After 1 winter, all 12 shutters on my house have begun to peel. Effin' drag, seeing as I spent hours scraping, wrighting, bracing and painting them.
I had primed w/ Zinsser cover stain spray. I second coated w/ HD Accent green spray. I topped w/ BMoore Urethane (custom color), the alkyd the store guy said to use, maybe the only oil paint they had (BMoore dealer).
Paint failure! More chips coming up, aaarrrgh!
NOW I see on the urethane can "for metal substrates only". The flex in the wood shutters may have let in moisture, etc. Brush vacations maybe. The dried paint has a rubbery, flexible feel.
Also, I guess the Accent paint may have left a gloss that the top coat couldn't adhere to.
The thing is, many of the peels come from under the spray, from under the primer, or from under the leftover old paint.
Anyway, now I'm set to scrape again.
My question: should I use a liquid stripper to get off the urethane paint? Will a thorough sanding do? Repaint with primer and latex? Throw them all out and just paint on fake shutters?
Well BilHam, 1 winter is enough for windows shutter to maintain its color. My advice will be, you can use dark brown color in particular. You can also try to apply silicon polish (2 coating minimum) over the paint to keep it intact for longer period of time. Best of luck for your shutters.
You'll probably need a liquid stripper to get them completely clean. Are these wooden shutters? If so prime with a good oil primer. I'd use an oil house primer which is a penetrating long oil. Coverstain doesn't penetrate as deeply. If you don't have stains to cover a regular house primer would be better for this. Top coat with a good acrylic house paint, preferably in a factory mixed color. Brush for optimal penetration. Don't use spray cans on anything. I'm not certain from your post if you are using aerosol or an actual sprayer. You don't need to topcoat the paint with anything.
