From little moments to lasting sparkle — that’s DYC.
I used to seal every painting. Then I stopped sealing for a while. Now I only seal the ones that travel, hang without glass, or get touched a lot. Here’s the gentle truth, from someone who tried all the messy ways first.

Q1: Do I really need to seal?
Honestly? No — not always. If you put your diamond art behind glass, the frame does the job. If the painting stays flat, clean, and calm, sealing won’t add anything meaningful.
But… if it travels, gets handled, or hangs open on the wall, sealing gives peace of mind.
Q2: When should I NOT seal?
- When framing behind glass.
- When you want the full sparkle — nothing beats unsealed shine.
- When the glue surface is perfectly clean and flat — just enjoy it.
Real experience: My brightest pieces are unsealed and framed — people always notice the sparkle first.
Q3: Brush-on or spray?
Brush-on: stronger protection, best for square drills, helps stop popping.
Spray: softer and keeps more sparkle, great for round drills.
Veteran truth: thin coats beat thick coats every time. Thick coats pool in the gaps and look muddy.
Q4: Will sealing make my diamonds dull?
A tiny bit, yes. Sealing fills the air spaces that make diamonds glitter. But sealed paintings still sparkle — just softer.
My rule: sentimental pieces (pets, weddings, memorial gifts) — I seal. Art pieces meant to shine like stars — I don’t.
Q5: How do I avoid cloudy or milky spots?
- Thin layers, always.
- Let each layer dry fully.
- Low humidity — sealing hates wet air.
- Never shake a spray sealant — that makes bubbles and haze.
Learned the hard way: I sealed on a rainy day. It dried cloudy, and I had to redo it. Dry room = happy seal.
Q6: Square vs round — does sealing work differently?
- Square drills lock together nicely — brush-on fills tiny gaps.
- Round drills have more space — sprays look more natural.
Q7: Can I seal partial drills?
Yes, just seal the diamond area only. The printed canvas doesn’t like sealant — it can leave shiny rings or waves.
Q8: What if drills are popping up?
- Roll the canvas gently.
- Warm the back for a few seconds, then roll again.
- Press each loose drill before sealing.
Important: sealing does not push popped drills down — you have to place them back first.
Q9: How long should it dry?
- Spray: 2–4 hours.
- Brush-on: overnight.
- If framing after sealing — at least 24 hours.
Personal rule: if I can smell sealant, I don’t frame it yet.
Tiny veteran secrets (just between crafters)
- Seal in daylight — artificial light hides puddles.
- Cover the table — wet sealant attracts dust like a magnet.
- If sealing outside, bring the piece inside to dry. Nothing loves wet sealant more than tiny insects.
- For huge pieces, seal in small sections. Calm hands look better than rushed arms.
- Always test a tiny bottom corner first — no stress, no regrets.
Sealing shouldn’t feel stressful. It’s just a soft final step — like tucking a blanket around something you care about.
Quick summary
- Behind glass? You probably don’t need sealing.
- Want protection? Brush-on is strong, spray is gentle.
- Thin coats, dry fully, low humidity — the magic trio.
- And always test a small corner first.
Some paintings shine brighter without sealant. Some feel safer with it. Either choice is right — as long as it makes you happy.
