How It Works
A diamond painting kit is a canvas printed with a grid of symbols and covered in a layer of glue under a protective film. Each symbol stands for a colour of tiny resin "drills". You dip a pen in wax so the tip is sticky, pick up a drill, and press it onto its symbol. Fill every symbol and the picture appears — glittering, like a mosaic.
In the box: the canvas, bags of drills labelled with colour codes, a drill pen, a block of wax and a ridged tray that turns the drills right side up when you shake it.
The Choices That Matter
| Choice | Options | What it means |
|---|---|---|
| Drill shape | Round (about 2.8 mm) or square (about 2.5 mm) | Round leaves small gaps and a soft sparkle; square fits edge to edge for a seamless mosaic |
| Coverage | Full or partial drill | Full covers the whole canvas; partial leaves some printed background bare — quicker for a first kit |
| Canvas size | 13 × 18 cm cards up to 40 × 50 cm and larger | Small canvases can't hold much detail but finish fast |
| Special drills | AB, fairy dust, electro, glow-in-the-dark | AB drills have a rainbow coating; others add glitter or a metallic look |
For a first kit: pick something small — a postcard or 30 × 30 cm canvas — and a clear design with large areas of one colour.
How Long It Takes
Roughly 6–10 hours for a small 20–30 cm canvas, and 20 hours or more for larger designs. Postcard kits like the Foreveryoung Minigem cards take about three hours each.
Tips for Your First Painting
- Peel back a little at a time. Uncover only the section you're working on and keep the rest under its film so the glue stays tacky.
- Re-wax often. When the pen stops picking drills up, press it into the wax again.
- Fight static. A dryer sheet wiped over the tray stops drills jumping around.
- Use a multi-placer for big areas of one colour; it picks up several drills at once.
- Don't iron a canvas once drills are on it.
Finishing and Displaying
- Press the drills down firmly with a roller or a book when you finish.
- Framing behind glass protects the picture without sealing.
- To seal, brush on one thin coat of a water-based sealer with the canvas flat, and leave 12–24 hours between coats. Avoid products that can yellow over time.

Frequently asked questions
Round or square drills — which is better for beginners?
Either works; it's preference. Round drills (about 2.8 mm) leave small gaps and give a soft sparkle, while square drills (about 2.5 mm) sit edge to edge for a seamless mosaic. Some guides find round easier to place, others say squares are easier to line up.
How long does a diamond painting take?
A small 20–30 cm canvas takes roughly 6–10 hours; larger designs take 20 hours or more. Postcard-size kits can be done in an evening.
Do you have to seal a diamond painting?
No. Framing it behind glass protects it without sealing. If you do seal it, press the drills down with a roller first and brush on one thin coat of a water-based sealer with the canvas lying flat.
What is a partial drill kit?
A partial drill kit only covers part of the canvas with drills; the rest is printed background. It's quicker and easier, which suits beginners and children. Full drill kits cover the whole canvas.
Do I need a light pad?
No, but a light pad under the canvas makes the symbols easier to read, especially on dark designs, and shows up drills in the wrong place.
