@Tall J posted:...I'm debating on putting. 1in layer of foam down on top of the homasote for scenery purposes. I know as far as cons, its harder to get the track to screw in and tie in. I think the foam could be good for cutting out inlays where the buildings will go and give me some flexibility in cutting in a river/stream that will run from the back of the layout down towards the front. What is everyone's thought on that? I keep going back and forth and would love some insights....
Putting foam over the homasote on the entire layout would defeat the purpose of using homasote in the first place - sound deadening and screw holding. Keeping track solidly in place on foam requires glue, which will add work if/when you want to reuse the track.
Depending on how the underlying framework was built, you may be able to cut openings for a river. You can also add foam on top of the homasote in selected areas to build up the scenery. You can "plant" buildings by adding plaster/joint compound/etc. around the bases.
