Painting over mother-of-pearl furniture or surfaces can be a daunting task, especially if the surface is old and has scratches, chips, or fading. To repaint lacquer over mother-of-pearl, it is essential to prepare the surface properly to ensure the new paint adheres well and does not chip off. This may involve light sanding, using a primer, or even applying a wood refinisher for an even base. In some cases, removing the existing lacquer or paint may be necessary, which can be done with acetone or other strippers, but it requires caution to avoid damaging the mother-of-pearl surface. Once the surface is adequately prepared, a new lacquer finish can be applied, preferably using a spray for a smoother result.

What You'll Learn
Sand the surface
Sanding is an important step in preparing a surface for repainting. When it comes to sanding the mother of pearl surface, there are a few key considerations and techniques to keep in mind.
First, it is essential to understand that mother of pearl is a delicate material, and aggressive sanding can easily damage it. Therefore, it is crucial to use fine-grit sandpaper and apply gentle pressure during the sanding process. Aim for sandpaper with a grit of 220 or finer, as this will help ensure you do not remove too much material.
The type of sanding tool you use is also important. For small areas or detailed work, a small file or a radius block with sandpaper attached can be effective. This allows you to focus the sanding on the specific area without affecting the surrounding surfaces. If you are working on a larger surface or want to blend the mother of pearl with the surrounding material, a radius block with fine sandpaper wrapped around it can be used to gently sand the entire area.
It is generally recommended to sand in the direction of the grain, if there is one present, to avoid creating visible scratches on the surface. Take your time and work in gentle, smooth motions rather than applying heavy pressure or rushing the process.
Remember that sanding creates dust and debris, so it is important to work in a well-ventilated area and consider using a dust mask to protect your respiratory health. Additionally, always ensure the surface is clean and free of any oils or contaminants before beginning the sanding process.
Once you have finished sanding, it is crucial to remove any remaining dust or debris from the surface before proceeding with the next steps of your project, such as priming and repainting. You can use a tack cloth or a soft, slightly damp cloth to wipe down the surface gently.

Use a shellac-based primer
When repainting lacquer paint over mother-of-pearl, using a shellac-based primer can be an effective solution. Shellac-based primers, such as BIN or Zinsser's B-I-N primer, are known to work well under latex paint and can help ensure a smooth and durable finish.
It is important to note that shellac alone may not be sufficient as a primer for latex paint, and it is recommended to use a primer intended for latex. However, using a shellac-based primer can provide additional benefits, such as blocking bleed-through and tannin bleed. Before applying the shellac-based primer, it is advisable to lightly sand the surface to create a rough texture for the primer to adhere to. This process is known as "scuff sanding" and provides extra assurance that the primer will stick to the surface.
After scuff sanding, you can apply the shellac-based primer. It is important to ensure even coverage during application, as thin spots may result in unevenness or the primer peeling off. Once the primer is dry, you can proceed with painting. It is recommended to use a lacquer-based paint to avoid potential chemical reactions with the primer.
While shellac-based primers can be effective, they have some drawbacks. They are not known for their durability and may not hold up well against stains, scuffing, or moisture. Additionally, shellac has a strong odor that may linger for a while if not covered with a topcoat. As such, it is essential to consider the specific requirements of your project before deciding to use a shellac-based primer.
Overall, using a shellac-based primer can be a helpful step when repainting lacquer paint over mother-of-pearl. It provides a smooth base, prevents bleed-through, and ensures better adhesion of the paint. However, it is important to consider the limitations of shellac-based primers and take the necessary steps, such as scuff sanding and using lacquer-based paint, to achieve the desired results.

Ensure paint is lacquer-based
When repainting lacquer over mother of pearl, it is important to ensure that the paint you are using is lacquer-based. This is because the chemical composition of the paint will determine its compatibility with the surface you are painting on. Using a non-lacquer-based paint on top of a lacquer finish can cause a chemical reaction between the two, resulting in bubbling, peeling, or other undesirable outcomes.
To ensure that your paint is lacquer-based, check the product's specifications or consult with the manufacturer. If you are using a custom colour, you can request a colour-matched lacquer from several companies by providing them with the paint brand and colour you desire. This will ensure that your paint is compatible with the lacquer finish and help you achieve the desired results.
Additionally, proper surface preparation is crucial. Before applying paint to a lacquered surface, it is recommended to scuff sand the surface lightly and use a suitable primer, such as a shellac-based primer. This will create a better adhesion for the new paint and help prevent any issues.
It is worth noting that if you are working with mother-of-pearl jewellery, the process may differ. In such cases, it is advisable to consult a specialist or seek advice from jewellery-making communities to ensure that your chosen paint is suitable for the specific material and application.
By following these guidelines and ensuring that your paint is lacquer-based, you can help ensure a successful and aesthetically pleasing outcome when repainting lacquer over mother of pearl.

Use a wood refinisher
If you are looking to repaint lacquered surfaces, it is important to prepare the surface well to ensure the new paint adheres properly. One way to do this is by using a wood refinisher. This product can be used to even out the existing lacquer and then put a clear finish over it.
Firstly, it is recommended to use a deglosser to dull the existing finish. You can use a product like Zinsser to do this. This step should be followed by lightly sanding the surface with a 150-grit sanding sponge. It is important not to skip this step as it helps create a surface that the new paint can properly bond to.
After sanding, the next step is to prime the surface. It is recommended to use an oil-based primer such as Benjamin Moore Fresh Start Alkyd. It is important to note that a latex primer should not be used for this step. Allow the primer to dry for a day or two before proceeding to the next step.
Once the primer is dry, you can apply the first coat of your chosen lacquer-based paint. Make sure that the paint you use is lacquer-based to avoid any chemical reactions with the previous finish. After the first coat has dried, apply a second coat of paint for a smooth and even finish.
Using a wood refinisher is a great way to refresh the look of your lacquered surfaces while also preserving the beauty of the wood grain. This method may require more steps and time, but it ensures a durable and long-lasting finish.

Apply two coats of finish paint
When applying two coats of finish paint, there are several factors to consider, including the condition of the surface, paint type, quality, and desired longevity. Here is a step-by-step guide to achieving a professional finish:
Prepare the Surface:
Clear the area, lay down drop cloths, and tape off any trim and windows. Proper preparation prevents paint mishaps and keeps your workspace neat. Ensure the surface is clean and free of dust, grease, or any debris. If there are any stains, use a stain-blocking primer.
First Coat:
Start by applying a smooth, even layer of paint. Use a roller with up-and-down or W-shaped strokes to achieve good coverage. Be patient and let this first coat dry completely.
Inspect and Sand:
Once the first coat is dry, inspect the surface for any drips or rough patches. Use fine-grit sandpaper to smooth out any imperfections. Sanding between coats ensures a flawless finish and helps the second coat adhere better.
Second Coat:
Apply the second coat of finish paint, following the same technique as the first coat. Ensure the paint is applied evenly and smoothly. Allow this coat to dry completely.
Assess the Finish:
Once the second coat is dry, evaluate if the desired coverage has been achieved. In some cases, a third coat may be necessary, especially when using deeper or vibrant colours, or when painting over a darker shade with a lighter one.
Remember, each layer of paint adds depth and evenness to your finish. By taking your time and following these steps, you will achieve a rich, uniform appearance that showcases the true colour and enhances the durability of your project.
