Then, the tools should be set aside, and the door’s panel shall be moistened with a sponge. Then you have to apply the first coat of paint, which must be of good quality. All that remains is to paint with the colour, giving broad brushstrokes.

Painting interior door in three easy steps:

  1. Take out any hardware. Sand the surface of the door. Use a sanding hold, such as sawhorses, to make it easier for you to work the panels’ edges and corners. Once the surface is smooth, dust and clean with a slightly moist sponge.
  2. Start by applying paint to the mouldings of the upper panels with a brush. Then paint the panels themselves using the roller before moving on to the panels below.
  3. Paint the centre part. Working from top to bottom, apply paint to the ties (horizontal elements). Finally, paint the outer studs.
  4. Allow the painted surface to dry and lightly sand before applying the second coat of paint. When the paint is dry, secure the hardware and walk up the door.

Before being repainted, your wood door should be perfectly prepared so that the new coat of paint adheres to the surface as best it can.

  • First, clean the encrusted stains with a soapy sponge, then add filler in cracks and other holes with wood pulp.
  • Then sand the entire surface of the door with sandpaper. You can use a hand-held electric sander if you feel comfortable with it.
  • Use a drop cloth to clear the door of dust and residue.

Don’t forget that you can use special priming after the sanding operation for optimal adhesion of the new coat of paint on your door. You’ll need to scrape the old paint gently before sanding if it’s in bad shape and flaking. If this is not enough to get rid of it, you will need to use a heat stripper or chemical stripper to help you quickly remove the old coat of paint.

If you choose to paint an internal door with moulding, start painting in the corners, then apply the paint in the moulding direction, making sure to pull it well. If the moulding is decorated, then use a round brush to dab the stain and cover the patterns. For more efficiency, you can opt to paint your single panel door using a foam roller. Start painting in the centre of the door and work your way up to the top. Reload the roller in paint before painting the bottom.

DIY tips for painting an interior door

There is no need to buy new doors when it is still possible to use those at home. Just apply some tricks to repaint them and make them look great.

What colours are best for interior doors?

It is possible to choose between different colours to paint an inner door. If the décor is white, it is advisable to select yellow-ish colours for the door. It accentuates the feeling of lightness. For more exoticism, it is recommended to opt for a door painted in salmon pink. It will stand out from the white colour of the walls. Blue, for its part, evokes depth, but it goes well with white. It is possible to make it more original by painting the door in two different colours.

Paint the door frame a different colour?

It is suggested to paint the door frame a different colour than the rest of the door to avoid monotony. For a wooden door, a white frame is to be highlighted. It enhances the door and maximizes the depth effect. Ideal for adding a decorative touch is to paint the door frame with two colours depending on the door’s face.

How do you paint a door without making a mess?

It is possible to paint an interior solid wood door without leaving brush marks. First of all, you have to choose good quality paint. It is recommended to apply a sublayer before laying an extra coat of paint. The paint should take time to dry. When painting the door, you should not put too much pressure on the roller. To avoid dripping, do not overload your foam roller. If traces of rollers persist, you can catch them at the time of the second coat of paint. For all styles of doors you want to paint or repaint, keep in mind that you will have to apply two coats of new paint anyway, letting the first one dry well before laying the second.

To paint a single panel door, we recommend that you visually divide your door into eight sections. Start at the top left angle with a 50-75 mm brush, crossing the brushstrokes and moving horizontally and then vertically. Do the same for each section, first painting the adjacent area and then moving to the lower divisions.
