• Can any of your formulas be used for under water anchoring/doweling applications?

      Most of our formulas are insensitive to moisture once cured however only Ultrabond 1 can be dispensed into fully submerged holes. Miraclebond, our general purpose repair epoxy will cure in damp or wet conditions and even underwater. Click here to link to our Ultrabond 1 technical data sheet.
    • Do you have a product with AC-308 approval?

      Yes, Ultrabond 4CC. Click here to link to our Ultrabond 4CC technical data sheet.
    • Can Miracle Bond be sanded?

      Yes sandpaper with a grit from 30-80 can be used with good results. Wear a mask to avoid particle inhalation. Click here to link to our MB1350 technical data sheet.
    • Can Miracle Bond be used in marine applications to repair holes in fiberglass?

      Yes. Click here to link to our MB1350 technical data sheet.
    • Can I use The Cracker to break up a sidewalk six inches thick?

      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 manual.
    • Can Crackbond JF311 be used in a vertical crack?

      No. It is a self leveling formula and would run down the wall. It is for horizontal applications only. Click here to link to our Crackbond JF311 technical data sheet.
    • Can I use Ultrabond epoxy to bond plastic, wood, fiberglass, rubber, stone, granite, etc.?

      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. Smooth materials should be roughened up. Do not use in untested materials in applications that could cause injury in the event of product failure.
    • Can Miracle Bond be polished like concrete in flooring applications?

      Yes. It produces glass-like results when polished.
    • Can I put a 1 inch dowel in a 2 inch oversized hole and use epoxy without any loss of strength?

      Yes. The recommended hole diameter is typically 1/16” – 1/4” larger than the threaded rod diameter (depending on the diameter of the rod or bar). Based on tests and various studies ICC (formerly ICBO) allows larger hole diameters up to 1-1/2 times the rod diameter without any reduction in tension and shear values.
    • How do I clean cured epoxy off of dispensing tools?

      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. Grinding or sanding off is another option.
    • Can I use The Cracker to remove the top 10 inches off a slab?

      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.

    • Miracle Bond is hard to dispense and will not come out of the cartridge

      ATC’s TM9HD dispensing tool must be used. It is a very thick non-sag product and is difficult to dispense with standard caulking guns. ATC’s TMHD tool has a 26:1 ratio that offers more fatigue free dispensing power.
    • What can cause bubbles or bubbling to appear in a Crackbond JF311 application?

      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.
    • I can only get half of the material out of my two part single cartridge system. What’s the problem?

      The material is fully dispensed when the plunger reaches halfway. This is due to our unique cartridge design. Click here to see a cutaway diagram of this cartridge.
    • Customer just called to inform us they can’t get the product to dispense out of the cartridge…….why?

      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 365 for ATC’s best all weather formula. This product can be dispensed down to 0°F without the need to warm the cartridge first.

    • Your epoxy is not curing properly. Some holes hardened and some did not.

      TThis occurrence indicates that the cartridge was probably not balanced properly. This process involves dispensing a small amount of product BEFORE attaching the nozzle and then dispensing until a uniform gray color is achieved with no streaks. After this step, attach the nozzle and dispense a small bead of product until a consistent color with no streaks is attained.
    • The Cracker failed to work. The concrete didn’t break. Why?

      95% 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 our Cracker technical manual.
