How to Frame & Display
Your Diamond Painting

You've placed every last drill. Now let's put it on the wall where it belongs. This guide covers everything from flattening a curled canvas to sealing the drills, picking the right frame, and hanging it straight — in plain steps, no jargon.


What you'll need

Most of these are inexpensive and easy to find at any craft store or online.

Six steps to a framed finish

1

Flatten the canvas

Most canvases arrive rolled and stay curled even after you finish the artwork. Lay it face-down on a clean flat surface. Place a damp cloth on the back, then stack heavy books on top. Leave it for 12–48 hours.

For a quicker fix, hold a hair dryer on its lowest setting about 20 cm from the back of the canvas. The warmth relaxes the fibres without damaging the drills. Never use a hot iron directly — it melts the resin.

2

Seal the drills

Sealing locks every drill permanently to the canvas so nothing falls out when the piece is moved, handled, or hung on a wall. Apply 2 to 3 thin coats — not one thick one.

  • Brush-on: Pour a small amount onto a palette. Use a foam brush in light, even strokes across the whole surface.
  • Spray: Hold 30 cm away. Use sweeping passes, two or three light layers. Do this in a ventilated area.
⚠️

One thick coat clouds the drills and kills the sparkle. Always go thin.

3

Let it dry fully

Wait at least 2–4 hours between coats and a full 24 hours before framing. Rest the canvas flat with the sealed side facing up. Keep it in a clean, dust-free spot, away from direct sunlight while it cures.

4

Choose your frame

Pick the framing style that suits your space. One rule applies to all of them: never place glass in front of the drills. Glass flattens them and kills the sparkle completely.

  • Picture frame (glass removed): The easiest option. Buy a frame that matches the worked area of your canvas and remove the glass before inserting.
  • Stretcher bars: Wooden bars that the canvas is stretched over and stapled to at the back. No outer frame needed — clean gallery look.
  • Floating frame: Canvas sits inside with a small gap around it. Modern and minimal.
  • Shadow box: Adds depth. Works well for smaller pieces and gifts.
💡

Measure the worked area of the canvas — not the full sheet including blank borders — before buying a frame.

5

Mount the canvas

Picture frame: Trim any large blank border, leaving about 2 cm to fold behind. Place the canvas face-up in the frame. Fold the border over the backing board and secure with double-sided tape or framing clips. Re-attach the backing.

Stretcher bars: Assemble the bars, centre the canvas over them (drills facing up), and staple at the centre of each side first. Work outward alternating sides until the tension is even with no puckering. Fold the corners neatly before stapling.

6

Hang and display

Choose a spot with good lighting — warm white light makes diamond drills sparkle brilliantly. Avoid harsh direct sunlight, which fades the canvas over time.

  • Use a spirit level to mark the position straight
  • Adhesive strips (Command Strips) for pieces under 1 kg
  • Wall anchors and D-ring hooks for larger or heavier frames
  • Hang at eye-level — about 145–150 cm from floor to the centre of the piece

A small LED picture light mounted above the frame transforms the sparkle. It's the single biggest upgrade you can make to any diamond painting display.

Things to avoid

✕

Leaving the glass in the frame

Glass presses flat against the drills, crushing the 3D texture and wiping out all the sparkle. Always remove it.

✕

Applying sealer in one thick coat

A thick coat turns cloudy and yellows over time. Two or three thin coats give a clear, lasting result.

✕

Framing before the sealer has cured

Mounting too early traps moisture inside the frame. Wait the full 24 hours or drills may loosen.

✕

Measuring the full canvas instead of the worked area

The blank border adds size. Measure only the drilled area or your frame will be the wrong size.

✕

Using a hot iron to flatten the canvas

Direct heat melts resin drills instantly. Always use books and a damp cloth, or a hair dryer on the lowest setting.


Quick questions

Do I have to seal my diamond painting before framing?
You don't have to, but you really should. Sealing bonds every drill to the canvas so they can't fall out once the piece is on the wall. It also protects against dust and humidity. If you're displaying it long-term, seal it first.
Why can't I use glass in the frame?
Glass sits directly on top of the drills and flattens them — removing the 3D texture and all the sparkle. The sealer already protects the surface from dust, so glass adds nothing and only damages the look.
What frame size do I need?
Measure the drilled area of your canvas — not the full sheet. Common kit sizes and their frame matches: 30×40 cm = 12×16 in frame · 40×50 cm = 16×20 in frame · 50×70 cm = 20×28 in frame.
Can I stretch the canvas over wooden bars myself?
Yes. You need a stretcher bar set (sold in pairs), canvas pliers, and a staple gun. Staple at the centre of each side first, then work outward alternating sides for even tension. It takes about 20–30 minutes and gives a clean gallery-wrapped result.
How do I flatten a canvas that's still curling?
Lay it face-down, put a slightly damp cloth on the back, and stack heavy books on top. Leave for 12–48 hours. For a quicker result, use a hair dryer on the lowest heat setting held 20 cm from the back. Never touch the front with any heat source.
Brush-on or spray sealer — which is better?
Both work well. Brush-on gives you more control on large pieces — use a foam brush in thin even strokes. Spray is faster and smoother but needs good ventilation. Apply 2–3 light coats either way. Brands: Mod Podge or Aleene's for brush-on; Krylon for spray.
