Plasti-Dip is a versatile product that can be used for a variety of DIY projects, from customising cars to repairing plastic items. Before applying Plasti-Dip to plastic surfaces, it is important to ensure that the surface is clean and dry. Any dirt, grease or residue can cause issues with the final finish, including texture problems and small bubbles. Using a cleaner that does not leave a residue is recommended, and it is also important to ensure that the surface is completely dry before proceeding. Some sources suggest using a primer to improve adhesion, especially on smooth, shiny surfaces. However, this is not always necessary as Plasti-Dip will shrink around the item as it dries.

What You'll Learn

Clean the surface with soap and water
When prepping plastic for Plasti Dip, cleaning the surface with soap and water is a crucial step. This process ensures that the Plasti Dip adheres properly and creates a smooth and durable finish. Here's a detailed guide on how to effectively clean the surface with soap and water:
Firstly, gather your cleaning supplies. You'll need a mild soap or detergent that doesn't leave a residue. A gentle dish soap, such as Dawn, is often recommended for this purpose. Ensure you have a clean cloth or towel specifically for drying the surface afterward. Avoid using shirts with designs or logos, and stay away from paper towels, as these can create scratches on the plastic surface. A recommended option is a Meguiar's Water Magnet Drying Towel or any terry cloth towel.
Next, mix a small amount of soap with warm water. You want to create a mild soapy solution. Dip a clean cloth or sponge into the soapy water and wring it out to remove excess liquid. You want the cloth to be damp, not dripping wet. Gently wipe down the plastic surface with the damp cloth, ensuring you cover every inch of the area you plan to Plasti Dip. Pay extra attention to areas that may have built-up dirt, grease, or grime. You can also use this soapy solution to clean the wheels if you plan to dip them as well.
After you've thoroughly cleaned the surface, it's important to rinse the soap off. Use a separate clean cloth or sponge, and dampen it with plain warm water. Go over the entire surface again, rinsing away any remaining soap residue. Ensure that you don't leave any soapy residue behind, as this could interfere with the adhesion of the Plasti Dip.
Once the surface is rinsed, it's time to dry it thoroughly. Use the cloth or towel you prepared earlier to carefully dry the plastic surface. Make sure to absorb any remaining moisture to prevent water spots or streaks. It's crucial that the surface is completely dry before you proceed with the Plasti Dip application. You can also let the surface air dry for a while before using the towel to ensure no moisture is left behind.
Finally, inspect the surface to ensure it is spotlessly clean and dry. Check for any remaining dirt, dust, or grease that might have been missed during the cleaning process. If you notice any contaminants, repeat the cleaning process on those specific areas. Remember, a clean surface is essential for achieving the best results with Plasti Dip.
By following these steps, you'll effectively clean and prepare the plastic surface with soap and water, ensuring a successful Plasti Dip application.

Use a drying towel to remove moisture
When prepping plastic for Plasti Dip, it is critical to ensure that the surface is thoroughly dry. Water or any other form of moisture can cause the Plasti Dip to not adhere properly, resulting in lifted areas that will continue to grow until the panel needs to be peeled. Therefore, using a drying towel to remove moisture is an essential step in the process.
To effectively use a drying towel for this purpose, it is recommended to use a specialised drying towel like the Meguiar's Water Magnet Drying Towel. This type of towel is designed to absorb moisture and minimise the risk of scratches. However, if you do not have access to a specialised drying towel, a regular terry towel can also be used. It is important to avoid using shirts with designs or logos, as well as paper towels, as these can create scratches on the surface.
When using the drying towel, make sure to wipe down the surface gently but thoroughly. Ensure that all areas are completely dry, paying extra attention to corners, crevices, or intricate details on the plastic surface. It is crucial to remove all traces of moisture to ensure the best adhesion of the Plasti Dip.
Additionally, it is important to note that this step should be performed after cleaning the plastic surface. The cleaning process can involve using soap and water, specialised cleaners like the pre-dip cleaner from DipYourCar, or a combination of water and dish soap (Dawn is a popular choice). Ensure that any cleaning agents are thoroughly rinsed off before proceeding to the drying step.
By following these guidelines and using a drying towel to remove moisture, you can ensure that your plastic surface is properly prepared for Plasti Dip application, reducing the chances of adhesion issues and ensuring a smooth and successful outcome.

Sand the plastic
Sanding the plastic is an important step in preparing plastic for Plasti Dip. It is crucial to use the right type of sandpaper and apply the correct amount of pressure to achieve the desired results. Here is a step-by-step guide:
- Choose the right grit sandpaper: Select a fine-grit sandpaper, such as 800 or 1000-grit sandpaper. Finer grit sandpaper will help create a smoother finish and is especially important when working with plastic, as it can be more delicate than other materials.
- Lightly sand the plastic: Gently sand all the plastic surfaces you plan to treat with Plasti Dip. Avoid applying too much pressure, as you only need to create a slightly rough surface for the Plasti Dip to adhere to. Use smooth, even strokes and ensure you cover all areas.
- Wipe down the surface: Once you have finished sanding, use a clean, dry cloth to wipe away any dust or debris created during the sanding process. You can also use rubbing alcohol or a pre-dip cleaner to ensure the surface is completely free of any residue.
- Allow the surface to dry: After wiping down the sanded plastic, let it air dry completely. This step is crucial, as any remaining moisture can affect the adhesion of the Plasti Dip.
- Mask off surrounding areas: If you are working on a specific area of plastic, use masking tape or cardboard to cover any surrounding areas that you do not want to be coated with Plasti Dip. This will help create clean, precise edges and prevent overspray.
- Test on an inconspicuous area: Before proceeding, it is always a good idea to test the Plasti Dip on a small, inconspicuous area of the plastic. This will allow you to ensure that the sanding process has been effective and that the Plasti Dip adheres correctly.
- Apply Plasti Dip: Once you have completed the above steps and are satisfied with the test area, proceed to apply the Plasti Dip following the manufacturer's instructions. Remember to work in a well-ventilated area and follow all safety precautions.
Remember that Plasti Dip is a versatile product that can be applied to a variety of surfaces, including plastic. While sanding is an important step, always refer to the specific instructions provided with your chosen Plasti Dip product, as different applications may have varied requirements.

Use a pre-dip spray
When preparing plastic for Plasti Dip, using a pre-dip spray is a crucial step. A pre-dip spray helps to ensure that the surface is completely free of any contaminants, which is essential for the Plasti Dip to adhere properly.
The first step is to clean the plastic surface thoroughly. This can be done with soap and water, or a pre-dip cleaner like DipYourCar, ensuring that any wax, grease, or dirt is removed. It is important to note that any residue left on the surface can prevent the Plasti Dip from adhering properly, so a thorough cleaning is necessary.
Once the surface is clean, the next step is to apply the pre-dip spray. It is recommended to use a wax cleaner like DipYourCar PreDip spray, which can be sprayed onto a towel and then used to wipe down the surface. This will help to remove any remaining oil or grease residue and ensure that the surface is completely clean.
It is important to avoid spraying the pre-dip spray directly onto the plastic surface, as this can lead to overspray. Instead, spraying it onto a towel or cloth first ensures a more controlled application and helps to avoid any potential damage to the plastic.
Additionally, it is crucial to work in a well-ventilated area when using the pre-dip spray, as some of these products may contain chemicals that can be harmful if inhaled. It is always important to follow the instructions and safety precautions provided by the manufacturer of the specific pre-dip spray being used.
By following these steps and using a pre-dip spray, you can effectively prepare a plastic surface for Plasti Dip, ensuring a strong adhesion and a high-quality finish.

Tape off the area
Taping off the area is an important step in the plasti-dip process. It ensures that the surrounding areas are protected from any overspray or accidental application of the plasti-dip. Here are some detailed instructions on how to tape off the area before applying plasti-dip:
- Clean the surface: Before taping off the area, make sure the surface is thoroughly cleaned and dried. Use a suitable cleaner that does not leave any residue. For example, you can use water and dish soap, such as Dawn, as recommended by some users. A Meguiar's Water Magnet Drying Towel or any terry cloth towel can be used to dry the surface, avoiding paper towels or shirts with designs, which can cause scratches.
- Mask off the area: Use painter's tape or masking tape to mask off the areas surrounding the surface you want to plasti-dip. This will create a barrier that protects those areas from any accidental overspray. Make sure to press the tape firmly against the edges of the target area to ensure a sharp and clean line.
- Protect surrounding areas: If there are any sensitive or easily damaged areas near the target surface, consider covering them with plastic sheets or drop cloths for added protection. This will catch any potential overspray and make cleanup easier.
- Plan your application technique: Depending on the size and shape of the surface, plan your approach for applying the plasti-dip. For example, if you are plasti-dipping a car, consider removing the wheels for easier access and a cleaner application. Decide whether you will use aerosol cans or a sprayer for the best coverage.
- Prepare for multiple coats: Plasti-dip often requires multiple light coats for the best results. Plan for the number of coats you want to apply, as this will impact the amount of plasti-dip and time required. Allow for the necessary drying time between coats, usually about four hours for curing.
- Practice tape removal: It is essential to learn how to remove the tape properly. The best time to remove the tape is when the last coat is still wet. If it dries completely, use a scraper or putty knife to score the plasti-dip around the taped-off area gently. Practising this technique will ensure that you can remove the tape smoothly without damaging the underlying surface or the plasti-dip itself.
Remember that taping off the area is a crucial step to achieving a clean and precise application of plasti-dip. Taking the time to prepare the surface and its surroundings will result in a more professional-looking finish.
