paul 2 posted:I decided to add some wood between the posts to give the walls more places for glue and stability. I had a piece of embossed paper that looks like stone. I cut it into strips to glue on the back of the flex walls because there is no brick pattern on the back. I want to glue the paper on with Weldwood contact cement. But am asking here if this will attack the foam of the flex walls. I want to add this to the back because the walls will be sticking up about a 1/2 inch above the sidewalks. Any help appreciated. For the time being I am going to work on something else till I find out if the contact cement is safe to use. Thanks Paul........Pics
I very much doubt that is foam safe. It is great for laminates and layers of similar hard materials, but very volatile in general.
I don't think traditional rubber cement would work out either.
They make foam safe adhesive in caulk tubes, available in big box store paint sections.
You could adhere the paper to thick contruction paper or thin, raw art board (shoebox thick cardboard) with rubber cement, then attach the board with the much thicker foam adheasive to keep things smooth and flat. This would allow for some toe nailed divits in the foam for a better bond too.
Rubber cement is an old school printers staple. It works excellent for paper and thinly appied, doesn't shrink and pull paper causing warp (roller burnishing the excess out). Just keep it off inks to be safe, but most are fine with it IME,, The excess dries fast and rubbing the drying excess will ball it up to be brushed away, leaving a very clean edge if done with care. At times, more excess actually helps leave a cleaner edge and surface sometimes; like a wet eraser to clean with.
