I've experimented with dipping paper towels in very thin Plaster of Paris solution. Carefully spread them over the area and paint on more POP with a brush. It was very rigid when it dried, and I saw no cracks. Cheaper than plaster cloth!

Yes, this is what I did before. I like the vinyl because it spreads easily with a wet brush and dries firm and takes paint well. Thanks for all the ideas.

I am poor. I use paper towels covered with a very thin and goopy mixture of drywall compound (spackle). No voids or pits left behind.

And the Winner is:

Dap Vinyl Spackling

Got a gallon for $17 at Lowes. Got a lot done but need a little more.

It dries nice and hard on the plaster cloth and just spreads on with a paint brush. Easy to paint and won't crack.

I have used drywall seam sealer with excellent results. Also Woodland Scenics Sculptamold and have never had cracking. I over lapped the covering on the first layer then another single layer, then add the coating. Regarding the drywall seam sealer, it can be thinned with a LITTLE water too. Don't add too much water.
I forgot to mention that I use paper towels dipped in a very thin plaster mixture. Way back when I bought the Woodland Scenics plaster cloth. I soon learned that stuff doesn't go far on a large layout so I tried the paper towel and thinned plaster method. Much cheaper and it seems stronger.
By the way, you can add clothing dye to the water that you thin the mixture with for a nice effect. If you use a brown or a medium to dark green dye, ground cover becomes much easier. You can paint highlights on the dyed areas then add your ground cover.

Woodland Scenics doesn't sell Sculptamold. Theirs is lightweight hydrocal casting plaster or sculpting plaster. These products are OK, but for me, Sculptamold is the ultimate scenery material. Not as porous as plaster, but much sturdier and less exacting in the mixing proportions.

Sculptamold is a product of the American Art Clay Company, or AMACO. I buy it off Amazon in 25-pound bags.

Yeah. I never understood why everyone doesn't do that instead of the high priced version of basically the same thing.
Though I'm armchairing a long time now, when I do make hills, mountains I still use screen stapled to risers covered with plaster or spackle..Old old school but it works great..And 'dirt' cheap.
