I tend to use both Cellucaly and Durham Water Putty.
Advantages/Disadvantages
Slower drying--- can be + or - (takes a while, but allow great manipulation of the base/terrain)
Does not dry well by heating or blow drying… tends to curl the edges.
Thicker so great controlthen pouring or spatula work on plaster.
Random thoughts on it -
-The Celluclay is great for terrain, but slowly drying.
-Add a good dollop (engineering term for a tablespoon +/-) so the edges do not curl up.
-It tends to be strong and less brittle then plaster, but not as strong as the Durhams Water Putty.
-I prefer it when I am doing non-desert terrain. Desert terrain I use Durham.
-I mix it adding a little ground color acrylic paint to it. This eliminates it natural gray tone showing through place my paint brush missed.
-After I lay it out I sprinkle good old road dirt - that stuff in the gutters in front of the house – on top, press it in with my fingers and leave it to dry… Blow or vacuum off the exceed and you are ready to paint and dry brush to your hearts content. See pix below
Useful stuff – one more weapon in the arsenal for me.
