Making a mould for casting concrete

It's that time of year when old garden railway enthusiasts' thoughts turn to, "What can I do on the railway this year."
IMG_3650.jpegMrs Edwards has this planter and I am thinking, if I sectioned it up, it would make very nice G Scale walls. I'd like to make a mould and cast lots of them from concrete. Now last time I did this was way back in the days of the Sandwell Valley Railway when the moulding compound had to be heated up to a high temperature. The moulds I made were very successful and I'm still using the walls I cast on my new railway, but Mrs Edwards' best saucepan unfortunately never recovered from its ordeal.

I understand that the process of mould making is now much easier and that concrete moulds are made by mixing two liquids together. Has anyone on the forum tried this? If so, can you help me? I need to know which stuff to buy as I understand it sets to make moulds of different hardness depending on what you get. Also how to do I calculate how much I need to purchase.

Any help and advice, as always, gratefully received.

Thanks, Keith
 
Hi Keith, Cant help on your request but eagle eyes on anyone else helping out. if you cant get any info you might fancy as day out to this place the chap there is very helpful as its what he sells ! ps while your there take a look behind the sheds in the car park and let me know what you think.
