<human>:  What is the right way to use a paint roller?
<bot>: The right way to use a paint roller is to start from the top corner of the wall and roll the paint in a “W” or “M” pattern. Make sure to apply light even pressure.* Work in small sections at a time, making sure paint is covering the entire wall. When you reach the end of a section, use a brush to paint in the edges and corners. Roll off any excess paint on a tray or similar surface. Let the paint dry before adding a second coat.
