Hardie board is a popular choice for siding due to its durability and low maintenance requirements. However, over time, the paint on Hardie board may start to fade or peel. Painting your Hardie board is a great way to refresh its appearance and protect it from the elements. In this article, we will provide you with a step-by-step guide on how to paint Hardie board.

Materials You Will Need

Before you begin painting, gather the following materials:

  • Paintbrushes
  • Roller brushes
  • Paint tray
  • Exterior paint specifically formulated for Hardie board
  • Painter’s tape
  • Drop cloths or plastic sheets to protect surfaces
  • Sandpaper
  • Pressure washer or hose
  • Primer (if necessary)

Step 1: Clean the Hardie Board

Start by cleaning the Hardie board surface. Use a pressure washer or hose to remove any dirt, dust, or loose paint. Allow the surface to dry completely before moving on to the next step.

Step 2: Repair Any Damaged Areas

Inspect the Hardie board for any damaged areas, such as cracks or holes. Use a suitable filler or caulk to repair these areas. Follow the manufacturer’s instructions for the best results. Allow the filler or caulk to dry completely before proceeding.

Step 3: Sand the Surface

Use sandpaper to smooth out any rough areas or imperfections on the Hardie board. This will ensure a smooth and even paint application. Wipe away any sanding dust with a clean cloth.

Step 4: Apply Primer (if necessary)

If you are painting over a previously unpainted Hardie board or if the surface is stained, it is recommended to apply a primer before painting. Choose a primer that is compatible with Hardie board and follow the manufacturer’s instructions for application.

Step 5: Tape and Protect Surfaces

Use painter’s tape to protect any areas you don’t want to paint, such as windows, trim, or adjacent surfaces. Place drop cloths or plastic sheets on the ground to protect it from paint splatters and drips.

Step 6: Start Painting

Begin by cutting in with a paintbrush around the edges and corners of the Hardie board. Use long, even strokes and apply an even coat of paint. Once the edges are painted, use a roller brush to apply paint to the larger surface areas. Work in small sections and overlap each stroke to ensure even coverage.

Step 7: Apply Multiple Coats

Allow the first coat of paint to dry according to the paint manufacturer’s instructions. Apply additional coats as needed for full coverage. Two coats are usually sufficient, but depending on the color and condition of the Hardie board, you may need more.

Step 8: Remove Painter’s Tape

Once the final coat of paint is dry to the touch, carefully remove the painter’s tape. Remove it at a 45-degree angle to avoid peeling any paint off with it.

Step 9: Clean Up

Properly clean your brushes, rollers, and paint trays according to the paint manufacturer’s instructions. Dispose of any leftover paint or materials safely and responsibly.
