Hi everyone,
Hopefully some knowledgeable-types here will be able to help!
I'm needing to make a mould and then casts of some brass plaques. There's a similar thread already on this, however, my plaques are set into a wall and cannot be removed. I've no way of mounting anything around them nor can I drill into the wall, so I'm thinking I'll need to fill the plaque and hold a solid board against it to give a flat back face.
For the mould: Are there materials viscous enough that (a) won't slide downwards in the time it takes to set and (b) set relatively quickly (I don't want to be standing there for 2 hours!) - if so which?
I'm UK based.
I have permission to do this.
The original moulds no longer exists.
Thanks in advance,
Fin
