Using expandable foam for scenery

[beiland]

You're right about the foam packing pieces. I was thinking just stacking various foam packing pieces into some sort of shape that was roughly what you want, then glue the pieces together, but don't cut them - - glue quilt batting onto the shape, then paint and add scenery elements. Saw that technique in a YouTube video (https://www.youtube.com/watch?v=9C6aHEoUWYg)

A lady compares a dozen or so different glues to glue foam sheets together. If you don't want to watch the whole thing, you can start at 1:06 and watch for a while, then skip to 5:00. Or you can watch the whole thing and see the results with each different kind of glue. She gives the pros and cons of the better ones.
The winner: Glidden Gripper paint primer - - yeah, a paint primer beat all of the other products she tried. I plan on putting it to the test this week on my own layout.
