• Paint that matches the siding color

Step-by-Step Instructions

Hole Preparation

1. Clean the hole and surrounding area thoroughly with a scrub brush and water.
2. Using a sharp knife, remove any loose or damaged fibers around the hole.
3. If the hole is larger than 1 inch, create a small keyhole shape using a utility knife to ensure proper adhesion of the patching compound.

Patching

1. Fill the hole with the fiber cement patching compound using a putty knife.
2. Overfill the hole slightly to allow for shrinkage during drying.
3. Smooth the patch with the putty knife and remove any excess compound.

Sanding and Finishing

1. Allow the patch to dry thoroughly, following the manufacturer's instructions.
2. Sand the patch smooth using fine-grit sandpaper (120-grit or finer).
3. Clean the sanded area with a damp cloth to remove any dust.
4. Prime the patch to create a uniform surface for paint adhesion.
5. Paint the patched area with a high-quality paint that matches the siding color.
