How to repaint sash windows
Sash windows bring timeless character and charm to any home, but tired or flaking paint can dull their beauty. With a little prep and the right paint, you can breathe new life into them, inside or out.
Preparation
Start by giving your windows a thorough clean and inspect the frames for any damage. Sand back old, flaky paint and fill any cracks or gaps with a good wood filler. Once dry, sand again to smooth the surface. Proper preparation helps your paint adhere better and gives you a flawless finish.

Next, mask off the glass panes and surrounding areas with painter’s tape for neat lines. If your sash windows are functional, open them up and paint the top sash first. Be careful to avoid painting the sliding channels – this helps prevent sticking once dry.
Painting sash windows
For interior sash windows, reach for Frenchic Trim Paint. With its subtle satin sheen and low-VOC, water-based formula, it’s ideal for indoor spaces and safe for every room. For exterior frames, our Al Fresco range is the perfect partner. Weatherproof, UV-resistant and self-sealing, it’s tough enough to face the elements while looking fabulous.
Apply with a high-quality brush. Follow coverage guidance on the tin to ensure paint doesn’t go on too thin or too thick, and let each coat dry thoroughly. Remove the masking tape while the final coat is still tacky to get sharp, clean edges.
