What is HydroCast?
HydroCast is a 3:1 mix ratio epoxy that provides a sustainable alternative to traditional resins. This mineral-based material effortlessly mimics stone’s appearance, composed of a casting compound and acrylic hardener for simplicity and sustainability combined.
Why should I use HydroCast?
It is more robust and less prone to yellowing compared to resin. It’s light weight nature, makes it perfect for weight-sensitive applications. Plus, its matte finish seamlessly complements any home decor.

What You Will Need
Step 1: Grab your Starter Kit
No need to worry about buying molds and colors, the starter kits includes everything you’ll need to start your first project!
Step 2: Measure out the Components
Measure out 3 parts of Part A the HydroCast Casting Compound (this is the powder) and 1 part of Part B the HydroCast Curing Catalyst (this is the liquid)
Step 3: Mix until Combined
Mix the two components together until fully combined
Step 4: Add your Colors
For this project we used a few drops of yellow and green, but you choose what you like! It’s your world we’re just living in it!
Step 5: Mix Slightly
For this project we wanted to create a marbled look. If that’s what you’re looking for, only mix the colors slightly. This way the colors are not fully combined, and we get that marbled effect.
Step 6: Pour your HydroCast
Pour your mixture into your desired mold. The starter kit comes with two already, but you can use whatever mold you love most!
* Pro Tip: tap the sides of your mold to release any air bubbles. we hate those pesky suckers round these parts
Step 7: Allow Time to Cure
Allow 24 hours for your HydroCast to set. Epoxy requires so much patience….ughhh
Step 8: Demold
Unveil your beautiful project and show it off!
Crafting Tip:
Feel free to experiment with different techniques, colors, and molds. Every piece is a unique expression of you!

Is this the same gypsum-based material as resincrete/eco-resin?
It will give a similar effect!
Is HydroCast okay for outdoor use when cured?
HydroCast is durable, flame-resistant, and gains water resistance with the addition of a sealer, making it ideal for a variety of projects! You can definitely use it outside once fully cured!
