For the past 3 months, you've donated every spare waking moment (and moments where you should have been sleeping) to placing thousands of tiny diamonds in little squares. 

And now, like magic, you stand back and marvel at a gorgeous Diamond Painting of your own making.

Shine on, you crazy Diamond Painting

As time goes on, you'll want your Diamond Painting to look and feel as gorgeous as the day you finished it. So what can you do to keep your artwork perfect for years to come? 

How To Seal Your Finished Diamond Painting

Sealing your Diamond Painting will lock all of the diamonds in place and significantly increase the longevity of your finished project. 

If you plan to hang your Diamond Painting or use Stretcher Bars to showcase it, it's crucial you first seal your finished painting.  

Brush-On Sealers 

Brush-On Sealers present an all-in-one solution to preserving your Diamond Painting for years to come. They come in a variety of finishes and consistencies depending on your personal preference. 

Pros: Functions as an all-in-one glue, sealer, and finish. Water resistant, so perfect if you're mounting your kit on a foam board or framing without glass - makes it easy to dust. 

Cons: The big con is that some shine will be lost after sealing. Also, you won't be able to roll up your paintings after the sealer has been applied.

Our Recommendation: DecoArt's Triple Thick Glaze. In our experience, it has the perfect consistency, makes the canvas firm and sturdy, and retains as much sparkle as possible. For a slightly cheaper alternative, you can't go wrong with the classic Mod Podge

You Should Know: Using Mod Podge Glitter reduces the shininess of the diamonds and replaces it with the 'micro-fine' glitter in the sealer. Some people might not like the look, so be careful when choosing finishes. 

How To Seal Your Finished Diamond Painting

As a safety precaution, put pets and children in a separate room while you apply the sealer. 

Step 1: Make sure all diamonds are properly set by applying weight or using a rolling pin. 

Use the same technique you used initially to flatten out your canvas when you first got it. The goal is to make sure all diamonds are completely flat and locked tight to the canvas adhesive.

Pro Tip: Place an old tee shirt on the canvas to avoid scratching or breaking any diamonds.

Step 2: Dip the tip of your craft brush into your jar of brush-on sealer.

You can use just about any type of brush - foam or bristled. Our official recommendation is the Mod Podge Paint Brush Applicator (pictured) - it's just the right size to give you lots of control over where you apply the sealer. 


Step 3: Begin to apply the sealer to your canvas in broad strokes. 

The sealer will go on a thick white at first and look a bit like glue, but will become more transparent as it dries. Apply a thick, but full coating - no need to see globs of the stuff spilling over!  

The glue will make its way it between each and every diamond, hardening over the next day. 

What About Spray Sealers?

Aerosol spray sealers are used to coat the finished Diamond Painting in a crystal-clear finish. They do not function as a glue, so they don't fill the gaps in between your diamonds (like tile grouting!). 

  • Pros: Helps retain your diamond sparkle over time. It's waterproof, non-yellowing, and dries very quickly. Also, you're still able to roll up your finished canvas. 
  • Cons: Doesn't help cement drills to the canvas; any gaps between drills will remain unfilled.

Our Recommendation: We personally use Mod Podge® to seal all of our glass-framed Diamond Paintings. It's super easy to apply (just spray it on), non-toxic, and comes in different finishes and formulas. 

  • Mod Podge Super Gloss: We recommend the Super Gloss variety to preserve the shininess of your Diamond Painting.  
  • Mod Podge Matte GlossOnly use matte sealer spray if you want your Diamond Painting to be LESS shiny! 
  • Mod Podge Pearlized Gloss: This flavor will give your painting an extra pearly sheen to it. It's meant to add an extra little sparkle. 

Frequently Asked Questions 

Q: Can I use sealers with Partial Drill Kits? 

A: Yes, but go with a smaller brush! As much as possible, you want to avoid getting sealant on the parts of the canvas that have no diamonds. 

Q: Can I use sealers with Round Drill Kits?

Yes - sealing Round Drill kits works just as well as Square Drill.

    I used super gloss mod podge..good but lost some of the shine? Hadn’t seen about watering it down 50/50 so will try that next. Tried a aerosol clear sealer…NOT a good move..it melted all the adhesive base an the diamonds all lifted off…so DON’T try that? 😜

    I tried using the Mod Podge on a few of mine and I didn’t like how it turned out. I went on Amazon and found Cludoo Diamond Art sealer and it makes my paintings shine and it is not even messy…

    It sounds Like the mod podge shiny version is the best after reading all these comments. But I do think that people have missed the part where it says mix 50-50 with water. It seems like the people who mentioned using water had great results and the people who did not mention using water head dull results- just wanted to point that out

    I used high gloss mod podge on my DP and found it loosened the backing adhesive and caused movement on the canvas. Very annoying.

    I’ve found the aquamono glue from tombow to be the best sealer that doesn’t dull the sparkle at all. It’s water based so I put some on and spread it on with a small craft paintbrush in water to get an even coat and let dry which is super fast. And you’d never even know it was sealed.

    I have used the DecoArt Triple Thick sealer along with ModPodge brush for a very long time, in fact it is the only one I will use. It seals very well and you don’t lose hardly any shine if any at all.

  • Keith Perry said:

    Have done several diamond paintings. Modge Podge gloss mixed 50/50 with water is the way to go… Brush it on liberally and evenly and let it dry nicely and all original sparkle is retained. Modge podge glitter can be used for areas you want extra glitter but for most it will be overkill for an entire painting. I am in the process of even trying a couple paintings with glow in the dark glitter mixed in? I think it will be brilliant?

    In response to: [LInda said:(OCTOBER 06, 2019): When I pulled the cover off part of my canvas, it pulled some of the sticky off the canvas and I was not able to replace it. What can I use to get the drills to stick to the canvas?] And others with this issue!
    There are various brands of Spray Mount Repositionable Adhesives and Repositionable Tacky Sprays that can be bought at Michales and Hobby Lobby. I have not personally had to use any of these yet, so can not make any recommendations. Maybe someone else has used them and can reply with further suggestions.

    I use Modge Podge super brilliant gloss to seal my diamond paintings. For smaller ones I lay them flat in a drawer to prevent any dust or cat hair from getting on the wet canvas. For the bigger canvases I use a clothes hanger with clips on them. I clip the canvas to the clothes hanger and clip a few clothes pins on the bottom to keep it straight and weighed down. Make sure you hang your painting somewhere it won’t get bumped into or attacked by your furry friends. I hang mine on my shower rod in the bathroom and turn on the ceiling fan. I’ve done this with a 75×50 canvas and it worked well. If you have air bubbles in your sealant I use a hairdryer on a low heat setting to get rid of them. When your canvas is hardened and dry I then put my canvases in an assis artist portfolio to complete the curing process. I haven’t had a problem yet. Hope this helps!

  • Lillian Anderson said:

    I have done dozens of these. I have framed the really expensive ones professionally and have never sealed them. The ones that I do not frame, I have in plastic sleeves that I purchased at Hobby Lobby. Never had an issue with them falling off or anything. I keep them in a portfolio if I do not hang them in a frame. I would be careful sealing anything. I also do sculptures and different sprays make the colors and textures change sometimes and not for the better.

    To all those complaining about these guys not answering some of these questions,
    The article said, and i quote “Have any helpful tips about sealing your diamond painting? leave them in the comments below”
    as much as i’m sure that they would love to freely give their time to try to respond to every question, it is not practical especially if they have full time jobs and family responsibilities, with a little research you can find the answers you need online 😊

    When I’m done working for the day on my DP, to keep it flat, I hang it with a store’s hanger that has the clip ends they use for slacks and skirts. this way you can clip the ends of the painting on both ends of the canvas and let it hang straight. This has been working well for me. I use E6000 to seal my work; which has been working well so far.

    I’ve sealed many of my diamond paintings with mod podge super gloss. I water it down 50/50 and just brush it over the top quite liberally. I then just wipe over with a damp cloth to take it off the top of the drills. It doesn’t loose much shine at all and is still pliable enough to roll up bead side out of course 😉

  • Debbie Duckworth said:

    Place Foam Board under your DA while working it. When finished, place another FB on top. Turn the DA over. Gently slide out the bottom FB and then the top board. Roll over with heavy rolling pin in only one direction. After the popping sound is finished, press the backside of the canvas with a warm iron to soften the adhesive so the beads imbed well.
    Cool then turn back over and seal with the sealer of your choice.

    Used the high gloss Mod Podge to seal and was extremely disappointed in the outcome! All the dimensional sparkle was almost gone 😕. Not happy with the look at all. Gives it a one dimensional look. Any suggestions?

    I have tried mod page and found it made the drills dull. I have heard the aqua one is good so will try that and will also try the craft one you have talked about. I suppose it’s personal taste, but this has been really helpful. Thank you

    FYI decoart triple thick glaze and mod podge super gloss glaze are both out of stock EVERYWHERE, idk if they are being discontinued or everyone is using time at home during covid to do and seal paintings, and factories are shut down and can’t resupply stock. I found the last bottle of mod podge super gloss at Michael’s. Literally the last one in warehouse stock. Would be nice if you gave us more suggestions for brush on products.

    Diamond Glaze works and will even restore shine to areas where you have tried other sealers. I usually order from Amazon or Walmart.com. I cannot find it at any stores. I buy the refill size now.

    I love one commenter’s idea about Hobby Lobby’s heat service to melt out the wax and suck in the diamonds to the adhesive. After putting under glass (unless there is a distance between it and the background) I don’t feel the need to seal it.
