How Do I Paint Exterior Wooden Windows?

Prepare the wood

You need to prepare the surface before you paint it.

For bare wood, use 120 grit sandpaper to sand in the direction of the woodgrain and smooth out the surface. This helps the paint stick to the surface.

Once the dust has settled, wipe down your door with white spirit.

If you spot any holes of cracks, fill them in and cover knots with knot blocker to stop them showing through your new paint.

For previously painted windows in a good condition, lightly sand it with 240 grit sandpaper. Once the dust has settled, wipe the surface down with white spirit.

For wooden windows with flaking, cracked or peeling paint, use 120 grit sandpaper to sand away the paint down to the bare wood. We recommend using an electric sander to make a quick job of it but you could use a flat scraper. Once the dust has settled, wipe it away with white spirit.

Before priming, clean the window frames using Tikkurila's Cleaning Agent to remove any grime and dirt.

Prime the wood

Apply your primer to the window and leave it to dry. Make sure you cover it thoroughly so your paint sticks consistently. We recommend our Ultra Primer
