Splicing 2 PVC foam sheets together

I'm thinking of connecting two 4x10" expanded foam pvc sheets together so as to cover my 9'4" tall by 11 foot wide wall as part of the visuals for a home flight sim. I'm concerned about adhesive residue creating imperfections on the screen side prior to priming and goo painting. Is there any adhesive that's most suitable to connect two Expanded form pvc sheets together in this fashion without damaging the sheet finish?

Thanks

Re: Splicing 2 PVC foam sheets together

Hello and welcome to HTS.

I assume you are going to frame the sheets. Another thing...are you sure about the AR? 9,4 tall = 16,7 wide for a 1,78 AR, and if so, we are talking about a 228'' screen. Can i ask you what projector will you use to fill this enormous screen?

Thanks for the response.

I have two BenQ W1080ST projectors. Planning on setting the projectors overhead my cockpit seat perpendicular to each other projecting onto the curved screen in a similar fashion as in the attached picture. All input and suggestions are appreciated.

I tried to post the pic but don't have the 5 post minimum

Hi GreekLazarus! Welcome to HTS!

I found a page from a plastics supplier that might help you (http://www.tri-dee.com/Sintra%20pvc%20adhesives.htm), but basically the article shows that thin cyanoacrylate ("super glue", "krazy glue" etc.) gives the best bond.

You didn't ask our opinion of what screen paint to use, but unless you already have your Goo paint, or can get it for less than regular interior latex or vinyl paint, you might think about NOT using Goo since there are better options. We reviewed Goo paints and found them wanting and nowhere worth the retail price they charge.

Great link. Thanks harpmaker. Actually I was looking into goo but I'll take your recommendation on best screen paint to use. This is for a medium - high fidelity flight sim.

Thanks !
