1:18 Scale Mini Cinder Block Mold

− +
This six piece cinder block mold is the same format we use to make our 1:18 scale CMUs. Made of silicone. You can pour almost any hardening material in here, and they will withstand up to 425ºF.
  • Works with concrete, plaster, or anything else you can think of!
  • Pour and scrape the top off to get nice flat cinder blocks
  • Extremely pliable for easy removal of blocks

Please note:

  • These are not made for mass production, they have a limited life-span.
  • These are not graded as food-safe molds. 
    Here's a video of how to use the mold!
