Resin waterfall – how to make a waterfall with clear resin

by Lynette Olnhausen


Supply list:

For this project, you’ll need:

Clear resin
Mixing cups and stir stix
Scallop or cockle shells
Clear plastic wrap
Small rocks and pebbles
Hot glue gun

Step 1

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

Begin attaching your rocks and pebbles to help hide the back of the shells (where the hot glue is obvious). You may also want to add some rocks 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

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

Start at the top of the plastic wrap, and add a thread of glue from the basin of the top shell 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 tip of the hot glue gun too close to the already cooled glue, as this can reheat the glue and allow it to re-liquify.

If you are unsatisfied with any of your streams, wait for the glue to cool and peel it off and try again.   Hot glue (once cooled) comes off relatively easily.

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. 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. 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 congeal 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 add little decorations to the bottom of your shells, such as sand, smaller shells, imitation plants, interesting rocks, pearls, molded animals, etc.

Your resin can also be colored blue to create an interesting effect.  Bubbles in your waterfall also create a more realistic look, in my personal opinion.


Pro tip:  Do not warm your resin for this project, as it will affect the glue streams.

Step 6

Make sure your piece is in an area where it won’t be able to easily tip over; it’s best if you put it in a resin safe container.  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 special 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.
