How to paint doors and windows

Paint doors and windows

This how to guide will show you how to paint your doors and windows to a professional standard.

Doors and windows are constructed using lengths of wood with grain patterns that inevitably run in different directions. To achieve an even, professional-looking finish, free from brush marks, you need to paint them in a sequence that takes account of the grain.

Think ahead when painting windows using oil-based paints, as they may take longer to dry than you expect. Or use water-based paint, which dries more quickly and releases much less odour and fumes.

Painting doors

If you are painting a new wooden door you will need to apply knot ting solution to any knots in the wood to prevent resin seeping through the new paint. If you are painting a stripped door this is not necessary as the surface will already be sealed. However, the door will need to be primed and undercoated.

Before starting, take off the door handles and wedge the door open. Keep the handle in your pocket in case the door is accidentally closed. Remove any dust using a soft brush and wipe the surface with a tack cloth.

Flush door

Divide the door into eight imaginary sections.

  • Start at the top left and work down from left to right.
