How long does it take for my piece to set?Updated a year 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.
