Anchoring Epoxy & Pre Cut Anchor Rod
anchoring epoxy is used to ensure that anchors maintain a secure grip. Mechanical anchors usually expand through being tightened or the use of an expander plug, which causes stress on the surrounding material. The stress can lead to cracks and breakage to weaker base materials. Because epoxy is a chemical anchor, however, it puts no setting stress on the material around it.
With anchoring epoxy, the resin and hardening agent mix as they are dispensed from a two-cartridge container through a special mixing nozzle and into the drilled hole in the concrete. After the anchor is installed, the epoxy expands and hardens to fill all available space and apply additional pressure to the anchor for added grip strength.
Installing Concrete Anchors with Epoxy
When installing anchors and threaded fasteners into concrete surfaces, safety is key. Following correct procedures and safety measures will ensure that the epoxy maintains its strong hold.
To install anchoring epoxy: Follow the manufactures pre-printed instructions on the tube, however below is a listing of the general sequence.
- Drill a hole slightly larger in diameter (about 1/16 to ¼ inch larger) than the concrete anchor you are setting. -See manufacturer’s instructions.
- Clear the hole of any remaining dust using compressed air and a nylon brush for excess debris. -Follow manufacturer’s instructions.
- Connect the epoxy cartridge to a caulk gun equipped to handle a significant amount of force. Remove the plastic tip from the anchoring epoxy. Note some brands require a brand specific caulk gun.
- Test the epoxy cartridge by squeezing a small amount into a disposable container until the flow of both black and white materials is even.
- Attach the static mixer nozzle to the epoxy cartridge and, once again, test the dispenser by squeezing a small amount until the two colors mix evenly.
- Fill your drilled hole about ½ to 2/3 full. Do not fill the hole completely with epoxy unless you are filling underwater.
- Turning clockwise, insert the concrete anchor rod you are attaching into the hole and remove any excess epoxy with a putty knife or piece of cardboard. Be careful not to touch the anchoring epoxy with exposed skin to prevent allergic reactions.
- Allow the epoxy to completely cure. This can take anywhere from 5 to 7 minutes, possibly longer if the temperature in the room is below 40 degrees. –Refer to manufacturer’s instructions.
- Remove the static mixer nozzle from the cartridge and return the cap.
- Always store your epoxy at the recommended temperatures.
Applications for Anchoring Epoxy
Concrete epoxy has many uses in home building and improvement. For projects that will be interacting with heavy loads or vibration, anchoring epoxy provides the strongest grip.

- Anchoring Epoxy: These high-strength, fast-curing adhesives enhance concrete anchors’ grip strength and help prevent pullout. We carry Red Head®, Powers®, and Simpson® brand anchor epoxies.
- Epoxy Mixing Nozzles: One-piece dispensing nozzles are designed to mix epoxy resin and hardening agent at the point of application. Nozzle attaches directly to epoxy cartridge for easy dispensing.
- Epoxy Screens:screen can be inserted into drilled holes in hollow base materials prior to epoxy application for improved grip. The screen material provides surface area for the epoxy to adhere to, while preventing the epoxy from flowing into larger voids where it would be wasted.
- Cleaning Brushes: Drilled holes must be thoroughly cleaned before applying anchoring epoxy. These durable, reusable hole cleaning brushes feature twisted wire handles and nylon bristles. Always follow manufacturer’s installation instructions.
- Piston Plugs: Used for overhead applications and vertical applications to ensure a uniform disbursement of the epoxy in the anchor hole, preventing air gaps.
