Finishing Deck - Interior Primer/Paint Mistakenly used on first coat
I have an issue I need help with.... I went to a big box store to buy materials to finish my deck... They recommended latex stating that the new technology within the latex paint makes it last as long as oil based anyway.... and because it is easier to handle I went this way....

I'm painting the railings and spindles a white.... They recommended a primer and paint combination product Behr Ultra Premium, rather than a stain..... So this is the direction I went. After applying the first coat, I realized I need more... so I take the lid to get another gallon. This is when I realized that the big box had sent me on my way with INTERIOR Primer/Paint, rather than exterior....

What are my options? Can I put an exterior over top to seal it, or does it need to be stripped down and completely start over? HELP!!!!

I'm assuming your in Michigan, and based upon the winters you get, its going to fail. I would try sanding as much off to bare wood as you can and start over. A good power sander with 60 grit should get most of it. If your spindles are round, it might be easier to just replace them.

Your other option would be to finish it with exterior paint, wait a couple of years for it to peal on its own and go from there. Sorry for the bad news, but I don't see any other way.

Thank you for your reply. This is basically the same conclusion that I had come to.... And in 2-3 years, whatever it lasts.... power wash the paint all off and go with a solid color stain.....

Your thoughts on Oil based vs. water based?

On my own house, I like to use a slow drying "long oil" primer and two top coats of a premium grade water base paint. I'm partial to Benjamin Moore so I'll use Aura as the top coat.

On my jobs I'll still use Aura, but may switch to an acrylic primer if I need a faster dry time. Some of my smaller jobs may last only one day, and it just dose not make sense to use an oil primer that needs to dry overnight.

I wish we could get oil anything out west here.

Decks just require regular maintenance no matter what imo.

I bet if you first went to a real paint store this whole thig would not have happened.( just MO)

couldn't agree more. Big Box Store was handy and open late on the Saturday that I wanted to get the "stuff", so I went. Mistake!
