For optimum performance when using your paint roller sleeve, wash your roller in water, this in turn will help your roller cover to soak up as much paint as possible. Fit the roller onto the frame and dip your roller sleeve lightly into the paint, ensuring that the paint covers less than half of the roller, proceed by rolling it backward and forwards on the ramp of the tray to evenly distribute the paint on the roller cover. Roll the paint onto the surface in a zig zag like pattern and begin to fill the space by laying off with long, parallel strokes.
Its important to not leave a paint-covered roller exposed to the air for a long length of time. Wrap it in plastic wrap and make sure to clean it completely after use.
