I am working on a TV stand to match my last project (coffee table.) The top is stained and the rest is painted white. I used a paintbrush first, then changed to a small foam roller for the paint. I was hoping to avoid excessive sanding for lines. Here's my problem, I applied the poly and when it dried, it looks yellow. I am assuming that some of the stain from the top transferred into the poly can. Now I have a piece that looks horrible. I have started to sand it down to the paint, but it's taking forever - my sander isn't holding onto the discs, they just fly off.. not sure what's going on there.
So, here's where I need help...
1 - Is there a better finish than poly for use over paint? Something easier, less messy?
2 - Is sanding it out the best way to get rid of the yellow poly? Since I used a roller, the paint has a little texture, so I have to sand it all the way out to get rid of it.... so basically have to start all over again with painting. :(
3 - What is the best way to use a sprayer with paint? I have used one with poly, but I'm very nervous to use it with paint. The paint I'm using is a semi-gloss so it's kind of thick. Would it be good to mix paint thinner with it?
