What You'll Learn
Use a permanent marker with oil-based ink
To write on plastic cups permanently using a permanent marker with oil-based ink, you can use a Sharpie, which is a well-known and reliable brand with a variety of tip sizes, colours, and textures. Their fine-point tip permanent marker is highly recommended for plastic items, and it comes in a package of four. This marker works well on most plastics, including water bottles, sports equipment, playground toys, and camping gear.
It is important to note that not all permanent markers will work on plastic without smearing or fading over time. Traditional alcohol-based Sharpies, for example, will smear and eventually lose their colour. Therefore, it is best to use oil-based markers, which can be used on various surfaces such as metal, wood, rubber, glass, and stone, in addition to plastic.
To ensure that the ink adheres to the plastic surface, you can prepare the plastic by oxidizing it first. This can be done by passing the plastic past a flame, such as a candle or a small propane torch, being careful not to melt or discolour the plastic. Then, write on the flame-treated area with the permanent marker, and the ink should resist coming off.
Additionally, you can use a hairdryer or a heat tool to set the ink and make it permanent. After writing on the cup, apply heat to the area to help the ink dry and prevent smearing. It is recommended to let the ink dry thoroughly for 24 hours before using the cup.

Prepare the plastic surface with fine-grit sandpaper
To permanently write on plastic cups, it is important to prepare the plastic surface before you begin. Using fine-grit sandpaper, gently remove any shiny surfaces from the plastic cup. Be careful not to press too hard to avoid scratching the surface. The goal is to create a non-porous surface that will allow your paint or ink to adhere better. Once you have finished sanding, use a soft, clean brush or cloth to remove any dust from the cup.
It is important to note that even with this preparation, some types of ink may still smear or fade over time when applied to plastic. To improve the adhesion of your chosen writing instrument, you can try additional preparation methods. For example, you can use a candle or a small propane torch to lightly "burn" the surface of the plastic. Be careful not to hold the flame in one place for too long, as you do not want to melt or discolour the plastic. This oxidation process will help the ink stick better to the plastic surface.
Another method to ensure the ink adheres to the plastic is to use hairspray. After writing on the cup, spray a light mist of hairspray over the area. Once the hairspray is completely dry, you can paint on a top coat for added protection. Keep in mind that even with these additional steps, the ink may still smear, so it is important to be gentle and avoid going over the area too many times.
Once you have prepared the plastic surface, you can choose a suitable writing instrument. Permanent markers, such as Sharpies, are a popular choice for writing on plastic. Look for oil-based or paint-based markers, as these tend to work better on plastic than traditional alcohol-based markers. You can also use acrylic paint markers, which provide excellent opaque coverage and are easy to control, allowing you to create detailed designs.
After writing on the prepared plastic surface, you can further ensure the permanence of your design by applying heat. Use a heat tool from a craft store or a hairdryer to set the paint or ink. This will help to prevent dripping and ensure that your design lasts. Allow the design to dry thoroughly for at least 24 hours before using the cup.

Use acrylic paint markers
Acrylic paint markers are a fantastic option for writing on plastic cups. They provide a more opaque and vibrant colour than standard permanent markers and can be used to create intricate designs or bold artwork. Here is a step-by-step guide on how to use acrylic paint markers to write on plastic cups permanently:
Step 1: Choose the Right Marker
Select a suitable acrylic paint marker that is designed for use on plastic surfaces. Ensure that the marker has a fine tip for detailed writing and vivid details. Acrylic paint markers are filled with actual acrylic paint, which provides excellent opaque coverage and is permanent.
Step 2: Prepare the Cup Surface
Before you start writing, clean the plastic cup with soap and water or rubbing alcohol to remove any dust, oil, or residue. This step is crucial as it ensures that the paint adheres well to the surface. Use a cotton wipe to apply the rubbing alcohol, effectively removing any residual oils from the plastic.
Step 3: Test and Prepare the Marker
Before writing on the cup, shake the acrylic paint marker to mix the paint inside thoroughly. Then, press the tip of the marker on a piece of paper until it is saturated with paint. This step ensures a smooth and consistent ink flow while drawing.
Step 4: Write and Design
Now, you are ready to write on the cup! Draw directly on the plastic cup, carefully applying an even layer of paint. If you want a more intense colour, you can add more layers. Acrylic paint markers allow you to create intricate designs, bold artwork, or even add small details such as names or personalised messages.
Step 5: Drying and Sealing
Allow the paint to dry completely before using the cup. You can speed up the drying process by applying heat with a hair dryer or a heat tool from a craft store. For added durability, you can seal your design with an acrylic spray sealer or Mod Podge. Place the cup on a protected surface in a well-ventilated area, and lightly spray the sealer over the entire surface. Let the sealer dry completely before using the cup.
Tips and Tricks
- Always test your marker or paint on a small section of the cup first to ensure it adheres and dries well.
- If layering colours or adding details, let each layer dry completely before adding more to prevent smudging.
- Hand-wash the cups to prevent the design from fading or wearing off over time.
- To create a simple design, trace a printed or drawn design on a piece of paper and attach it to the inside of the cup with masking tape.
- If you want your design to be dishwasher-safe, use Dishwasher-Safe Mod Podge as a sealer.
By following these steps and tips, you can permanently write on plastic cups using acrylic paint markers, creating unique and impressive designs that will surely stand out!

Try a pen with paint instead of ink
If you want to write on a plastic cup permanently, one option is to use a pen with paint instead of ink. Acrylic paint markers are ideal for this purpose because they are easy to use, especially for those who are not confident with paintbrushes. Acrylic paint markers are similar to pens and are easy to control, and the fine tips allow you to create vivid details. Unlike ink markers, these pens are filled with acrylic paint, which provides excellent opaque coverage. The paint is also permanent. Before using an acrylic paint marker, allow the paint to flow to the tip of the marker by pressing the tip firmly on a piece of paper until it is saturated.
There are a variety of paint markers available in the market, such as the Zeyar paint markers, which come in 24 different colours and dry quickly. The Sharpie brand also offers oil-based paint markers that can be used on plastic and other surfaces such as metal, wood, rubber, glass, and stone.
It is important to note that not all permanent markers will work on plastic surfaces without smearing or fading over time. To ensure that your writing stays on the plastic cup, you can prepare the plastic surface by removing any shiny surfaces with fine grit sandpaper. Then, use a soft, clean brush or cloth to remove any dust. You can also try oxidizing the surface by passing it briefly over a flame, being careful not to melt or discolour the plastic.
Once you have prepared the surface, you can use your paint pen to write on the cup. After you have finished writing, you can apply heat to the paint to help it dry and become permanent. You can use a hairdryer or a heat tool from a crafts store for this purpose. It is recommended to let the paint dry for 24 hours before using the cup.

Use a heat tool or hair dryer to set the ink or paint
Using a heat tool or hair dryer to set the ink or paint is an effective way to ensure your design becomes permanent. This method is especially useful when using acrylic paint markers, as the heat will help to set each layer of paint and prevent colours from blending.
Firstly, you will need to prepare your work area. Ensure you are in a well-ventilated area, and cover any surfaces to protect them from paint or heat damage. Have your plastic cups ready, along with your chosen paint or ink, a heat tool or hair dryer, and any other necessary supplies, such as paintbrushes or stencils.
If you are using paint, it is important to allow each layer to dry before applying heat. Hold the heat tool or hair dryer several inches away from the cup, and apply heat to the painted area until the paint is completely dry. You can then move on to the next section or colour, repeating the process until your design is complete.
Even if you are not using paint, applying heat to the ink or paint on the plastic cup will help to set it and make it permanent. Simply use your hair dryer or heat tool to apply heat to the design, being careful not to get too close to the cup to avoid melting or discolouration.
Finally, allow your design to dry and set for 24 hours before using the cup. This will ensure that the paint or ink is completely dry and will not smudge or fade over time.
