2" foam

[topgun3208]

I done a search on this and all I am getting is how to mount it to the benchwork. my question is this, is it used to mount track, scenery, so it is easy to pull up later on if one decides to change the layout?

It's pretty versatile stuff---some people (myself included) use it as a layout base directly on top of the bracing instead of 3/4" plywood, because it's lighter and fast to work with. If you use the Corning pink or blue extruded foam--which unfortunately doesn't seem to be available out here in California anymore--it has quite a bit of strength for all of its light-weight. It's also a good sound-deadener. I mount WS foam roadbed directly onto the foam. And stacked as scenery, one on top of the other, it's surprisingly strong and resiliant. I like it. Unfortunately, as I've said, it's not readily available in my state and I have to get it from Nevada. Something about the chemical composition being deadly to Spotted Owls or whatever the Ecologists here dreamed up.
But it is very easy to work with, and if you want to change anything, it comes up very easily.

You can use it for almost anything. I use the 3/4" variety myself. Only for my scenery, not for benchwork.

I used latex caulk to attach my cork to the foam, I used the same caulk to attach the rails to the cork. This will come up with a putty knife if you need to change it.

I have not placed any ground foam yet, but I painted the blue a nice sandy brown (Latex Paint only)

My layout is 2" foam glued to a 7' x 4' sheet of OSB (Oriented? Strand Board). The track is standard Atlas track on cork roadbed. I mounted the track and cork with Atlas track spikes, which seem to hold it pretty well.[:D]

I did this also, but when I switched to flex track the spikes would not hold the turns down as well as I wanted. I created some super elevation in the wrong direction. What would that be?? Inferior elevation??

that was going to be one of my ? also about mounting with spikes, but that was answered, thank you all who responded, took alot of the guesswork out of that one

I would follow Royal Oaker,s method. You could pin or tack the track down tempararily to check for problems and operation, but the latex caulk allows you to remove track buy simply shearing it up w/ a flexable putty knife, bread knife or whatever works. Nails will not have any lasting holding power w/o glueing.
DAP Alex Plus seems to be the favorite. You will need to weight the track down for drying and stop any creep.

Yup, you got the right acronym there. There's also MDF (medium density fiberboard) that I would prefer to other things because of its ridgidity. It doesn't warp like others, and it's much harder.
