Hi Everyone:
I made a stork to place outside my house when my wife gives birth on Tuesday. I painted the stork using latex paint. I want to cover the paint with a protective clear coat but I am not sure what to use. I don’t want the latex paint to be damaged by the top coat. Any suggestions would be greatly appreciated.
Thanks for your help!

I'm not certain, but read the can on water based polyurethane to see if it's compatible with latex paint. I'm almost certain it would be fine. It has the advantage of being very clear, whereas the solvent based finishes all have a slight amber tint which would make your stork look like it needs a bath.
Thank you for your quick response. I will check the label on water based urathane for compatibility.
Typically, waterborne varnishes are not for exterior use. Particularly, stay away from waterborne poly. Poly rapidly deteriorates when exposed to UV from the sunlight. Poly, whether oil based or waterborne, is not a good exterior finish.Howie.........
Jack,
Congratulations to you and Mrs. Jack
Are you sure you want a stork hanging around your house???...lol.
If your using exterior latex paint, isn't that made to wash off with each rain so it'll look fresh and clean?....that could be a problem with poly....don't know for sure..

Some of the paint is interior latex paint. I wasnt really thinking about the paint until after I painted it. My mind is on something else. Tahnks for your thoughts
My first thoughts are to use two coats, of a one pound cut of a clear shellac on top of the latex, did this on my work bench to lighten it up before varnishing. Anyway, for outdoors I'd put a top coat of spar-varnish, could yellow the white somewhat...
Good luck and let us know what you did and how it turned out.

What about an exterior grade paint, and skip the clear coat?
Just from my own experience. I used solvent based poly over paint in my bathroom and it looks kinda' nasty.
Jack, unless you plan on leaving the stork out on your front lawn as a permanent decoration...I think all you need is a couple of quicks coat of interior-exterior spray varnish. The kind available in cans at the local hardware store for less than $4.00. Apply it in light, even coats, so you don't get any drips or runs. It should lock the latex pigments in place and provide an adequate moisture barrier for a 2 or 3 week tour of duty out there exposed to the elements.
If it is only temporary, for up to a few weeks, the interior paint will probably hold up fine outdoors.

Thank You all for your responses.
I found a lacquer made to cover paint. It is a Krylon product called Kamar lacquer 517. It is specifically made to be sprayed over oil paint, acrylic latex paint, and water color paint. I found it at the local artist supply store.
It did not change the color of the paint when I used it and it has held up through hurricane Ivan.
