Hi there, this post might give you some direction. https://www.hometalk.com/34306684/painted-countertops-from-laminate-to-granite
Not sure of your question but epoxy resin is hot and looks amazing. You can make your counter top look like quartz, marble or granite or become an artist and make artwork. Just get your epoxy resin and mix it. Add the colors and pour and using blow torch to rid of buttons and a heat gun to creat amazing swirls and color blends. It goes over roughed up laminate or whatever on countertops.
Here is a hometalk link for diy countertop painting.
Additionally - Here is an idea that I find exciting and interesting for your consideration. I hope this helps.
Home Depot has a counter paint. I used it to cover a 40 year old print yellow top and it worked wonders. I couldn't believe nor could any one else!!!
