Making A Resin Waterfall Doesn’t Have To Be Hard

Have you ever mixed resin only to wonder if you can use it to make a waterfall? Like how can you freeze that crystal-clear epoxy into something that looks pulled from nature?  I’m going to show you how.

Supply list:

Crystal doming resin
Mixing cups
Stirring sticks
Scallop or cockle shells
Clear plastic wrap
Small rocks and pebbles
Hot glue gun

Step 1: Glue shells together

Select at least three shells that are slightly different sizes. Use your hot glue gun to glue the largest shell to the second-largest shell. Once that’s dried, glue the two shells to the smallest shell (or next largest shell). Wait for the glue to dry. Once dry, remove any extra threads of glue.

Step 2: Attach rocks

Glue rocks and pebbles to help hide the back of the shells where the hot glue is obvious. You may also want to add gravel to the bottom of the piece to help keep it level. Add pebbles into the areas where there are gaps. Wait for the glue to dry. Again, once dry, remove any extra glue threads.

Step 3: Attach plastic wrap

Cut some small pieces of clear plastic wrap. You’ll need enough to securely attach the top and bottom of the wrap from one shell basin to the other. Use the hot glue gun to attach the pieces. Wait for the glue to dry and remove any extra threads.

Step 4; Add glue to the plastic wrap

Start at the top of the plastic wrap. Then, add a glue thread from the top shell basin to the bottom of the following shell. Once the glue is cooled and dry, add another layer from top to bottom. Be careful not to get the hot glue gun tip too close to the already cooled glue. This can reheat the glue and allow it to re-liquify.

If you are unhappy with any of your streams, wait for the glue to cool, peel it off, and try again. Once hot glue cools, it comes off relatively quickly.

Once you’re happy with how your streams look, you can use the tip of the hot glue gun to do some touching up. For example, you can use it to melt any extra clear wrap or mold some of the cooled glue into place.

Larger streams can be a little tricky. I recommend adding one stream, then adding another stream next to it (without touching the other stream), and so on, until you’ve gone as wide as you would like. Then, once those streams are set, glue streams between each of the individual streams. Again, it’s best to create a support structure rather than trying to get it done all at once.

Once the streams are in place, prepare your resin. You want to mix the crystal doming resin for this project because it mixes thick. Casting resin mixes too thin and won’t make a waterfall when you add it to the plastic wrap.

Make sure to wear protective gloves when working with resin.

When your resin is mixed, use a pipette to add resin along the glue streams. It can be beneficial to let your resin sit for a bit and thicken when doing this process, as it clings to the glue better.

Make sure not to add so much resin that your shells overflow. You can also add decorations to the bottom of your shells, such as sand, smaller shells, imitation plants, interesting rocks, pearls, molded animals, etc.

You can also color your resin blue to create an interesting effect. I think bubbles in your waterfall also form a more realistic look.


Pro tip:  Do not warm your resin for this project. You want thick resin for this waterfall.

Make sure your piece is in an area where it won’t be able to tip over easily while it cures. Cover your piece with foil and allow the resin to cure.

Once cured, your resin waterfall is ready for display.

It would look great on a desk or shelf as a unique adornment.

Bonus tip: You can use resin molds to create a pool into which the waterfall flows.

This resin waterfall would also look great as a part of a terrarium.

  1. Instead of using Saran Wrap, I used thin flexible resin I peeled off one of my silicone Matts and layered the resin down the falls over a couple of hours as I worked on other projects. Pretty cool!!
    Wanted to add a photo but wouldn’t let me.
