An Easy to Follow Guide of How to Preserve Flowers in Epoxy

Step 1: Trim and Dry the Wedding Bouquet

Before beginning, trim the stems of your bouquet and ensure your flowers are completely dry as moisture can cause them to rot and change color within the resin. Here are several methods for drying flowers, the method used will be dependent on what is available to you and the project you are doing:

  • Silica gel: Place fresh flowers in a sealed container with silica gel desiccant for several days or up to a couple of weeks. This is the preferred method for color and shape retention. Wisedry is an excellent option. Note that silica beads can cause indents on the pedals, we always recommend using silica crystals.

  • Air dry: Allow the flowers to dry naturally in a vase or box.

  • Parchment paper: Place flowers between folded parchment paper and press them between the pages of a heavy book.

  • Microwave: Dry flowers in 1½ to 3 minutes using a microwave flower press.

Step 2: Choose and Measure Your Floral Preservation Mold

Select a silicone or HDPE mold that best displays your flowers. Afterward, measure the mold and use our coverage calculator to determine the amount of Liquid Cast Floral Preservation Epoxy Resin required.

Step 3: Prep the Epoxy Resin Mold

Clean the mold with water or isopropyl alcohol and a paper towel to remove any dried epoxy resin or dust. Ensure it is clean and dry before use.

Step 4: Measure and Mix the Casting Resin

Combine one part of Liquid Cast Floral Preservation Epoxy Resin (A) with one part hardener (B), ensuring a thorough mix. This formula is perfect for thick pours and cures crystal-clear, making it ideal for flower preservation. Be sure to measure accurately and mix thoroughly. Scrape the sides and bottom of the container while mixing to prevent any unmixed epoxy resin in the final project.

Note - Some casting resins are not a 1:1 mixing ratio. Liquid Cast Floral Preservation Epoxy is beginner friendly and easy to use.

Step 5: Pour the First Layer of Casting Resin into the Mold

Pour the first layer of epoxy resin into the mold at ~¼” thick, carefully observing for bubbles. Use a heat gun to eliminate bubbles, checking the resin every 15 to 30 minutes until no more bubbles form. Use only quick passes over the top of the epoxy resin with the heat gun, do not overheat the epoxy resin or your mold.

Step 6: Allow the Epoxy Resin to Harden, Arrange Your Flowers, and Pour Another Layer

After ~24 hours the epoxy resin will have hardened enough to pour the next layer. At this point you can arrange your flowers in the mold and mix another batch of epoxy resin. Pour another layer in ~¼” layer using a heat gun to prevent bubbles.

Tip - To prevent bubbles under the pedals you can carefully dip them into epoxy resin or flood them with epoxy resin before placing them in the mold.

Step 7: Continue to Pour Additional Layers of Casting Resin

Around 24 hours after your epoxy resin was poured you should be okay to add an additional layer. Continue pouring in ¼” layers until you reach the desired depth.  

Step 8: Allow the Casting Resin to Cure

Give the Liquid Cast Floral Preservation Epoxy Resin at least three days to fully harden, sometimes longer depending on the size of the mold and amount of epoxy resin used.

Step 9: Demold the Floral Preservation Cast

Carefully remove the cured epoxy resin from the mold. If necessary, apply soapy water to the silicone mold to facilitate removal.

Step 10: Apply a Doming Layer of Epoxy Resin (Optional)

If you have any sharp edges you can remove them carefully with a utility knife. An optional step is to apply a doming layer on top of the finished cast which will give it a professional looking finish. Apply a layer of our Liquid Art Ultra UV Resin and slowly move it to the edge without allowing it to run over. This will give you an additional layer of clear UV resistant art resin, and a doming effect for a beautiful finish.
