Painting plastic eyeglass frames can be a fun and creative way to give your glasses a fresh, personalised look. It is inherently risky as there is a chance of permanent damage or dissatisfaction with the result. It is best to attempt this on an old backup pair or a cheap pair of glasses. Before painting, it is important to protect the lenses by removing them if possible, or by covering them with painter's tape. The paint options to consider are enamel paint, nail polish, or spray paint. Enamel paint is durable and available in a variety of colours, nail polish is great for custom shades and easy application, and spray paint provides a smooth finish. For plastic frames, water-based or oil-based enamels are most effective.

What You'll Learn
Paint options: enamel paint, nail polish, or spray paint
Painting plastic eyeglass frames can be tricky, as paint does not adhere well to plastic. However, there are a few paint options that you can consider: enamel paint, nail polish, or spray paint. Each option has its own advantages and considerations.
Enamel paint, specifically the type used for auto detailing or pinstriping, can provide a durable finish on plastic eyeglass frames. It is designed to withstand the elements and is less likely to chip or flake off. Before applying enamel paint, it is important to scuff up the frames lightly to help the paint adhere better. You can use steel wool or sandpaper to create a dull, matte surface. It is also crucial to work in a well-ventilated area when using enamel paint.
Nail polish is another option for painting plastic eyeglass frames. While regular nail polish tends to get sticky and takes a long time to cure, UV cure gel nail polish may offer a better alternative. It is important to consider that nail polish might not provide the same durability as other types of paint. Additionally, you would need to be cautious and careful during the application to avoid getting nail polish on the lenses.
Spray paint is often recommended as the best option for painting plastic eyeglass frames. It provides a consistent finish and has a better chance of adhering to the plastic surface. When using spray paint, it is essential to remove the lenses from the frames and work in a well-ventilated area. Lightly scuffing the frames before painting can help improve adhesion. Apply multiple thin coats of spray paint, allowing each coat to dry completely before applying the next. A clear sealant can be applied as the final coat to protect the paint and prevent it from rubbing off.
Each of these paint options has its own set of advantages and considerations. Enamel paint offers durability, nail polish provides a convenient option with UV cure gel varieties, and spray paint gives a consistent finish. It is important to prepare the frames properly, work in a well-ventilated area, and follow the specific instructions for the chosen paint type.

Preparing plastic frames: use fine sandpaper to smooth the surface
Painting plastic eyeglass frames can be tricky, but with the right approach, you can transform their look. Before painting, it's important to prepare the surface properly to ensure the paint adheres well and you achieve a smooth finish.
Start by removing the lenses from the frames if you can do so safely. This will prevent them from getting damaged or painted over. Next, use a fine-grit sandpaper, such as 600-grit or higher, to lightly sand the frames. Sand in circular motions to avoid creating deep scratches on the plastic. The goal is to create a slightly rough texture that will help the paint adhere better. Be careful not to over-sand, as plastic can be challenging to smooth out completely, and you don't want to cut through the plastic.
Once you've finished sanding, wipe away any dust or debris from the frames with a damp cloth. This step is crucial, as any remaining dust can interfere with the paint adhesion. You may also want to clean the frames with warm soapy water and a soft sponge to ensure the surface is free of dirt, grease, or dust, which can also hinder paint adhesion. Allow the frames to dry completely before moving on to the next step.
After sanding and cleaning, you may consider applying a plastic primer designed for use on plastic surfaces. This will further enhance paint adhesion and durability. Choose a plastic-specific primer and apply a thin, even coat to the frames. Allow the primer to dry completely according to the manufacturer's instructions before proceeding to paint your frames.
By following these steps, you'll have properly prepared your plastic eyeglass frames for painting, ensuring a smoother finish and better paint adhesion. Remember to work in a well-ventilated area and take your time between each step for the best results.

Protecting the lenses: remove or cover with painter's tape
Protecting the lenses is crucial when painting eyeglass frames to ensure they remain functional even if you don't like the paint job. The best way to do this is to remove the lenses if you can do so safely. Some frames are easier to remove lenses from than others. If you are unable to remove the lenses, you can cover them with painter's tape.
Painter's tape is useful for covering any areas of the frames you don't want to be painted, such as the logos. You can also use it to create stripes or shapes on the frames before painting them. It is important to note that the paint may not stick well to the tape, so be careful when removing it.
If you choose to remove the lenses, you can take them to a local optical shop to have them reinserted if you have any difficulty putting them back in. This is usually done at no charge.
It is also recommended to use fine sandpaper to roughen the surface of the frames before painting to improve adhesion. This is especially important when using water-based or oil-based enamels.

Painting techniques: apply light coats, avoid brush strokes
Painting plastic eyeglass frames can be a fun way to personalise your glasses and switch up your style. It is important to note that painting your frames comes with the risk of permanent damage or dissatisfaction with the outcome. Therefore, it is recommended to practise on an old or inexpensive pair of glasses.
To achieve a flawless paint job, it is crucial to prepare the frames before painting. Start by removing the lenses if possible, or use painter's tape to cover them. Next, use fine sandpaper to dull the shine of the frames and smooth out the surface for better paint adhesion. If desired, use masking tape to cover any areas or logos you do not want to be painted.
When it comes to painting techniques, the key to avoiding brush strokes is to apply light coats and use the appropriate painting tools. Spray paint is often the easiest method for plastic frames, providing a consistent finish that a paintbrush may not achieve. Place the frames on a flat surface and hold the spray paint can about 6-8 inches away from the surface. Spray lightly with a sweeping motion, always keeping the can in motion and shaking it frequently. Two light coats are usually sufficient, but you can add more if needed. Follow the manufacturer's instructions for recoat timing and drying time.
If using a paintbrush, opt for a small brush with soft bristles to minimise brush strokes. Apply the paint using long, even strokes, and allow each coat to dry completely before applying the next. It is crucial to let the paint dry properly between coats to avoid brush strokes and ensure a smooth finish.

Finishing touches: seal with a coat of clear sealant
Once you are satisfied with the colour of your plastic eyeglass frames, it is important to seal the paint job with a clear sealant. This will ensure that your hard work is protected and will also help keep the paint from rubbing off on your skin.
Before applying the sealant, make sure that the paint is completely dry. The drying time will vary depending on the type of paint you used, so refer to the manufacturer's instructions. It is crucial to let the paint dry properly to achieve a flawless finish. Once the paint is dry, you can proceed with the clear sealant.
For the sealant, you can use a clear spray sealant or a clear coat of nail polish. If using a spray sealant, place your frames on a piece of newspaper and hold the can about 6-8 inches away from the frames. Spray in light, sweeping motions, ensuring that you keep the can moving to avoid applying too much sealant in one area. Allow the sealant to dry completely before touching or handling the frames.
If using nail polish as a sealant, apply a thin coat with the nail polish brush carefully, ensuring you do not get any on the lenses. Allow the nail polish to dry, and then apply a second coat if needed. Again, make sure the sealant is completely dry before handling your frames.
By following these steps and sealing your painted plastic eyeglass frames with a clear sealant, you will protect your new design and ensure its longevity.
