What You'll Learn
Use a permanent marker
Using a permanent marker is a simple and effective way to write on black plastic. Here are some steps to ensure the best results:
Prepare the Plastic Surface:
Start by ensuring the plastic surface is clean and free of any grease, fingerprints, or other residue. Use a mild cleaning agent such as soap and water, or an alcohol-based solution to wipe down the plastic. You can also use a slightly acidic cleaner like lemon juice or vinegar, being careful to rinse the surface afterward. This step is crucial as grease and oil can prevent the marker from adhering properly.
Choose the Right Marker:
Select a high-quality permanent marker, preferably a new one with a good brand reputation. Avoid using old markers as they may not produce the desired results. Oil-based markers, such as Sharpies, are ideal for plastic surfaces and provide a glossy finish. They are also known to have better adhesion and longevity compared to traditional permanent markers.
Sand the Surface (Optional):
If you want to ensure maximum adhesion, you can lightly sand the plastic surface. Sanding creates microscopic holes for the ink to sink into, improving its longevity. However, this step is optional and may not be necessary for all projects.
Write and Allow Drying Time:
Once the surface is prepared, carefully write your desired text or design using the permanent marker. After you're finished, let the ink dry for several hours. During this time, avoid touching or handling the marked area to prevent smudging.
Apply a Sealant (Optional):
To further protect your writing, consider applying a sealant. Clear nail polish, mod podge (a type of decoupage glue), or clear packing tape can be used as a protective coating. These sealants will help prevent smudging, fading, and scratches, ensuring your writing lasts longer.
By following these steps, you can effectively use a permanent marker to write on black plastic. Remember that even with a permanent marker, the ink may fade over time, especially if the plastic surface is frequently handled or exposed to the elements. Regularly inspect your writing and be prepared to re-write or touch up the ink as needed.

Prepare the plastic surface
To prepare the plastic surface, it is important to ensure that the plastic is thoroughly cleaned and free of any grease, oil, or dirt. Start by scrubbing the plastic with soap and water, or using alcohol to clean the surface. You can also use a specific plastic cleaner if you have access to one. This step is crucial because any grease or oil on the plastic will cause the marker to not adhere properly and will result in your writing fading or rubbing off quickly.
Once the plastic is clean and dry, inspect the surface to ensure there are no remaining marks or spots that could interfere with your writing. Pay close attention to any rough spots or areas that might need light sanding to create a smooth and even surface for writing. You can use fine-grit sandpaper for this purpose, being careful not to scratch or damage the plastic.
If you're working with a new piece of plastic, it's a good idea to test a small area first to ensure that your marker will work well with the plastic. Choose an inconspicuous spot and try writing on it to see if the ink adheres properly and dries without any issues. This is especially important if you're using a new type of marker or a different brand of plastic.
For best results, it is recommended to use a new permanent marker that is known to work well on plastic surfaces. While regular permanent markers can be used, they may not provide the desired level of durability and longevity. Look for markers specifically designed for writing on plastic, such as the Sharpie Oil-Based Paint Markers or the STAEDTLER permanent markers with a medium 1mm point tip. These markers are designed to withstand harsh weather conditions and provide fade-resistant ink.
Additionally, consider the colour of the marker you intend to use. While black markers are widely available and suitable for writing on black plastic, you may also opt for other colours that can create a contrasting appearance. White, silver, or gold markers, for example, can produce visible writing on black plastic surfaces.

Clean the plastic
To write on black plastic, it is important to first clean the plastic surface thoroughly. This is to ensure that your writing adheres to the plastic and does not fade or rub off prematurely. Here is a detailed guide on how to clean the plastic before writing on it:
Prepare the Plastic Surface:
Start by inspecting the plastic surface for any contaminants, such as oily fingerprints, grease, dust, or dirt. These impurities must be removed to ensure a clean writing surface. Use a microfiber cloth to wipe down the plastic, removing any visible dirt or grease. If the plastic has rough spots or imperfections, you may need to lightly sand the area to create a smooth surface.
Clean with Soap and Water:
Mix a mild soap with warm water to create a soapy solution. Dip a clean cloth or sponge into the solution and wring it out to remove excess water. Gently wipe down the entire plastic surface with the damp cloth, ensuring you cover every inch. This will remove any remaining grease or dirt. You can also use alcohol or a specialised plastic cleaner for a more thorough clean.
Rinse and Dry:
Once you have finished cleaning with soap, rinse the plastic surface with clean water to remove any soap residue. Use a fresh cloth or sponge to wipe away the water, ensuring the plastic is completely dry. You can also let the plastic air-dry naturally if time permits. It is crucial that the plastic is entirely dry before you start writing on it.
Prepare the Area:
Before you begin writing, prepare your workspace by laying down newspaper or a drop cloth to protect surrounding areas. Gather all the necessary materials, including your chosen writing instrument and any protective gear, such as gloves or a face mask, if necessary. Ensure the plastic surface is still free of dust or debris right before you start writing.
Sealant Application (Optional):
If desired, you can apply a thin coat of sealant to the plastic surface before writing. Sealants provide extra protection and can help your writing last longer. Clear nail polish or a crafting sealant like modge podge can be used for this purpose. Allow the sealant to dry completely before proceeding with your writing project.
By following these steps, you will effectively clean and prepare the black plastic surface for writing. This will ensure that your writing adheres well and lasts for a more extended period without rubbing off.

Sealant application
Prepare the Plastic Surface:
Start by thoroughly cleaning the black plastic surface with alcohol, soap, and water to remove any dirt, grease, or fingerprints. Ensure that the surface is completely dry before proceeding. You may also need to sand the plastic lightly to smooth out any rough spots and create a more even surface for the sealant to adhere to.
Choose the Right Sealant:
The choice of sealant depends on the type of plastic you are working with. Different plastics have varying levels of compatibility with sealants. Common plastics like polyethylene and polypropylene can be challenging to work with and may require specific sealants like polyolefin adhesives. If you are working with PVC, silicone or epoxy sealants are good options. Silicone sealants offer flexibility, durability, and resistance to temperature changes, making them suitable for waterproofing and sealing joints. Epoxy sealants, on the other hand, provide a robust bond and chemical resistance, making them ideal for load-bearing applications.
Test Adhesion:
Before proceeding with the sealant application, it is crucial to test the adhesion on a small area of the plastic. This ensures compatibility and effectiveness. Refer to the manufacturer's guidelines and recommendations for specific instructions and precautions. Environmental factors, such as temperature fluctuations and humidity, can also impact the curing time and bonding strength of the sealant.
Apply the Sealant:
Follow the manufacturer's instructions for the chosen sealant's application technique and delivery system. Sealants come in various forms, such as cartridges that require a caulking gun or tubes with plungers that need to be mixed before application. Ensure you understand the curing time to plan your project efficiently.
Allow for Curing:
Sealants require time to cure and form a strong bond with the plastic. Refer to the manufacturer's instructions for the expected curing time and plan your project accordingly. Effective sealants cure within a reasonable timeframe, allowing for timely project completion.
By following these detailed steps for sealant application, you can ensure that your writing on black plastic is protected and durable. The choice of sealant and adherence to application techniques are crucial for achieving the desired results.
