Popcorn Ceiling and Crown Molding: Tips and Tricks

Popcorn ceilings, with their bumpy, textured appearance, were a staple in homes built decades ago. While some homeowners love their unique character, others find them outdated and yearn for a smoother, more modern look. If you have a popcorn ceiling, you might wonder if adding crown molding – that elegant trim where the ceiling meets the wall – is possible. The good news is, it absolutely is! It takes some extra care, but the results can drastically transform your space. In this blog, we’ll give key points for your popcorn ceiling and crown molding project.

What is Crown Molding and its Purpose?

Crown molding is a decorative architectural feature installed at the junction where walls meet the ceiling. It typically has a sculpted or detailed profile, adding a polished finish to the room.

Crown molding purpose is to add:

  • Aesthetics: Enhances visual appeal, making rooms look more elegant and finished. It can create the illusion of taller ceilings.
  • Style Definition: Different styles of crown molding enhance different décor themes: grand and ornate for traditional, sleek and simple for modern.
  • Practicality: Hides inconsistencies where walls and ceilings meet, covering uneven joins and making painting easier.

Should You Do It? Considerations 

Cost vs. Benefit

Crown molding itself can range from budget-friendly to quite expensive depending on the material, size, and intricacy of the design. Factor in additional expenses like adhesive, caulk, paint, and any essential tools you might need to purchase. If you plan to hire a professional, labor costs will significantly increase the price. Consider the potential return on this investment: will adding crown molding truly enhance the room’s appearance and increase your enjoyment of the space? It may even add a little to your home’s resale value down the line.

Style Preference

Crown molding can add a touch of elegance and sophistication to any room, but it’s essential to choose a style that complements your overall décor. Traditional homes often feature ornate crown molding with elaborate details, while modern spaces benefit from simpler profiles with clean lines. If your décor is eclectic, crown molding can be used to tie disparate elements together. Take some time to browse images of different crown molding styles to find what appeals to you.

Ceiling Condition

Before committing to a crown molding project, thoroughly assess your popcorn ceiling. Small imperfections are easily concealed by the molding and caulk. However, if there are areas where the popcorn texture is significantly damaged, loose, or flaking, you’ll need to address those first. This might involve scraping and patching, which will add both time and cost to the project. If the ceiling condition is poor, you’ll need to decide whether the repairs and subsequent installation are worth the effort.

Tools and Materials

Ensure you have the proper tools and material for the popcorn ceiling and crown molding project. Here’s what you’ll need:

  • Miter Saw: This is crucial for making precise angled cuts, particularly for corners. A compound miter saw offers flexibility for different angles.
  • Level: Ensure a straight installation by using a level throughout the process.
  • Caulk Gun: For applying caulk to fill gaps and create a seamless finish.
  • Tape Measure Accurate measurements are vital for correctly sized molding pieces.
  • Pencil: For marking your walls where the molding will go.
  • Stud Finder (optional): If you plan to use finishing nails along with adhesive, a stud finder will help you locate the studs for secure nailing.
  • Safety Glasses: Protect your eyes from sawdust and debris.
  • Painter’s Tape: Use this to protect the ceiling and walls during painting.

Crown Molding Types: Pros and Cons for Popcorn Ceilings

  • Wood:
    • Pros: Classic look, durable, can be stained or painted, many style options
    • Cons: Heavier, more difficult to cut, most expensive
  • MDF (Medium-Density Fiberboard):
    • Pros: Budget-friendly, easy to work with, comes pre-primed
    • Cons: Susceptible to moisture damage, less intricate designs available
  • Polystyrene:
    • Pros: Super lightweight, easiest to cut and install, very affordable
    • Cons: Can look less high-end, may not suit ornate styles

Popcorn Ceiling Consideration: Polystyrene is often the best choice for popcorn ceilings due to its lightweight nature, making it easier to work with and less likely to stress the textured ceiling.

Adhesives and Finishing

  • Construction Adhesive: Choose an adhesive explicitly formulated for attaching your chosen molding material to the ceiling. Look for one designed for uneven surfaces if you have a popcorn texture.
  • Paintable Caulk: Choose a flexible caulk that will expand and contract to fill gaps between the molding, wall, and ceiling.
  • Paint: Select a paint that complements your room’s color scheme. Semi-gloss or satin finishes tend to work best for crown molding. If painting over popcorn, choose a roller with a longer nap to ensure proper coverage of the texture.

Additional Notes:

  • Consider the size and style of your room when choosing crown molding. Larger rooms can handle wider, more elaborate molding, while smaller spaces do better with simpler profiles.
  • Always wear safety goggles and a mask when cutting molding.

Installation Steps 


Start by clearing furniture from the room to give yourself ample workspace, or cover your furniture thoroughly with drop cloths. Protect your floors with drop cloths as well. If you want the cleanest-looking finished product, consider scraping away the popcorn texture in the area where the molding will be installed. If you’re keeping the popcorn ceiling, be aware of the extra challenges you may face during installation. Next, take careful measurements of your room’s perimeter, adding a bit extra to account for waste from cuts. Using those measurements and a level, mark the wall where the bottom edge of your crown molding will sit, creating a guide for your installation.

Cutting the Molding

A miter saw is essential for achieving the precise angled cuts required for proper crown molding installation. For inside corners, where two wall pieces meet, you’ll need to cut each adjoining piece of molding at a 45-degree angle so they form a seamless 90-degree angle when placed together. Outside corners are similar but require the 45-degree angle cuts to be made in the opposite direction to fit together correctly.


Apply a construction adhesive designed for your chosen molding material to the back of the molding in a zigzag pattern. Carefully and firmly press the molding to the wall, following the guide line you marked earlier. For added security, especially with heavier wood molding, consider using finishing nails through the molding into the wall framing.


Once the molding is installed, carefully inspect for any gaps between the molding and the ceiling or walls. Fill these gaps (along with any visible nail holes) with a paintable caulk. Use a damp finger to smooth the caulk line for a clean appearance. Finally, apply several coats of paint to your crown molding, allowing complete drying time between coats. Choose a paint color that either complements your walls or creates a pleasing contrast.

Troubleshooting and Alternatives

  • Uneven Gaps: Popcorn ceilings can create larger and more noticeable gaps between the molding and the ceiling or wall. To fill these seamlessly, apply a thicker bead of caulk. You may even need to layer the caulk, allowing each layer to dry before adding the next. This gives a smoother and fuller appearance to the seam.
  • Painting Challenges: The bumpy texture of popcorn ceilings can make it difficult to achieve a clean finish when painting your crown molding. Use a paint roller with a slightly longer nap to ensure the paint reaches into all the nooks and crannies of the texture. Be prepared to apply several thin coats of paint, allowing them to dry fully between each coat for optimal coverage.
  • Alternatives: If traditional crown molding feels too complicated for your popcorn ceiling, there are still ways to add architectural interest. Consider simpler trim options like flat stock molding, which is easier to install and blends more easily with uneven surfaces. It adds a polished look without the challenge of angled cuts.


Adding crown molding can significantly upgrade a room with a popcorn ceiling. It instantly introduces elegance, helps disguise the dated nature of the ceiling, and adds architectural detail that elevates the entire space. While it does present some unique challenges due to the uneven ceiling texture, this project is definitely achievable with proper preparation, patience, and the right techniques.
