Sand back, seal with shellac (dewaxed). Then repaint.

If you are using the GF “Milk Paint” (it isn’t casein based, its more like a really nice acrylic), you should be able to cover in 2 coats with the dark colors. Lighter colors tend to work more like a heavy body stain in my experience. Bonds just fine to dewaxed shellac (e.g. Zinser Sealcoat) or Zinser BIN primer (the shellac based stuff, not the water borne version).

If you are making the stuff up from powder or “scratch” and it has lime and casein, then it will take many more coats to obscure whatever is below. This will also bond to the shellac or BIN just fine.

Never get in a hurry when finishing, that’s the most difficult thing I’ve learned!
