20 Best Sealer For Diamond Painting (2023 Updated)

Diamond painting is a craft where small, faceted beads are applied to a sticky canvas to create a design. The beads are usually made of resin, and the most common colors are clear and white.

Sealer is used to protect the diamond painting from dirt, dust, and moisture. It can also be used to add a glossy or matte finish to the painting.

Wipe in a circular motion with a clean cotton towel or cloth to remove any excess sealer. If excess sealer dries on the surface, spray more sealer and wipe off immediately with a clean cotton towel. Allow 4-6 hours for the surface to completely dry.

Conclusion

The conclusion of a sealer for diamond painting should protect your work from dirt and moisture. It should be applied in a thin layer over the entire painting to keep the colors vibrant and the diamonds securely in place.
