Prep the Materials
Watch video of this step.
When you purchase your paint, ask what type of brush and roller is right for your job. Rollers have different naps, or fiber lengths that correspond with different types of paint and desired finishes. In general, the rougher the surface, the longer the roller nap should be. Synthetic brushes and rollers are generally used with latex or water-based paint. Oil-base and alkyd paints usually call for natural or synthetic brushes and rollers. Your paint dealer will guide you to the right combination of tools and materials for your project.
If your job requires several gallons of paint, avoid color variations from can to can by opening all of the cans and mixing, or “boxing,” them together in a separate container. While you work, use a paint stick to mix the paint frequently, giving it a good stir from the bottom up to prevent the pigments from settling.
To keep paint from building up in the paint can rim and spilling over the sides, use a hammer and nail to punch a small hole in the interior rim of the can, this will allow excess paint to drain back into the can.
