You’ve spent hours placing each tiny gem with care—your diamond painting looks stunning. Now comes the big question: do you need to seal it? The answer isn’t one-size-fits-all. While sealing offers protection, it’s not always necessary, especially when using high-quality diamond painting kits with full tools like those from FEELOOK Art. This guide will help you decide when sealing is worth it and how to do it right.

When Should You Seal Your Diamond Painting?

Sealing is optional—but in certain situations, it’s highly recommended:

• If drills are loose or pop off easily
  Some low-quality canvases may have weaker adhesive. Sealing can lock everything in place.

• If you’re not framing the painting behind glass
  Open display leaves your artwork exposed to dust and moisture. A sealer adds a protective layer.

• If you want long-term storage without a frame
  Sealing helps prevent diamond shifting during handling or moving.

But if you’re working with a premium full drill diamond painting and framing it properly, sealing may not be necessary.

Pros and Cons of Sealing

To maintain the brilliance of your round drill diamond painting, it's crucial to use the right type of sealer.

What Happens If You Don’t Seal It?

If you skip sealing, your diamond painting can still last for years—especially if you use quality kits and frame the piece. For example, our Ocean Girl design features 28,747 round drills on a sturdy adhesive canvas, making sealing optional if framed properly.

Another option like Fish School with over 31,000 drills also offers strong hold—but if displayed without a frame, a light seal might be a good idea.

Types of Sealers for Diamond Painting

• Brush-on Sealers
  Offer full control and thick coverage; ideal for heavy-use pieces.

• Spray Sealers
  Easier to apply, preserve shine better, but may require multiple coats.

• Glue or Mod Podge
  Popular choice among crafters—just make sure to choose a glossy, non-yellowing formula.

🛑 Avoid using regular household glues or matte finishes that can cloud the gems.

Framing vs. Sealing: Which Is Better?

Framing behind glass or acrylic provides dust protection without sealing, preserving the full drill sparkle effect. Want inspiration? Browse our Ocean & Beach Collection for display-worthy pieces that don’t need sealing when framed.

If you’re gifting or shipping a painting without framing, sealing offers practical durability.

Final Thoughts: Seal When It Makes Sense

Whether you’re working on a custom piece or a beginner-friendly canvas, sealing your DIY diamond painting kit is a personal choice. If your artwork will be handled frequently or displayed openly, sealing can offer peace of mind. If you’ve chosen a high-quality kit and plan to frame it, your masterpiece is already built to last.
