Normally we would recommend leaving a sealing coat for the full 24 hours then sanding prior to the next pour.  In theory you could leave it the 10 -14 hours before it becomes firm but tacky then re-pour straight away.  However in practice, this is not always very practical especially in a room as you may need access to the far side to do the pour and help spread the resin before moving back towards the door way.

How long approximately do you have to leave Glass Cast 3 base coat (sealer) on wooden floor boards before you can apply final top pour? and does the base coat require sanding before applying top coat?
