Guide to painting a door
Interior doors are often overlooked, yet they play a central role in your home's aesthetic. Over time, daily wear and tear can leave them with scuffs, chips, and faded paint, dragging down the overall look of your rooms. Giving your internal doors a fresh coat of paint is a straightforward way to revive your interiors without the expense of replacing them.
Achieving a smooth, factory-quality finish requires systematic preparation and proper technique. Follow this step-by-step guide to paint your doors like a professional.
Key Takeaways
- Preparation is key: Proper sanding, filling, and cleaning ensure maximum paint adhesion and a smooth finish.
- Unscrew hardware & unhang: Taking the door off its hinges allows you to paint flat, eliminating drips and run marks.
- Use the correct paint: Choose durable water- or oil-based interior wood finishes rather than wall emulsion or exterior paints.
- Maintain structural elements: Ensure surrounding frames and skirting match for a unified look across your room.
Step 1: Preparation & Removing the Door
While you can paint a door while it hangs, removing it from its frame makes the job significantly easier and produces a much cleaner result.
- Remove the door: Unscrew the hinges from the frame, lift the door away, and lay it flat across two sawhorses or a protected workbench.
- Remove all hardware: Take off handles, latches, lock plates, and hinges. This saves time masking and guarantees clean edges around fixings.
- Inspect for damage: Fill any dents or gouges using a quality wood filler and a flexible filling knife. Leave it to dry completely.
Step 2: Sanding the Surface
Sanding creates a "key" for the new paint to grip onto, preventing peeling later on.
- Use a fine-grit sandpaper (around 180 to 220-grit) across the entire surface, working always in the direction of the wood grain.
- For panelled or decorative doors, use a flexible sanding block or folded paper to reach inside moulding grooves.
- Wipe down the entire door using a tack cloth or slightly damp microfibre cloth to remove all fine dust particles before painting.

Step 3: Priming the Door
Priming seals raw timber, covers old dark shades, and prevents moisture from warping the wood. If your door has been previously painted and is in good condition, a light sand and undercoat may suffice. However, bare wood or freshly filled spots require a dedicated primer.
| Door Condition | Recommended Primer / Undercoat | Drying Consideration |
|---|---|---|
| Bare Wood / New Timber | Wood Primer & Sealer | Allow 12–24 hours before topcoating |
| Previously Painted Wood | Water-Based or Solvent Undercoat | Lightly sand once dry to remove nibs |
| MDF Doors / Trim | Dedicated MDF Primer | Seals porous edges effectively |

Step 4: Applying the Paint
To avoid visible brush strokes, apply your paint in logical sections using a quality synthetic brush for edges and a short-pile foam roller for flat faces.
Painting Sequence for Doors
- Edges first: Paint the top, bottom, and side edges using long vertical strokes.
- Panels (if applicable): Paint recessed mouldings first, followed by the flat inner panels.
- Vertical & Horizontal Rails: Paint horizontal cross-rails next, finishing with the long vertical stiles.
Apply two thin coats rather than one heavy layer, allowing full drying time between applications. For wider home decorating guidance, explore our guide on how to choose paint colours to match your doors with your trim and walls.
Step 5: Reinstallation & Finishing Touches
Once the final coat has cured completely (refer to the paint manufacturer’s drying times):
- Reattach hardware: Screw the handles, latches, and hinges back into place. Replacing worn or tarnished handles with modern ironmongery is a quick way to enhance the finish.
- Rehang the door: Align the hinges with the original frame cutouts and secure the screws firmly without overtightening.
- Frame and Skirting: Ensure surrounding architraves and skirting boards are freshly painted to match. If your skirting boards need replacing, read our guide on how to fit a new skirting board.
