Adhesive for attaching Filon to roof
Howdy all. I have been working over the past few months on repairing my pop up truck camper after the roof had an RUD (Rapid Unscheduled Dissassembly). I've been reading up on all my options for getting the roof back on and have located a place in town that stocks Filon which will save me on $1-200 worth of shipping costs. The question that's making me cross-eyed at the moment is what adhesive to use to glue the stuff down with.
My TC is made with wooden ribs, lauan ceiling, and Styrofoam insulation that is skinned with Filon. Actually the original roof was probably closer to flex roof which is just a textured version of Filon. Either way it's a continuous sheet of FRP (fiberglass reinforced plastic). The front edge is curved down so the Filon has to conform to that contour. The side walls of the roof section are a laminated Filon/Plywood/etc that are attached to the wooden roof ribs.
Adhesion surface would be approx 95% Styrofoam and 5% wood
Other roofing options such as Rubber/EPDM, PVC, and TPO roofs have been eliminated due to the fact that they all need to be stuck down to a sheet of lauan or similar hard sheet roof which I'm not adding. Aluminum has been eliminated also so those options aren't even on my table.
Adhesives----
-I see some say contact cement which to me is a general term. Lowes has DAP Contact Adhesive but reading the fine print says not to use it with Styrofoam. The RV dealer I'm getting the Filon through said they use contact adhesive but I haven't asked what type yet.
-Some say Stabond E-183 which is actually the recommended glue for Filon but I'm not sure if it will eat the foam that it will be glued to. At $174 for the gallon + $30 hazmat fee + shipping costs via special carrier--- this is not a gamble I want to take. I believe it is applied with a spray gun and is extremely flammable.
-I just stumbled on a Titebond product that I can get on Home Depot's site. It's http://www.homedepot.com/p/Titebond-3-5-gal-Greenchoice-Advanced-Polymer-Adhesive-4319/203506897#.UkHs_MakpdwTitebond Advanced Polymer Panel Adhesive. I just spoke with their tech support and it sounds like it would work pretty well. It costs more than the Filon I'll be getting but if it works then it'll be worth it. It trowels onto the Filon and is moisture activated so it sounds much easier to work with.
Anyway, I'm looking for some experience from the RV forum on the best product to use. I'll see if I can get some picts posted soon and this will give me a place to add anything else I may find....
