How to Seal Diamond Painting with Hairspray?

Diamond painting is a popular and relaxing craft that involves placing small, colorful resin diamonds onto a canvas to create a stunning piece of art. Once you’ve completed your diamond painting masterpiece, it’s essential to seal it to protect the diamonds and preserve the vibrant colors for years to come. 

While there are various sealers available, using hairspray as a sealer is a cost-effective and accessible option.

What is Diamond Painting?

Before we delve into the sealing process, let’s briefly understand what diamond painting is. Diamond painting is a form of mosaic art that uses resin diamonds or drills to create a beautiful, sparkly image. It’s similar to paint-by-numbers, but instead of using paint, you place small, faceted diamonds on the canvas according to the provided pattern.

Why Seal Diamond Painting?

Sealing your completed diamond painting is essential for several reasons. Firstly, it protects the diamonds from falling off the canvas, especially if you plan to display or hang your artwork. Secondly, sealing creates a barrier that prevents dirt, dust, and other contaminants from accumulating on the surface. 

Thirdly, it enhances the overall appearance of the painting, making it look polished and professional.

Preparing the Diamond Painting for Sealing

Before applying any sealer, it’s crucial to prepare the diamond painting properly. Start by cleaning the surface of the canvas using a soft, lint-free cloth. This will ensure that no dust or debris gets trapped under the sealer. Additionally, check for any loose or excess diamonds and carefully remove them to achieve a smooth surface.

Using Hairspray as a Sealer for Diamond Painting

Hairspray can be a suitable option for sealing diamond paintings, but not all hairsprays are created equal. Look for a hairspray that is non-sticky, clear, and provides a strong hold without making the diamonds foggy or dull. 

Before applying the hairspray to the entire painting, do a small test on a corner or less noticeable area to ensure it won’t damage the diamonds or canvas.

Applying Hairspray to the Painting

Once you’ve selected the right hairspray, apply it evenly to the entire surface of the diamond painting. Hold the can at least 12 inches away from the canvas to avoid overspraying or causing the diamonds to become sticky.

 Apply thin and even coats, allowing each coat to dry completely before applying the next one. This will prevent any smudging or clumping of the diamonds.

Alternative Sealers for Diamond Painting

While hairspray can work as a sealer, there are other options to consider. Clear acrylic varnish is a popular choice among diamond painters as it provides a protective and glossy finish. Mod Podge, a versatile craft glue, can also be used as a sealer, and it dries clear to keep the diamonds looking vibrant and finished.

Tips for a Successful Sealing Process

To ensure the best results when sealing your diamond painting, consider the following tips:

  • Apply thin and even coats of the sealer to avoid any clumps or smudges.
  • Allow each coat to dry completely before applying the next one.
  • Avoid over-spraying, as excessive sealer can cause the diamonds to lose their sparkle.
  • Don’t forget to seal the edges of the canvas to prevent the diamonds from falling off.

Protecting the Hairspray-Sealed Diamond Painting

Once you’ve successfully sealed your diamond painting, it’s essential to take proper care to protect it for the long term. Store the painting in a clean, dry, and temperature-controlled area to avoid any damage caused by environmental factors. If you plan to display the painting, frame it with glass to provide extra protection against dust and UV rays.


Sealing your diamond painting is a crucial step in preserving its beauty and ensuring its longevity. Hairspray can be a budget-friendly and effective option for sealing, but it’s essential to choose the right type and apply it correctly. 

Alternatively, clear acrylic varnish and Mod Podge are reliable alternatives. Whichever method you choose, proper sealing and care will allow you to enjoy your sparkling diamond painting for years to come.


It’s best to use a non-sticky, clear hairspray with a strong hold to avoid any damage to the diamonds or canvas.

Apply thin and even coats of hairspray, allowing each coat to dry completely before applying the next one.

If you apply the hairspray correctly, it should not make the diamonds sticky or dull their sparkle.

It’s advisable to test the hairspray on a less noticeable area first to ensure compatibility with special finishes.

Hairspray may not be suitable for diamond paintings with fabric elements, as it can cause discoloration or damage to the fabric. Consider using an alternative sealer like clear acrylic varnish or Mod Podge.
