Bases for diorama

[AntonyWolfson 0]

Hi all. I'm new to the forum and I've been building a 1/16 King Tiger for 18 years I kid you not. I am looking to build a base and have seen some foam bases. What do you recommend. I want to position it in rough terrain. Half sunk in water. I've seen what I think is foam. How do you prepare it to paint on? Is this what people tend to use? Thanks

Get some of the builders insulation foam, its fine grained so can be cut easily. I've just finished a base were i pressed air drying clay over the foam to form the textured groundwork but for 1/16 you'll need alot of clay so maybe  you'd be better using something like claycrete (basically paper mache). Plenty of good tutorials on youtube to check out. I like to mix dried soil from the garden with paint and pva as a final layer to add loads of texture to the goundwork.
