What happened at your workbench today?

So you are carving thin foam for the walls? Or will it form the master for ultimately resin moulding?

This is to glue onto the exposed sides of besser blocks. It is 30mm thick xps foam sheets. They are cut to fit the space, "normal" liquid nails works well on it.
They are not really "carved" as such. Thou i do run a knife lightly along the mortar lines to start with.
The detail and relief of rock edges is just pushed in with a old worn out small phillip's head screwdriver that has been ground to a point. I just run the screwdriver along the rock edges pushing it in say 5mm, then just push in any extra detail as needed. Pretty quick and easy to do.
There is next to zero mess of bits of foam to clean up, as the detail isn't cut out and xps is a lot stronger than the white packing foam that gets little bits everywhere.

Thanks I have something similar to that, must give it a go.
 
I got the other wall finished off last night after tea, whilst watching anime and chatting with my wife.
This is the first time I have tried working with xps foam.
Its very easy to do and fun.
I am very happy with the results, you can get great texture and depth pretty quickly.
The only minor mishap, don't use tamiya putty to cover joins. It slightly melts the foam :(, i should of just used exterior grade no more gaps.
I think the number of stone viaducts and walls on the railway will be increasing greatly, lucky i model the RhB :D

Very impressive, I guess you are using external grade PVA to glue together?

Are you using it outside? If so what are you UV protecting it with?

Yes it is for outside. I will undercoat it with a mix of modge podge tinted with black acrylic paint. That undercoats it and seals the foam it also protects it from the varnish.
Next coat will be just acrylic artists paint.
A couple of topcoats of outdoor polyurethane matt varnish to protect the paint and seal it all up.
Will it last? I can't say as this is my first try at it, but I have used these paints and varnish on plastic outdoor garden ornaments.
They have been standing up to the elements well.
I will say if it fails.

Not sure if you have such paint sold where you are, but you might also try a test piece for comparison with just a couple of layers from a masonry paint test pot (mid stone is a good all round shade which can be subtly tinted with acrylics). Just a thought.

May be worth a try with some photo uv protection, but nit sure how it would effect the foam?

Acrylics tend to last fairly well outdoors - just because they can be water soluble doesn't mean they're not robust.
