Plasti Dip is a flexible, durable, and insulating rubber coating that can be applied by dipping, brushing, or spraying. It is commonly used to coat tool handles, metal handrails, and car parts. To enhance the non-slip properties of Plasti Dip, grit can be added between coats. While some sources suggest using a fine grit, others recommend specific grit numbers such as 320, 350, 1000, or even a range from 800 to 1200. The choice of grit depends on the desired texture and finish, as well as the object being coated.

What You'll Learn
Pumice (crystalline silica) grit is best
When using Plasti Dip, a grit additive can be used to enhance the non-slip properties of the product. While different grits can be used, for the best results, pumice (crystalline silica) grit is recommended. Pumice grit is a safe, non-crystalline silica filler made from a naturally pure, micronized pumice that can add functional improvements to paint and industrial coatings. Pumice grit is sourced from the world's purest commercial deposit of white pumice.
Pumice grit can be used in a variety of applications, including as a traction aid for ice and snow, and as a functional filler in paints, coatings, rubber, plastics, and fiberglass compounds. It is important to note that crystalline silica has been identified as a carcinogen, so it is essential to follow safety guidelines when using this type of grit.
When using Plasti Dip, the surface to be coated should be clean, and some sources recommend scuffing or sanding the surface beforehand. The grit can then be added between coats of Plasti Dip to enhance its non-slip properties.
In addition to its functional benefits, pumice grit can also improve the appearance of the final product. When used as a sanding and finishing grit, pumice can create a smooth and intricate finish on wood or metal surfaces. By using long straight strokes that track with the grain of the wood, and maintaining even pressure, the pumice grit can enhance the beauty of the piece.
Overall, pumice (crystalline silica) grit is the best option for use with Plasti Dip due to its superior functional and aesthetic properties, as well as its versatility in a range of applications.

Sanding with 1000 grit is sufficient
Sanding with 1000-grit sandpaper is sufficient for some projects. The grit of sandpaper refers to the size of the abrasive particles on its surface. Finer grits have smaller particles and smoother textures, while coarser grits have larger particles and rougher textures. The grit of sandpaper determines how abrasive it is and what it is used for.
Coarse sandpaper grits, ranging from 40 to 60 grit, are used for heavy sanding and stripping. Medium grits, ranging from 80 to 120 grit, are used for smoothing surfaces and removing small imperfections. Fine grits, ranging from 150 to 220 grit, are used for sanding between paint coats and shaping, levelling, and removing finishes. Ultra-fine grits, ranging from 400 to 1000 grit, are used for the final sanding of wood for a smooth finish.
When using Plasti Dip, a flexible and durable rubber coating, sanding with a fine grit is often sufficient. Plasti Dip can be used for a variety of applications, including coating metal handrails, repairing broken wires, and coating battery cables. It can also be used to improve grip and provide a non-slip surface. While some sources mention using 350-grit or a "pretty fine grit" sandpaper to scuff surfaces before applying Plasti Dip, others claim that there is no need to scuff or sand, as long as the area is clean. One user reported that they achieved good results by sanding with 1000-grit sandpaper before applying Plasti Dip to their front lip.
In general, the grit of sandpaper you choose will depend on the specific project and the type of surface you are working with. It's important to select the right grade for the job, as using sandpaper that is too coarse can leave scratches and damage the surface, while using sandpaper that is too fine may not be effective. For projects that require a smooth finish, such as sanding wood or preparing a surface for painting, a finer grit in the range of 1000 grit may be sufficient.

350 grit sanding sponge for scuffing
When using Plasti Dip, a flexible and durable rubber coating, it is not always necessary to scuff, sand or perform any other extensive prep work. However, if you do wish to scuff before applying Plasti Dip, a 350-grit sanding sponge can be used to scuff the entire housing, including the silver and plastic parts.
A 350-grit sanding sponge is a medium-grit sponge that can be used to scuff or lightly scratch surfaces before painting. Sanding sponges are designed to provide a better surface finish, especially for curved and contoured areas. They are highly flexible and can reach tight, hard-to-reach spots, making them ideal for automotive body repairs and touch-ups.
When using a 350-grit sanding sponge for scuffing, it is important to sand with the grain of the surface and work through a sequence of grits, from coarse to very fine. This means starting with a coarse grit and gradually moving to a finer grit, without skipping more than one grit between each sanding step. For example, you could start with a 220-grit sanding sponge and work your way up to a 350-grit or finer sponge.
Additionally, when using Plasti Dip, it is recommended to add grit between coats to enhance the non-slip properties of the coating. While a specific grit size is not mentioned, it is suggested to use pumice (crystalline silica) grit for the best results.

Coarse grit sandpaper to remove old coats
When using Plasti Dip, it is not always necessary to scuff or sand the surface before application. However, if you need to remove old Plasti Dip coats, coarse grit sandpaper can be used.
Sandpaper grit measures the coarseness of the paper, with lower grit numbers indicating a coarser texture. Coarse grit sandpaper typically has a grit level ranging from 12 to 220, with most home sanding projects requiring a grit size between 60 and 220.
For removing old Plasti Dip coats, it is recommended to use a moderately coarse grit sandpaper with a grit between 180 and 600. This will help to avoid scratching the surface. It is also important to use specific sandpaper designed for wet sanding plastic, as this technique is less likely to cause scratches.
When wet sanding, start by cleaning the plastic with a solution of detergent and a soft cloth. Then, use lukewarm water and a few drops of dish soap to lubricate the sanding process and prevent the sandpaper from clogging. Clean the sanded plastic with a damp cloth before applying a new coat of Plasti Dip.
It is important to note that the grit size can be adjusted depending on the desired finish. For a smoother finish, a finer grit sandpaper with a higher grit number can be used. Additionally, adding grit between coats of Plasti Dip can enhance its non-slip properties.

Grit additives improve non-slip properties
Plasti Dip is a flexible and durable rubber coating that can be used on a variety of surfaces, including metal, plastic, and wheels. It is often used for DIY projects and car customization, providing an easy way to change the appearance of an object or surface.
When using Plasti Dip, it is important to consider the grit additive to improve the non-slip properties of the coating. Grit additives, such as pumice (crystalline silica) grit, can be added between coats of Plasti Dip to enhance its grip and make it more resistant to slipping. This is especially useful when coating surfaces that require extra traction, such as metal handrails or steps.
The grit size or grit range can vary depending on the desired finish and the surface being coated. For a smooth finish, a finer grit size is recommended, while a coarser grit can be used to remove old coatings or create a textured surface. Sanding with grit sizes ranging from 320 to 1000 has been mentioned by some users, depending on the project requirements and the desired level of smoothness.
It is worth noting that proper surface preparation is essential for optimal results. This includes cleaning the surface, ensuring it is free of dirt and debris, and considering the use of a compatible primer. Additionally, the number of coats of Plasti Dip can be adjusted to achieve the desired thickness and durability.
By choosing the appropriate grit additive and following the recommended application techniques, users can enhance the non-slip properties of Plasti Dip, making it a versatile and effective solution for a wide range of projects.
