Reply to "Binding edges of homasote, priming, etc."

My layout is covered with Homosote with a few braces underneath with no sag.  I don't have mountains made out of plaster either. I do have about 20 Lionel cast locos sitting on it.  Some of the Homosote is 30 years old from an old layout.  I really don't think he would have any problems with it.  Use a good tape on the edges but clean them up first.
