Painting over blackboard paint is a simple process but requires some special equipment. First, the surface must be cleaned thoroughly and allowed to dry. Next, sand down the entire surface, paying close attention to the edges, as the blackboard paint may sit higher than the rest of the paint. Then, apply an oil-based primer and allow it to dry fully. Before painting, check that none of the blackboard paint or chalk lines are visible. If they are, add another coat of primer. Once the primer is dry, you can begin painting over the blackboard paint with your chosen colour.

What You'll Learn
Clean the surface
To paint over blackboard paint, the surface must first be cleaned and prepared. Here are some detailed steps to clean the blackboard surface:
Start by removing any loose chalk dust and debris from the blackboard using a dry cloth. Make sure to brush off any remaining chalk residue. You can use a regular eraser or a soft, dry cloth to wipe down the entire board. It is important to use long strokes from the top left corner towards the bottom to ensure no residue is left behind.
If your blackboard wall is marred with ink, fingerprints, or crayon stains, you may need to use a mild cleaner. Mix a solution of warm water and a few drops of dish soap, and gently scrub the painted areas using a soft-bristled brush or a soft cloth. Make sure to wring out the cloth before wiping the board so it is not dripping wet. You can also try spraying a dusting product like Endust on the cleaning cloth before wiping the board.
For tougher stains, you can use white vinegar, which is a stronger cleaning agent. Mix half a cup of vinegar with four cups of lukewarm water, and use a cloth soaked in this solution to wipe down the board. Rinse the cloth and give the board a final wipe with water to remove any vinegar residue.
Alternatively, you can use lemon oil, which will not only remove chalk dust but also leave your chalkboard smooth, clean, and shiny. Place two teaspoons of lemon oil on a dry cloth, fold it into a square, and put it into a sealed plastic bag. After letting it sit for a day, remove the cloth and wipe down the board.
Another unusual but effective cleaning solution is cola. Soak a sponge in cola, squeeze out the excess, and start wiping from the top of the board, working your way down. Rinse and recoat the sponge as needed, and then use a damp microfiber towel to remove any cola residue.
Once you have cleaned the surface, make sure to let it air dry completely before you start painting over it.

Sand the surface
To paint over blackboard paint, you must first sand the surface. This is an important step in preparing the surface for a new coat of paint. Here is a step-by-step guide to sanding a blackboard surface:
- Clean the surface: Before sanding, ensure that the blackboard surface is clean and free of any dirt, dust, or chalk residue. Use a damp cloth or rag to wipe down the surface thoroughly.
- Choose the right sandpaper: For sanding a blackboard surface, it is recommended to use fine-grit sandpaper. This type of sandpaper will help create a smooth finish and even out any rough spots or bumps on the surface.
- Lightly sand the surface: Start by lightly sanding the blackboard surface with the fine-grit sandpaper. Use gentle, even strokes and apply light pressure. The goal is to create a smooth surface that is ready for the next step of primer or paint.
- Wipe away dust: After sanding, use a damp cloth or rag to wipe away any dust or debris from the surface. It is important to remove all the sanding dust before proceeding to the next steps.
- Fill cracks and holes: If there are any cracks or small holes in the surface, use a filler such as drywall filler or wood putty to fill them in. Allow the filler to dry completely before proceeding to the next step.
- Sand and wipe again: Once the filler is dry, lightly sand the filled areas to ensure they are level with the rest of the surface. Then, use a clean cloth or rag to wipe away any remaining dust.
- Prime the surface (optional): Depending on the condition of the surface and your desired finish, you may choose to apply a primer before painting. This step is optional but can help with better adhesion and a smoother finish.
- Paint the surface: Once the sanding and preparation steps are complete, you are ready to paint over the blackboard surface. Choose a suitable paint for the surface and follow the manufacturer's instructions for application.
By following these steps and properly sanding the blackboard surface, you will create a smooth and even base for your new paint, ensuring a professional-looking finish.

Apply primer
Painting over blackboard paint is a straightforward process, but it does require some preparation. If you're working with a surface that has previously been painted with blackboard paint, you'll need to start by thoroughly cleaning it. This will ensure that any chalk residue is removed before you begin painting.
If the surface you're working on is vinyl, wood, or metal, it's important to apply a primer before painting over blackboard paint. A primer will help the new paint adhere properly and create a smooth, even finish.
- Prepare the Primer: Start by reading the instructions on the primer can carefully. Different primers may have specific preparation requirements, so it's important to follow the manufacturer's guidelines.
- Surface Preparation: If you're applying primer to bare wood, it's recommended to sand the surface smooth before beginning. This will create a uniform base for the primer to adhere to. Ensure that you wipe the surface clean after sanding to remove any dust or debris.
- Primer Application: Use a dense foam roller or a suitable primer-specific brush to apply the primer. Start by cutting in the edges using a brush, then fill in the main areas with your roller. Work in light, even coats, ensuring you don't over-roll the primer. Try to maintain a wet edge to avoid lap marks.
- Multiple Coats: Depending on the primer and the surface, you may need to apply several coats of primer. Always refer to the manufacturer's instructions for guidance on the number of coats and the recommended drying time between coats. Lightly sand the surface between coats if necessary for a smoother finish.
- Drying Time: Allow the primer to dry completely according to the manufacturer's recommendations. This could range from a few hours to a full day, depending on the product and the environmental conditions. Ensure good ventilation during the drying process to promote proper curing.
- Inspection: Once the primer is dry, inspect the surface for any imperfections, such as brush strokes, roller marks, or uneven textures. Lightly sand any areas that require smoothing, and apply additional coats of primer if necessary. Ensure the final coat of primer is even and free of defects before proceeding to the next step of your project.

Check for visible chalkboard paint
To check for visible chalkboard paint, start by identifying the surface you're working with. Chalkboard paint can be applied to vinyl paint, wood, metal, or directly onto a wall. If the existing surface is vinyl paint, wood, or metal, a primer will need to be applied first. Once you've determined the surface and whether a primer is necessary, you can move on to the next steps.
Examine the surface for any cracks or imperfections. A smooth, even, and clean surface is ideal for chalkboard paint application. Use drywall putty to fill in any cracks, and then allow ample time for the putty to dry. After drying, lightly sand the surface to ensure it is perfectly smooth, clean, and free of dirt or debris.
When preparing a wall for chalkboard paint, consider the texture of the wall. Chalkboard paint works best on an untextured wall. If the wall has a light texture, you may be able to apply several coats of chalkboard paint, but this is not recommended. It's important to follow the instructions on the chalkboard paint label, as some types may have specific requirements or guidelines.
If you're repainting an existing chalkboard surface, assess the condition of the previous paint job. In some cases, you may need to apply a new coat of paint every six months, especially if the chalkboard is heavily used. Additionally, check if the existing paint has become scruffy or difficult to write on. You may need to apply a few coats of chalkboard paint to refresh the surface and ensure it's ready for writing with chalk or liquid chalk pens.
By following these steps, you can effectively check for visible chalkboard paint and prepare the surface for a new coat of paint. Remember to consider the surface type, apply primer if necessary, address any imperfections, and follow the specific instructions provided by the chalkboard paint manufacturer.

Apply paint
Painting over blackboard paint is a simple process, but it does require some preparation. Firstly, ensure the surface is clean and free of any residual chalk. Use a damp cloth to wipe down the area and let it dry. Once dry, use fine sandpaper to sand down the entire surface, paying close attention to the edges of the blackboard paint as it may sit higher than the rest of the paint or wall. This process will create a rough surface, which will help the new paint adhere better.
After sanding, apply a coat of high-quality, oil-based primer to the entire surface. Allow the primer to dry completely. It is important to follow the instructions on the primer and ensure adequate ventilation during this process. Check that none of the blackboard paint or chalk lines are visible through the primer. If necessary, apply a second coat of primer and let it dry.
Now, you are ready to apply the new paint. Choose a paint that is suitable for the surface you are working with, such as vinyl paint, wood, or metal, and follow the instructions on the paint can. It is recommended to apply several thin coats of paint, allowing each coat to dry for the recommended time before applying the next one. This will ensure a more even and durable finish.
Before using the new paint, test it on a small, inconspicuous area to ensure it adheres well and there are no unexpected reactions with the primer or underlying blackboard paint. If the test area looks good and you are satisfied with the colour and finish, proceed to paint the entire surface.
With these steps, you can successfully transform your blackboard wall, door, or surface into a fresh new canvas, hiding any signs of the previous chalkboard paint.
