Alcohol ink is a fun and vibrant art medium that can be used on a variety of surfaces, including plastic. However, it is important to seal alcohol ink properly to prevent it from fading, scratching, or getting damaged over time. The sealing process involves three steps: allowing the ink to dry thoroughly, coating it to prevent interaction with varnishes, and protecting it from UV rays and physical damage. While there are many sealants available, such as Kamar Varnish, UV protective sprays, and resin, it is crucial to choose the right sealant to avoid ruining the artwork. Sealing alcohol ink on plastic requires careful ventilation and can enhance the artwork's finish and longevity.

What You'll Learn
Allow alcohol ink to dry for 24-48 hours before sealing
Alcohol ink is dye-based and will break down and fade over time. Therefore, it is important to seal alcohol ink properly. Before sealing, it is crucial to allow the alcohol ink to dry completely. This typically takes around 24 to 48 hours, although some sources suggest 72 hours to be safe. During this time, the ink should not be touched, as it needs to fully cure on the substrate it is on. If the alcohol ink has not completely dried, there is a risk that it may react with the sealant and cause unwanted results.
The drying time may vary depending on the humidity levels. If the humidity is high, it may take longer for the alcohol ink to dry. To prevent the accumulation of dust and lint particles during the drying process, it is recommended to cover the artwork with a plastic bin or lid that does not touch the surface. Additionally, ensure that the area is well-ventilated.
Once the alcohol ink has dried thoroughly, you can move on to the sealing process. Sealing alcohol ink involves applying a sealant to protect the artwork from scratches, damage, and fading. There are various sealants available, such as Kamar Varnish, UV protective sprays, and resin. The choice of sealant depends on the specific requirements of the project.
It is important to follow the instructions and take the necessary precautions during the sealing process to ensure the best results and protect your artwork.

Seal with Kamar Varnish
Sealing alcohol ink art with Kamar Varnish is a popular method, but it is not enough on its own for items that need to withstand heat and moisture, like coasters. It is, however, considered sufficient for wall art that will be framed and placed under glass.
Kamar Varnish is a synthetic artist varnish that offers protection similar to traditional damar but without the impurities and yellowing. It is best applied in temperatures between 55° F to 75° F and when humidity is below 60%. The varnish should be sprayed in a well-ventilated area, with 2-5 light coats, about 12-18 inches away from the artwork. Allow 30 minutes to an hour of drying time between layers, and 24 hours or more after the final coat.
Kamar Varnish is often used as the first step in a three-step sealing process for alcohol ink art. The second step involves applying a UV protective spray, like the Krylon Gallery Series UV Archival Varnish, to prevent the ink from fading due to UV exposure. The third step is an optional sealant for added protection and a glossier finish, such as the Krylon Acrylic Crystal Spray or the Rustoleum Engine Enamel.
While Kamar Varnish is a popular choice for sealing alcohol ink art, it may not be suitable for all projects. For example, it is not food-safe and should not be used on items that come into direct contact with food or the mouth, like mugs or dishes.

Seal with UV protective spray
Alcohol inks are dye-based and not light fast, so they will fade with time, especially with exposure to UV rays from sunlight. To slow this process down, your art must have UV protection.
Before applying a UV protective spray, ensure that the alcohol ink is fully dry. Allow at least 24 hours or more for the best results. It is also recommended to cover the artwork during drying time to prevent the accumulation of dust and lint particles in the air.
Once the ink is dry, you can apply the UV protective spray. Krylon makes an archival varnish in both matte and glossy finishes that will help make your art last longer. Apply 2-3 light coats, about 12-14 inches away from the artwork, allowing 30 minutes to an hour of drying time between layers. After the final coat, allow the UV protective spray to dry completely. This typically takes about 2 hours, but it may take longer depending on humidity levels.
If you are looking for a deeper glossy look, you can seal your alcohol ink with resin, such as Pro Marine Supplies Pro Art Epoxy Resin, which offers additional UV protection. However, working with resin can be more complicated and time-consuming.
It is important to note that the UV protective spray should not be applied directly to the painting, as it can cause the inks to move. Instead, spray a barrier layer of Kamar first, and then apply the UV protective spray.

Seal with resin for a glossy finish
Sealing alcohol ink art is crucial to prevent it from fading, chipping, reconstitution, and yellowing over time. Alcohol inks are dye-based and susceptible to breaking down and fading when exposed to ultraviolet light. Proper sealing techniques can significantly slow down this process.
Before applying any sealant, it is essential to allow the alcohol ink to dry completely. The drying time can vary, but it is typically recommended to wait for at least 24 to 48 hours, or even up to 72 hours, to ensure the ink is fully cured. Working in a well-ventilated area is also important.
One popular sealant option is resin, which can give your artwork a glossy and glass-like finish. When using resin, it is essential to follow the manufacturer's instructions carefully, as it has a learning curve. A generous flood coat of resin will create a glossy finish and enhance the colours of your artwork. Pro Marine Supplies Pro Art Epoxy Resin is a popular choice that offers additional UV protection and is food-safe once fully cured. It is important to note that resin can be expensive and time-consuming, requiring up to 72 hours to cure completely.
To achieve a glossy finish with resin, you can follow these general steps:
- Allow the alcohol ink to dry completely for at least 24 to 48 hours before starting the sealing process.
- Prepare your workspace in a well-ventilated area and cover your artwork with a plastic bin or lid to prevent dust accumulation during the drying process.
- Apply a flood coat of resin to your artwork, following the manufacturer's instructions for the specific resin product you are using.
- Allow the resin to cure completely, which can take up to 72 hours or more, depending on the product and environmental conditions.
- Once cured, your artwork will have a glossy and vibrant finish that will protect it for years to come.
