casting manhole covers
Hi, my name is Ferg, from Ireland but living in Thailand, and I'm a complete rookie in the art world. I've been working as an architect for the last 15 years or so and now I'm trying to break out and do something more creative.
I was wondering if anyone could help me with a little art project I had in mind. I want to make plaster casts of some small manhole covers. I want to make them in plaster, so the first step is to take molds of the steel manhole covers out in the street, pavement whereever. the ideal material for this is a quick drying liquid (for working in the public street) which sets in minutes into a flexible rubbery mould( so the mould can be peeled off without tearing). normally its used for making dental moulds, but would be very expensive in this application. so I'm looking for an alternative, some kind of homemade paste? playdough? i tried acrylic latex sealer but it was far too sticky and slow drying.
any suggestions appreciated......thanks
