I built a small dresser out of birch veneer plywood and wanted it to be completely dark. I used a "Dark Ebony" Minwax grease based stain and covered surrounded by two coats of Minwax oil base poly (sanded in between) but I've immediately decided I want it to be much dark with a slightly different threatening mahogany color (more brown and not so black). My plan is to get a small can of grease based paint to be exact the color I'm after, thin it beside mineral spirits and paint over the project. Is this ok? Can I apply another layer of polyurethane over the paint once it's dry? Also, what is a angelic thinning ratio to start with for the paint/mineral spirits? I will be brushing this.
Answers: Stain soaks into the wood. You can paint over ,but you must apply a grease based primer first,after sand it down. Polyurethane is a sealer. It sits on top of the wood, but it doesn't soak into it. Same entry goes here, you must sand first,to rough up the surface,consequently use a oil remains primer. After that you can use oil base, or water base paint, than let it completely cure beforehand resealing it with polyurethane. You can use a grease based or dampen based paint over an grease based primer. You can't use a dampen based paint over a grease based paint. With primer it's OK . It's confusing.
You can paint over polyurethane if you sand it weakly then apply a primer, after paint. I think you're asking, however, if you can stain over polyurethane. I would enunciate definitely not. If you sand the poly all the path off you may hold a chance, but the exotic stain would bleed into the old stain and you won't find the color that you were hoping for. Sorry for the unpromising news but you'll hold to sand it all the style down to bare wood and start over to win the correct stain color. May I suggest that you try an inconspicuous spot like the inside of a drawer or the bottom of the drawer or something first to bring in sure. Stain is tricky. Always test the stain on the wood you are using first surrounded by an inconspicuous place because the color on the can probably won't exactly match the color you carry because of how absorbent the wood is ie: harder or softer woods. Good luck, if you approaching my answer vote it the best, I could use the points:-)
