I’ve painted it for building bases. Just a spray plastic primer seems to work. It wouldn’t hurt to scuff it up with some 400 grit to take the shine off, but I didn’t bother and so far 2 years outdoors still holding up.

What type of paint?
Also, what kind of glue do you guys use on this stuff? Years ago I tried building some storage boxes out of this material but had trouble getting glues to hold.
I’ve been using the Bartwerks adhesive of choice:…Goop. Holds up well, even in this climate. It will melt the veneer if you aren’t careful when applying it.
There’s not much gluing surface when putting corners together so I run a piece of 1/2" square PVC along the inside corners and sometimes screw the coroplast to that along with the goop.
And just for added strength, run another piece along the bottom to help keep it square. I also do that to add some much needed weight to the structure, as this stuff is extremely lightweight.
And to help when it gets windy, I’ll add a 1x6" piece across the bottom so I can place a rock or brick on the inside. I have had a building or 2 get blown off the layout and across the yard a few times.
I found the key is to add the bracing along the inside corners and along the top and bottom. Usig screws helps while the glue dries and makes it stronger. E6000 works great. Since I use wood for the outside I also can use a pin nailer to help hold things while the glue dries.
By the way looking good Ken
Geez that thing is huge. You’re right to worry about it blowing away, that’s a lot of sail area. Really looking good with those intricate roofing angles all over it. You’ve got a ton of shingling ahead of you! (http://largescalecentral.com/externals/tinymce/plugins/emoticons/img/smiley-foot-in-mouth.gif)
Turned out a bit bigger than what I anticipated.
Right now I’m working on supports for the underside of the roof, so I can lift it off in one piece and not have it fall apart. Shingles will be the easy part, they come in 16" square sheets… (http://www.largescalecentral.com/externals/tinymce/plugins/emoticons/img/smiley-wink.gif)

You left yourself wide open on this. Wait till Rooster sees this. Its not too late for the Shut up Rooster.
Too Late

You want it top heavy not bottom heavy. A pair of 2x4 chunks screwed under the roof is better than a pair of 2x4’s screwed to the base. The Russians asked for proof of this or just stop talking about it Rooster. So that is what I did, but said it for years under the radar.

Yes, dear…I will take that under advisement…(http://www.largescalecentral.com/externals/tinymce/plugins/emoticons/img/smiley-wink.gif)

Why is that, Roos? Why does it make a difference?
The building will tend to rotate around its center of mass. Making the center of mass high, makes it less likely to rotate and tip over in the wind.

Wouldn’t the same thing apply with the COG down low?
Not so much, the body becomes a lever to tip the weight… (with the weight low)

Editing only from my personal observations of coroplastic and other lightweight structures I built that have “ALWAYS” been outdoors in PA climate for well over a 5yr period of time.

Steve, as a sailor you should know about sails and how sail boats will lean over when tacking across the wind. A building will do that if the center of mass is low, but if its high, it has less tendency to lean over. Of course all bets are off when that F4 comes roaring down the street.
David, now you are not making any sense at all. If a ship has a high COC, it will be extremely unstable, and if there is much top hamper, it will put its lee rail down in even the lightest of breezes. For a ship to be stable, you want its COG at or below the waterline.

I was wondering why a pair of red slippers were laying next to it…(http://www.largescalecentral.com/externals/tinymce/plugins/emoticons/img/smiley-wink.gif)

If the water gets that high, we’re all in trouble. But a brick makes for nice ballast…
