Adding a non-slip texture to plastic can enhance both the visual appeal and functionality of plastic products. Texturing plastics can be challenging, as the process can lead to wear and tear on the mold tooling, and not all plastics respond the same way to texturing processes. The most common way to add texture to plastics is through mold texturing, especially in injection molding processes. This involves using textured molds or inserts that create surface patterns on the plastic as it solidifies, such as grains, stippling, geometric shapes, and more. Post-processing techniques like etching, sanding, bead blasting, coatings, and paint can also be used to add texture to plastic parts.

What You'll Learn
Use self-adhesive non-slip strips
If you want to give a plastic surface a non-slip texture, one easy method is to use self-adhesive non-slip strips. These strips are a quick and simple solution to instantly add traction to any smooth surface. They are particularly useful in wet environments, such as bathrooms, where they can help prevent slips and falls.
You can find these anti-slip strips in various forms, such as rolls, tapes, pads, or stickers, and they usually have a strong adhesive backing that allows for easy application. The strips are often made of vinyl, a durable and versatile material that is resistant to moisture. Vinyl is created by mixing ethylene and chlorine, forming PolyVinyl Chloride (PVC), which can be customised with colours, dyes, and additives to suit different applications.
Before applying the self-adhesive non-slip strips, ensure that the plastic surface is clean and dry. This will help the adhesive stick properly and ensure maximum effectiveness. Once applied, gently press down on the strips to secure them in place.
These strips are versatile and can be cut to size if needed. For example, you can use custom-fit strips to line the bottom of a bathtub or the steps of a staircase. They are also useful for other applications, such as providing traction on slippery floors or even in drawers or cabinets to keep items from sliding around.
Self-adhesive non-slip strips are a convenient and affordable solution for instantly improving safety in your home or workplace. They are easy to install and can be purchased at hardware stores or online.

Sprinkle on a non-skid additive
To give plastic a non-slip texture, one method is to sprinkle on a non-skid additive. This can be done by mixing the additive with a gel coat or paint before application. The non-skid additive provides a durable and textured surface, ensuring that you and your loved ones stay safe by preventing slips and falls.
There are a variety of non-skid additives available on the market, such as Duralux, Griptex, and Aluma Hawk aluminum paint with a non-skid additive. These products are designed to be mixed directly with gel coats or paints, providing an easy and quick application process. The non-skid texture is seamlessly incorporated, resulting in a long-lasting and slip-resistant finish.
When applying the additive, it is recommended to use a flour sifter, powdered sugar shaker, or a punctured container to sprinkle the non-skid additive into the gel coat or paint. By punching holes in the container with a nail or ice pick, you can create a uniform pattern on the surface. This method ensures a consistent and even distribution of the additive, enhancing its effectiveness.
In addition to using non-skid additives, there are alternative methods to create a non-slip texture on plastic. One option is to use non-slip adhesive-backed foam, which can be cut to custom fit the desired area. Another method is to mix clear plastic grit, such as Seal Krete Clear-Grip, into the paint to create a seamless and spotless look while providing traction.
By following these instructions and using the appropriate non-skid additives or alternative methods, you can effectively create a non-slip texture on plastic surfaces, ensuring safety and peace of mind for yourself and others.

Create a basket-weave texture
Creating a basket-weave texture on plastic is an effective way to make it non-slip. Here is a step-by-step guide on how to do this:
Firstly, source plastic bags of all types, colours, and thicknesses. The thicker, more opaque bags will produce a thicker weave, while thin, more transparent bags will result in a thinner weave. Try to get as many colours as possible to create an interesting design.
Next, cut the bags into strips. For most normal-sized bags, you can get three continuous strips about 4 inches wide. First, lay out a plastic bag and fold in the sides. Cut off the very top/handles and the bottom, then open the bag to its full width. Turn the bag so a side seam is facing you, and cut diagonally until you reach 4 inches, then cut in a straight line. Repeat this process for all the bags.
Now, take the strips and double them over, so you have six strands, each with a mate. Secure the looped ends of the strips over something small and sturdy, like a nail, or tape the ends to a table. Divide the strips properly into their pairs and start braiding. Ensure you don't braid too tightly or too loosely.
Once you have enough braids, it's time to start sewing them together to form a basket shape. Get a long length of doubled-over thread and knot it several times. Grab the tail of the braid and bring it up diagonally to form the bottom row of the basket. Push your needle and thread down through the base, then bring it over the braid and back down through the base to secure the bottom row. Keep repeating this process, pulling the thread tight to keep the braids in position, until you reach your desired size.
Finally, anchor the two layers of braids together and knot them on the inside of the basket. You can create curves in your basket by pulling the braids tighter or looser as you sew.
This process will result in a basket-weave texture on plastic, creating a non-slip surface.

Laser etch a texture
Laser etching is a popular technique used to create intricate designs and textures on plastic surfaces. It involves using a laser beam to etch patterns and designs onto the plastic surface, resulting in a high-contrast white image.
The first step in laser etching is to create a test table to determine the optimal work parameters. This step provides an understanding of the parameters that need to be chosen, and adjustments can be made based on the specific image or design. When the laser passes over the plastic surface, it leaves a white colour, so image inversion is often used to create the desired contrast.
Laser etching can be used to create various effects, from simple designs to more complex 3D textures. It is a precise process, with laser technology capable of achieving a precision of 0.01mm. This allows for refined and realistic patterns, enhancing the aesthetic quality of the plastic surface.
One of the benefits of laser etching is its ability to improve the appearance of the plastic by covering defects such as shrinkage and weld lines. It also increases the surface hardness, preventing scratches and providing a good tactile feel. Additionally, laser etching can create matte surfaces to reduce glare and eye fatigue.
Laser etching is a versatile process that can be applied to various plastic types, including PLA plastic and acrylic. It is a safe and effective method for creating non-slip textures on plastic surfaces, providing a durable and long-lasting solution.

Use textured paint
If you're looking to add some grip to a plastic surface, one option is to use textured paint. This can be an effective and affordable solution, especially for high-traffic areas or surfaces that become slippery when wet.
There are a few ways to achieve this, and one common method is to mix sand with paint. This creates a gritty, traction-enhancing mixture that can be applied to a variety of surfaces, including plastic. It's important to use the right kind of sand, as beach sand or sandy soil from your backyard may contain impurities that will affect the paint's consistency and performance. Instead, opt for play sand, which is clean and coarse enough to provide good traction. The ratio of paint to sand is important, and a good rule of thumb is four parts paint to one part sand. Allow the painted surface to cure for 24 hours, and then consider applying a second, sand-free coat to minimise the appearance of dark spots caused by the sand.
For a seamless, spotless finish, you can skip the sand altogether and mix a clear plastic grit, such as Seal Krete Clear-Grip, into your paint. This will add traction without affecting the colour or appearance of the paint.
If you're painting a plastic surface, it's important to prepare the surface properly to ensure the paint adheres well. Start by cleaning the plastic thoroughly to remove any oils or residue. Lightly scuff the surface with sandpaper, which will help the paint stick and reduce the amount of primer needed. Apply a couple of light coats of an adhesion promoter, followed by layers of a high-fill sandable primer. Sand between each layer, and then apply your paint, adding multiple coats and wet-sanding after each layer. Finish with a couple of coats of clear sealant.
There are also anti-slip floor paints available that are designed to provide a textured, non-slip surface. These are typically washable and durable and can be used on interior wood and concrete floors in high-traffic areas.
