UHU Por is by far THE BEST glue for depron & EPP foam. It does not melt the foam and will glue anything to foam or foam to itself. The elastic adhesive film is colourless (transparent) and waterproof. Perfect for gluing together Depron, EPP or building lightweight polystyrene foam model airplanes. The bonded joints also retain a degree of flexibility so unlike CA glue, UHU Por will not crack and split.

Apply the glue in a thin layer to both surfaces and allow the surfaces to become touch dry before bringing them together. For surfaces which you cannot allow to dry apart before bringing them together, you will need to allow a longer drying time for the glue to cure. A thin layer of this glue will be touch dry in about 3 minutes and will achieve full bond strength within about one hour.
