Sharpies are alcohol-based markers with dye, not ink, which means they are not designed to last forever. The alcohol evaporates, leaving behind only the dye. However, there are specific Sharpie acrylic markers that feature paint-like ink. While these markers are designed to be used on a variety of surfaces, including paper, metal, wood, and glass, it is unclear whether they will work on acrylic plastic. To ensure that the marker ink adheres to a plastic surface, it is recommended to first sand the surface to create a rough texture. Additionally, an acrylic sealer spray can be used as a protective finish.

Sharpie ink can easily smear, rub off, and disappear on plastic
Firstly, it is important to clean the plastic surface to remove any oils or dirt. This can be done by gently rubbing the surface with a soft cloth dampened with warm water and mild dish soap. The surface should then be patted dry with a cloth. Next, the surface should be wiped with isopropyl alcohol and a cotton ball to ensure it is completely clean. Once the surface is dry, it can be sanded using fine-grained 120-grit sandpaper. Sanding the plastic creates a rough, porous surface, which allows the marker ink to adhere better.
After sanding, the plastic surface should be cleared of any particles and dust using a soft cloth. At this point, you can begin to write on the plastic with your Sharpie. It is recommended to test the marker on a scrap piece of paper first to ensure that the ink is flowing properly and to prevent any smudges or messy ink spills. Once you are happy with the ink flow, you can start writing on the plastic. Allow the marker ink to dry for a couple of hours.
To ensure the Sharpie ink does not smear or rub off, you can use an acrylic sealer spray for a protective finish. However, it is important to be cautious when using these sprays as they can have a strong odor similar to spray paint. It is recommended to use them in a well-ventilated area or outdoors and to wear a respirator mask and gloves for protection. Before spraying directly onto your plastic surface, test the sealer on a scrap piece of material or board. If using a Mod Podge acrylic spray sealer, hold it 6 to 8 inches away from the plastic and spray lightly. Allow the sealer to dry for 24 to 48 hours.
While the above method can help Sharpie ink stick to plastic, it is important to note that Sharpies are alcohol markers with dye, not ink. Alcohol markers are designed to eventually break down, with the alcohol evaporating over time and leaving behind the dye. Therefore, if permanence is required, it is recommended to use markers with pigment ink, such as Sakura Pigma Micron pens, or Posca paint pens, which are acrylic paint pens.

Sharpies are alcohol-based markers, which are not designed to last forever
Sharpies are alcohol-based markers that contain dye rather than ink. Alcohol markers are not designed to be permanent and will eventually fade. The alcohol in the marker evaporates over time, leaving behind the dye that provided the marker's colour. This means that Sharpie art can start to degrade anywhere between six months and five years after creation.
Sharpie ink can be preserved for longer by using a sealant. However, this does not always work. One source notes that they tried to seal their Sharpie art with polyurethane, but this caused the ink to bleed into the acrylic paint. Another source claims that UV sealants will not work on alcohol markers, but will work on paint.
If permanence is required, markers with pigment ink, such as Sakura Pigma Micron pens, should be used. These markers contain the same stuff that is in paint. Posca paint pens are another alternative that will last as long as acrylic paint.
Sharpie does sell a range of acrylic creative markers, which are designed to be permanent and can be used on a variety of surfaces, including paper, metal, wood, ceramic, glass, rock, and canvas. However, these markers have received mixed reviews, with some people claiming that the ink can be scraped off or washed off surfaces.

Permanent markers with pigmented ink are better for plastic than Sharpies
While Sharpies are a popular choice for permanent markers, they may not be the best option for plastic surfaces. This is especially true when it comes to acrylic plastic. Sharpies are alcohol-based markers with dye, not ink. Alcohol markers are not designed to last forever—the alcohol base evaporates, leaving behind only the dye. This means that Sharpies can break down anywhere between six months and five years.
On the other hand, permanent markers with pigmented ink are designed for permanence and can offer better results on plastic surfaces. Pigmented ink is water-resistant and can adhere to most surfaces, including plastic. Markers with pigmented ink, such as the Sakura Pigma Micron pens, contain the same ingredients as paint, ensuring a longer-lasting mark.
To improve the adhesion of any marker on a smooth plastic surface, you can prepare the surface by cleaning it with soap and water, then isopropyl alcohol, and finally sanding it with fine-grained sandpaper. This gives the plastic a slightly rough texture that allows the marker ink to adhere better.
While Sharpies can work on plastic in certain conditions, they are not the ideal choice for long-lasting results. For the best permanence on plastic, it is recommended to use markers with pigment-based ink. These markers will provide brighter and more vibrant colours that will firmly stay on plastic.

Sanding plastic with sandpaper can help Sharpie ink adhere to the surface
Sharpies are alcohol-based markers with dye, not ink. They are designed not to last forever as the alcohol evaporates, leaving behind the dye. However, there are ways to make Sharpie ink last longer on acrylic plastic surfaces.
Firstly, it is important to prepare the plastic surface by cleaning it with soap and water, or alcohol, to remove any dirt, grease, or oils. This ensures that the Sharpie ink will not smear or rub off easily. Once the surface is clean, it should be allowed to dry.
Sanding the plastic surface with sandpaper is a crucial step in helping the Sharpie ink adhere better. Fine-grained sandpaper with a grit size between 80 and 120 is recommended. This process creates a slightly rough and porous texture on the smooth plastic surface, which allows the marker ink to stick better and prevents smearing. After sanding, use a soft cloth to wipe away any dust or particles left on the surface.
While sandpaper helps create a better surface for the Sharpie ink to adhere to, it is important to note that the Sharpie marker used should be of good quality and preferably new. Older markers may not work as effectively, and cheaper options may require more sealant. Additionally, testing the marker on a different surface first is recommended to ensure it is working well.
After sanding and preparing the plastic surface, you can start writing with the Sharpie. Once the ink has dried, you can further protect it by applying a light layer of Mod Podge glue or clear packing tape over it. These methods help seal and protect the Sharpie ink, preventing it from smearing or rubbing off easily.

Spray sealants can be used to protect Sharpie ink on plastic
Sharpies are alcohol-based markers with dye, which means they are not designed to last forever. The alcohol in the marker evaporates, leaving behind the dye, which can easily smear, rub off, and disappear over time. However, with proper preparation, you can make Sharpie ink last longer on plastic surfaces.
Before writing on the plastic surface, it is important to clean and prepare the surface. Use a damp cloth with warm water and mild dish soap to remove any dirt, oils, or grease spots. Once the surface is clean, sand it using fine-grained sandpaper (120-grit) to create a slightly rough, porous surface that allows the marker ink to adhere better.
After preparing the surface, choose the right type of markers. Oil-based markers, such as Sharpie Oil-Based Paint Markers, are ideal for use on plastic as they resist fading and smearing. Traditional alcohol-based Sharpie markers are not recommended for plastic as they will smear and fade over time.
Once you have created your artwork, let the ink dry completely, preferably overnight. Then, you can apply a sealant to protect the Sharpie ink and make it last longer. Spray sealants, such as acrylic sealer spray, Aleene's sealer spray, or Sharpie fixative spray, can be used for this purpose. These sprays create a protective finish that seals and protects the ink from fading, smearing, or yellowing.
When using a spray sealant, it is important to follow certain precautions. Firstly, test the spray on a scrap board or material before applying it directly to your artwork to avoid any smears, ink pooling, or colour changes. Secondly, spray in a well-ventilated area or outdoors as these sprays can have a strong odour. Finally, hold the item away from you and spray lightly and continuously to avoid thick and uneven applications.
In addition to spray sealants, there are other DIY alternatives such as transparent nail polish or Mod Podge, which can be applied by spraying or brushing on the surface. These alternatives also help protect the Sharpie ink and add a shiny or matte finish to your artwork.
