Repairing styrofoam flotation

I have a 1976 Flying Scot that is in very good condition for her age. However, the styrofoam flotation under the seats is crumbing away in small cells and ending up on the floor of the boat. Does anyone know of a way to seal that flotation or repair it to minimize crumbling? Thanks, Doug W.

well depending on how much trouble you want to go through, you could take the foam down, wrap it in a bed sheet, and put it back up with the bed sheet well secured. is that the kind of answer you're looking for?
