Preparations of door and surroundings

  1. Remove all the door fittings like door knob, letter plate etc. with screwdriver.
  2. Sand down the door thouroughly with sanding paper/sanding pad/ electric sanding tool, so that the paint will be able to adhere properly. Doors in good condition: 240 grit; doors with flaking paint need 120 grit sandpaper.
  3. If the door has cracks to be filled and smoothed out, now is the time to fix those with wood filler, putty knife and sanding paper.
  4. Remove all the dust with brush and/or vaccum cleaner.
  5. Now that the door is free of dust, wipe the door a cloth and white spirit to make. This is to get rid of residues of oil and grease.
  6. Mask off any areas you don’t want paint on, like remaining fittings and glass panel.
  7. Lay out the cardboard under the door. This prevents paint drops from ruining the floor.
  8. Leave the door half-open and block it with a door stop that goes under the door. This makes painting the door easy, and you don’t have to touch it while painting the door.

Paint the door like a pro

Finally, you can get the paint buckets and brush out and start the metamorphose of your door. Follow these steps, and your will feel like a door painting master:

  1. Shake and stir the undercoat well.
  2. Use your paint brush to cut in around edges and mouldings of the door.
  3. To paint the remaining areas of the door, fill an appropriate amount of undercoat pain the in the tray and wet the foam roller with it.
  4. Start to paint the rest of the door from the inside towards the outside, moving vertically and horizontally.
  5. Leave the undercoat paint to dry for the time indicated on the tin.
  6. Sand the dried undercoat sightly with a finer sanding paper so that the whole finish appears flat. Remove the sanding dust afterwards.
  7. Fetch the flat brush and the wood gloss paint tin in your chosen colour and stir it well.
  8. Use a new flat brush and use the same applying technique as earlier: start brushing on edges, roll the rest of the door, and leave to dry. Do not close the door
  9. Apply another coat of gloss if needed.

Finishing up

  1. After the paint has dried completey, check the door for flaws that might need redoing.
  2. Remove the masking tape.
  3. If you are satisfied with the result, pull the screw driver and screw on all the fittings and fixtures you removed earlier.

Tips:

  • Use thin layers of paint rather than one thick one. It will otherwise crack later, drip immediatley and look ugly.
  • Windy days are no good painting days, as they fill the air with dust, and yo don’t want dust on fresh paint.
