You’ll have about 45mins working time with sculptamold but as we go through the process you want to get it on the layout and then after leaving it for 20mins come back and smooth the surface with a wet finger. Otherwise your scenery will look like dried cottage cheese rather than a sub base that is mud or clay.
I just popped it on the layout with my hand as you can see its not really smooth at this point but that doesn’t matter. Also because nothing is secured to the base I was able to easily spin the foam sheet around to work on the otherside.
Here is the backside before applying the sculptamold
Before we finish this we need to check that the roadbed will fit, but thats for tomorrow.

You’ve gotta love sculptamold, it is my go to scenery base. I have used it as a cottage cheese look for sloped uneven transitions between rocks . The uneven look, slightly smoothed, works great for a fast flowing creek. You can dry brush the creekbed and then simply apply a gloss coat, just enough to seal the base, and it looks just like moving water.
Loving the updates, thanks Gordy!
