Over the past few months, you have spent nearly all of your free waking hours and possibly even time meant for sleeping placing thousands of tiny diamonds onto a sticky canvas one by one.
Now you take a step back and admire a beautiful diamond painting created entirely by your own hands.
It sparkles. It shines. It finally feels complete.
But if you want your diamond painting to look just as stunning years from now as it does today, sealing it properly is essential.
Why You Should Seal a Finished Diamond Painting
Sealing a diamond painting keeps every diamond securely in place and greatly extends the life of your artwork.
If you plan to hang your painting, display it without glass, or use magnetic or wooden frame strips, sealing becomes even more important. Without protection, diamonds may loosen, collect dust, or fall off over time.
Brush On Sealers
Brush on sealers are one of the most effective ways to protect a finished diamond painting. They are available in glossy, satin, and matte finishes so you can choose the final look you prefer.
Advantages
- They act as a glue, sealer, and finishing coat in one step.
- They are waterproof once dry.
- They are ideal for paintings displayed without glass.
- They make cleaning and dusting much easier.
Disadvantages
- Some formulas may slightly reduce sparkle.
- Once sealed, the canvas can no longer be rolled.
Recommended Products
- Aleeneās Original Acrylic Sealer Gloss provides a strong protective layer while drying clear.
- Liquitex Professional Gloss Medium creates a flexible and durable finish that helps maintain shine.
- FolkArt Acrylic Sealer Gloss is a budget friendly option suitable for large canvases.
Use caution with sealers that contain glitter or texture additives, as they can change the appearance of the diamonds.
How to Seal a Diamond Painting Using a Brush On Sealer
For safety reasons, keep pets and children out of the room while applying the sealer.
Step One Secure the Diamonds
Before sealing, make sure all diamonds are firmly pressed into the adhesive. You can place heavy books on the canvas for several hours or gently roll over the surface with a rolling pin.
To prevent scratching or damage, place a clean cotton cloth or an old T shirt over the painting while pressing.
Step Two Prepare the Brush
Dip the tip of a clean craft brush into the sealer. Both foam brushes and soft bristle brushes work well. Choose a size that allows you to control where the sealer is applied.
Step Three Apply the Sealer
Use long and even strokes to spread the sealer across the entire canvas.
The sealer may appear white at first, but it will dry clear. Apply a generous yet smooth layer. There is no need to flood the surface.
The liquid will flow between the diamonds and harden within twelve to twenty four hours.
Spray Sealers
Spray sealers create a clear protective layer on top of the diamonds, but they do not act as glue. They do not fill gaps between drills or reinforce loose diamonds.
Advantages
- They help preserve sparkle.
- They dry very quickly.
- They are waterproof and resistant to yellowing.
- The canvas can still be rolled after drying.
Disadvantages
- They do not secure loose diamonds.
- Gaps between drills remain visible.
