If you are into art, then you already know that DecoArt is a renowned paint brand. But did you know that they make other art supplies of great quality? This thick glaze can be a testament to that.

This product applies on all sorts of surfaces– from wood to china to metal, and it provides the smoothest finish you’ll come to love. Since it is so thick, one coat is all you need for the perfect finish.

A staple item for DIY crafters all around the world, Mod Podge is an all-in-one product that can be used as a sealer, adhesive glue, finishing, and more!

This particular version is different from the classic, as it comes with glitter inside. So, your diamond art will get a unique sheen. Also, clean-up is easy; it just needs water & soap. And it dries quickly!

Next, we have another Mod Podge product, and this one is a spray sealant.

The formula of the product is clear. It comes off clear, dries clear, and stays that way. So, say goodbyes to dull sealants that turn yellow over time.

We loved how quick drying it is. It’s very easy to apply, dries quickly, and can be cleaned up just as easily. Also, it doesn’t run. What more could you ask for?

5. Unicorn Art Epoxy Resin Kit Clear Casting Liquid

Epoxy resin is a fan favorite when it comes to any form of craft– from woodworking to painting to sculpting. If you want to try this wonder fluid on your diamond art, no other brand makes one as good as Unicorn Art.

A common worry about epoxy resins is that they are toxic. This one is not toxic, and there are no fumes or odors in it. Also, it levels by itself and cures in a varnish-like finish.

Did you think we were done recommending Mod Podge? Well, you are wrong! This next one is an ultra-glossy formula that comes in a small, convenient size. And if you prefer a matte instead, that is available too.

Because of the high adhesion, rest assured that your tiny diamond pieces are well-protected. I also appreciate that it can be used both indoors and outdoors, which means the sun will not change its color. Despite being high-adhesion, it dries completely non-tacky.

Pros

8. Picmondoo Diamond Painting Conserver

Up until now, we have not talked about any product specifically made for sealing diamond paintings. Picomondoo is a brand dedicated to making diamond art-related products only, so you can guess that this must work amazingly well.

It will drill diamond paintings and seal all the rhinestones in place for good. Furthermore, it will work well with 5D diamond paintings, too, aside from the more common 3D ones.

Generally, the shine of the rhinestones is unaffected, but one user did complain otherwise. So, we would recommend doing a test drive before using this, just to be safe.

Last but certainly not least, we have another dedicated diamond sealer from Judikins. As it is made exclusively for diamond painting sealing, it marvels at the task effortlessly.

The application technique of this product is unique; you just have to pour directly from the bottle. No mixing, shaking, spraying, or rushing is required. It does not get easier than this.

How to Seal Diamond Painting Easily

Before we get to the product description and reviews, let’s first see how you actually seal a diamond painting. Simply follow the steps below–

Step 1: Applying Weights

First, you have to ensure that all of your little diamond beads are properly and fully stuck to the canvas. To do that, you need either a rolling pin or some sort of weight. With the rolling pin, press and roll firmly all over the canvas to ensure that the diamonds are stuck.

Then, with any weights, place them on top of the canvas for a few minutes, ensuring that all diamonds are covered.

Doing this will ensure that all of the little diamonds are totally flat against the surface and are locked in tight to the adhesive.

Tip: Cover the canvas with an old t-shirt to prevent any breakage or scratches on the diamonds.

Step 2: Dipping the Brush (Subjective)

This is only applicable if you are using a sealant in a jar. Otherwise, go to step 3.

Use any type of brush you have at hand– bristled or foam– and dip its tip inside the jar. Be careful not to take too much product in one go. Then, begin applying it. The product will look thick & white initially, similar to glues, but do not fret; it will turn clear as it dries down.

You can apply thick coatings, but ensure that they are full coatings. Otherwise, the surface will look uneven.

The thick product will fill all the tiny gaps in between every diamond. It will take about a day to dry and harden properly. Other advantages include waterproofing, dirt resistance, ease of cleaning, durability, etc. The biggest con is that the painting will not be rollable anymore.

Step 3: Using a Sprayer (Subjective)

If you are using a spray sealer, avoid step 2. The advantage of spray sealers is that they coat the diamonds in a crystal-clear shiny finish, so your diamonds will not lose their sparkle as time passes. Also, your painting can be rolled up if needed. And these sealers dry much quicker.

But the downside is that spray sealers will not fill in any gaps that are present in your canvas, which the dipping ones will. So, the beads will be less secured comparatively

To apply, simply spray a nice even layer of the sealant on your painting, avoiding the surrounding areas as much as possible. Also, use tape around the edges of the painting for a clean finish. And you are good to go!

Diamond Painting Sealer Buying Guide

Before you get diamond painting sealers, you should consider a few factors to ensure that you have the perfect match. They are explained below–

Finish

If you want a crystal clear and highly shiny finish, then a spray sealer would be great for you. For a thick, varnish, or glass-like finish, avoid sprays because they will not work. Get a jarred version or epoxy resin.

Some may even prefer a matte finish, which can be found in some Mod Podge products.

Mix-ins

Generally, all sealants are clear or get clear after they dry down. However, some of them come with fun mix-ins such as glitter. Glitters can add a bit of dazzle to your diamond art. However, if you do not properly check the labels and accidentally buy one, it will be an unwelcome surprise.

So, make sure the product you are buying is actually what you think it is– otherwise, you would have wasted your money.

Requirement

Think about the pros and cons of spray and jarred sealants and match them with what you want. If you want to be able to roll up your art to transport or stash it somewhere, then you must stick to sprays. Again, if you want a sealant that will dry fast, sprays are your best bet.

On the other hand, if you want your sealant to fill the drill and all the little empty spots in between the rhinestones, then you must use a jarred sealant. Sprays cannot provide that.

Also, if you want a varnish or glass-like hard, smooth surface, jarred ones are more appropriate for you.

Ease of Application

How much effort you are willing to put in also matters. Some sealants like epoxy resin require measurement and mixing, which may be a hassle. The jarred ones do not provide enough control, as you have to use a brush to apply. Also, they may leave brush strokes sometimes.

In terms of ease of application, the sealants meant for directly pouring, or the ones that use a spray mechanism are the easiest to use. However, they do have some serious drawbacks, which you should keep in mind.

Also, keep ease of clean-up in mind. Spending hours cleaning up after an accidental spill is dreadful and should be avoided.

Drying Time

Are you in a hurry to gift your prized possession to someone and have decided to quickly apply a coat of sealant before giving it away? Well, if that is the case, then getting a jarred sealant would be counterproductive since they need at least one whole day to dry.

So, depending on your emergency, choose the item.

Price

Every purchase decision should have a fixed budget. You do not want something so cheap that it fills your room with toxic fumes and leaves bubbles & glops everywhere. But you also do not want a sealer that costs almost as much as the diamond painting kit itself.

So, set a reasonable budget range and shop accordingly.

Safety

Check if the sealant contains harmful ingredients or toxic fumes. Stay away from it if it does. You should always keep safety at the 1st on your priority list.

Generally, water-based products are the safest to use. But this does not mean that acrylic ones are bad. They can be toxic, though, so you must always verify before adding the product to your cart.

Frequently Asked Questions (FAQs)

1. Can I use sealers on partially done diamond art?

Answer: Sure, you can. But, be careful not to get any sealers on the blank canvas when doing so. You should apply on to the partially done diamond beaded areas. To ensure that, you can use smaller brushes and something to cover up the blank part if spraying.

2. Do diamond art kits come with sealers?

Answer: Usually, diamond art kits do not come with any sealants. You have to buy them on your own. The regular items included in a kit are– canvas with an adhesive layer, acrylic rhinestones, applicator tool, tweezers, and adhesive wax.

3. How does diamond painting come together?

Answer: It is fairly simple! First, remove the protective layer on top of the pre-painted canvas. Then, follow the specific colors and guide to apply the diamonds to the painting carefully. It will make sense once you finish!

4. Can I use the adhesive wax for sealing?

Answer: No, you can’t. The provided wax is meant for helping you pick up the tiny pieces of rhinestones. They are not suitable for sealing. Using it can even ruin your work.

5. What is partial diamond art?

Answer: This refers to a canvas that is not meant to be totally covered by diamonds. For this type of canvases, you only need to cover a specific part of the canvas. This is perfect for novices who might not have the patience to sit and finish an entire diamond art kit.

Final Words

Diamond painting takes a lot of time. With the perfect sealer, the art that you have spent so many hours on can be protected and proudly displayed. It will also enhance the overall look of the painting. And, with a sealer, the diamond art will last for a really long time, without missing pieces or losing shine.

So, skipping the sealer is not recommended. If you follow our article, you can easily get the best sealer for diamond painting at your disposal.

Hope you have a relaxing session! Don’t rush the process!
