Can You Paint Hardie Board?

Hardie Board is made from a mix of cement, sand, and cellulose fibers, creating a sturdy and weather-resistant material. It’s designed to withstand harsh environmental conditions, making it an ideal choice for exterior siding. Despite its tough exterior, Hardie Board is surprisingly paint-friendly. With the right preparation and materials, painting Hardie Board can be a successful DIY project that elevates the look of your home.

What is Hardie Board?

Hardie Board is a brand name for fiber-cement siding produced by James Hardie Building Products. It’s a composite material made from cement, sand, and cellulose fibers, which creates a durable and long-lasting product. Hardie Board is known for its resilience against weathering, rot, and fire, making it a popular choice for exterior home siding.

This type of siding replicates the look of wood but without the susceptibility to decay and termite damage. Its composition allows it to withstand extreme weather conditions, from harsh sun to freezing temperatures, without warping or cracking. Hardie Board comes in various styles and textures, giving homeowners a range of aesthetic choices for their exteriors.

Can You Paint Hardie Board

Yes, the Hardie Board can be painted, which is one of its appealing features. The board’s surface allows for excellent paint adhesion, making it possible to customize its color to fit your home’s design. Painting Hardie Board not only enhances its aesthetic appeal but also adds an extra layer of protection against the elements.

Before painting, it’s important to ensure the Hardie Board is clean and free from any dust or debris. If the siding is newly installed, it’s advisable to wait for it to cure before painting. For previously painted Hardie Board, inspect the surface for any chipping or peeling paint and address these areas during the preparation phase.

Best Paints for Hardie Board

Acrylic Paints:

Acrylic latex paint is highly recommended for Hardie Board due to its flexibility and durability. It adheres well to the surface and can expand and contract with the siding, reducing the likelihood of cracking or peeling.

Latex Paints:

Latex paint is another suitable choice for Hardie Board. It offers good coverage, is easy to work with, and dries quickly. Additionally, it’s resistant to mildew and fading, which is beneficial for exterior applications.

Paint Brand Recommendations:

For best results, use high-quality exterior paints from reputable brands like Sherwin-Williams, Benjamin Moore, or Behr. These brands offer paints specifically formulated for use on exterior surfaces like Hardie Board, ensuring long-lasting finishes and durability.

How to Paint Hardie Board


  • Cleaning: The first step in preparing Hardie Board for painting is thorough cleaning. Remove any dirt, dust, or mildew from the surface. This can be done using a mild detergent mixed with water. Use a soft brush or cloth to gently scrub the surface. For areas with mildew, a solution of water and bleach can be effective. Rin’t the surface well with clean water after cleaning.
  • Repairs: Inspect the Hardie Board for any damages or cracks. It’s essential to repair these before painting. Small cracks can be filled with an exterior-grade filler. Follow the filler’s instructions for application and drying time. Ensure that all repairs are smooth and flush with the rest of the siding for a uniform appearance.


  • Select a primer that is specifically formulated for exterior use and is compatible with fiber-cement siding. A good primer will improve paint adhesion and increase the longevity of the paint job.
  • Apply the primer evenly across the Hardie Board. You can use a brush, roller, or sprayer, depending on the size of the area and your comfort level with each tool. Ensure complete coverage, especially in repaired areas. Allow the primer to dry as per the manufacturer’s instructions before proceeding to paint.


  • When it comes to painting the Hardie Board, you have the option of using a brush, roller, or sprayer. Each tool has its benefits: brushes provide precision, rollers cover large areas quickly, and sprayers offer a smooth finish.
  • Apply the paint in sections. Work systematically from one end to the other. When using a brush or roller, maintain a wet edge; this means overlapping the previous section slightly before the paint dries to avoid lap marks.
  • Apply the paint evenly and ensure that all surfaces are covered. If using a roller, choose one with a nap suitable for the texture of your Hardie Board. For spraying, follow the equipment’s guidelines for the best results.


  • Allow the paint to dry completely between coats. The drying time can vary depending on the type of paint used, the weather conditions, and the thickness of the application. Check the paint can for the manufacturer’s recommended drying time.
  • If a second coat is required, ensure the first coat is completely dry before applying the next. This will prevent smudging and ensure the layers bond well.

How to Maintain Hardie Board After Painting

Maintaining your painted Hardie Board ensures it stays looking good and lasts longer:

Use a soft brush with some mild soap and water to gently scrub off any dirt. If there are tough stains, you can use cleaners that stop mildew from growing. Rinse off the soap with water when you’re done cleaning. Besides cleaning, you should also check the siding regularly to see if there are any chips, cracks, or other signs of damage. If you find small damages, fix them right away by using some paint that matches the color of your Hardie Board.

This stops bigger problems from happening like water getting into the siding. It’s best not to use a pressure washer for cleaning because it can be too harsh and might damage the paint or the siding.
