When it comes to painting asphalt siding, you have to be careful who you listen to. Many people recommend that asphalt siding be painted with a heavy-duty rubberized, elastomeric paint to ensure a long-lasting finish. This can be disastrous. Because elastomeric paint seals everything out and in, it is not what professionals call a breathable coating. This means that moisture is allowed to build up underneath the siding, which eventually causes the underlying wood to rot, mold or mildew. If you need to paint asphalt siding, you need to know what kind of materials to use, or you may end up causing costly damage to your home.
Wash away dust and dirt using a pressure washer. Allow the surface to dry completely.
Fill a 5-gallon bucket halfway with exterior latex primer. Attach the nap cover to the frame.
Apply primer to the asphalt siding using the roller. Roll vertically, moving left to right.
Apply primer to the any tight areas you couldn't reach with the roller using the paintbrush.
Clean each painting tool using water.
Apply exterior acrylic latex paint in the same manner as you did the primer in steps 2, 3 and 4.
