I have decided to use styrene sheets to make a concrete "slab" in an industrial area on my layout. Some may reference my previous post where I asked for suggestions on this topic. The styrene sheets appear to me to be the easiest method.
Now I have a couple of questions re details:
1) What would be a typical concrete expansion joint spacing? I think joints on residential driveways are typically 10' or 12' apart. But I am wondering if that standard is the same for industrial concrete areas.
2) When should I scribe the expansion joints into the styrene - before painting or after? In some cases, I might be able to seam the sheets at the appropriate spacing.
As always, any advice will be greatly appreciated.
Bill
