Now, you’ve finally finished your gorgeous diamond painting. Every diamond is finally filled, and you are admiring your creation and how to seal it is the next question pop up in your mind.

Despite your long hours of work, your job is not finished yet. Now, you need to further refine your masterpiece. That’s when we get to the last step of the diamond painting process: sealing.

Diamond beads can often fall off the canvas over time. The only way to prevent this is to use a sealant. The sealant can also stiffen up your painting, giving it some structure. This can make it easier to mount somewhere and store it without damaging the painting.

In this article, we will outline some techniques to help you through the final process of sealing your diamond painting.

If you haven’t reached the final step yet and have just started out, then check out some of these handy diamond painting techniques or discover more on our blog post  Diamond Painting - Everything you need to get started


Step 1 - The essentials

Here are a couple of the materials you’ll be needing to put on the sealant:

  • Sealer Glue/Finish (or a Sealer Spray, Gloss Modge Podge )
  • Paint Brush
  • Roller
  • Toothbrush (or cloth)
  • Tweezers

If you feel confused about where to get these important tools, we highly recommend that you take a look at the Diamond Painting Tools Full Kits. They provide you with the supplies that you'll need in every stage of your diamond painting process, from setting up the beads to refining it with the sealer. 

The type of sealant you get is up to you. However, we recommend a glue that remains clear upon drying as the type of glue you use could make your diamonds appear less shiny. Feel free to experiment with different glues!

Step 2 - Preparation

  1. Remove air bubbles between the diamonds. Using your roller, press firmly but gently onto all sections of the diamond painting. 
  2. Remove the extra wax and dust particles between the diamond beads. You can do this by first scrubbing a toothbrush or using a fuzzy cloth to get in between the cracks. 
  3. Further, refine the details by using a pair of tweezers.

Step 3 - Applying the Sealant

There are different types of sealants and techniques, and you can choose whichever you prefer!  
  • Glue paste. Dip your paintbrush in the glue and paint a generous layer on top of your painting - but not too much, as it could reduce the shine of your painting.
  • Glue sticks. Apply this type gently and completely cover the painting, adding on layers until you’re satisfied.
  • Spray glue. Simply use short bursts and spray 2-3 times in distinct areas of your painting.

More tips and tricks

  • If your painting has both diamond beads and regular paint, then put the glue only over the diamond beads. Once you're done with the first layer, apply a second or third until you’re satisfied. Make sure you don't apply too much, it will dull the sparkle of your diamond painting.
  • Make sure you’re satisfied with the end product! Remember, what you see is what you will get. Once you put on the sealant, there’s no going back, so you have to make sure that your masterpiece looks perfect.
  • Examine your painting for any rogue pixels that feel out of place or don't match the overall color scheme. This is your artwork after all, and you get to decide what looks good and what doesn’t!
  • If you’re afraid of how your painting might look with the finish, try putting the glue over a small section of your diamond painting. You can also try a different one and then compare and contrast from there.


Most glues will only be effective for a certain period of time, therefore you’ll have to repeat this process every 3 years or so.

Also, make sure you dust your painting often as dust can still get in between the cracks of your beads when on display for long periods of time.
