Block Buddy silicone mold

Mold suitable for use with concrete, Jesmonite, resin, and similar casting materials. Designed and perfected in-house, this mold delivers consistently clean results, is easy to demold, simple to clean, and fully reusable.

These molds have been used and tested multiple times by us, with great results. The finished cast stands perfectly upright once removed from the mold, without wobbling.

We use approximately 300 g of liquid Jesmonite AC100, though the volume can be adjusted depending on your preferred material and finish.

The final cast measures 24 × 15.5 × 3.5 cm.

Some molds include a supportive outer case, making them easier and more comfortable to handle during casting.

As we are discontinuing this product, only 4 molds are available.

Important note:
While we have never experienced any issues and have taken great care to perfect this mold, it is sold for personal and creative use. We do not advise using this mold for large-scale or commercial production but it's entirely up to the buyer to decide how to use.

Please allow for minor dimensional variations inherent to handmade molds (±1–3 mm).
