For a canvas that's lost its stick, the Diamond Dotz Dotz Stick is the glue to buy: a clear, water-based gel made for diamond painting, with 4.7 stars from more than 1,200 ratings and about 1,000 sold last month. But check what you're actually fixing first. Drills falling off a finished piece, drills going onto a wooden ornament, and a painting that needs protecting each call for a different glue, and the wrong one either won't hold or will dull the sparkle.

How we picked these glues
We searched Amazon for diamond painting glue and adhesive on October 13, 2026, then sorted the results by job. Dry times, sizes and formulas come from each listing. We favored products with big rating counts, but the two purpose-made canvas repair glues are newer and have few ratings, and we've flagged that where it applies.
This is a "How we pick" guide. We haven't tested these glues side by side; the picks rest on listings plus Amazon's sales and rating data. How we research.
Four different things called "diamond painting glue"
| Product type | What it does | When drills go on | Example |
|---|---|---|---|
| Canvas glue (re-tack) | Restores a sticky layer on dead or bald patches | After it turns clear and tacky | Dotz Stick, Picmondoo |
| Drill glue | Fixes one drill, or drills on wood, glass or plastic | Into the wet dot | Tombow Mono Aqua, Aleene's Liquid Fusion |
| Sealer ("glue sealer") | Locks finished drills down, adds shine | Never; it goes on top | Topwey, Mod Podge Diamond Top Coat |
| "Glue clay" | Pen wax for picking drills up | Not a glue at all | See wax vs putty |
Which glue for which problem
Before you buy anything for a patch that won't hold, read our guide to drills not sticking. Wax rubbed off the pen and dust are the usual culprits, and both clean off. And if the kit is from a brand with an adhesive warranty, such as Diamond Art Club, contact them before adding glue.
Best glue for a dried-out canvas
Diamond Dotz Dotz Stick
The most-bought glue made for diamond painting, from the Diamond Dotz brand. It's a gel, which is easier to keep on just the dead cells than a runny liquid, and it dries transparent. The listing pitches it for fixing loose drills and for covering larger areas. About 1,000 bought last month, 4.7 stars from 1,214 ratings.
- Typeclear water-based gel
- Size4 fl oz (118 ml)
- Full cure1.5 hours (listing spec)
- Also forloose drills, puzzles
Why it stands out
- Largest rating base of the purpose-made glues
- Gel stays where you put it
Think twice if
- No applicator brush in the box
- The listing's spec table oddly includes "Toxic" among its features; treat it as an adult supply
Picmondoo Diamond Painting Canvas Glue
Made for one job: renewing tack on canvas that's lost it. It goes on milky white, so you can see exactly where you've brushed, and turns clear as it dries. The small silicone brush is the right tool for working cell by cell. The catch is evidence: 4.8 stars from only 9 ratings.
- Size4.06 fl oz (120 ml)
- Includesmini silicone brush
- Dry timeabout 30 to 45 minutes to turn clear (listing)
- Appearancemilky white when wet
Why it stands out
- Brush included
- Visible while wet, so no missed spots
Think twice if
- Very few ratings
BQDQYBS Clear Tacky Canvas Repair Glue
Another purpose-made repair glue, and the listing is clear that it's "not a diamond art sealer". It says the patch is ready for drills within 30 minutes, and it also suits painting on blank, unglued canvas. 4.6 stars from 20 ratings.
- Typeclear tacky adhesive
- Ready for drillswithin 30 minutes (listing)
- Also forblank canvas freestyle
Why it stands out
- Quick turnaround
- Works for freestyle on blank canvas
Think twice if
- Small rating base
How to re-tack a patch
- Clean the patch. Dab it with a lint roller or tape to lift dust; scrape off pen wax with a fingernail or a plastic card.
- Test the glue on the unpainted border so you know its tack time.
- Brush on the thinnest layer you can, on the dead cells only. Thick glue lets drills slide and leaves a haze.
- Wait until it's clear and tacky, not wet.
- Place drills, then press them down with a roller.
- Cover anything you aren't working on with release paper.
Best glue for loose drills and other surfaces
Tombow MONO Aqua Liquid Glue
When three drills pop off a finished painting, you want a pinpoint of glue, not a brushful. The fine pen tip puts a dot in one cell, and it dries clear. It's a school-and-office staple with 4.7 stars from 3,732 ratings and about 2,000 bought last month.
- Size1.69 oz
- Tipsfine pen tip and broad tip
- Bondpermanent, dries clear
- Formulawater-based, acid-free
Why it stands out
- Fine tip for single cells
- Washable, odorless
Think twice if
- Dries hard, so place the drill while it's wet
Aleene's Liquid Fusion
For putting drills on things that never had adhesive: wooden ornaments, glass, picture frames, freestyle projects. It dries clear and the listing says it's waterproof, which matters for anything that gets handled or wiped. A huge track record, too: 4.7 stars from 11,388 ratings, about 2,000 bought last month. Our diamond painting ornaments guide has projects to use it on.
- Size4 fl oz
- Typeurethane, clear
- Featureswaterproof, non-foaming, low odor (listing)
Why it stands out
- Waterproof
- Bonds non-porous surfaces
Think twice if
- Best on non-oily surfaces, per the listing
FITTDYHE B7000 Glue Kit
B7000 is the glue rhinestone and nail-art crafters use, and this kit adds a dotting pen for picking up stones. It stays slightly flexible, so it suits drills on fabric, phone cases or shoes. About 8,000 bought last month, 4.6 stars from 2,739 ratings. The title says 50 ml while the bullets describe a 110 ml bottle, so check the size you're sent.
- Size110 ml (kit listing)
- Tipneedle precision cap
- Extrasglue spreaders, 2-way dotting pen
- Typeflexible clear gel
Why it stands out
- Needle tip, flexible bond
- Dotting tool included
Think twice if
- Size inconsistent in the listing
- Overkill for canvas repairs
When you need sealer, not glue
A finished piece with no bare spots doesn't need glue; it needs sealer if it'll be handled. The Topwey Diamond Painting Glue is sold under both names: it's a water-based coat brushed over finished drills, which the listing says needs at least 2 hours to cure. Our sealer guide compares it with Mod Podge Diamond Top Coat and sprays, and explains how to avoid dulling the sparkle.
Home fixes: what works and what doesn't
| Fix | Verdict | Why |
|---|---|---|
| Light water mist | Risky | Some canvas adhesives soften in water; too much ruins the patch. Test on the border. |
| Glue stick | Stopgap | Dries rather than staying tacky; can leave a dull film |
| Clear nail polish on the drill back | OK for one drill | Works like drill glue; slow for more than a few |
| Double-sided tape | OK for a bald strip | Cut to the cells; edges can show between round drills |
| Heat (hair dryer) | Check the brand first | Some brands ask you not to; it can soften drills and canvas |

Keep the glue from dying in the first place
Most dead patches are preventable. Keep the canvas covered when you're not working, keep pen wax light so it doesn't rub onto the glue, store the canvas flat in a cool room away from sun, and wash your hands before resting them on open glue. If you're short drills rather than stickiness, see our missing drills guide.
