What’s Needed To Make DIY Atlas Stones? Before you get started making your new stones you’ll want to make sure you’ve got all your supplies gathered and ready. Here is a checklist you can follow to make sure you get the best results possible:

  • Rubber gloves. 
  • Zip ties to hold the two sides of the mold together.
  • Scissors to cut zip ties after stones are cured. 
  • Silicone lubricant. Add a generous layer to the inside of your mold before pouring the concrete to allow the molds to release from the cured stone.
  • Quikrete concrete mix and something to mix it in such as a mixing bag or wheel barrow. Mix thoroughly to make sure all clumps are removed. 
  • Painters mask to avoid breathing in concrete dust. 
  • Optional – Nylon concrete fibers to mix into your concrete will make your stone more resistant to cracking, abrasion and impact. 
  • 5-gallon buckets to set the molds on while you pour the concrete and while the stones cure.
  • Screwdriver and rubber mallet to help release the molds after they are fully cured.

  • Molds are Made In The USA from ABS plastic.
  • Stone Weight Accuracy: Approx. +/- 5 lbs. of stated weight depending on the type of concrete that is used and how well it is compacted during the pouring process. 
  • Concrete Type: We recommend Quikrete 5000 because it’s affordable, strong, and consistent.
  • Cure Time: The stone should sit in the mold for 3-days. Once it’s taken out of the mold it should continue to cure for another 10 days BEFORE using.
  • Mold Life: There is no limit to how many times each mold can be used as long as it’s properly cleaned/maintained immediately after each use.  We’ve poured 50+ stones using a single mold. 
  • Lubricant: We recommend using a generous amount of lubricant, such as silicone spray, to lubricate the inside of the molds before adding concrete so that the molds will release from the cured concrete stone. If no lubricant is used the molds may not be able to be seperated from the cured concrete. 
  • Care: Always fully clean the inside of your molds immediately after each stone is cured. Doing so will prolong the life of your molds. 
  • Mold Width: Add 2” to the diameter of each stone (flange is 1”).
  • Mold Height: Divide the mold diameter by 2 and add 1”
  • Each set of molds includes two hemispheres of the mold ONLY. Purchase the concrete and all supplies separately.
