Sand and Dry Grain-Filled Doors

What happens here

Two coats of Aqua Coat grain filler are applied to the cabinet doors, with a drying time of 45-60 minutes between coats. After the second coat, the doors are sanded again, this time with 220-grit sandpaper, to achieve a perfectly smooth surface. The presenter states that all doors are now ready for priming and should be left to dry overnight for optimal curing.

Goal: After two coats of grain filler, the cabinet doors are sanded smooth with 220-grit sandpaper and left to dry overnight.
