- Surface Preparation: Remove any loose or flaking paint using a scraper or wire brush and sand the surface to create a smooth, clean base for repainting.
- Repair Damaged Areas: Address any damage to the wood - such as rot or decay - before repainting. Use wood filler or epoxy putty to fill in cracks, holes, or gaps, and allow it to dry completely before sanding smooth.
- Prime the Surface: Apply a high-quality primer designed for wood surfaces when painting sash windows. The primer will help improve paint adhesion and seal the wood, providing a stable base for the topcoat.
- Choose the Right Paint: Select a top-quality exterior paint formulated for use on wood and suitable for the climate in your area. Consider factors such as durability, resistance to moisture and UV protection to ensure long-lasting results.
- Apply Multiple Coats: Apply several thin coats of paint rather than a single thick coat to achieve better coverage and durability. Allow each coat to dry completely before applying the next, following the manufacturer’s recommended drying times.
- Seal and Protect: Once the paint has fully cured, consider applying a clear sealant or topcoat to provide an extra layer of protection against moisture, UV rays, and other environmental factors.
- Regular Maintenance: Inspect them periodically for signs of damage or wear, and promptly touch up any areas of peeling or cracking paint.
