Revitalize Your Home: A Comprehensive Guide to Painting Interior Doors


Interior doors are an integral part of your home’s design, often overlooked when it comes to adding a splash of color or freshening up the d├ęcor. A well-painted door can breathe new life into a room and contribute to the overall aesthetic. This comprehensive guide will walk you through the steps to paint your interior doors like a pro, ensuring a smooth and lasting finish.

Materials and Tools You’ll Need:

  1. Interior paint (water-based or oil-based)
  2. Primer (optional but recommended)
  3. Sandpaper (120 and 220-grit)
  4. Painter’s tape
  5. Drop cloth or plastic sheeting
  6. Paint tray
  7. Paint roller (small, foam or microfiber)
  8. Paintbrush (angled or flat, 2-inch)
  9. Screwdriver
  10. Clean cloth or tack cloth

Step 1: Choose the Right Paint

Selecting the right paint is crucial for a long-lasting and professional-looking finish. Water-based (latex) paint is the most popular choice for interior doors due to its low odor, quick drying time, and easy clean-up. Oil-based paint is more durable, but it takes longer to dry and has a stronger odor. Whichever type you choose, ensure that it’s formulated for use on doors and trim.

Step 2: Prepare the Door

Remove the door from its hinges using a screwdriver and lay it on a flat, protected surface. Remove all hardware, such as knobs, latches, and strike plates. Use painter’s tape to cover any areas you don’t want to paint, like windows or glass inserts.

Step 3: Clean and Sand the Door

Clean the door with a mild soap and water solution, then rinse and allow it to dry completely. Sand the door using 120-grit sandpaper to remove any old paint, imperfections, or glossy surfaces. After sanding, wipe the door with a clean cloth or tack cloth to remove dust.

Step 4: Prime the Door (Optional)

Although not always necessary, applying a primer can help create a smooth and even surface for the paint to adhere to. This is especially important if you’re painting over a dark color or bare wood. Choose a primer that is compatible with your paint type and follow the manufacturer’s instructions for application and drying time.

Step 5: Paint the Door

Pour your chosen paint into a paint tray. Start by cutting in the edges and any recessed or raised panels with the paintbrush. Use the paint roller to apply paint to the flat surfaces of the door, working in a vertical direction. Apply thin, even coats to prevent drips and ensure a smooth finish. Allow the paint to dry for the recommended time, then apply a second coat if necessary.

Step 6: Reinstall the Hardware and Door

Once the paint is completely dry, carefully remove the painter’s tape and reinstall the hardware. Reattach the door to its hinges and enjoy your freshly painted interior door.


Painting interior doors is a simple and cost-effective way to update your home’s appearance. With the right tools, materials, and attention to detail, you can achieve a professional-looking finish that will make your doors stand out and complement your home’s design.
