It usually takes Crack Heal 920 2 to 3 days to completely dry out. Once the crack filler has dried out it is recommended to see if there are further cracks appearing within the filling of the crack filler.
In case there are still cracks being evident over the cracks, it is recommended to apply a thin layer of Crack Heal 920 over the dried surface with a scrapper or spatula to cover up the micro cracks.
Once the cracks have been filled & the area is clear it is recommended to paint over the walls matching the color of it so that signs of repairing are not evident
