  • 1 Remove fittings with a screwdriver.
  • 2 Sand down the door to give the undercoat or gloss a sound surface to adhere to. Dust down door and wipe with white spirits.
  • 3 Mask off any areas you do not want to have paint on e.g. windows or fittings you are unable to remove.
  • 4 Place a dust sheet under the door to protect the floor from any paint splatter. If there are any small holes or cracks in the door fill these with wood filler at this stage. Additional information: If you are applying a similar gloss colour, you could lightly sand the existing paint to attain ‘a key’ for the gloss paint to adhere to, but if you are changing the colour totally it is recommended that you apply an undercoat first to give a better finish to the gloss colour. If you were applying to a bare wood door you would need to apply a primer first, then an undercoat and then your gloss paint.
  • 5 Put on rubber gloves, and mix the can of undercoat. Use a paint brush to cut in around the mouldings and edges with the paint.
  • 6 To paint the rest of the door, pour undercoat into mini roller tray and use a mini foam roller for quicker coverage. Start with the inner verticals and horizontals. Then paint the outer verticals, then paint the top and bottom horizontals and finally the panels. Leave to dry for time indicated in the instructions.
  • 7 Before applying the top coat, sand the door gently and dust off.
  • 8 Shake the can of gloss and use a brush to cut in using the same method as the undercoat.
  • 9 Then use a roller to paint the rest of the door, again using the same method as the undercoat. Leave to dry. Top Tip: Avoid painting on a windy day as dust particles may affect your finish.
  • 10 Apply second coat if needed. Put back on fixtures and fittings and remove any masking tape and the dust sheet.
