11B Posted November 19, 2014 Share Posted November 19, 2014 Good evening all. I need a bit of help and advice please........ What is the best way to make some rock faces like the ones below? As I understand it most people seen to use polystyrene or cork. Has anybody on here made any? If so, what method did you use/ Any how easy was to get a realistic look? Thanks in advance. Kind regards Ian Link to post Share on other sites More sharing options...
HLT 0109 Posted November 19, 2014 Share Posted November 19, 2014 Ian, I have had some pleasing results with DIY filler on different bases. The plaster sticks well to polystyrene or wood, especially if covered first in plaster bandage, and the results depend on your own ability to replicate the ruggedness of the finish. The mix needs to be fairly thick and it is best if you can mix some colour into it so that it doesn't show white if chipped. If it does chip, it often helps the rugged appearance. If you want the rock face to be vertical, it will be best to apply most of the plaster before fixing the block in place - so that you can lay it down. You can add to it as necessary when in place. I haven't achieved as good a result as your prototype pictures but I think I could with more practice. If you have a large expanse, it could get heavy.

Captain Nick Posted November 20, 2014 Share Posted November 20, 2014 Hi Ian I have had some pleasing results with foam insulation boards which are readily available from DIY stores and builders yards. Glue them together, carve to the general shape of the hill and rock face then attack them with an array of implements both blunt and sharp. Don't forget to think about the strata at the location you are modelling. I then use a mixture of artex, filler and wood glue to make a paste which I put on to the foam. When its dry, you can attack it again and also repair and add more gunge until you are happy. When that's done you can weather with an array of colours and washes. Here is the link to my layout which you may find of help. Needless to say that it is a very messy process and don't worry about foam crumbs getting into the gunge as it only adds to the overall effect.

KalKat Posted November 20, 2014 Share Posted November 20, 2014 That picture reminds me of the way that 'set in bag' cement powder looks if you break it up. The rock appears to be a metamorphised sedimentary type perhaps? Otherwise, you could use fibreboard/sundeala/notice board broken up, set upright then plaster coat?

jcm@gwr Posted November 20, 2014 Share Posted November 20, 2014 Although I haven't tried it, I've heard that after spreading the filler, push on some slightly scrunched-up cooking foil, remove it when dry and you should have some good strata effects. Good luck, Jeff Link to post Share on other sites More sharing options...

Kind regards Ian Here is the one I was looking for yesterday, Carving Foam, of course,you need not be as extreme as this, develop it in the way you want it to be. Ok, American, ad pushing, ignore and use the technique or others. Here was a first attempt (and only) of mine..........before, I tackle a 16.foot long, 300.foot high, backscene,on my layout The 16. foot long backscene,maybe I will get on with it sometime next year.
