How to Seal Diamond Painting in 3 Easy Steps

How to Seal Diamond Paintings - 5D Diamond Painting Kits | Pretty Neat Creative

Now, you’ve finally finished your gorgeous diamond painting. Every diamond is finally filled, and you are admiring your creation and the next question pop up in your mind is should I frame it or seal it? What is the pros and cons of sealing? And how to seal it? Here are the answers:

Pros: Sealing your Diamond Painting will lock all of the diamonds in place and significantly increase the longevity of your finished project. Using the sealant can help to stiffen up your painting, giving it some structure. This can make it easier to mount somewhere and store it without damaging the painting. If you plan to hang your Diamond Painting or use Stretcher Bar to showcase it, it’s crucial you first seal your finished painting.  

Cons: sealants may sometimes warp the project, causing it to become misshapen. And, sealants can, over time, begin to turn yellow, giving the top coat an unappealing appearance. So, it’s really entirely up to your personal preference whether to seal or frame your masterpiece.

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.
  • Wanna see which sealer works? Keep watching this video below, Studio Sam has shared her experience:


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.

Diamond painting is relatively new in the world of the arts and craft. If you’re reading this, then you too are surfing on this new wave of popularity surrounding diamond painting. Don’t be afraid to get creative and make sure you’re having fun!

    My husband builds models and adds a coat of Future floor wax to preserve the paint. It never yellows and some of his models are over 20 years old! Would this work on diamond art because I’m not thrilled with the midge podge? Thank you

    • Lyna Dinh says:

      Hi Kimberley,
      We’ve never heard any diamond painters tried to use Future floor wax on diamond paintings but I think it also works. Please try to apply to a small area and see if it works well.
      Our experts usually use nail polish or Mod Podge glue.
