Painting interior doors can dramatically update your home’s look, but achieving a smooth, professional finish without brush marks requires the right technique and tools. This guide will walk you through the steps to paint interior doors flawlessly, avoiding the common problem of visible brush strokes.
Step 1: Gather Your Materials
Before you start, ensure you have the following tools and materials:
- High-quality paint (preferably latex or acrylic for interior doors)
- A foam roller and foam brush
- Sandpaper (220-grit and 320-grit)
- A microfiber cloth or tack cloth
- Painter’s tape
- Primer (if needed)
- Paint tray
- Drop cloths or protective coverings
Step 2: Prepare the Door
Proper preparation is key to achieving a smooth finish. Remove the door from its hinges and place it flat on a stable surface. This allows for easier, more even application of paint. If removing the door isn’t possible, you can still paint it while it’s hanging, but be mindful of drips.
Next, lightly sand the door with 220-grit sandpaper to smooth out any imperfections. After sanding, wipe the door clean with a microfiber cloth to remove dust and dirt. If your door has old, flaking paint or a glossy finish, you may need to apply a primer to ensure the new paint adheres properly.
Step 3: Tape and Protect Surrounding Areas
Use painter’s tape to protect any areas that shouldn’t be painted, such as hinges, door handles, or nearby walls. Lay down a drop cloth or protective covering beneath the door to catch any drips.
Step 4: Apply Primer (If Necessary)
If your door requires a primer, now is the time to apply it. Use a foam roller for large, flat areas and a foam brush for smaller or more detailed sections. Allow the primer to dry completely before sanding it lightly with 320-grit sandpaper. This step ensures the surface is smooth and ready for the paint application.
Step 5: Use a Foam Roller for a Smooth Finish
To avoid brush marks, use a high-density foam roller. Foam rollers create a smooth, even surface without leaving behind the texture that traditional paintbrushes can cause. Load the roller lightly with paint to avoid drips, and use long, even strokes. Start at the top of the door and work your way down, applying thin, even coats of paint.
Step 6: Use a Foam Brush for Edges and Details
For edges, corners, or raised panel details, switch to a foam brush. Foam brushes allow for precise application and help avoid brush strokes. Again, apply the paint in thin layers, and don’t overload the brush.
Step 7: Sand Between Coats
After the first coat of paint has dried, lightly sand the surface with 320-grit sandpaper to remove any tiny imperfections or uneven areas. Wipe the door clean with a tack cloth, and apply the second coat. Two coats are typically enough, but for darker colors, a third coat may be necessary.
Step 8: Allow the Paint to Dry Completely
Let the final coat of paint dry thoroughly before reattaching the door or handling it. This ensures that the surface remains smooth and doesn’t pick up fingerprints or other marks.
Conclusion
Painting interior doors without brush marks is achievable with the right preparation and technique. Using foam rollers and brushes, applying thin coats, and sanding between layers will help you create a flawless, professional finish. With a bit of patience, you can transform the look of your interior doors and enhance the overall style of your home.
