Our 10” Slater Atlas Stone Mold produces a concrete Atlas Stone that weighs approximately 45 lbs. All Slater Atlas Stone Molds are designed to be multiple-use products, with some users claiming to have to have made over 50 stones from the same mold. Available in 10 size options ranging from 8" to 24" in diameter, our Stone Molds cater to a wide range of weight preferences, from approximately 23 lbs to 586 lbs. Your Mold will come with easy-to-follow instructions, enabling athletes - from beginners to seasoned pros - to save time while the mold does much of the work.

Recognized as the original and most durable Atlas Stone Mold in the strength industry, our molds are designed for making excellent competition-grade Atlas Stones with ease. Slater Molds have been trusted for creating the Atlas Stones for many of the world’s most prestigious strongman competitions.

Adjusting Your Stone's Weight:

• Due to the small size of the mold, we do not recommend using a lightening ball to lighten the stone. If you would like to make a lighter 10” Atlas Stone, we suggest using a lightweight concrete mix (Sakrete Maximizer Concrete Mix, etc.).

Customizations:

• We offer custom stone mold lettering, limited to 25 characters, allowing for personalization or branding of the stones. Customization can be added to your order by adding “Custom Stone Mold Lettering” to your cart through our product page. Custom Lettering comes in the form of a sticker placed on the inside of the mold, which will leave an impression on the completed stone. Custom Lettering is only guaranteed for one atlas stone.

Stone Mold Release is an absolute must-have for Atlas Stone making. Without lubricating the inside of the mold before pouring concrete, the two halves are very difficult to separate. Use Blaster Stone Mold Release to lubricate the two halves and prolong the life of the mold.

Elite Training Tacky is the most economical tacky on the market. This is a less viscous product than the Premium Elite Tacky, but applies and cleans up much easier. It was designed not only to be more cost efficient, but also as a bridge between chalk-only stone training and stone lifting with the premium tacky lines. This is also a great tacky for novice stone lifters as well as large training groups who consume bulk amounts of tacky. Training Tacky is best-used in temperatures greater than 50 degrees F. 

As with all tacky, it is recommended to store with the lid on and out of sunlight to prolong the consistency.

A little goes a long way! Use High-Performance Mold Release to make taking the mold off of the stone a breeze!

Lightly spray the lubricant on the inside of the mold, spread it will a paper towel, and carry on with the rest of the mold assembly process.

The absolute best tape to use on your Slater Atlas Stone Mold. We so strongly recommend using this tape that we do not sell any other tape on our website, nor use any other tape in our stone-making. By our best estimate, using Gorilla Tape on your mold only costs $1.15 per stone. 

Specs:

• 1.88" wide x 30 yards long
• 17 mil thick 
• Tight weave, reinforced backing
• Weather-resistant shell 

Lighten your atlas stone by adding a High Density Foam Lightening Insert to the mix. We use high quality foam so the heat caused from the curing of the concrete does not degrade the foam in concrete. We recommend planning to leave at least 4" of concrete on either side of the insert to reduce the risk of the stone breaking. We also recommend including Concrete Strengthening Fibers and a high strength concrete mix (Quikrete 5000, etc.) if adding a lightening insert to the stone. Instructions for installing Lightening Inserts are mentioned in the instruction sheet included with each order, or can be found here. 

Use to shrink wrap your molds after taping them and prior to filling them with concrete.The shrink wrap is great for extra support and works especially well to help keep your molds clean. Just cut the wrap off after your concrete is set up and your mold is still clean!

Include our large-poly, super-strong polypropylene/polyethylene blended synthetic macro-fibers in your concrete mix to assure the strongest possible stone. These fibers act like mini re-bar, successfully replacing steel fibers, welded wire mesh, and conventional reinforcing bars in the stone. Fibers increase overall durability, fatigue resistance, and flexural toughness of the stone. Bulk mixture includes (1) 12oz bulk bag or box of fibers, equivalent to around 8 small bags of fibers. 

Small Bag - Include with wet concrete mix:

• 8"-12" Stone: 1/2 Bag
• 14"-18" Stone: 1 Bag
• 20"-24" Stone: 2 Bags

Bulk Box - Include with wet concrete mix:

• 8"-12" Stone: Small Handful
• 14"-18" Stone: Large Handful
• 20"-24" Stone: Two Large Handfuls
