(1) DIP ROLLER — Paint is supplied by dipping the roller into a paint tray or a 5-gallon pail. Excess paint is removed by rolling the cover over the ramp of the paint tray or over a mesh grid inside the pail; (2) FOUNTAIN ROLLER — The roller has a hollow core that is filled with paint. Pores in the core allow the paint to saturate the outer fabric covering. (3) PRESSURE-FED ROLLER — Paint is pressure-fed through a supply hose to the center of the roller. Like a fountain roller, a pressure-fed roller has pores in the core that allow the paint to saturate the outer fabric covering.
