How to paint timber window frames

Overview

Window frames may not be a dominating factor in your home’s design, but how they look can affect any space dramatically. Peeling paint on a window frame can bring the whole feel of the room down, standing out against fresh walls and exposing the timber underneath to potential damage. Luckily, there’s a super-easy fix!

This simple painting project will rejuvenate any wooden window frames, giving them a new lease on life and ensuring their longevity. The key is in the preparation and quality of materials – take the time to prepare your frames properly and use the best paint available to give your timber window frames the best chance at surviving whatever is thrown at them. Check out our guide on how to choose the right paint finish.

The other element to consider before starting this D.I.Y. project is which colour to paint your frames! If you already have a feature statement, consider a neutral or white tone, as it will brighten the space without clashing with anything else. However, if you’re looking to make a statement, or want to draw attention to your windows, opt for a shade that’s slightly lighter or darker than your walls.

Steps

1Clean the window frames

Before you make any changes to your timber windows, it’s important to prepare the surfaces. Using a brush, wipe away all dust and dirt.

5Paint your windows

Paint your first coat of paint, using a paintbrush. Leave to dry. Repeat with a second coat and leave to dry. If you have a spillage, not to worry just use your rag to clean it up.

Health & Safety

Asbestos, lead-based paints and copper chromium arsenic (CCA) treated timber are health hazards you need to look out for when renovating older homes. These substances can easily be disturbed when renovating and exposure to them can cause a range of life-threatening diseases and conditions including cancer. For information on the dangers of asbestos, lead-based paint and CCA treated timber and tips for dealing with these materials contact your local council's Environmental Health Officer or visit our Health & Safety page.
