How to Preserve a Wedding Bouquet in Resin

Your wedding bouquet carries one of the most emotional moments of your life — the walk down the aisle, the toss, the photographs. Pressed albums fade and dried bouquets crumble within a year. Resin, on the other hand, locks every petal in glass-like clarity that lasts decades.

Whether you want a paperweight on your desk, a coaster set for anniversaries, or a framed shadow box for the wall, resin lets you keep the actual flowers from your wedding — colour, shape and all — forever.

• Your fresh bouquet (start within 24–48 hours of the wedding)
• Silica gel — the fine, flower-drying grade
• An airtight container large enough to hold the blooms
• Two-part clear casting epoxy resin (look for low-yellowing, UV-stable)
• Silicone moulds in the shape you want (round, square, heart, photo frame)
• Digital scale, mixing cups, stir sticks
• Heat gun or small culinary torch
• Nitrile gloves and a respirator mask — resin fumes are not optional

Fresh flowers preserve best. The longer you wait, the more colour and structure you lose. If you can't start immediately, refrigerate the bouquet wrapped loosely in damp paper towel, but begin drying within two days at the latest.

Snip each stem about 1 cm below the bloom. Separate every flower and remove ribbons, pins, wires and any bruised petals. Drying works far more evenly on individual blooms than on a tightly bound bouquet.

Pour a 2 cm bed of silica gel into your airtight container. Place each flower face-up on the bed and gently spoon more silica around and over the petals until fully buried. Seal the container and leave it for 10–14 days in a cool, dry spot.

When done, the petals should feel papery and slightly stiff. Brush off the silica with a soft makeup brush. Skip this step at your peril — undried flowers go brown inside resin within weeks.

Lay out your dried blooms next to the mould and plan the composition before you mix anything. Popular options include:

• A round paperweight with one signature rose at the centre
• A square block with petals scattered like confetti
• A heart-shaped keepsake for the anniversary table
• A photo-frame insert combining your wedding photo and petals

Measure resin and hardener by weight on a digital scale at the exact ratio your brand specifies (commonly 1:1 or 2:1). Stir slowly for a full 3 minutes, scraping sides and bottom. Rushed mixing is the number-one cause of sticky, cloudy resin.

Pour a 5–10 mm base layer into the mould and let it set to a tacky gel (about 6–8 hours). Place a few flowers face-down on the gel, pour another thin layer over them, and repeat until the mould is full.

This layered approach stops flowers from floating to the surface, tilting, or trapping air bubbles under the petals.

After each pour, wait two minutes for bubbles to rise, then sweep a heat gun or torch lightly across the surface from about 15 cm away. Don't hover — too much heat scorches the resin yellow.

Leave the final pour to cure undisturbed for 48–72 hours at a warm room temperature (22–25°C is ideal). Demould carefully, sand any sharp edges with wet sandpaper (400 → 800 → 1500 grit), and polish with a resin polish for a glassy mirror finish.

• Skipping the silica drying step — fresh flowers rot inside resin.
• Pouring too thick in one go — thick pours overheat, yellow and crack.
• Wrong mix ratio — measure by weight, never by eye.
• Cold workspace — below 20°C, resin cures cloudy or sticky.
• Dust during cure — cover the mould loosely with a cardboard box.

Preserving an entire bouquet is a 2–4 week project with real risk of ruining irreplaceable flowers on the first attempt. At ResinKriti we preserve wedding bouquets, temple flowers and other floral keepsakes by hand — drying, casting, finishing and shipping a museum-quality piece you can pass down.
