Can I paint Benjamin Moore Eggshell Paint over GF Water Based Top Coat

Tammy
by Tammy
I painted underneath my bar with two coats of Benjamin Moore Eggshell Paint in a flint color. To keep it from getting damaged by my children's feet while they were sitting on the bar stools, I wanted to protect the paint with a top coat. I lightly sanded with 220 sanding pad and applied the first coat of General Finishes High Performance Water Based Top Coat in satin.
When I went to buff with the 220 sanding pad as suggested in GF videos, some of the underneath layer of bright yellow showed. I guess I did not sand well enough before or I sanded to hard.
Nevertheless, I need to know if after giving the underneath of the bar a thorough sanding with 150 grit sand paper, if I can repaint with the Benjamin Moore Eggshell Paint in a flint color or if I have to get all the GF Top Coat completely off first.
If I do need to get it all off, how do I know when it is all off?
This is my bar and you can see where the yellow paint is coming through :-( Please help!

    You will have to remove the last coat or the new finish will not adhere.

    Did you sand before you painted the flint? You didn't mention if you primed before painting the flint! I personally always sand, prime, finish coat, sealer coat in that order. No matter what paint I use. Also, I get a more vibrant color when I prime.

      I hired painters and they said they sanded and painted two coats. They said it was ready to ready to put the top coat on 😩 So in all honesty I'm not sure what they did. It's a good lesson for sure!

    You do not have to sand all of the top coat off. To get the best adhesion with the least work, I would give the piece a quick sanding with heavy grit sandpaper just to 'break' up the finish a little. Don't worry about how much or how little you get off. Then apply, liberally, liquid sandpaper. This 'tacks up' the finsih. Just follow the instructions. I use this all the time, almost never actually sand anything, and always get good results. To get the best coverage, I would use a bonding primer tinted close to the color of your paint. Then paint. Use a light grade sanding block--or polishing sanding sponge. This is not actualy sanding; it is just a light going over to smooth any paint ridges so that you have a smooth finish when you run your hand over the piece.Then use sealer if you want. One of the things you might have done is that you didn't let each layer thoroughly dry before you sanded.
