Painting sash windows is about more than just aesthetics, it’s crucial for the longevity and performance of the wood. The right paint will protect your windows from the elements, prevent rot, and ensure smooth operation. With so many options on the market, it’s essential to choose a paint that’s both durable and historically appropriate, especially if you’re working on a period property or listed building.
Sash windows are constantly exposed to the elements. Rain, wind, and sun can all take their toll on untreated or poorly painted wood. The right paint forms a protective barrier, helping prevent moisture from penetrating the timber, which can cause rot and structural issues.
Additionally, a good quality paint finish can:
Protect against UV damage, preventing wood from warping or cracking.
Keep windows operating smoothly, preventing sticking or jamming.
Preserve the period character of older buildings, especially if you’re working on a listed property.

When painting sash windows, it’s important to select the right type of paint for both durability and appearance.
Oil-Based Paints: Traditionally used for exterior woodwork, oil-based paints are highly durable and provide a glossy finish. However, they tend to yellow over time and are slower to dry.
Water-Based Paints: More eco-friendly and quicker to dry, modern water-based paints have excellent durability and can maintain their colour longer without yellowing. These paints are often recommended for sash windows today.
Acrylic Paints: Offering a flexible finish, acrylic paints are highly resistant to cracking and peeling, making them a great choice for exterior woodwork that expands and contracts with the weather.
Breathable Paints: For period or listed properties, breathable paints like lime-based or linseed oil paints are often required to allow moisture to escape from the wood, reducing the risk of damp and rot.
Choosing the right colour for your sash windows can enhance the character of your home and even boost its value. Many period properties look best when painted in traditional, muted colours such as whites, creams, and greys. In listed buildings, you may be required to use heritage colours that match the original palette of the building.
Common traditional colours include:
White: A classic choice that works well with nearly all architectural styles.
Cream or Off-White: Softer than bright white, providing a more period-appropriate look.
Sage Green or Muted Grey: Popular choices for Georgian or Victorian properties.
Black or Dark Brown: Often used for window sashes in Edwardian or early 20th-century homes.
If you’re working on a listed property, it’s essential to check with your local conservation officer to ensure the colours you choose are historically appropriate.
The key to a long-lasting, beautiful finish lies in the preparation and application of the paint. Here’s how to ensure a professional result:
Preparation: Sand the woodwork thoroughly, removing any old, flaking paint. Repair any damage to the timber before applying paint. It’s important to clean the surfaces and fill gaps or cracks to create a smooth base.
Primer: Always apply a primer to bare wood to create a stable surface for the topcoat. A primer will help the paint adhere better and last longer.
Undercoat: Applying one or two coats of undercoat helps create a durable, even finish. If you’re using oil-based paints, an oil-based undercoat is best, while water-based paints work well with acrylic or water-based undercoats.
Topcoat: The final layer should be applied with smooth, even strokes. When painting sash windows, use a brush suitable for detailed woodwork to avoid drips and streaks.
Drying Time: Allow each coat of paint to dry thoroughly before applying the next. This ensures a strong, durable finish.
To keep your painted sash windows looking their best, regular maintenance is key:
Inspect regularly for any signs of peeling or cracking and touch up any exposed areas to prevent moisture from entering the wood.
Repaint every 5-7 years, depending on the paint type and exposure to the elements.
Keep the windows clean and free from dust and debris to maintain smooth operation.
