyes, Trans Tint liquid dye is both water and alcohol based for sure, since I use them alot. So if using them, you have to do an oil based wash coat over it to seal it.

Good point. Shellac can still be used, but it would have to be sprayed, in very light coats.

Like you and other have stated Rob,your dealing with like on like, dye and top coat solvents,in this case water.The top coat if brushed on will cause a percentage of the dye to come off or more around. If you’re spraying it your shouldn’t have a problem at as long as you apply polyacrylic the way you’re suppose to. If you’re brushing it on then you do need to seal it off with some dewaxed shellac.

Thanks Jim, I can spray it so I’ll just do that then. That great because I wanted to do the light coloured sides at the same time. Much appreciated.

Glad to help Rob just don’t puddle the polyacrylic by spraying a super heavy first coat. I use water base dye and polyacrylic all the time.
