What is the difference between Celluclay and polyfilla (stucco) Is there a difference, because the powder sure looks the same in the bag. Also what is the difference between these two and plaster of Paris?
P.S. I thought I posted this yesterday but don't see it anywhere, so if this is a double posting I apologize!
There is a big difference between Celluclay and Polyfilla. The Celluclay is a form of pre-mixed paper mache. The pollyfilla is a form of plaster. The difference is that Celluclay takes longer to dry and can be resculpted somwhat after it has dried by adding water. Once pollyfilla sets it is set. I personally enjoy Celluclay better as I find that I can add scenery over the course of a few days. It also had a slightly matted earth texture to it. The down side to is that it can take days or even weeks to fully dry and it can warp as it dries. To avoid this put in lots of white glue and score the base. Plaster of paris is similar to polyfilla but holds better detail.
The plasters are good for casting building walls and such.
Hope this helps.
