There are several methods to rubberize an existing plastic grip. One way is to use a rubber spray. Another method is to use a rubber coating product such as Plasti Dip or Dip and Grip, which can be brushed or dipped on. To ensure a smooth and durable finish, it is important to follow the instructions on the product, control the humidity, and apply multiple layers. Additionally, for 3D-printed plastic surfaces, acetone can be used to vulcanize ABS, and a heavy texture can be modelled onto the surface.

Using rubber spray
Rubberizing plastic grips can be done using a variety of sprays, including Flex Seal, Plasti Dip, and tool dip. Here is a step-by-step guide on how to use rubber spray to rubberize an existing plastic grip:
Prepare the Surface:
Start by sanding the plastic grip to create a rough texture that will help the rubber spray adhere better. After sanding, wash and thoroughly dry the surface to remove any dust or debris.
Mask Off Surrounding Areas:
Use painter's tape to mask off the areas surrounding the grip that you do not want to get sprayed. This will protect the rest of the object from overspray. You can also use a plastic bag to cover most of the object, which will help save on tape.
Apply the Rubber Spray:
Following the instructions on the rubber spray can, apply the spray to the grip in thin, even coats. Hold the can at the recommended distance and angle, and use a steady back-and-forth motion to ensure an even application. Allow adequate drying time between coats, typically around 30 minutes, and apply at least 3-4 coats for best results.
Remove Tape and Reassemble:
Once you have applied the final coat and allowed it to dry completely (usually around 4 hours), carefully remove the painter's tape. Reassemble any parts that were disassembled during the process, and test out your new rubberized grip!
Tips and Tricks:
- Plasti Dip is available in different colours, so you can choose one that suits your preferences or matches the object. Clear Plasti Dip is also an option if you want to preserve the original colour.
- Be cautious of high humidity when spraying, as it can cause a cloudy or hazy finish on the Plasti Dip.
- The rubber spray may have a strong odour during application, but the scent will dissipate once it is completely dry.
- For added durability, you can apply a clear top coat over the rubberized grip to provide extra protection and ensure the rubber coating lasts longer.
By following these steps and taking note of the tips, you can successfully rubberize an existing plastic grip using rubber spray, creating a comfortable and durable grip for your project.

Laser cutting grip tape
There are various options available for laser-cut grip tape, such as the Lokton™ griptape, which comes in a 40x11-inch sheet with a continuous laser-cut hole pattern for superior footing. The Flexdex® Laser Cut Griptape is another option, which is designed specifically for skateboards and offers a 15-year warranty.
When selecting a laser-cut grip tape, it is important to ensure that it is compatible with the surface you are applying it to. For example, the Jessup ULTRAGRIP™ lasercut Flexdex® diamond design tape is cut specifically for the Flexdex® deck, taking into account the length and hole patterns.
In addition to purchasing pre-cut grip tape, some companies also offer custom laser-cutting services to create grip tape that is tailored to your specific needs and applications. This allows for a more precise fit and can be useful for unique or irregularly shaped items.
By using laser-cut grip tape, you can enhance the grip of plastic surfaces without compromising on thickness or durability. This method provides a simple and effective solution, making it a popular choice for a variety of applications, including skateboards and 3D-printed models.

Silicon over-moulding
If you want to add a rubber grip to an existing plastic handle, silicone over-moulding is a two-step process that can help you achieve that. This process is commonly used to add a grip surface to smooth plastic handles, make integral flexible hinges, and add soft gaskets for waterproofing on plastic housings.
First, a thermoplastic part is injection-moulded and then transferred manually or automatically to a second mould. In the second mould, a liquid silicone rubber (LSR) is injected. This liquid silicone rubber has excellent adhesion to polycarbonate (PC), PBT, Polyamide (PA, Nylon), PET, and PEEK. It is also possible to over-mould silicones with different durometers (hardnesses) onto each other.
Before the injection, the silicone is made from two components that are mixed. Silicone offers high elasticity, resilience, and temperature and chemical resistance. This process can be used to create a toy that can shoot projectiles with an integrated silicone bungee, for example.
If you are looking for a DIY solution, you can try using rubber spray, which can be applied directly to the plastic surface to add grip. Another option is to use a bi-component liquid polyurethane or liquid silicone, which can be moulded or cast around the plastic part. Sugru, a silicone-based product, can also be considered, but its longevity as a grip is questionable without a way of mechanical bonding it to the grip frames.
It is important to note that some products, such as Plasti-dip, may cause the grip to become sticky over time. Additionally, oil-based products, such as lubricants or grease, should be avoided as they can degrade plastics and rubbers over time, even if you think you wiped it all off.

Dip and Grip coating
Dip and Grip is a rubberized plastic coating that can be applied to tool handles, cables, wires, gloves, locks, hardware, and auto parts. The process is simple: just dip the object into the liquid coating and let it dry. The product is available in various colours, including black, red, white, blue, and green.
Dip coating is an innovative process that can significantly enhance various tools and equipment. It improves grip and durability and adds a protective layer. This technique involves immersing an object into a liquid plastic material and then allowing it to cure or solidify. The result is a seamless, protective, and functional coating that can enhance the performance and lifespan of a wide range of tools and equipment.
Dip and Grip is a type of plastic rubber dip, also known as liquid rubber or rubber coating. It is a synthetic compound made from a combination of polymers, elastomers, and plasticizers. When applied, it forms a durable, flexible, and rubber-like coating on various substrates, including metal, plastic, glass, and wood. This coating provides protection against abrasion, moisture, chemicals, and UV radiation. It also insulates against electrical conductivity and prevents corrosion.
Plastic rubber dip is a versatile coating material that offers protection, improved grip, and aesthetic benefits for a wide range of applications. It can be used to coat tools and equipment, providing an enhanced grip and increased comfort during use. The coating is also removable, making it a convenient option for various industrial applications.
Overall, Dip and Grip is a convenient and effective way to add a rubberized coating to existing plastic grips. It improves grip, durability, and protection while providing a range of colour options for customization.
