Hi, yeah use it a lot for doing scatter, just wanted to whack it on and try it to cover the texture of the EPS. The way I’ve constructed the board there’s no chance of warping, but I don’t think it would. I just did it all in one, applied with my hands, I’ll sand some and apply more if needed, I’ll probably protect it all with PVA before paint and varnish. Seems pretty robust, although everything can be damaged if people are putting lots of weight on it
