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
Concrete Mixing Bag
The Reusable Concrete Mixing Bag eliminates the need for a concrete mixer or wheelbarrow.
Empty a 40, 60, or 80lb bag of concrete into the mixing bag, add water, twist the bag closed, and shake. Once you are done using, lay the bag flat and let dry overnight. The next day, empty the dried concrete contents into a trashcan - clean-up is that easy!
We love this bag, and often prefer using this over our concrete mixer!
Slater Atlas Stone Lightening Insert
Lighten your atlas stone by adding a High Density Lightening Insert to the mix. 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.

Stage 1 Stone Mold Accessory Kit
Combined with a Slater’s Atlas Stone Mold, this kit allows you to make a great atlas stone. Included in the kit are two bags of Concrete Strengthening Fibers, an 11oz Can of Stone Mold Release, and a Roll of Gorilla Tape. Over a 20% savings compared to individual pricing.
Blaster Stone Mold Release
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.
Hydraulic Cement (Atlas Stone Patch)
This product works well for patching small holes in Atlas Stones. This is very strong stuff, and expands as it sets to provide a permanent, high strength, fast-setting patch on atlas stones, cracks in concrete, masonry walls, wall-floor joints, swimming pools, water storage tanks, fountains, ponds, and drains. Ready to mix with water.
One pound fills a crack 3/4"W x 3/4"D x 2.5' length, or 16.8 cubic inches.
High Performance Mold Release
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.
5-QT Concrete Mix Measuring Container
The 5-Quart Mix Measuring Container is great for adding water to the mix, producing concrete with the perfect consistency. Fill with the correct amount of water and mix with dry concrete. This mixing container works especially well with our Concrete Mixing Bag.
Custom Stone Mold Lettering
Add custom stone mold lettering to your Slater Atlas Stone Mold! Lettering is limited to 25 characters. We guarantee that the lettering will hold for at least one atlas stone. If placing an order for multiple stone molds, you should purchase the same amount of labels as molds, or specify which mold you would like the label installed.
When placing an order, please include what you would like your lettering to read in the order notes located on checkout page. For questions, please email firstname.lastname@example.org
Mold Tape (Gorilla Style)
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.
1.88" wide x 35 yards long
17 mil thick
Tight weave, reinforced backing
Stone Mold Shrink Wrap
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!
This roll contains 1,000 feet of 5" wrap, costing about .50 per mold.
