In this article, we’ll go over everything you need to know about painting Hardie board siding.

Choosing the Right Paint:

It’s essential to choose the right paint for your Hardie board siding. Look for a high-quality, 100% acrylic paint that’s designed specifically for fiber cement siding. Avoid using oil-based paints, as they can cause the siding to warp or buckle. It’s also a good idea to choose a lighter color, as darker colors can absorb more heat and cause the siding to expand and contract more rapidly.

Preparing the Surface:

Before you start painting, you need to make sure that the surface is clean and free of any dirt, grime, or mildew. Use a pressure washer or a stiff-bristled brush to remove any dirt or debris. If there’s any mildew present, use a mildew cleaner to remove it. Allow the surface to dry completely before painting.


Once the surface is clean and dry, you’ll need to apply a coat of primer. The primer will help the paint adhere better and provide a more even finish. Make sure to use a primer that’s designed for fiber cement siding.


When it comes to painting Hardie board siding, you have two options: spray or brush. Spraying is faster, but brushing can provide a more even and consistent finish. If you decide to spray, make sure to use a high-quality sprayer and wear protective gear, such as a mask and goggles.

Applying Multiple Coats:

In most cases, you’ll need to apply at least two coats of paint to achieve a solid and consistent finish. Make sure to follow the manufacturer’s instructions regarding drying times between coats.

Maintaining Your Painted Hardie Board Siding:

To keep your painted Hardie board siding looking great, it’s essential to maintain it properly. Regularly clean the surface with a mild detergent and water solution to remove any dirt or debris. Avoid using abrasive cleaners or tools that could damage the paint.


Painting Hardie board siding is an excellent way to refresh the look of your home and protect your siding from the elements. By following these tips and using the right products, you can achieve a beautiful and long-lasting finish.
