i hope someone can help me,,i made a kitchen island for my son and he wanted it with a walnut finish on it,,,personally i dont like a dark finish on pine,,but thats what he wanted,,lolo,,so i got some wood pre stain and put it on first then applied the stain,,,needless to say it looks bad,,so we decided to paint it it using a airless paint sprayer,,i sanded the wood to 120 grit and used mineral spirits to clean it up with,,i was wanting to use water based paint so clean up would be alot easier,,,do i need to put a primer on it first before painting and do i need to sand some before i put the paint on it,,,and can anyone tell me a good paint to use thats goes on good and lays flat,,
