Fiber cement siding is becoming increasingly popular with homeowners who like fiber cement’s combination of durability, appearance, and value. One difference between vinyl siding and fiber cement siding is that fiber cement siding more readily accepts paint. Here are some tips on how to paint your fiber cement siding:

Wash the Siding – For best results you’ll want to clean and prep the fiber cement siding so the paint will more readily adhere to the surface. Mix up a solution of 1/3 cup powdered laundry detergent and 2/3 cup powdered household cleaner in a gallon of water. Use a garden hose with a nozzle and a scrub brush to wash the siding from the bottom to the top. Avoid using a pressure washer as the more concentrated force of the water can actually damage your fiber cement siding. Make sure to fill in any cracks, gouges, or other damage at this time.

Prime the Siding – If you prime your fiber cement siding before painting you’ll get better results with less chance of the paint peeling or flaking over time. Use an exterior grade acrylic primer specifically designed for masonry or fiber cement siding. Apply the primer with smooth, even strokes, and allow it to dry before painting.

Use the Correct Paint - The best paint for fiber cement siding is a quality, exterior grade, acrylic latex. Check out the list of paints recommended for fiber cement siding at the James Hardie website or consult your local paint supplier.

By following these tips you can repaint your fiber cement siding to freshen its appearance or change its color. If you have vinyl siding be sure to read the post on painting vinyl siding instead.
