How to Mix Deep Cast Resin

Using deep cast resin primarily involves accurately mixing the two components before pouring.

Deep cast resin is commonly used for creating thick, clear castings, encapsulation projects, and river tables. Proper mixing is essential for achieving a successful cure that provides a hard casting.

Mixing deep cast resin involves specific steps regarding ratio, order, and duration to ensure the two parts react correctly and cure into a solid piece.

Key Steps for Success

Follow these steps carefully for effective mixing and pouring:

1. Prepare Your Workspace: Ensure you have a clean, level area and all necessary safety equipment (gloves, eye protection, ventilation).

2. Measure Accurately: The correct mixing ratio is vital for the resin to cure properly. Based on the provided information, you should use:

   • 2 parts resin

   • 1 part hardener

   • This ratio is by volume.

   • A table can help visualize this:

     Component	Ratio (by Volume)
     Resin	2
     Hardener	1

3. Pour in the Correct Order: For optimal results, the mixing order matters.

   • Pour the hardener first.
   • Then, pour the resin.
   • Combining them in this sequence helps ensure proper dispersion.

4. Mix Thoroughly: Once the two parts are in the container, mix them carefully.

   • The mixed components should be thoroughly stirred for 3-4 minutes.
   • Stir slowly to minimize air bubbles, scraping the sides and bottom of the container to ensure all material is incorporated, achieving an even consistency.

5. Pour into Mold: Once mixed, the resin is ready to be poured into your mold or project area.

   • Be mindful of the maximum volume you can pour at one time. According to the reference, the maximum volume that can be poured in one go is 12 litres. This is important for managing exothermic heat generated during curing.

By following these mixing and initial pouring guidelines, you set the stage for the resin to cure correctly, resulting in a durable, hard casting.
