The Flat Finisher Box is used to apply mud over taped joints on walls and ceilings. Typically users will start with a 7" to apply the first coat (bed coat). Once the mud dries a 10" box is used to apply the second coat (finish coat). The 12" is used to apply the third and final coat (skim coat). A Flat Finisher Handle is needed to control the Flat Finisher Box. Loading the Flat Finsher Boxes is quick and easy with a Loading Pump and Filler Adapter.
