You can put several things over an acrylic painting to protect it and enhance its appearance, primarily some form of varnish or sealer. The best choice depends on the desired finish and the specific needs of the artwork.
Here's a breakdown of common options:
Acrylic Varnish Options
- Acrylic Resin Varnish: This is a popular choice for a durable and archival finish. It offers good protection against UV light, dust, and moisture. Resin varnishes are typically removable for conservation purposes, allowing for cleaning and re-varnishing in the future.
- Acrylic Polymer Varnish: A good alternative to resin varnishes, offering similar protective qualities. Polymer varnishes are also usually removable.
Sealers
- Clear Sealer: These sealers can add a layer of protection against moisture and dust.
- Mod Podge: While primarily known as a decoupage adhesive, Mod Podge can also be used as a sealer. It is available in various finishes (gloss, matte, satin). It should be noted that Mod Podge can sometimes yellow over time and may not be as archival as dedicated varnishes.
Considerations When Choosing a Finish:
- Desired Sheen: Varnishes and sealers are available in gloss, matte, and satin finishes. Gloss enhances colors, while matte reduces glare. Satin offers a balance between the two.
- Removability: If archival quality and long-term conservation are important, choose a removable varnish.
- UV Protection: If the painting will be exposed to sunlight, select a varnish with UV protection to prevent fading.
- Application: Varnishes can be applied with a brush or spray. Spray varnishes often provide a more even finish.
In summary, acrylic resin varnishes, acrylic polymer varnishes, clear sealers, and Mod Podge are all viable options for finishing an acrylic painting. Choose the product that best suits your artistic goals and the specific needs of your artwork.
