Painting Different Types of Hollow Core Interior Doors
When it comes to hollow core interior doors, there are two main types: panel doors and flat doors. Both options offer their own unique advantages, and understanding their differences will enable you to make an informed decision when painting your doors.
Panel Hollow Core Doors
Panel doors are the more traditional choice, featuring a series of raised panels separated by rails and stiles. These doors can have a variety of panel patterns, ranging from a simple two-panel design to a more elaborate six-panel layout.
The panels can be either rectangular or curved, adding a touch of elegance to your space. Panel doors are typically made of fiberboard or medium-density fiberboard (MDF), which not only keeps them lightweight but also provides an easy surface for painting.
Flat Hollow Core Doors
Flat doors have a clean, minimalist aesthetic, with a smooth, flat surface devoid of any panels or intricate details. These doors are well-suited for modern or contemporary interiors, as their simplicity helps to maintain a streamlined appearance. Like panel doors, flat hollow core doors are also usually made from fiberboard or MDF.

Materials and Tools Required To Paint Your Hollow Core Door
Before you begin painting your hollow core interior doors, gather all the necessary materials and tools.
To ensure a smooth and professional finish, you’ll need the following:
- Sandpaper: A medium-grit (around 220) sandpaper is ideal for sanding the door and ensuring a smooth surface.
- Tack cloth: Use this to remove any dust or debris from the sanding process.
- Painter’s tape: This will protect hardware and any other areas you don’t want to paint.
- Putty knife: Required for applying wood filler and smoothing out any imperfections on the door’s surface.
- Wood filler: Use this to repair any cracks and even out rough spots on the door.
- Stain-blocking primer: A must-have for hollow core doors to ensure a smooth, even paint application.
- Paint: Choose a latex-based semi-gloss paint for a durable and attractive finish.
- Paintbrush: While a regular paintbrush is suitable for small and detailed areas, a high-quality foam roller is the preferred choice for the larger door surface.
- Foam roller: Helps you apply paint smoothly and uniformly on the door’s surface.
- Screwdriver: You’ll need this to remove and later reinstall the door’s hardware, such as knobs and hinges.
- Door hardware: Have new door knobs and door hinges ready to install after painting.
Preparing the Door
Removing Hardware and Hinges
Before starting the painting process, it’s essential to remove all the door hardware, including doorknobs, hinges, and any decorative molding. Place a drop cloth on the floor beneath the door to protect your flooring from dust and debris.
After removing the hardware, set the door on sawhorses for easy access and painting.
Sanding and Repairing the Door
Examine the door for any minor damages, such as cracks or chips in the veneer. If you find any, use wood filler to repair them. Apply the wood filler with a putty knife and allow it to dry according to the manufacturer’s instructions.
Next, sand the door using a sanding sponge. Start with medium-grit sandpaper and work your way up to fine-grit sandpaper. This process will smoothen the surface and help the primer and paint adhere better.
Be sure to sand in the direction of the wood grain, and pay extra attention to areas around the repaired cracks or chips.
Remember to wipe down the door with a damp cloth to remove any dust or debris after sanding. Allow the surface to dry completely before moving on to the next step.
Applying Primer to the Door
Priming the door is crucial for achieving a smooth, even finish. Use a stain-blocking primer suitable for the door’s material, and apply it with a brush or roller. Cover the entire surface, including any edges and recessed areas.
Allow the primer to dry according to the manufacturer’s instructions before proceeding with the paint application.

Tips and Tricks for a Professional Finish
- Choosing the right paint: For the best results, use latex paint with a semi-gloss finish. This type of paint will provide a smooth, easy-to-clean surface, and semi-gloss offers enough shine to make the door stand out.
- Dark colours: If you’re opting for a dark color, keep in mind that it might require more coats for even coverage. Be patient and allow each coat to dry properly before moving on to the next.
- Paint Brushes and Rollers: Use a high-quality paint brush or foam roller for a smooth, even finish without brush marks. Foam rollers are particularly useful for large, flat surfaces, while a paint brush is better for raised panels and vertical stiles.
- Paint Application: Start by painting the raised panels and vertical stiles first, and then proceed to the rest of the door. This will prevent paint drips and ensure a smooth finish.
- Eliminating Paint Drips: To avoid paint drips, do not overload your brush or roller with paint. If you notice any drips forming, quickly smooth them out with your brush or roller before they have a chance to dry.
Reinstalling Hardware and Hinges
Once your door is painted and dry, carefully reinstall the hardware and hinges.
