My covered outside air layout at the second house is coming along. The problem is that in coastal Mississippi the humidity is 110% a lot of the time. Plus in one area I want to expand into, misting rain can blow in, although I’ve got a plan to address that. The question is, how does excessive humidity and possible light rain on the layout surface affect scenery materials? I’m especially worried about how scenic cement is affected, basically a white glue. I’m afraid I can’t ballast the track or put any ground cover down. That humidity will make the ballast soft after it dries and that any rain that gets on the surfaces will turn the scenery to slop. I know that lichen really absorbs the humidity and gets very soggy, it happens on my main layout when I’m gone for days and the AC is turned off. I have zero other space for my layout over here, but I really do want basic scenery. I already know I have to use plastic buildings and that EVERYTHING has to be picked up if I’m not right there. There’s cats around plus at night we also have raccoons and possums in there at night. I’ve already found evidence of nocturnal wrestling matches on the layout. This come back to a question I asked awhile back. How bad do you want a layout? I want one here in MS pretty bad. It’s either this or no layout. No other options. It’s pretty pleasant down there a lot of the time but the extreme extenuating circumstances make this one a pretty hard case.
