The last coat over plasterboard joints and patches, the one that gets sanded back super smooth so the paint goes on without the repair showing through.
TopCoat Lite is a lightweight, ready to use topping compound that goes on as a finishing coat over your base coat. It's easy to spread, it sands back by hand or with a machine, and it takes paint once it's dry. It also works on its own for filling small cracks and holes in plaster walls and ceilings. Tools clean up with water.
