Great anchoring power. I installed a dancing pole on a concrete ceiling/floor with 1/2 bolts set in epoxy..
Lots of amateur reviewers who don't know how to use the product.
To get it to dispense easier, soak the tube in boiling hot water for ten minutes, or, leave it in direct sunlight. It flows very poorly when cold. Check the expiry date, if its old, it will be too hard to dispense. At one HD, the entire stock was expired by a year.
If it doesn't fit your caulking gun, use a little common sense just cut 1" off the tube end.as the tube isn't full,
The dispensing tube starts to harden very quickly. Dispense the amount you need without the tube and mix it by hand.
Blow all the dust out of your pre-drilled hole. The dust will cause it not to adhere.

I followed the instructions and applied the anchoring epoxy on a warm day. The product came out of the tube reasonable well, but took more pressure than I expected based on my previous experience with similar products. I was dispensing the product fast, basically going from hole to hole with about 3 squeezes of product into each 5/8" dia x 8" deep concrete hole followed by pushing the rebar piece into the hole. However, the tube "froze" after dispensing only about 50% of the product.

Used this to cement in 4 threaded rod 8" deep in concrete. It worked beautifully, Easy to use. Set fast. Very hard when cured. Very satisfied. Low cost, quick, effective solution. I will do it this way next time.

Works great! I recently used this on a metal hand railing on a set of brick steps I was pointing up. I used the epoxy to fill the empty cavity where the railing is installed into the brick. I really secured the railing. I was impressed and will be using it again.
