What am I doing wrong? Answered

So, I've been wanting to make bottle cap pendants for awhile now, but every time I go to paint the bottle caps using my acrylic paint, it dries all sticky. How do I prevent the paint from peeling or coming off if it gets wet or something? I have some acrylic sealer, but I don't like the sticky texture. Will the sealer make it not sticky?

Are you sure you're using acrylic enamel paint? The kind that's baked on?

See my hobby tumbler


Fill it with coarse dry sand or fine crushed glass and tumble for a couple hours.

It will get every nook and cranny so the paint will stick everywhere.

If you are painting on the inside of the bottle cap heat on your barbeque outside not in the house, to burn off the plastic seal on the inside of the cap, then tumble to polish.

After that prime, primer makes the paint stick.

Then paint, if you use water based paint let the paint dry for a day and seal with clear lacquer.

A good paint job depends on what prep work you do before laying down the paint. You need to take some sand paper and ruff up the surface so the paint has something to grip onto, especially acrylic. You would be better off using oil based paints rather than a water based like acrylic. But if your preferred medium is acrylic (as is my wife's) then find yourself a good primer that is compatible with acrylic and will hold well to the metal.

Do you actually mean "sticky"? Or do you mean "soft enough to press a finger nail into and peel it off in a flexible layer"?

If you mean the latter, that is just the nature of acrylic paint - it dries to a layer of flexible plastic. Just protect it with a layer of varnish (model shops often sell a clear sealant to paint over acrylics and stop them wearing off.

I don't know your answer, but at the cost of bottle caps
you can test the texture at very little risk ;)

It sounds like your acrylic paint isn't compatible with the ink already on there:

You can remove what is on there with some 600 grit wet and dry paper.

you may be able to find a solvent suitable to remove the existing paint/in Try a standard paint remover.

You can try to seal them with a suitable primer paint. A spray can may be best. Make it a very thin coat.
