Characteristics and Values Table
| Characteristics | Values |
|---|---|
| Preparation | Clean the surface with soapy water or a wax and grease remover, then dry thoroughly. Use sandpaper to scuff up the surface, starting with a coarse grit and moving to a finer one. |
| Primer | Use a plastic-specific primer or filler primer for rigid plastic. Apply 2-4 thin, even coats, allowing each coat to dry for 5-15 minutes. |
| Adhesion Promoter | Use an adhesion promoter for thermoplastics and flexible plastic. Shake the can well and apply one light coat. |
| Paint | Choose a colour that matches the original or try something new. Apply 2-3 coats, allowing each coat to dry before applying the next. |
| Clear Coat | Optional but adds shine and protects the paint. Wet sand out any imperfections before applying. |
| Lacquer | Use an auto interior lacquer spray. Allow at least 4 hours to dry before removing tape and reinstalling trim pieces. |
| Maintenance | Clean the dashboard with a rag dampened with warm water and a small amount of dish soap to maintain durability. |

Prepping the surface: Clean and scuff the surface with sandpaper, then use a plastic precleaner or adhesion promoter
To prepare the surface of plastic dash parts for spray painting, it is important to clean and scuff the surface. This process will ensure that the paint adheres properly and help to prevent flaking, chipping, and fading.
Start by dismantling the parts of the dashboard that you want to paint. This will allow you to access the plastic parts and lay them flat for easier cleaning and painting. Use a light washing with soapy water to clean the plastic parts. Avoid using a professional degreaser, alcohol, or plastic renovator products like wax or silicone, as these can leave marks on absorbent plastics. Once the parts are clean, make sure they are completely dry before moving on to the next step.
To scuff the surface, use wet and dry sandpaper to create a rough texture on the plastic. Start with a coarser grit and gradually work your way towards a finer one. This process will help the paint adhere better to the surface. Be sure to sand all the areas that will be painted, including any nooks and crannies. After sanding, use a plastic pre-cleaner or adhesion promoter to further enhance paint adhesion. Adhesion promoters are especially recommended for thermoplastics, as they re-flow the plastic and allow for a stronger chemical bond.
Once the surface is properly cleaned, scuffed, and treated with a plastic pre-cleaner or adhesion promoter, it is important to mask off any areas that you do not want to paint. Use painter's tape and paper to protect surrounding areas, such as the windshield, seats, and steering wheel. Make sure the tape is firmly adhered and has no wrinkles to prevent paint from bleeding underneath.
By following these steps, you will have properly prepared the surface of the plastic dash parts for spray painting, ensuring a smooth and durable finish.

Choosing the right products: Select a primer, colour coat, and lacquer
When it comes to choosing the right products for spray painting plastic dash parts, there are a few key considerations to keep in mind. Firstly, it is important to select a primer that will ensure good adhesion and durability. If you are working with hard parts of the centre console made of raw plastic, a plastic primer is essential to ensure the paint adheres well. For flexible plastic components, an "adhesion-promoting primer" is a better option. You can also use an adhesion promoter, such as SEM's products, to further enhance adhesion. If your plastic dashboard is scratched, a "filler primer" can help to conceal these imperfections.
For the colour coat, you can choose a colour that matches the original or opt for something completely different. It is important to consider the type of plastic you are working with and choose a paint that is compatible. Solvent-based paints in a "matt base" version are easy to apply and can be varnished for a homogeneous and even finish. If you are looking for a specific colour, RAL colour charts can be a helpful resource.
Finally, for the lacquer, it is recommended to use a lacquer spray specifically intended for auto interiors. This will protect the paint and ensure its durability. It is important to allow the lacquer sufficient time to dry, ideally overnight or for a full 24 hours if possible.

Applying the primer: Spray an even coat, ensuring full coverage
Before applying the primer, ensure that the surface is clean and free of dust. Use masking tape to cover the areas that you want to protect from the primer and spray paint. It is important to press the tape down firmly to ensure complete adhesion and clean lines. Cover everything within a minimum of 3 feet (91 cm) of the dashboard that you don't want to paint.
When you are ready to apply the primer, shake the can for at least 1 minute before spraying. Hold the can about 10-12 inches away from the surface and spray in a steady, back-and-forth motion, ensuring that you fully cover the surface. Apply at least 2 coats of primer, but 3-4 coats are ideal. Allow each coat to dry for 5 minutes before applying the next one. If the primer still looks damp or if it's a humid day, give it at least 15 minutes before continuing.
The primer will help to create a uniform surface, hiding strong or bright colors and blocking stains that might bleed through the paint. It will also enhance the paint's ability to stick to the surface and last longer. It is important to choose the right type of primer for your project, such as a filler primer for rigid plastic with scratches or an adhesion-promoting primer for flexible plastic.

Spray painting: Use light coats, ensuring no plastic is visible through the paint
When spray painting plastic dash parts, it is important to ensure that the paint adheres well to the plastic surface. To achieve this, the surface must be prepared properly. Firstly, dismantle the parts of the dashboard that you want to paint and lay the pieces flat. Next, clean the surface with soapy water to remove any contaminants. It is important that the surface is completely dry before painting.
Then, sand the plastic parts with P500 abrasive paper or wet and dry sandpaper to create a rough surface for the paint to adhere to. This will help the paint bond with the plastic and prevent chipping. Once the sanding is complete, clean the plastic part with warm water to remove any dirt or debris left by the sandpaper.
After the surface has been prepared, it is time to start painting. Choose a spray paint that is suitable for use on plastics and apply light coats, holding the can about 6-7 inches away from the surface. Ensure that you use enough coats to cover the surface evenly and that no plastic is visible through the paint. It is recommended to apply at least 2 coats of primer and 3-4 coats of paint, waiting 5-15 minutes between each coat to allow adequate drying time.
Additionally, you can apply a clear lacquer or varnish over the paint to add shine and extra protection. Again, allow each layer to dry before adding another coat. Finally, use a microfibre cloth to polish the surface, removing any loose debris and leaving a smooth finish.

Applying the lacquer: Spray the final coat and allow it to dry for at least four hours
When you are ready to apply the lacquer, ensure you have chosen a lacquer spray that is intended for auto interiors. Before you begin, shake the can for at least one minute. Then, spray the final coat, ensuring that you use light, even coats.
After you have applied the lacquer, you must allow it to dry for at least four hours. If you can, it is better to leave it overnight or for a full 24 hours. This will ensure the best results and durability for your paint job.
Once the lacquer is dry, carefully peel away any painter's tape and remove any plastic sheeting and craft paper. Then, reinstall any trim pieces or panels by popping them back into place.
To maintain the durability of your paint job, clean the dashboard occasionally with a rag dampened with warm water and a small amount of dish soap.
