Can I Put A Clear Coat Over Paint?

okremodeling

Has anyone ever put clear coat over laytex paint. I am making a mailbox and would like it to last a long time any suggestions. I painted it with a good latex paint.

I wouldn't, clear coats are usually aggressive formulas that might cause the latex to lift, craze or bubble. You might want to think about an automotive paint system for longevity.

Use a deep base or accent base, varies from manufacturerer to manufactuerer, without any tint in it, it will dry clear, you need to thin the paint down a bit.

Use a high grade exterior acrylic for color retention. (factory ready mixed if possible) The best would be a 2-part Urethane. A clear coat may not do what you want.

Minwax polycrylic should work I believe. Just read the can. Not positive how it will hold up to weather ,but I've used it on doors and decorative wall indoors. pd

what about those glaze in faux finishes?

I repainted a set of interior cabinets about 6 years ago and put a semi-gloss Polycrylic finish on it. I scuffed the paint before I put it on. It's held up great so far, but again, it's interior. Not sure how that combo would hold up to weathering.

dont put a clear over exterior paint. The clear will wear out in a couple years and you'll be re-doing it. Go to your local PPG store and buy Pittsburgh Paints Manor Hall Gloss / Semi-Gloss Exterior. Great paint and it's very, very durable and washable. Manor hall semi and full gloss are interior / exterior rated. I painted some trim on my home with it and I hit it with the PW every spring and not so much as a flake.

I know this is 3-4yrs after you asked the question but I've used polycrylic over outdoor art on doors and mailboxes with nice results both in Florida and Wyoming. The paint I used was acrylic artist paints and faux glazes. Latex? That, I haven't done but you may as well try it. I don't think it will cause the paint to fail but just in case, try a sample piece and leave it outside for a while.

Polycrylic works except it has no UV protection in it...Exterior water-based poly should be fine. Right, 4 years later...so helpful...

A HO asked me to put a clear coat on an existing mural that was painted on the side of her garage. With some research, I came up with ArborCoat Clear by Benjamin Moore. So far so good.

I had a customer do the exact same thing but they used a marine product!

Being that ArborCoat is designed for decks, I figured puting a product intended for horizontal surfaces on a vertical would certainly last longer and it has UV protection.
