Plasti Dip is a flexible, peelable, and durable rubber coating that can be applied to a variety of surfaces, including plastic. It is often used for automotive customization and DIY projects, providing protection against moisture, acids, corrosion, and skidding. Before applying Plasti Dip, it is important to prepare the surface by cleaning and drying it thoroughly. This ensures that the Plasti Dip adheres properly and creates a smooth finish. When applying Plasti Dip, it is recommended to work in a well-ventilated area and use tools such as paint rollers or brushes for even coverage. Multiple coats of Plasti Dip may be applied, allowing adequate drying time between each layer. While Plasti Dip is a popular option for temporary customization and protection, it may not be suitable for achieving a permanent paint job on plastic surfaces.

What You'll Learn
Prepare your workspace and item
To prepare your workspace and item for dip painting plastic, follow these steps:
Firstly, ensure your work area is well-ventilated. Inhaling fumes from primer can be harmful, causing side effects like headaches, dizziness, or nausea. Keep windows open, and use a fan to blow air out of the room. If you're particularly concerned about fumes, wear a safety mask or a specialised gas mask to protect your nose and mouth.
Next, lay down a tarp, plastic sheeting, or newspaper on the floor or a countertop to protect the underlying surface from primer and paint. If you're painting a smaller item, newspaper will suffice; for larger items or surfaces, use a tarp or plastic sheeting.
Now, gather your supplies. You'll need a primer made for plastic, paint designated for use on plastic, and a paint stirrer or roller. If you're using Plasti Dip, you can mix different colours to achieve your desired shade. Add approximately 1/3 of a 1 oz. tube per 14.5 oz. can of Plasti Dip.
Before you begin painting, prepare your item. If the plastic has existing stains, pour rubbing alcohol onto the stain and let it sit for 10-20 minutes before scrubbing it away. Then, wash the item with soapy water and a sponge or clean rag, ensuring it is thoroughly cleaned. Rinse the item and let it dry completely for at least an hour.
Once the item is dry, use fine-grit sandpaper or a sanding block to roughen the surface, especially if it has shiny parts. This will help the paint adhere better. Sand the entire surface with light to medium pressure, using circular motions. If the item has curved surfaces or small crevices, sandpaper may be easier to use than a sanding block. Finally, wash off any dust or sand residue with water and let the item dry again.

Mix and apply Plasti Dip
Plasti Dip is a rubber coating used to colour and protect cars, tools, and other metal items. It is available in a variety of colours and finishes, including Plasti Dip Camo, Plasti Dip Blaze, and Plasti Dip Luxury Metal.
To mix and apply Plasti Dip, follow these steps:
Preparation
Before you begin, ensure your work area is well-ventilated and out of direct sunlight, high humidity, or breezy conditions. Also, make sure the surface you want to apply Plasti Dip to is clean and dry. If the can of Plasti Dip is cold, place it in warm water for 5 minutes before shaking it to ensure a smooth finish.
Mixing
Open the can of Plasti Dip and place a long, thin item like a paint stirrer inside. Stir slowly and gradually in a circular motion to ensure the substance is smooth and consistent. Avoid stirring too quickly to prevent spills. If you want to create a custom colour, you can mix different colours of Plasti Dip or add tinting colours purchased from a hardware or paint store.
Application
There are several ways to apply Plasti Dip, including dipping, brushing, and spraying.
- Dipping: Attach a wire or string to the item you want to coat, allowing you to submerge and lift the item easily. Slowly lower the item into the Plasti Dip, counting to 5 as you lower it by 1 inch (2.5 cm) intervals. Once the desired amount is coated, gradually remove the item at the same rate.
- Brushing: Pour a small amount of Plasti Dip into a plastic container and dip a short-haired roller into it. Roll the roller back and forth until it is completely covered in Plasti Dip. This method is best for smaller objects.
- Spraying: Hold the spray can 12-16 inches away from the object and sweep it horizontally as you spray, releasing the nozzle when you pass the edge of the item. Apply at least 4 coats, with the first coat being very light, to ensure a smooth finish.
Drying
After applying Plasti Dip, allow it to dry completely. For best results, wait at least 30 minutes between coats, and 4 hours for the final coat to fully cure before touching or using the item.

Use a roller or brush
Painting plastic can be done using a roller or brush, and the process is quite straightforward. Here is a step-by-step guide to help you get started:
Prepare your workspace:
It is important to work in a well-ventilated area when painting. Set up your workspace by laying down plastic sheeting on a flat surface, such as a table, to protect it from paint drips. Gather your supplies, including the paint, roller or brush, a paint tray, and the plastic item you wish to paint.
Clean the plastic surface:
Before painting, ensure the plastic surface is clean, dry, and free of dust. You can use a suitable detergent or sugar soap to remove any dirt, moss, or algae. For heavily soiled items, use a sponge or scrub brush with warm water and dish soap, then rinse thoroughly. If you are working with plastic that has been previously painted, you may need to use a scraper or stiff-bristle brush to remove loose materials.
Sand the plastic:
Since paint adheres better to rough surfaces, sanding is essential to creating a good base for the paint to stick to. Use sandpaper to scuff up the surface, especially if the plastic has a glossy finish. This will help the paint adhere better and create a more durable finish.
Prime the plastic (optional):
Priming is not always necessary, but it can improve adhesion and create an even finish. Choose a low-odor, all-purpose exterior primer suitable for plastic surfaces. Apply the primer according to the manufacturer's instructions and allow it to dry completely before painting.
Choose the right paint:
Select a paint that is specifically formulated for plastic surfaces. Manufacturers like Rust-Oleum offer paints specifically formulated for plastic, such as spray or brush-on options. You can also use multi-surface paints, which are self-priming and can be applied by brush, roller, or spray.
Start painting:
If using a roller, pour a small amount of paint into a tray and dip the roller into it, rolling it back and forth until it is completely covered. If using a brush, dip the brush into the paint and ensure it is evenly coated. Apply the paint to the plastic surface using long, even strokes. Work in smooth, fluid directions to avoid obvious roller or brush marks.
Allow the paint to dry:
Once you have finished painting, step away and allow the first coat to dry. This usually takes about 30 minutes, but it may vary depending on the paint you are using. If coating both sides of the item, you may need to let one side dry completely before flipping and painting the other side.
Remember to always work in a well-ventilated area and follow the safety instructions on the paint and primer labels. With these steps, you can successfully paint plastic using a roller or brush, creating a durable and even finish.

Paint in long, even strokes
Painting in long, even strokes is a crucial step in achieving a smooth and consistent finish when dip-painting plastic. Here are some detailed instructions to help you master this technique:
Start by preparing your workspace. Cover your work area with plastic sheeting or old newspapers to protect it from paint drips and spills. Gather all the necessary supplies, including your chosen paint, a paint roller or brush, and the plastic item you wish to paint. Ensure the plastic surface is clean and dry before you begin painting.
When you're ready to start painting, dip your roller or brush into the paint. If using a roller, push it forward and roll it back and forth in the paint tray until it's completely covered. If using a brush, simply dip the bristles into the paint and ensure they're evenly coated.
Now, it's time to apply the paint to the plastic surface. Begin by positioning the roller or brush at the top of the item and gently applying pressure as you move downward in a slow, steady stroke. Aim for a smooth and fluid motion, ensuring the paint is applied evenly across the surface. Release the pressure at the end of the stroke, lifting the roller or brush slightly to create a consistent finish.
Repeat this process, working your way across the plastic surface with long, even strokes. Ensure each stroke overlaps slightly with the previous one to avoid leaving any unpainted areas or noticeable marks. If using a brush, try to paint in a single direction to prevent obvious brush marks.
Take your time and maintain a steady hand throughout the process. Remember, the key to achieving a high-quality finish is consistency and evenness in your brushwork. By using long, even strokes, you'll be able to create a smooth and professional-looking result.

Allow time to dry and cure
Allowing your paint job to dry and cure is an important step in the process of dip-painting plastic. The drying and curing process will ensure that your paint job lasts longer and that the paint does not peel off prematurely. Here are some key points to consider:
Drying Time:
- The drying time for dip-painted plastic items can vary depending on the product and climate conditions. In general, it is recommended to allow at least 30 minutes for the first coat to dry before applying subsequent coats.
- For Plasti Dip, the manufacturer recommends a minimum of 30 minutes of drying time between coats and a minimum of four hours of dry time before using the item.
- When applying multiple coats, it is important to allow each coat to dry completely before applying the next one. This will ensure that the paint layers adhere properly.
- If you are painting in a cold climate, you may need to allow for additional drying time. Warming the cans in warm water prior to application can help achieve a smoother finish and reduce the need for extra dry time.
- High humidity, high temperatures, windy conditions, and direct sunlight can negatively impact the drying process and should be avoided. Ideal conditions for drying are low humidity, a temperature of around 70 degrees Fahrenheit, and minimal air movement in a well-ventilated area.
Curing Time:
- Curing refers to the process of the paint reaching its full hardness and durability. The curing time for Plasti Dip is approximately six hours, although this may vary depending on ambient conditions such as temperature and humidity.
- It is important to allow the paint to fully cure before using the item or exposing it to harsh conditions. This will ensure that the paint is durable and can withstand normal use.
- If you are painting a car or other vehicle, it is recommended to wait at least 48 hours before washing the vehicle. Hand washing is always recommended over automatic car washes, as they may use methods that are not dip-safe.
- To protect your paint job and ensure it stays in the best condition, you can use a dip coat protective spray. This will help resist marring, scratches, and staining, making it easier to clean and maintain.
