In the world of crafting and artistry, diamond painting has emerged as a captivating and therapeutic activity. Transforming small, sparkling resin “diamonds” into vibrant mosaic-style art pieces can be a relaxing and rewarding experience. However, to truly preserve and enhance these glittering works of art, the right sealer is crucial. In this comprehensive guide, we’ll explore the importance of diamond art sealers, the various types available, tips for choosing the perfect sealer, maintenance advice, and where to find the best sealers for your projects.

What Are Diamond Art Sealers and Why Do You Need Them?

Understanding Diamond Art Sealers

Diamond art sealers are specially formulated finishes designed to protect the completed diamond paintings. These sealers create a barrier on the canvas that helps secure the diamond drills, preventing them from loosening or falling off. They also provide a protective layer that can shield the art from dust, dirt, moisture, and UV rays, thereby ensuring the longevity of the piece.

The Importance of Using a Sealer

While diamond paintings can be striking when first assembled, they can lose their luster over time without proper sealing. The adhesive used to affix the tiny diamonds on to the canvas can degrade, especially in harsh environmental conditions. Sealers act as a shield, keeping your art looking new and vibrant, no matter where you choose to display it. Sealers come in a variety of different finishes so it is important the sealer matches the project.

Spray Sealers

Spray sealers are often a preferred choice due to their ease of application. They can provide a smooth and uniform finish over large areas quickly. The aerosol form also prevents brush strokes, which can be a noticeable flaw in the final piece.


  • Even coverage

  • Quick-drying

  • No brush marks


  • Can be difficult to control in smaller projects

  • The fumes may be too strong for some users

Brush-On Sealers

Brush-on sealers give you more control over the application and work well for smaller projects. With careful application, brush-on sealers can provide an even shine, gloss or matte finish, depending on the sealer type.


  • Precise application

  • Work well for detailed and small projects


  • Risk of brush strokes showing

  • Slower application process

Sealant Glues

Some crafters prefer using sealant glues, which are essentially strong adhesives that create a protective layer as they dry. They are more viscous than other types and may require some mixing or thinning with a solvent before use.


  • Strong bond

  • Can be layered to increase protection


  • Application can be messier

  • Potential for cloudy or uneven drying

How to Pick the Right Diamond Art Sealer for Your Project

Considering Your Painting’s Size and Detail

For larger projects hard work where speed is essential to maintain consistency of the finish, a spray sealer may be best. Conversely, smaller, more detailed works might benefit from a brush-on sealer for a controlled application without the risk of overspray.

Desired Finish and Environmental Factors

Consider the look you want for your piece – glossy, matte, or somewhere in between. Additionally, if your diamond painting will be exposed to higher levels of humidity or sunlight, a sealer that provides UV protection and is water-resistant would be wisest.

Application and Storage Tips

Whether you choose a spray or brush-on sealer, always test their compatibility with your diamond painting on a separate, similar surface. This ensures the sealer won’t affect the colors or adhesive of your artwork. Ensure the finished canvas and surrounding environment are clean, and free of dust and other particles that could become trapped in the sealer. Proper storage of the sealer can increase its shelf life, typically in a cool, dry place.

Protecting Your Finished Piece

Once your finished diamond painting part is sealed, handling it with care is crucial. Avoid creases, folds, and sharp impacts that could damage the protective layer or dislodge drills over time. Always use a clean, soft cloth to gently clean the entire painting when necessary. You spent so much time making a gorgeous piece of art don’t let time diminish its sparkle.

Long-Term Care and Preservation

To improve the longevity of your sealed diamond art, consider using all in one glue and framing it under glass. This provides an additional barrier against environmental damage and allows for safer and easier cleaning. If hanging, choose a display area away from direct sunlight and high humidity.

If you need to store your projects be sure to lay them flat and try to contain them between layers of mat board or cardboard to ensure the canvas doesn’t get creased. When removing from storage inspect the piece carefully to make sure all the diamonds are in place and none are loose.

Frequently Asked Questions (FAQ)

Can I use a regular varnish or sealer meant for other crafts on a diamond painting kit?

While varnishes or sealers designed for other crafts might work, it’s essential to choose products specifically for diamond painting sealer labeled as compatible with diamond painting to ensure the best results and avoid damaging your artwork.

How long should I wait before sealing my diamond art?

It’s advisable to wait at least 24 hours after completing your diamond art to ensure that the adhesive has fully set. This waiting period prevents smudging and ensures the drills stay in place during the sealing process.

Can I use a hairdryer to speed up the drying process of the sealer?

Using a hairdryer on a low, cool setting might help speed up the drying time, but be cautious. High heat or a powerful air stream can displace lightweight drills. Always test this method on a small, inconsequential area first. It is important for each layer to be completely dry but heat is not always your friend. Overheating can warp the canvas and cause individual diamonds to glaze over or turn milky.

How many layers of sealer should I apply?

This can vary depending on the type of sealer used and the level of protection desired. Generally, one to two coats are sufficient, but read the product’s instructions for specific recommendations. Allow each layer to dry completely before applying the next coat. This is especially true when using a brush on sealant. Sometimes a smaller brush will help avoid air bubbles and provide a perfect consistency for your piece.

Is it necessary to seal diamond art?

Sealing is not necessary for every project, but it is recommended for pieces you wish to preserve long-term. Sealing helps protect against dust, spills, and fading, especially if the artwork will be handled or displayed without glass protection.

Can sealed diamond art still be framed without glass?

Yes, sealed diamond art can be framed without glass, as the sealer provides a protective layer. However, framing under glass or acrylic adds another level of protection, especially from UV light and physical damage. Framing with glass is as much a matter of personal preference as it is a layer of protection.

Where can I find more advice on sealing diamond art?

Many online communities and forums dedicated to crafting and diamond painting offer extensive advice, personal experiences, and recommendations for sealing diamond art. Exploring these resources can provide valuable insights and creativity.
