How to Seal Joint Compound Art

Creating artwork with joint compound can be a unique and creative way to express yourself. Joint compound, also known as drywall mud, is typically used for repairing and finishing drywall surfaces. However, it can also be used as a medium for creating textured and sculptural artwork. Once your joint compound art is complete, it’s important to seal it properly to protect it from damage and ensure its longevity. In this article, we will guide you through the process of sealing joint compound art and answer some common questions about this technique.

Sealing Joint Compound Art:

2. Clean the surface of the artwork using a soft brush or cloth to remove any dust or debris.

3. Decide on the type of sealer you want to use. There are various options available, including acrylic sealers, clear varnishes, and epoxy resin. Each has its advantages, so choose the one that best suits your needs.
