I've made the mistake of watching some bloke on YouTube make a textured battle map and thought I could do it too.
I bought a 6x4 drop sheet and covered it in caulk, then I sprayed it with watered down PVA and covered it in sand.
So far the sand has stuck, but bits are flaking off so I don't know if it will hold on the long run.
Does anyone have any tips on what I could do to try and improve it or stop the sand coming off? I probably put too many layers on. I may try covering any white patches with a mix of caulk and sand.
