Hard Cast – Professional Hard Casting Resin for Durable Art and Molds

Hard Cast from Counter Culture DIY is a high-strength casting resin engineered for artists and makers who demand durability and clarity. It’s a professional-grade epoxy designed for casting resin formulated to cure hard, smooth, and glass-clear for detailed art pieces, thick molds, and functional decor. Whether you’re pouring sculpture blocks, embedding objects, or creating custom resin art, Hard Cast gives you the strength and stability you need in every pour.

This resin for casting pours easily and self-levels beautifully, making it simple to achieve even coverage without bubbles or ripples. It’s VOC-free, low odor, and UV-resistant to help protect your artwork’s clarity and color over time. Designed for makers who want lasting results, Hard Cast is your go-to resin for deep, strong, and flawless creations.

Why Makers Choose Hard Cast

Hard Cast is built for performance and precision. Its advanced formulation cures harder than traditional casting resins, giving your projects a rigid, durable finish that holds shape and resists scratches. The slower working time allows bubbles to escape naturally, ensuring clear, solid results even in thick layers. The result is a cast that feels strong, looks brilliant, and stands the test of time.

Unlike flexible formulas, Hard Cast delivers the structure and density needed for professional art pieces, keepsakes, and molded decor. It’s ideal for anyone who wants maximum hardness and clarity without sacrificing ease of use.

Available Sizes

32 oz Kit – 16 oz Part A + 16 oz Part B
1 Gallon Kit – ½ gal Part A + ½ gal Part B
2 Gallon Kit – 1 gal Part A + 1 gal Part B
4 Gallon Kit – 2 gal Part A + 2 gal Part B

Each kit is precisely balanced for 1:1 mixing by volume, ensuring consistent curing and dependable results.

Best Uses

Hard Cast is designed for solid castings, detailed molds, and artistic creations that require strength and clarity. Perfect for:

Thick mold pours and solid castings up to 1 inch per layer
Functional art, sculpture pieces, and home decor
Clear embedded objects and layered art blocks
Tabletop or panel casting where structure is essential
Projects that need a rigid, scratch-resistant finish

For larger surface areas, pour in thinner layers to prevent excess heat. For topcoats or glossy finishes, use Artist Resin. To seal your base before pouring, apply Quick Coat for the best adhesion and bubble control.

Pro Tips

Mix equal parts of Part A and Part B by volume. Stir slowly for 3–5 minutes, scraping the sides and bottom of your container for a complete mix. Avoid whipping air into the resin. For best results, mix at least 2 oz total. Pour in layers up to 1 inch thick, allowing each layer to partially cure before adding the next for the clearest finish.

Work in a temperature-controlled room for optimal results. Plan your project with the Resin Calculator to determine exactly how much resin you need for your mold or casting. Explore more Casting Resin Supplies to complete your setup with pigments, tools, and accessories.

Recommended Maximum Pour Depth: 1 inch per layer (thinner for wide pours)

Hard Cast cures to a strong, rigid finish that’s crystal-clear, heat-resistant, and scratch-resistant. It’s the ideal choice for any project that requires structural strength and professional results.
