Exterior Paint Question

Sorry for posting here, but there is no Exterior Painting category.

In trying to get a re-finance done I was under the gun to get a repair painted quickly. I couldn't find my primer, so I painted bare pressure treated wood with exterior semi gloss, mostly so the inspector wouldn't see an unpainted surface and deem the repair incomplete.

I want to have this last and paint it correctly. What is the best process? Can I do primer over the semi gloss paint and then repaint with the semi gloss? Do I somehow need to remove the semi gloss before priing? Should I replace the wood altogether? I'd hate to do that as the wood is brand new>)

Thanks, as always for your good advice.

Never mind guys...answered my own question by calling the info line on the paint can.

In case your interested, they suggested sanding off the paint or replacing the trim. Ugh. Such is life.

Yeah...I didn't see your post or I would have replied. I have the same problem...didn't prime a piece of 2X6 trim (things are different out here...lol), but figured sanding and 2 coats of ext semi-gloss would hold up ok...

Well, it did...for about a year...its almost completely gone now. Lucky the wood is PT...so another sanding and priming should work. Of course then it won't mach the other 75' or so of trim on the front so I'll prob be sanding/scraping and redoing the entire thing.

Originally you sanded, then put on two coats of paint , without priming, right? My issue is only with two new pieces of trim so I may just replace them. It may be easier than sanding all the paint off.

Well, I think you MAY be able to sand/scrape the loose stuff (if there is any)..then use a quality primer and topcoat. Let one of the Pro's give better advice...but yeah..might be easier to replace.

And no...I didn't prime mine...all I had was interior primer..and I figure that would be even worse.

I was PO'd enough that the only piece I had to replace was the double bevel, triple compound miter, super "how the heck do you cut this" piece on the whole house. And it was only about 8" long...so not much wiggle room.

Primer doesn't help too much after the fact

IMO replacing the wood is kind of drastic, I'd let nature take it's course and prime and repaint it later..... of course if you feel like sanding it down....

New PT wood can be difficult to get paint to adhere to until it has dried out from the PT process. When feasible it's best to let it weather before priming and painting.
