Skipping the Prep Work
As of September 2026, I’ve seen so many DIYers skip the prep work, assuming that chalk paint will magically stick to any surface. The truth is, chalk paint works best on clean, dry surfaces that have been sanded lightly. If you skip sanding, especially on wood that has a glossy finish, the paint will not adhere properly, leading to peeling or flaking over time.
In one of my first attempts, I painted a piece of furniture without sanding, and the paint came off within a few weeks. It was a costly mistake, but it taught me the importance of preparation. I now always spend at least 15 minutes sanding the surface before painting, even if it seems like a small step.
Sanding also helps to create a better surface for the paint to grip onto. It removes any old finishes, dirt, or oils that may be on the surface. If you’re working on a surface that has a glossy finish, like a painted cabinet, you should sand it with 220-grit sandpaper until it’s slightly rough. This will help the chalk paint adhere better.
Use 220-grit sandpaper to roughen up the surface. Wipe it clean with a damp cloth before applying paint for the best results.[1]

Not Using a Primer or Sealer
I used to skip the primer step, thinking that chalk paint was self-sufficient. But I quickly learned that without a primer, the paint can look uneven, especially on dark or porous surfaces. A primer helps the paint stick better and ensures a more even finish.
I once painted a set of drawers without using a primer, and the finish was patchy and inconsistent. I had to repaint the entire set, which was both time-consuming and frustrating. Now, I always use a white primer, especially on dark wood, to create a uniform base for the paint.
A sealer is also important, as it protects the paint from scratches and wear. I recommend using a water-based sealer that’s suitable for the surface you’re working on. This will make your project more durable and extend its lifespan.
A primer isn’t just a step — it’s an investment in quality and longevity.

Using the Wrong Tools
I made the mistake of using a regular brush for chalk paint, and it left streaks and uneven coverage. Chalk paint works best with a high-quality brush that has soft bristles and a flat shape. Using the wrong brush can lead to a poor finish that requires multiple coats to fix.
I now use a 2-inch flat brush made for chalk paint, and it makes a world of difference. It allows for even coverage and a smooth finish. I also use a foam brush for smaller details, like trim or corners, where I need more precision.
Investing in the right tools can save you time and money in the long run. High-quality brushes may cost a bit more, but they make the process much easier and the final result much better.
Use a 2-inch flat brush for large areas and a foam brush for smaller details. This ensures even coverage and a professional finish.

Overworking the Paint
One of the most common mistakes I see is people overworking the paint, either by applying too many coats or by using too much pressure when painting. This can lead to a dull, uneven finish that looks unprofessional.
I once painted a piece of furniture and applied too much pressure, which caused the paint to streak and not adhere properly. I had to repaint the entire piece to fix the issue. Now, I apply the paint in thin, even strokes and let each coat dry before applying the next.
Another tip is to avoid over-brushing the paint. If you notice the paint starting to look dull or streaky, stop and let it dry. Chalk paint is designed to be used in thin, even coats, and overworking it can lead to an inferior finish.

Ignoring Drying Times
I once rushed through a project and didn’t wait for the paint to dry properly between coats. The result was a smudged, uneven finish that I had to repaint. This was a valuable lesson in the importance of patience and proper drying times.
I now make sure to let each coat dry completely before applying the next one. Chalk paint typically takes 1-2 hours to dry between coats, depending on the humidity. In a dry, well-ventilated room, it dries faster, while in a humid environment, it may take longer.
Ignoring drying times can also lead to smudges, especially if you’re working on a surface that’s in a high-traffic area. If you’re painting a piece of furniture that will be used right away, make sure to let it dry fully and apply a sealer afterward.

Underestimating the Impact of Humidity on Chalk Paint Adhesion
To avoid the frustration of dealing with humidity, I now always test a small area first. I apply a small patch of paint and wait 24 hours to see if it holds. If it starts to lift or feel moist, I know the environment is not ideal. I've also learned to paint in well-ventilated areas and avoid painting during the early morning when humidity tends to be highest. By taking these steps, I've been able to achieve long-lasting results even in more challenging conditions.
Neglecting the Importance of Sanding Between Coats
In one project, I painted an old bookcase with multiple coats of chalk paint and skipped sanding. The final result was lumpy and inconsistent, and I had to repaint the entire piece. Since then, I’ve made it a point to sand between every coat — even if it takes extra time. It’s a small step that makes a big difference in the final outcome. I’ve also started using a fine sanding sponge for curved or intricate surfaces, which makes the process easier and more efficient. If you want a smooth, professional-looking finish, don’t skip this step — it’s well worth the extra effort.
Overlooking the Importance of Proper Ventilation
Proper ventilation is often overlooked but can significantly impact the success of your chalk painting project.
I once painted an entire set of furniture in a small, closed room and ended up with a musty smell that clung to the pieces for weeks. The lack of airflow allowed the paint to trap moisture, which led to a dull finish and a slow drying time. Always work in a well-ventilated space, ideally with open windows or a fan running. This not only helps the paint dry faster but also improves the overall quality of the finish. It also makes the experience more pleasant, especially if you're working with multiple pieces or in a confined area.
Ventilation is especially important when using chalk paint indoors. The chalky texture can create fine dust that settles on the surface if not properly aired out. I've found that using a box fan pointed at the work area helps circulate air and prevents the paint from becoming too tacky. Even if you're working outside, be mindful of wind direction to avoid dust settling on freshly painted surfaces. Good airflow ensures even drying and helps avoid the formation of bubbles or uneven spots.
In my experience, poor ventilation can also lead to an increased risk of mold and mildew, particularly in damp environments. I once painted a set of kitchen cabinets in a humid bathroom, and without proper ventilation, the paint started to yellow and bubble after just a few days. Always ensure the space is dry before beginning, and if possible, paint during the day when natural light and airflow are strongest. Taking these steps can make a noticeable difference in the final result and longevity of your chalk-painted pieces.
