I have a wood bar outside made of pressure-treated wood that has sat for a couple of months. We want the bar to have a slick surface like an indoor bar where you slide your beer across the top as we have a party in a couple of months where the bar will be used. My intent was to apply a Fix All (which adheres to wood) to cover the grain and knots, then sand, prime and paint (oil-based). But while I was away, the contractor did the job without first covering with Fix All that I had purchased. It looks awful, grain shows through the dark brown paint. I intend to remove everything and start over. My question is, after doing research, some polyurethanes state that you need to remove all paint before applying. The oil based paint I selected is for exterior use, high gloss. But I would like to apply a layer of UV resistant, high temperature and humidity tolerant high gloss top coat of something. The "something" is my question. Can't use epoxy which has a nice thickness to it because it reacts to heat and humidity. Any suggestions? Much appreciated.

I give up, what's Fix All?
No way would I have ever used Pressure treated plywood for a bar top for many reasons!
Just to name a few, it's soaking wet, full of voids and flaws, Ect.
No way would I be applying poly over paint!

Unfortunately, the bozzo contractor installed pressure treated wood while I was not there. Really infuriated me, as I agree with you. I would never have put PT wood on top but figured since he makes bar tops he would have used regular wood. So, given this situation I am planning on scraping all of the paint off and redoing it, but first applying a coat of Fix it All to cover the cracks and knots (you can find it on the home depot site, among others). Yes, I would have liked a nice slab of interesting wood that could be treated with a couple coats of non-yellowing, UV and weather resistant poly but no such luck.

don't use poly outside. You should use spar urethane.

bar tops are typically a 2 part epoxy. bondo also works to fill holes if painting.

I agree- Spar varnish is fine for outdoor use. The wood, though, would have to be stained, not painted. For the pressure treated wood, it may be necessary to test for moisture.
