Oil based poly would damage the vinyl decal as would any kind of solvent based coating.
Vinyl decal on polyurethane.
Vinyl decals were never intended to have a clear coat put on top as far as i can discover within product specifications.
There are three ways that you can seal craft projects including those with vinyl.
After varnishing you cannot remove the stickers unless you first remove the varnish.
I am thinking that the decal would stick better to the smooth less porous poly coating than it would to the bare wood.
If you have a wall decal matte finish and not super strong adhesive use a very light coat of polyurethane.
However i ve seen many do it with great success for nearly 20 years.
Well today we are going to share not just one way but three different ways you can seal your vinyl decals.
Vinyl is a synthetic man made material made from ethylene sourced from crude oil and chlorine sourced from common salt.
It s so easy relatively affordable and they last a long long time.
The polyurethane tends to curl the edges of a vinyl sticker and with the lighter adhesive the strength of the adhesive can break down.
With a tray like this with vinyl on it i would definitely recommend doing an epoxy resin.
Those are a spray sealer like polyurethane polyacrylic spray dishwasher safe mod podge or an epoxy.
To get the best result use the right vinyl for your job and print it in the same way.
When working with polyurethane always make sure the room is well ventilated as it can give off harmful fumes.
Mod podge is another product that i have heard customers state they have used over their wall decal stickers.
Varnishing over stickers will seal them on the wood making their presence practically permanent.
Here s my take on things.
This allows you to creatively change the look of the surface to fit your tastes and needs.
Let the paint totally cure dry before applying a poly clear coat to the top deck.
And i ve yet to see any major issues.
If leaving your boards natural wood brush or spray minwax polyurethane on the wood board tops let cure for 24 hours and then lightly sand with 400 grit sand paper.
You may be right in thinking that a coat of poly then the decal and more poly may be the best route not sure about that though.
