How to Seal Diamond Painting with Double-Sided Tape?

Diamond painting is a captivating and rewarding craft that allows enthusiasts to create stunning works of art using small, colorful resin diamonds. Once the diamond painting process is complete, sealing the artwork becomes crucial to ensure the diamonds stay firmly in place and the painting maintains its beauty over time. 

While many sealing methods exist, one popular and effective option is using double-sided tape. In this article, we will explore how to seal diamond painting with double-sided tape, the benefits it offers, and the various techniques for achieving a secure and long-lasting seal.

Preparing Your Diamond Painting

Before sealing your diamond painting, it is essential to ensure that all diamonds are securely attached to the canvas. Double-check for any loose diamonds and gently press them down to guarantee a strong adhesion. Additionally, clean the surface of the canvas to remove any dust or debris that could interfere with the sealing process.

Understanding Double-Sided Tape

Double-sided tape is a versatile adhesive that features adhesive on both sides. It is available in various sizes and thicknesses, making it suitable for different diamond painting projects. When using double-sided tape for sealing, it is essential to choose the right type that adheres well to your canvas material and is compatible with the diamonds.

Applying Double-Sided Tape

Before applying the tape, select the appropriate type based on the canvas material and the diamonds’ size. Cut the tape into strips or shapes that match the area you want to seal. Remove the protective backing from one side of the tape and carefully place it on the canvas, making sure it aligns with the diamonds’ edges.

Sealing Techniques

There are several techniques for using double-sided tape to seal diamond paintings. The most common methods include the complete coverage method, the border-only method, and the diamond-by-diamond method. Each technique offers a different level of coverage and flexibility.

The complete coverage method involves placing the tape over the entire diamond painting, creating a secure and uniform seal. The border-only method focuses on sealing only the edges of the canvas, leaving the center area unsealed. The diamond-by-diamond method entails applying small pieces of tape directly beneath each diamond, ensuring individual adhesion.

Tips for a Neat and Effective Seal

To achieve a neat and effective seal, consider using a roller to ensure the tape adheres smoothly to the canvas. When handling and adjusting diamonds during the sealing process, use a gentle touch to avoid displacing the gems. Be mindful of overlapping or leaving gaps between the pieces of tape, as these may compromise the seal’s integrity.

Additional Decorative Options

While double-sided tape provides a secure seal, it also offers opportunities for creativity. You can enhance your diamond painting by adding glitter or other embellishments along with the tape. Additionally, experimenting with colored double-sided tape can add a unique touch to your artwork.

Caring for Your Sealed Diamond Painting

Properly caring for your sealed diamond painting is crucial for maintaining its longevity. Store the artwork in a cool, dry place to prevent damage to the adhesive. When displaying the sealed diamond painting, avoid direct exposure to sunlight or high humidity to preserve the gems’ brilliance and adhesion.

Common Mistakes to Avoid

Using the wrong type of double-sided tape or not applying it correctly can lead to an ineffective seal. Avoid using tape that does not adhere well to your canvas material, as it may result in diamonds coming loose. Applying excessive pressure while sealing can also damage the canvas or cause diamonds to pop off.

Advantages of Using Double-Sided Tape

Double-sided tape offers several advantages for sealing diamond paintings. It is a quick and easy application process that does not require any drying time. This adhesive option is also reversible, allowing you to reposition diamonds if needed without damaging the canvas.

Comparing Double-Sided Tape to Other Sealing Methods

When considering sealing options, it is essential to compare double-sided tape to other popular methods, such as glue and sealant sprays. While each method has its merits, double-sided tape stands out for its ease of use, quick application, and repositioning capability.

Addressing Concerns About Double-Sided Tape

Some concerns may arise when using double-sided tape for sealing diamond paintings. It is essential to address these concerns to ensure users have a complete understanding of this sealing method. For instance, questions about potential damage to the canvas or the tape’s holding power in high humidity environments can be addressed.


Sealing your completed diamond painting is a vital step to preserve its beauty and ensure the diamonds stay in place for years to come. Double-sided tape provides a practical and effective solution for sealing, offering quick application and a strong hold. By following the proper techniques and tips, your sealed diamond painting will become a cherished masterpiece, ready to be proudly displayed or gifted to loved ones.
