Transforming Mirrors With Chalkboard Paint: A Creative Diy Project

can i paint over a mirror with chalkboard paint

Painting over a mirror with chalkboard paint is a simple DIY project that can be used in any part of your home with any mirror, new or old. It can be done using brush-on chalkboard paint or chalkboard spray paint. Before painting, the mirror should be cleaned and dried, and the frame should be taped off to prevent overspray. The first step is to lightly sand the mirror with an abrasive pad or medium-grit sandpaper. Then, a primer should be applied and allowed to dry. After the primer dries, you can apply the chalkboard paint. It is recommended to apply two to four coats of paint, allowing sufficient drying time between coats. Once the final coat is dry, the painter's tape can be removed. To finish, the chalkboard should be seasoned by shading the entire surface with chalk and then wiping it clean.

Painting the back of the mirror

Painting the back of a mirror is a great way to repurpose it as a chalkboard while keeping the option to turn it back into a mirror in the future. Here is a step-by-step guide to achieving this:

Step 1: Clean the Surface

Use a microfiber cloth to clean the back of the mirror. Ensure that you dry the surface completely. It is recommended to avoid paper towels as they can leave lint on the glass, which can get stuck in the paint.

Step 2: Prepare the Area

Use painter's tape to cover the edges of the mirror, where the frame meets the glass. Take the mirror outside and lay it down on a flat surface covered with newspaper or any protective material. This will prevent paint from getting on unwanted surfaces.

Step 3: Sand the Surface (Optional)

Lightly sand the back of the mirror with an abrasive pad or medium-grit sandpaper. This step will help the paint adhere better to the surface.

Step 4: Prime the Surface (Optional)

Apply a primer to the back of the mirror and let it dry completely. A primer will improve the adhesion of the chalkboard paint. However, if you are using chalkboard spray paint, you can skip this step as the spray paint usually has good adhesion even without a primer.

Step 5: Paint the Surface

Apply the chalkboard paint to the back of the mirror. You can use a brush or a foam roller for this step. If using a brush, cut in the edges first and then use the roller for the large part of the mirror to eliminate brush marks. Allow the paint to dry completely between coats. Apply at least two coats of paint for better durability.

Step 6: Reassemble and Cure

After the final coat of paint has dried, reassemble the mirror by screwing the backing back onto the frame. Allow the chalkboard paint to cure for at least three days.

Step 7: Season the Chalkboard

Once the paint has cured, season the chalkboard by shading the entire surface with chalk and then wiping it clean. This step is crucial as it fills the pores of the chalkboard paint, ensuring that you can easily erase what you write on the board.

Step 8: Write and Draw

Finally, your chalkboard mirror is ready to use! Hang it in your desired location and start writing or drawing with chalk. Enjoy your new decorative and functional piece!

Using a primer

Painting over a mirror with chalkboard paint is a simple DIY project that can be used in any part of your home with any mirror, new or old. It can be used in a kitchen to write out meals or groceries, in an office to brainstorm ideas, or in a playroom.

Before applying chalkboard paint, it is important to use a primer. Priming is necessary to avoid issues such as bleed through, where stains or paint from the previous surface seep through the new layer of paint. To avoid this, use a bonding primer, such as Valspar Bonding Primer, which can be found at Lowe's Home Improvement stores. If you are priming over a clear coat, you can use a bonding primer or sand down the surface and start again. If you are priming stained furniture, it is recommended to sand the surface before applying the primer.

After applying the primer, let it dry completely. The drying time will depend on the temperature and humidity, so if it is cold or humid, bring the mirror inside to dry. Once the primer is dry, you can apply the chalkboard paint.

For the best results, it is recommended to apply two coats of chalkboard paint, allowing a couple of hours of drying time between coats. To eliminate brush marks, cut in the edges with a brush and use a small foam roller for the large part of the mirror. After the final coat, wait at least 24 hours before using the chalkboard. To prepare the chalkboard for use, run a piece of chalk over the entire surface and then wipe it clean.

Painting the mirror frame

Painting a mirror frame is a simple DIY project that can transform your space. If you're looking to give your mirror frame a makeover, here's a step-by-step guide to help you achieve a professional-looking finish:

Prepare the Workspace and Materials:

Start by laying down newspaper or a drop cloth to protect your work area from paint drips and spills. Gather your materials, including the paint of your choice, paintbrushes or rollers, sandpaper, painter's tape, and a razor blade or utility knife.

Clean and Sand the Frame:

Remove the mirror from the frame if possible. Clean the frame with a microfiber cloth and water to ensure the surface is free of dust, grease, or other debris. Allow it to dry completely. Lightly sand the frame with sandpaper to create a slightly rough surface, which will help the paint adhere better.

Tape Off the Mirror:

Use painter's tape to carefully cover the edges of the mirror, where the frame meets the glass. This will protect the mirror surface from accidental paint splatters or drips.

Prime the Frame:

Apply a coat of primer to the frame, following the manufacturer's instructions for drying time. Priming will help the paint adhere better and create a smoother finish. If you're using spray paint, you can skip this step, as spray paint typically has good adhesion.

Paint the Frame:

Choose your desired paint colour and apply the paint to the frame using a paintbrush or a small foam roller. Be sure to paint in the same direction as the wood grain if you're painting a wooden frame. Allow the first coat to dry completely before deciding if a second coat is needed. For a durable finish, two coats of paint are recommended, applied a few hours apart.

Reassemble and Decorate:

Once the paint is dry, reassemble the mirror by placing the mirror back into the frame. You can decorate the back of the framed mirror with patterned paper or fabric, using Mod Podge as an adhesive. Cut the excess paper or fabric with a utility knife or razor blade.

Finishing Touches:

Flip over your newly painted mirror and enjoy your handiwork! If desired, you can add further embellishments, such as transfers or other decorative elements, to the frame to give it a unique touch.

Remember to work in a well-ventilated area when painting and always follow the safety instructions on your paint and primer products.

Spray painting

Firstly, carefully remove the mirror from its frame. If you wish to spray paint the frame, now is the time to do so. Take the frame outside and lay it on some newspaper. You can then give it a couple of quick coats of spray paint in your chosen colour.

Next, clean the back of the mirror with a microfiber cloth and water to ensure the paint will stick. Allow the surface to dry completely.

Now, it's time to spray paint the mirror itself. Using chalkboard spray paint, cover the glass surface completely. Apply two coats of paint for added durability, allowing each coat to dry completely before applying the next.

Once the paint is dry, remove the painter's tape and let the mirror sit for at least 24 hours before using the chalkboard. To ensure that what you write on the board can be erased, run a piece of chalk over the entire surface before use.

After this, your chalkboard mirror is ready to be reassembled and hung up.

Sanding the mirror

  • Choose the Right Sandpaper Grit: Select a medium grit sandpaper for sanding the mirror. The grit size refers to the abrasive particles on the sandpaper, and a medium grit falls between the fine and coarse varieties. This grit size will provide a balance between effectively smoothing the surface without causing excessive scratching.
  • Prepare the Work Area: Sanding can create dust and debris, so it's important to work in a well-ventilated area. Consider working outdoors or in a spacious, open space. Wear protective gear, including a respirator or mask to avoid inhaling the dust and safety goggles to shield your eyes from any flying particles.
  • Lightly Sand the Mirror: Using the medium grit sandpaper, gently and evenly sand the surface of the mirror. Apply light pressure and work in smooth, consistent strokes. Cover the entire surface, ensuring that you don't apply too much pressure or linger in one spot for too long to avoid creating deep scratches.
  • Focus on the Edges: If you intend to distress the mirror or create a specific effect on the edges, you can concentrate on those areas after sanding the main surface. Use the same light, consistent strokes, and be cautious not to over-sand, as it is more challenging to reverse this process.
  • Remove Dust: Once you've finished sanding, use a soft, slightly damp cloth to wipe away any dust or debris from the mirror's surface. Ensure no residual dust remains, as it can interfere with the paint adhesion and create an uneven finish.

By following these steps, you will effectively prepare the mirror surface through sanding, ensuring it is ready for the subsequent steps of priming and painting with chalkboard paint. Remember always to work carefully and wear the appropriate protective gear to safeguard your health and safety during the sanding process.
