Cork Roadbed

I have used Midwest cork for a very long time. I even used cork I had for over five years still in the box. I do, however, paint my cork before laying down the track. The cork on most of my present layout has been in place for over eight years. I have never noticed any shrinkage in the cork.........................Paul

When I used cork, cut from roll stock,  I had curling in spots. I had to re glue.
