How long does it take for my piece to set?Updated 22 days ago

Once you have poured your mixture into the mould, you want to allow this to set for 40-60 mins. If it’s a hot day it might be a little less and if it’s a cold day, it might be a little more. Jesmonite gets hot whilst drying, so wait until it is cold and hard to touch. Once you have sanded your piece, leave it for a further 24 hours to ensure it’s fully set.
