A Guide to Encasing Flowers in Resin

Not all of us live in an environment in which our favorite flowers to grow year-round. Whether you're a gardener or are perhaps looking for a way to preserve those flowers for safekeeping or to brighten up your décor, you could consider preserving flowers in resin.

Both dried and live flowers can be encapsulated in resin. However, live flowers fade in color, and bubbles may form as a result of the plant’s natural moisture. Therefore, for the best results, we recommend drying your flowers before encasing them in resin.

Process of Drying Flowers for Encapsulation

There are numerous methods of drying flowers. A relatively quick and easy way is to use flower-drying silica gel. If you like, take a look at this video or view a summary of the process below.

To begin, gather the flowers that you would like to dry. You can use live flowers from your garden or purchase some from a florist.

Pour your silica gel into a container that will hold the flowers you want to dry. Be sure you can cover the container!

Seal the container and set it aside for 2 to 3 days. Based on the silica gel used, most flowers will dry in a 2- to 5-day time frame.

The Process of Encapsulating Dried Flowers

Flowers can be encapsulated in resin for many types of projects. For now, we will focus on showing you a step-by-step guide through a specific example. In this video, you can see the process of embedding a dried flower in resin with a bottle-shaped mold. The result is then turned into an epoxy resin lamp.

What You Will Need:

  • ProMarine Supplies' ProPour Casting Resin
  • Dried flowers of your choice
  • A measuring cup or container in which to mix the resin in
  • Popsicle sticks for stirring and suspending the flowers
  • Glue
  • A mold of your choice (we use a bottle-shaped one!)
  • Gloves and Safety googles

For this project, we use our ProPour Casting Resin, which is perfect for object encapsulation. This product has a 2:1 by volume mix ratio that results in thicker pours and longer working times.

Before you begin this process, it is crucial to look over the instructions for ProPour Casting Resin. We also recommend pouring no more than 2" per application for smaller projects. Our flower encapsulation was done in one pour, but it may be easier to pour multiple thinner layers over time.

Make sure that your two-part casting resin is thoroughly mixed before preparing your dried flowers to be encased.

It helps to have an anchor supporting the flower such that it sits the way you’d like it to in the resin mold. Here, we firmly glued the flower's stem to a popsicle stick. Apply pressure until the stem is secured to the stick and the glue is dry.

Rest the stick against the bottom of the mold, as shown below, so that the flower will appear to be growing out of the bottom of the resin bottle. You can also dip your flower in a layer of resin before hanging it up and pouring into the mold. There are a lot of ways creators are discovering how to best preserve objects like flowers for their projects!

Hold the stick and flower in the spot you'd like it to stay while pouring ProPour Casting Resin into the mold. You should stop pouring just below the edge of the stick to retain the unique shape of the mold. It helps to have enough of the stem sticking out so that you can break the stick free after the resin has cured.

If you're looking to prevent bubbles, you can always use a pressure pot. Typically, you will want to put your project in the pressure pot before the open time of the resin is done and leave it in there until the curing time is up. Pressure pots apply pressure to minimize bubbles, and keeping your project in them for the entire curing time will avoid allowing air to expand those bubbles again.

Whether or not you use a pressure pot or not, be sure to allow the resin to cure for the appropriate time, as shown in the instructions.

Remove the stick from the stem. Try to break it such that only a small portion of the stem sticks out from the bottom as possible.

Snapping the stick free from the resin once it's cured to leave the flower in resin.

Gently loosen the mold from the bottom edges of the resin bottle.

Use it as a decoration, or turn it into a customized lamp, as we did. You can even use these methods during different seasons, such as for encasing autumn foliage and leaves.

Please be aware that we do not recommend using ProPour Casting Resin for outdoor applications.

Flowers in Resin Applications

A number of projects involve casting flowers in resin, including making bookmarks, jewelry, and paperweights, as well as encasing wedding flowers in resin. Encase flowers to make them last, preserve a cherished memory, or to create decor inspired by Mother Nature.
