milwrd posted:I had to try it myself because I couldn't believe it, but Glidden Gripper works great. Not only for foam to foam but I also used it to adhere foam to my plywood deck. Here is a good video on the subject from back in 2012. I know there's some newer adhesives on the market that work well too.
Looks like a more than adequate replacement for Gorilla glue and very likely a good bit cheaper. I seldom use all the Gorilla glue in the bottle once you reach a point where you cannot squeeze any more air out of the bottle your leaving water vapor along with the remaining air and the glue left will soon cure in the bottle. I wonder if the Glidden Gripper is anything like ceramic tile mastic ? I have used it on occasion to glue foam and it works fine though it cures a little slower than Gorilla glue. One positive aspect of the Glidden Gripper and ceramic tile mastic is they don't foam up. Probably don't fill gaps as well though. A small aside on Gorilla Glue and Great Stuff foam. Basically the same substance with a great deal more foaming agent in the Great Stuff. I don't think anyone has mentioned Epoxy yet, or I missed it. I have often glued Styrofoam with epoxy, it works fine. In fact most of the folks building home built aircraft use epoxy to glue Styrofoam. This could be yesterdays news as I have not run in the circle in a number of years and I can see Gorilla Glue working just as well as epoxy in many if not most instances. j
