There are two methods of curing.
One method is to lay a plastic sheet on top of the floor and let it sweat under the cover. A small amount of water can be sprayed under the plastic sheet over the next few days. This will help the floor to cure. You will know it is fully cured because the floor will become very hard, this takes around 7 days.
Another method of curing is to use chemicals. This is sprayed directly onto the floor. The chemical agent will break down after a number of days and leave the surface free of any of the curing agent.
