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.

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
