You may have painted a door, a wall, or even an entire room with chalkboard paint and later decided you want a different finish. Painting over chalkboard paint is entirely doable, but it requires a few specific steps and the right materials to get a smooth, lasting result.
Because chalkboard paint creates a dark, slightly textured surface, simply applying one coat of standard wall paint usually won’t hide it. With proper preparation and the right primer, though, you can restore the surface to a regular painted finish without the chalkboard texture or ghosting showing through.
1. Clean the Surface Thoroughly
Before any sanding or painting, remove all chalk residue. Wipe the surface with a damp cloth and a mild cleaner to lift dust and chalk dust, then let it dry completely. Grease or lingering chalk marks can interfere with primer and paint adhesion, so take care to get the surface as clean as possible.
2. Sand to Create a Key
Light sanding is the next step. Use medium-grit sandpaper to scuff the chalkboard paint so the primer can adhere properly. Pay attention to the edges and any areas with multiple coats of chalkboard paint—the surface there can be higher or rougher than surrounding walls. The goal is not to remove all the paint but to dull the sheen and smooth any raised edges.
3. Use an Oil-Based or High-Adhesion Primer
After sanding and cleaning the dust away, apply an oil-based primer or a high-adhesion bonding primer. These products are formulated to block stains and provide a stable base over challenging surfaces like chalkboard or dry-erase paints. Apply one even coat and allow it to dry according to the manufacturer’s instructions.
Once dry, inspect the primer for any signs of the underlying chalkboard showing through, including ghosted writing or darker patches. If anything is visible, apply a second coat of primer and let it dry fully. A thorough primer layer makes the topcoat easier to apply and more true to the color you choose.
4. Apply Your Finish Paint
When the primer has fully cured and no underlying marks show through, you can paint with your desired finish. Use quality interior latex or enamel paint and apply two thin, even coats rather than one thick coat for the best coverage and a smooth result. Allow each coat to dry completely before applying the next.
This same approach works for covering other specialty coatings such as dry-erase paint: clean, sand, prime, and then topcoat.
5. Final Tips for Best Results
- Always ensure the surface is clean and dry before sanding or priming; moisture or residue undermines adhesion.
- Use painter’s tape and drop cloths to protect surrounding areas when sanding and painting.
- If dealing with a very dark or heavily used chalkboard, plan for an extra primer coat to fully block ghosting.
- Follow all drying times recommended on primer and paint labels for a durable finish.
With proper preparation—cleaning, sanding, and using a strong primer—you can effectively paint over chalkboard paint and achieve a smooth, consistent finish that looks like the chalkboard was never there.
