No. Eight inches is the absolute minimum. The thicker the concrete is, the more product is used, thus giving more expansive force. THE CRACKER® can be used up to ten feet. Click here to link to our Cracker technical data sheet.
Most of our products have been designed and tested for use in concrete. While we have no testing for use in conjunction with other substrates or materials, we have received many reports of various successes in other substrates. Do not use on untested materials in applications which could cause injury in the event of a bond failure with the substrate.
It is always best to clean the tool before the epoxy cures. Otherwise, Xylene, WD40 or alcohol will help to some degree. Try scraping cured epoxy off with a sharp knife or other sharp utensil. Otherwise, mild solvents may help to some degree.
Horizontal slicing of minimal thicknesses is not the best application for THE CRACKER®. To slice concrete horizontally, holes would have to be drilled in from the side at an angle otherwise THE CRACKER® would not stay in the holes. The resulting cracked slice in the slab would occur at an angle. As an alternative, drilling in from the top would produce uneven crater like cracking.

Exposure to dampness or moisture during the application process will affect the curing of this product. Cracks or control joints being filled with CRACKBOND® JF311 should be completely dry before filling. Click here to link to our CRACKBOND® JF311 technical data sheet.
Most likely it is too cold. The cartridges need to be warmed before use. All epoxies thicken in cooler temperatures and can become difficult to dispense. Try ULTRABOND® 365CC for ATC’s best all weather formula. This product can be dispensed down to 5°F without the need to warm the cartridge first.

This occurrence indicates that the cartridge was not balanced properly. This process involves dispensing a small amount of product first BEFORE attaching the nozzle. Then attach nozzle and dispense material until a uniform gray color is achieved without any streaks.
Most of Cracker failures occur because the correct amount of water was not used. It must be measured. When “eyeballing” it, more water is usually added than needed and the product fails. Otherwise the holes may not have been drilled deep enough or the hole spacing may have been too far apart. Click here to link to THE CRACKER® technical data sheet.
