Give yourself about 3-4 hours in total. This includes creating terrazzo chips and also allowing your piece to set. It’s worth noting we do advise you leave you final piece for 24 hours but unless you like watching paint dry, you won’t be needed whilst it does its thing.
This craft is a really nice project to set aside a day to do, that way you can take your time with each step and get even more creative.
With regards to the amount of time it takes to sand your piece, this depends on the mould you have chosen! Sanding does require a little elbow grease, especially if you are revealing terrazzo chips in your design.
If you have opted for a marbled effect on any of your pieces, you won’t need to do much sanding at all. Facepots and Shells only require the bottom to be sanded which takes about 5-10 mins.
If you’ve opted for terrazzo chips then it will take you a while longer. For coasters, tealights or trays you can spend about 1 hour sanding, but that depends on how visible you want your chips to show. The process does take time but the end result is really rewarding.
