GAF Posted January 3, 2016 Share Posted January 3, 2016 I'm building a new diorama using a 1/72nd Italeri C-47 and CG-4A glider. To use as a base, I have a 18"X24" bulletin board with a cork surface (the kind you hang on the wall to post notes on). I was wondering if any of you have any experience using cork as a base for gluing grass mat or sandpaper squares? I don't see white glue affecting it, but I am not sure about its suitability when it comes to warpage and adhesion. Something this large I expect to bend a bit. Here we go: Thanks!

Black Knight Posted January 3, 2016 Share Posted January 3, 2016 Cork swells when damp. You'll need to seal it very well to prevent that. You can glue grass to it with PVA glue but as that is water based expect swelling and shifting until the water is completely evaporated. 1 Link to comment Share on other sites More sharing options...
GAF Posted January 3, 2016 Author Share Posted January 3, 2016 Might be best to use the back. It is panel board (or similar) and wouldn't have the swelling problem. Gary Link to comment Share on other sites More sharing options...
old thumper Posted January 3, 2016 Share Posted January 3, 2016 Cork tiles were originally sold as a wall covering, I don't know what glue was used to apply them but I assume it was something like Evo Stick. 1 Link to comment Share on other sites More sharing options...
Badder Posted January 3, 2016 Share Posted January 3, 2016 Personally, I'd use the cork side, but seal it very well first. The cork side will be easier to pierce or cut into if you want to 'sink' something below the surface, like the base of a wall or a fence post. Just remember to seal any cut or piercing as you go. If the cork does swell and/or lift at any point, just let it dry out and use CA glue to stick it back down, then seal it again. 1 Link to comment Share on other sites More sharing options...
old thumper Posted January 3, 2016 Share Posted January 3, 2016 A non water based varnish would seal cork well. Link to comment Share on other sites More sharing options...
GAF Posted January 3, 2016 Author Share Posted January 3, 2016 Ah, thank you! Will see what I can do then. Gary Link to comment Share on other sites More sharing options...
Jimbobtheflimbob Posted January 3, 2016 Share Posted January 3, 2016 (edited) I made a diorama for my B.O.B using a cork daplay board from whsmiths. They sell ones without the wooden border, which are one sided and have a wooden bottom. It worked well, and i painted it with acrylic paint and put pva glue on it without a problem: http://i.imgur.com/JS3spZ3.jpg http://i.imgur.com/2a2Jv2W.jpg Will Edited January 3, 2016 by Jimbobtheflimbob 1 Link to comment Share on other sites More sharing options...

OTOH, this is what the back of the bulletin board looks like. Dark gray tarmac? Gary Edited January 3, 2016 by GAF Link to comment Share on other sites More sharing options...
dcrfan Posted January 4, 2016 Share Posted January 4, 2016 Model railway modellers routinely use cork tiles as track base and glue ballast down by flooding on PVA well thinned with water. I've used this method successfully for years. I've never heard of the cork track bed swelling nor have I ever heard of need to seal the cork.
