Project Prep

  1. Ensure that the holes are wide and deep enough to provide proper support. Diameter of the holes should be 3 to 4 times the diameter of the rebar being placed, and the depth of the holes must be 8 to 12 times the rebar’s diameter.
  2. To achieve optimum performance of the anchoring epoxy, scuff, wire brush, or sand the holes and surfaces prior to product application. Surfaces and holes should be dust-free and cleaned of all surface contaminants, such as grease, oil, water, or dirt. Remove all loose debris from drilled holes using a blower or vacuum.
  3. Choose the right epoxy anchor formulation. Sakrete offers two types: High Strength and Rapid-Setting. Both end up at 10,000 psi. The High Strength is a 24-hour set, whereas at 10 hours we have full strength with Rapid Set.
  4. Unscrew the top of the epoxy cartridge, but don’t discard it. Pull out the plug. The plug and the cap are to allow you a re-use. Thread it down tight when you’re done to keep it water tight and air tight.
  5. Pull off the nozzle. This is a one-use nozzle, but the cartridge can be used again. You simply thread it onto the existing threads on the container, the cartridge, get it tight.

Safety Notes: Read and understand the SDS before using this product. Wear protective clothing and equipment. Keep out of reach of children.

Project Tip: Make sure to clean any surface or hole where the anchoring epoxy will make contact for better results.


  1. Insert the cartridge into your caulk gun. As you squeeze, you’ll notice that there’s two different colors of material coming out because this is a mixing tip. When it reaches the end, it’s going to be consolidated.
  2. Squeeze a sample out onto some kind of a scrap paper, whatever you’ve got on the job site. You should see a uniform gray, indicating that the epoxy is mixed and ready to use.

Project Tip: Use a pro-grade caulk gun with a 12:1 mechanical ratio for best results.


  1. Start by filling the hole where the rebar will be placed. Avoid the temptation to fill it all the way up, as you’ve got to account for the displacement that the rebar is going to cause. Fill it up maybe halfway.
  2. Start at the bottom of the hole, be careful not to leave any air pockets or voids while filling and pull up about halfway. Take the pressure off.

Project Tip: Don’t overfill!


  1. Insert the rebar into the hole. Always remember to twist it back and forth. You’re locking it in, the torsion is there. The epoxy should rise all the way up to the rim. If you need to put a dab, you can but for all intents and purposes this hole is filled.


  1. Allow the epoxy to cure.
    • The time this takes will depend on the type of epoxy you used. With the Rapid Setting, you can go ahead and start wiring the basket in today. Cure time to ultimate strength is 10 hours at 75°F (24°C) and 8 hours at 110°F (43°C).
    • With the High Strength, you need to just set your rebar, come back the next morning and begin the job.
