Clean the surface
To prepare the surface for JB Weld Plastic Bonder, it is important to clean the area of any dirt, grease, oil, paint, rust, or loose debris. Using a detergent or degreaser is recommended for the best results. For example, you can clean the surface with alcohol or something that doesn't leave a residue or melt the plastic.
After cleaning, use a file or coarse sandpaper to roughen the surface, providing an even better repair. This step is especially important when working with plastics, as it helps create a stronger bond. Fine sandpaper can also be used to scuff up the plastic surface and the item being repaired, creating a better adhesion for the glue.
If you are working on a greasy or oily surface, a detergent or degreaser will be necessary to ensure the area is thoroughly cleaned. This step is crucial, as any remaining grease or oil can prevent the JB Weld from properly adhering to the surface.
Additionally, if there is any old paint or rust on the surface, make sure to remove it completely. This can be done by sanding or using a paint stripper, ensuring a smooth and clean surface for the JB Weld to be applied.
By following these steps and thoroughly cleaning and preparing the surface, you will achieve the strongest and most lasting repairs with JB Weld Plastic Bonder.

Prepare the mixture
To prepare the mixture, first clean the surface area of any dirt, grease, oil, paint, or loose debris. It is recommended to use a detergent or degreaser to clean the surface, and then to roughen the surface with a file or coarse sandpaper to provide the best repair.
After cleaning and preparing the surface, you can begin preparing the mixture. Remove the replaceable cap from the syringe and press down on the plunger to dispense the adhesive. Squeeze equal amounts of the two-part adhesive onto a disposable surface to ensure you have a 1:1 mixing ratio. Mix the two parts of the adhesive thoroughly with a stir stick until you have a consistent colour and texture.
It is important to work quickly as the adhesive sets in 15 minutes. You should also mix more than you think you need, as any excess adhesive will be wasted. Once you have a consistent mixture, apply it to the prepared surface with the appropriate tool. Spread the adhesive in an even coat, weld bead, or extruded shape as needed for your repair.
The adhesive will set in 15 minutes and can be sanded after 30 minutes. With a tensile strength of 3770 PSI, the PlasticBonder™ sets to a hard, permanent bond and cures to a black or tan colour depending on the product.

Apply the mixture
When applying the mixture, it is important to work quickly as the adhesive sets in 15 minutes. First, clean the surface area of any dirt, grease, oil, paint, or loose debris. For the best results, use a detergent or degreaser to clean the surface, then roughen the surface with a file or coarse sandpaper. After removing the replaceable cap, press down on the plunger and squeeze equal amounts of each solution onto a disposable surface and mix thoroughly. Apply the mixture with the appropriate tool in an even coat, weld bead, or extruded shape as needed.
For example, if you are repairing a crack, coat both sides of the crack, working on one side at a time with the crack face up to prevent dripping. If you are repairing a hole, you can back up the broken area with a strip of metal or use a staple in the mixture to act as a "rebar" for added strength. You can also cut a strip of plastic and glue it over the crack or hole. If you are repairing a leak, sand the area around the leak and apply the mixture to a small piece of metal or plastic to patch the leak.

Allow it to set
When using JB Weld Plastic Bonder, it is important to allow the adhesive to set properly. This product is a two-part urethane adhesive system with a 1:1 mixing ratio. It is designed to provide strong and lasting repairs on a variety of surfaces, including thermoset, carbon fiber composites, thermoplastics, coated metals, and concrete.
To allow the JB Weld Plastic Bonder to set properly, it is recommended to follow the manufacturer's instructions. According to the manufacturer, the product sets in 15 minutes and can be sanded after 30 minutes. Therefore, it is important to wait at least 15 minutes before handling or moving the bonded items.
During the setting time, it is crucial to ensure that the bonded surfaces remain undisturbed. Any movement or disturbance of the bonded area may affect the strength and integrity of the bond. It is also important to work in a well-ventilated area and avoid contact with the skin and eyes, as the adhesive may produce fumes and can be irritating.
While waiting for the JB Weld Plastic Bonder to set, you can use the time to clean up any tools or surfaces that were used during the application process. It is important to dispose of any unused adhesive properly and according to local regulations. Additionally, make sure to wash your hands thoroughly with soap and water if you come into contact with the adhesive.
Once the JB Weld Plastic Bonder has set, you can proceed with the next steps of your project. Keep in mind that the full curing process may take longer, and it is recommended to allow ample time for the adhesive to cure completely before subjecting the bonded items to any stress or load. The full curing time may vary depending on the temperature, humidity, and the amount of adhesive used.

Sand it down
Sanding plastic is a great way to give the surface more texture and improve its ability to stick to paint. It can also be used to remove paint without harming the plastic underneath. However, plastic is a relatively brittle substance that is easily scratched, so it's important to use the right technique and tools.
When sanding plastic, it's important to keep the sanding paper strokes random and erratic to avoid creating harsh lines or deep scratches. A sanding sponge or foam block can help with this by providing better control and preventing the sandpaper from cutting too deeply into the plastic. It's also important to keep the sandpaper moist to the touch, as dry sandpaper is more likely to scratch the plastic. One way to do this is by using the wet sanding method, where the sandpaper is submerged in water before use. This method is also less likely to cause scratches and is kinder to the sandpaper itself.
If you're sanding plastic in preparation for painting, it's important to start with a clean surface. Use a solution of detergent and water to clean the plastic, and then use moderately coarse sandpaper with a grit between 180 and 600 to start sanding. For a smoother finish, switch to sandpaper with a lower grain size, such as 800–1200 grit. Finally, clean the sanded plastic with a damp cloth and consider polishing it with a clear gloss.
It's important to take safety precautions when sanding plastic to avoid inhaling microplastics. While regular plastic is generally safe to sand, it's still a good idea to wear a mask to avoid breathing in any dust or particles.
