Colorlok is an engineered siding manufactured by Masonite. If you're thinking about painting your Colorlok siding, keep in mind that unlike wood, which is porous, Colorlok is not suited for adhesion, so you must properly condition it before painting it. Also remember to use acrylic latex primer and paint, which are engineered with elasticity that allows the finish to expand and contract with the siding as temperature fluctuates.

Clean the siding, using a pressure washer. Allow 2 to 4 hours of drying time after you wash it.
Ensure paint adhesion by sanding the siding with sandpaper until it feels slightly rough. If you do not abrade the siding before priming and painting, flaking will ultimately result.
Cover surfaces adjacent to the siding with professional painter's tape. Cover the areas beneath the siding with heavy-duty fabric drop cloths.
Coat the abraded siding with acrylic latex primer, using a roller stocked with a nap cover. Affix the roller to an extension pole if and when necessary. Use a nylon paintbrush to apply primer to areas of siding inaccessible to the roller. Allow 2 hours of drying time.
Clean the painting tools with water.
Coat the primed siding with acrylic latex paint, using the roller. Use the paintbrush to apply paint to areas of siding inaccessible to the roller. Allow 2 hours of drying time. Add a second coat if you can see the primer bleeding through.
