Painting interior doors is one of the easiest ways to give your home a fresh, updated look. Whether you’re renovating or simply looking to refresh a room, a new coat of paint on the doors can make a significant impact. However, painting doors comes with its own set of challenges. To achieve a professional finish and avoid potential pitfalls, it’s important to steer clear of common mistakes that many DIYers make. In this article, we’ll explore six common mistakes when painting interior doors and how to avoid them for a flawless result.

1. Skipping the Prep Work

One of the biggest mistakes people make when painting interior doors is rushing into the painting process without proper preparation. Just like painting walls or furniture, doors require thorough prep work to ensure a smooth and durable finish.

The Problem:

Failing to clean, sand, or prime the surface before painting can lead to a variety of issues. Dirt, grime, and oil can prevent the paint from adhering properly, while imperfections in the surface can become more noticeable once painted. Additionally, skipping primer on bare wood or stained doors can result in uneven coverage and poor adhesion.

The Solution:

Before you even think about opening that paint can, take the time to prep your doors properly:

  • Clean the doors: Wipe them down with a damp cloth and mild detergent to remove dust, dirt, and grease. Pay special attention to areas around the handles, as they tend to accumulate oils from frequent handling.
  • Sand the surface: Lightly sand the door with fine-grit sandpaper (220 grit works well) to create a smooth surface. This will help the paint adhere better and remove any previous finishes or imperfections.
  • Prime the door: If the door is unfinished wood, stained, or you’re changing from a dark color to a light one, applying a coat of primer is essential. This helps with adhesion, blocks stains, and provides a uniform base for the topcoat.

2. Using the Wrong Type of Paint

Choosing the wrong type of paint for your interior doors can lead to disappointing results. Doors are high-traffic areas that are touched frequently, meaning they need a durable finish that can withstand wear and tear.

The Problem:

Many DIYers mistakenly use standard wall paint, which may not provide the necessary durability for doors. Flat and matte paints, in particular, can scuff easily and may not hold up to constant handling.

The Solution:

Opt for a paint that is designed for high-traffic surfaces, such as doors and trim. Satin, semi-gloss, or gloss finishes are ideal for interior doors because they offer a more durable, washable surface that resists scuffing and fingerprints. Additionally, these finishes have a smoother texture, making them easier to clean and maintain.

If you’re unsure of which paint to use, ask for a product specifically designed for doors, trim, and molding at your local paint store. These products are formulated to provide a hard, long-lasting finish.

3. Leaving the Door on Its Hinges

Another common mistake when painting interior doors is leaving the door on its hinges while trying to paint it. This may seem like a time-saving shortcut, but it can lead to a less-than-professional finish.

The Problem:

Painting a door while it’s still hanging on its hinges can make it difficult to achieve smooth, even coverage, especially around the edges and along the bottom. Drips and uneven brush strokes are more likely to occur, and it can be challenging to paint the sides of the door without making a mess on the surrounding trim or walls.

The Solution:

Remove the door from its hinges before painting. While this adds a little extra work upfront, it will make the actual painting process much easier and result in a more professional finish. Here’s how:

  • Remove the door: Use a screwdriver or drill to remove the hinge pins and lift the door off the hinges. Lay the door flat on a pair of sawhorses or another stable, flat surface.
  • Paint the edges and sides: With the door removed, you can easily paint all sides, including the top, bottom, and edges, without worrying about drips or uneven coverage.
  • Reinstall the door: Once the paint is completely dry, reattach the door to its hinges.

4. Applying Too Much Paint at Once

Achieving a smooth, flawless finish on interior doors often requires multiple coats of paint. However, a common mistake is to try to get complete coverage in a single, thick coat.

The Problem:

Applying too much paint at once can lead to drips, sags, and an uneven finish. Thick coats of paint also take longer to dry and are more prone to visible brush strokes and roller marks. In some cases, heavy coats of paint can even cause the door to stick to the frame once reinstalled.

The Solution:

For the best results, apply multiple thin coats of paint rather than one thick coat. This approach allows each layer to dry properly and helps you build up a smooth, even finish. Here’s what to do:

  • Apply thin, even coats: Use a high-quality paintbrush or foam roller and apply the paint in thin, even layers. Start with the edges and detailed areas, then move on to the flat surfaces.
  • Let each coat dry: Allow the paint to dry completely between coats. This drying time will vary depending on the type of paint you’re using, so be sure to check the manufacturer’s recommendations.
  • Sand between coats: For an ultra-smooth finish, lightly sand the door with fine-grit sandpaper between coats to remove any imperfections, then wipe away the dust before applying the next layer.

5. Neglecting the Hardware

While the door is the main focus, neglecting the door hardware can detract from the overall look. Many DIYers make the mistake of painting around the hinges, knobs, and locks rather than removing or covering them properly.

The Problem:

Painting around hardware often results in messy edges and unsightly paint buildup. Over time, this paint can chip away, leaving exposed metal that detracts from the door’s appearance. Additionally, paint on hinges can cause the door to stick or squeak.

The Solution:

Remove or protect the hardware before painting:

  • Remove the hardware: The best option is to remove all hardware from the door, including knobs, locks, and hinges. This allows you to paint the door without any obstructions and ensures a clean finish.
  • Use painter’s tape: If removing the hardware isn’t feasible, use painter’s tape to carefully cover it and protect it from paint splatters. Be sure to press the tape down firmly to create a tight seal around the edges of the hardware.

6. Ignoring Drying and Curing Times

Patience is key when it comes to painting interior doors, especially when it comes to drying and curing times. Rushing to reattach the door or use it before the paint is fully dry can ruin all your hard work.

The Problem:

Doors that aren’t allowed to dry properly can stick to the door frame or jamb, leading to peeling or chipping paint. Additionally, if the paint hasn’t fully cured (which can take several days or even weeks), it will be more susceptible to damage from regular use.

The Solution:

Follow the recommended drying and curing times for your paint product. Here’s a general guide:

  • Drying time: Allow each coat of paint to dry fully before applying the next one. Most paints will dry to the touch in a few hours, but it’s best to wait at least 24 hours before handling the door.
  • Curing time: Even though the paint may feel dry, it can take several days or weeks to fully cure and harden. During this time, try to avoid heavy use of the door, such as slamming it or frequently opening and closing it.

Conclusion

Painting interior doors can be a simple yet impactful home improvement project, but it requires attention to detail and patience to achieve a professional result. By avoiding these six common mistakes—skipping the prep work, using the wrong paint, leaving the door on its hinges, applying too much paint, neglecting the hardware, and ignoring drying times—you can ensure that your interior doors look stunning and stay that way for years to come. Take your time, use the right materials, and follow the proper steps for a finish that will elevate your home’s interior.
