FAQ

What is HydroCast?
✨ HydroCast is a sustainable, mineral-based casting compound that provides a greener alternative to traditional resins. With a 3:1 mix ratio, it’s easy to use and consists of a casting compound and an acrylic hardener, mimicking the appearance of stone. This eco-friendly material is perfect for various crafts and home décor projects.

Does it offer a more eco-friendly choice without compromising quality?
🪴 Yes! HydroCast’s sustainable formula provides a guilt-free crafting experience while ensuring high-quality results. It’s safe for indoor use, making it a sustainable choice without sacrificing durability or aesthetic appeal.

What makes HydroCast the ideal choice?
💫 HydroCast is stronger and less prone to yellowing compared to traditional resin. Its matte finish seamlessly complements home décor, and as a non-toxic resin alternative, it’s perfect for creating beautiful, long-lasting projects.

How durable are HydroCast projects?
🪨 Despite its sustainable formula, HydroCast does not compromise on durability. This mineral-based casting compound ensures long-lasting creations that are resistant to wear and tear, making it a reliable choice for crafting.

Is it suitable for making terrazzo chips?
🌈 Yes! HydroCast works well for creating custom terrazzo chips. Simply mix colored HydroCast, break or cut it into small pieces, and embed them into fresh HydroCast or other compatible materials to achieve a terrazzo-style effect. This eco-friendly material allows for customized chip size, color, and placement for unique, one-of-a-kind designs.

What causes spottiness in HydroCast?
⭕ To prevent a spotty appearance, ensure thorough mixing before pouring. It’s essential to mix HydroCast well to eliminate lumps and ensure even pigment distribution for a smooth, high-quality finish.

Can I mix acrylic paint with HydroCast?
🎨 Yes, but it’s important to use the right ratio. Adding too much paint, especially water-based acrylics, can interfere with the curing process. HydroCast works well with acrylic paint, alcohol inks, and mica powders, but HydroCast pigments offer richer, more vibrant colors compared to standard acrylics. Just a small drop can make a significant color difference.

How long should I wait before sanding, and what grit should I use?
🕒 Allow 24 hours before sanding your HydroCast projects. Start with 180 grit and gradually move to 400 grit for a smooth finish. Wet sanding is also an option for an even more refined surface.

When should I pour additional layers?
⌚ For best results, pour another layer within one hour, once the material reaches the tack-free stage. Waiting too long may require sanding before adding a new layer to ensure proper adhesion.

Is HydroCast fire-resistant and waterproof?
🔥 HydroCast is naturally fire-resistant due to its mineral-based composition. While it is not inherently waterproof, applying a suitable waterproof sealer can enhance its resistance to water. Be sure to choose a compatible sealer that maintains its fire-resistant properties.

This durable and sustainable casting material offers a safe and reliable solution for eco-conscious makers looking to create stunning projects.
