i,am new to the cut out seen i was wondering what kind of plywood to use.

I live in Ohio and need some thing to hold up in the snow, but lite enough to carry back and forth from storage. i would like to start out with a Grinch that is about 6 feet tall.

I had plywood in the past, but it never fails, no matter how much sealer or clear coats, moisture always gets in and warps them. Even during storage in my attic I pull them out every year with another new curve. I purchased and am switching all mine over to the coroboard (plastic cardboard). A local sign shop ordered it up for me as the company only sells wholesale, but he sold it to me at cost for $18 per 4x8' sheet. Call your local sign shops and see what they can do. It is pretty flexible so i am actually doubling mine up and using 3m spray adhesive to sandwich them together. Use a plastic primer and the paint holds great.

I use ACX 1/2" plywood.  I prime the entire 4x8 sheet with Zinzer primer then use regular indoor paints.  Usually the oops's at the paint department.  This year Ace hardware had a get a quart free promotion.  Got a can of Santa red and grinch green.  So far they have held up to the NH elements well - no sealer coats.

Hello fellow Buckeye,

 

I've been making and displaying plywood cut-outs for more years than I care to admit.  I typically use 1/2" exterior grade plywood, one side sanded smooth; available at any home improvement store or a lumber yard.  For a 6' high piece, I'd use 5/8" (little hard to find) or 3/4" thick; the 3/4" material is heavy, so call around and try to find the 5/8" material.

 

I agree with NH-Dave, use a good primer on all sides, including the edges, after you cut out the shape.  I use two coats of primer.  I prefer exterior paints and use two coats of exterior paint. I'm not a fan of any kind of sealer, as some, actually most in my opinion will yellow over time.

 

I don't have any problems with warping.

 

Be careful with storing them; keep them as vertical as possible, leaned against something.  If they're stored for 11 months in wrong position, bent possibly due to something leaning against them, they natural take that shape.

 

Oh, one more thing, when you display them, leave the bottom off the ground a couple inches.  That'll prevent them from being exposed to moisture from the ground constantly.

 

Good luck and have fun making them.

Sorry, by sealer I meant the Kilz sealer/primer on the bare wood. I did all my originals with 3/8" plywood trying to keep em light (6' hanging Santa from gutter, snoopy on the mailbox, etc.) I agree 1/2 or 5/8 will hold up better and would be best for ground items, but I needed lighter stuff for the roof and hanging form gutters.

I looked back at my post on the coro as well...$12 a sheet from Grimco.

Gopackgo.....from one packers fan to another! I use a lot of hot glue. As I mentioned above, I 3m spray glue two sheets sandwiched together with the grains going opposite direction to make them stronger.

The best solution I have for mounting them is to glue the back of the cutout to a piece of PVC pipe (1 1/2"), use the u shaped hanging brackets to help hold too. Then pound a wood stake in the ground that fits inside the PVC, the cheap bundles sold at lowes. Now just run a screw in the back through the PVC and into the wood to keep it from turning. I mount my LOR controllers in pairs this way too. If you painted the back of the coro the hot glue can pop the paint off. Therefore I drill a hole in the back of the coro (not all the way through the front) lined up with the screw holes in the brackets, now fill the hole into the coro with hot glue and over the bracket tab. In essence it is a hot glue rivet.

If your hot glue is too hot it will melt the coro.

For hanging from the gutters I use the vinyl siding j channel and 20lb fishing string to tie it down at the bottom. I did have my plywood hanging Santa flip up on the roof one year from the wind.

Whatever I can get my hands on! I use the thinner stuff like 1/4 inch for smaller pieces, and the thicker like 1/2 inch for the bigger ones. never had a problem with em. I get almost all of my wood for free. I've used crappy reclaimed wood and just sanded it smooth first. Again I've never had a problem. I use acrylic paints and varnish them. Some of the cutouts are 12-15 years old.
