How to Paint Fiberglass Porch Columns
- 1). Clean the fiberglass porch columns using a pressure washer equipped with a low-pressure tip. Wait two to four hours for the columns to dry.
- 2). Promote adhesion by abrading the fiberglass porch columns with sandpaper. Scour the columns until they feel slightly coarse.
- 3). Cover areas adjacent to the columns with professional painter's tape. Cover the porch with heavy-duty fabric drop cloths.
- 4). Coat the sanded fiberglass porch columns with acrylic latex primer, using a roller stocked with a nap cover. Use a paintbrush, manufactured for use with water-based latex, to apply primer to areas of the porch columns inaccessible to the roller. Wait three hours for the primed columns to dry.
- 5). Wash the roller and brush with water.
- 6). Coat the primed fiberglass porch columns with acrylic latex paint. Apply the paint as you did the primer. Wait two hours for the painted columns to dry. Add an additional coat if you can see the base primer showing through.
