Rated 1.0 out of 5.0 by Reid Must have gotten a bad tube
It just never set fully. Enormous pain to redo. I got another tube and it set so fast I could barely get it out fast enough.

Rated 5.0 out of 5.0 by NotoriousDBA So glad I found this product!
I was working on building wood railings for my front steps, and struggling with how to fasten the posts to the steps' concrete. In particular, the manufacturer of the post anchors I was using to mount the back posts to the top of the slab recommended using a specific concrete screw, but those were a complete no-go in 50+ year old concrete containing granite aggregate (believe me - I tried). Beyond that, lag screws w/ lag shields seemed like a really poor choice for fastening the other posts to the sides of the steps (you know they're going to fail eventually - they always do). After doing some research I found this Sika product, and decided to give it a shot. It was dead simple to use, and the attachment of my railings to the steps is ROCK SOLID. Those babies aren't going anywhere, at least not in my lifetime.
A few notes:
- Sure, it sets up relatively quickly, but in minutes, not seconds, just as advertised.
- Any decent quality caulk gun works fine. I didn't have any trouble dispensing the product.
- Be sure to have everything fully prepared before you start, because once you start, there's no going back.
- If you're a weekend warrior like me, or simply haven't used the product before, I would highly recommend doing a dry run of the whole installation before you crack the seal and get down to business. Doing this helped me avoid a couple of nasty surprises that would have caused real problems.
Bottom line: much stronger than any mechanical fastener I could find on the market, and much, much easier to use to boot. If I had to do something similar in the future, I wouldn't consider using anything else.

Rated 5.0 out of 5.0 by Pineisland Did the job
After reviewing the prior reviews I made sure I was ready with each piece of (#4) rebar. Each hole (4) was drilled, vacuumed out, brushed out and vacuumed again. I have a regular caulk gun and it handled the epoxy with ease. I filled the hole with epoxy, placed the rebar in the hole, twisted it and moved on to the next one. By the time I was filling the third hole, the first hole had already set up. No surprise due to the prior reviews. I used about half a tube on four holes, each 6" deep. I secured the cap on the tube, however, since one review said you only get about half a tube due to the way the plunger works, I'm not sure if I'll be able to use the tube again. I do have a second nozzle - so - we shall see. Like the prior reviews stated, be prepared, this stuff sets up quickly (within 3 minutes) and dries as hard as iron - once set you WON'T be pulling it back out.. This stuff is extremely pricey - but - you don't have much choice if your looking to do a job right.

User beware. This epoxy sets really fast, within seconds of dispensing. This is good so you don't have to stand holding the rebar, threaded rod etc for minutes while it sets. It I also very, very bad for the applicator nozzle as the epoxy hardens inside it and you can't use it again. Other review say 5 minutes to set. Not in my case and none said anything about hardening in nozzle.
In my case was setting rebar in existing footing for masonry block tile wall. Epoxy came easy and set the rebar in the first hole, checked for plumb, then walked over to the next hole a couple of feet away. Not more than several minutes and had to struggle getting the epoxy out and had to use two hands to squeeze the caulk gun handle. Got the epoxy out, set the second rebar, check for plumb. Third hole, not happening. Epoxy had fully hardened in applicator nozzle. Cut nozzle open in sections almost all the way to base where the two parts first come together in the spiral portion. Rock solid and not even a 1/4 tube used. Was thinking of just squeezing 2 parts into hole and mixing with rebar until set but wasn't sure the portions would be correct. Knew wouldn't work with mixing board as would harden before getting down hole. Instead, got neighbor's help. Good thing 2 nozzles come with tube. Used second nozzle and went down line just squeezing in epoxy and dropping in rebar. Neighbor followed behind setting them plumb. Only 4 more holes but by 3rd hole he was struggling to set plumb. I did the last hole so not too bad. Only 2/3 of tube used. Threw away tube as no more nozzles. What a waste.
I suppose if you only had one hole/rebar to set or several where plumb isn't important it would be okay, but work very fast. Also plan on not being able to use remainder of tube even with 2 nozzles as no guarantee won't harden at tube outlet and you can't buy additional nozzles.

Rated 4.0 out of 5.0 by DIYer Bondo in a tube
I was first impressed with the packaging, it's a sausage tube inside the outer round tube with contents that mix together when swirled through the unique application tip. Novel!
It worked pretty much as expected, even on a 50ish degree morning, it was setting up quickly (I used the tube as supplied at it's smallest opening).
As I was using it I noticed a very familiar smell.... Bondo! I then looked at the dried product I had first squeezed out, and, yep! hard like plastic Bondo, broke apart like Bondo. I am convinced it's a version of Bondo in a tube.
I did some research and sure enough, 3M on their website recommends their version of Bondo (body filler) for permanent concrete repairs.
I AM NOT saying to substitute body filler, I am stating it appears to have many characteristics, and possibly using body filler could be a substitute for some applications. Maybe. Google and see.
That said, you are paying quite handsomely for a novel way to dispense body filler.

Rated 5.0 out of 5.0 by JuanL Two thumbs up!
Great product! Sets fast and hard as a rock, I used it to anchor some rebar into an existing piece of concrete and it did the job! Thanks Home Depot and Sika for a great product.

Rated 4.0 out of 5.0 by MarkS Heavy Duty Caulk Gun Required
I broke three caulk guns trying to dispense the fastener anchoring version of Sika epoxy. One gun was a composite Work Force ratchet gun from Home Depot, the other a standard metal caulk gun from Home Depot. The third was a medium duty gun from Lowe's. The trigger buckled on the first pull. I note that none of the Home Depot guns have a rating on the tags. The guns at Lowe's do but the Lowe's near me did not have a heavy duty gun for 10 oz tubes. One reviewer noted a standard gun would work. He must have better standard guns than Home Depot sells. My Home Depot does not stock a gun that will last to dispense one tube of this epoxy and Home Depot needs to fix that.

Rated 5.0 out of 5.0 by Peter1 Excellent stuff, squeezes out easily, but sets FAST
Worked great for setting 18 threaded rods of 1/4 diameter. Squeezes easily and smoothly, I was scared by some other products reviews saying people are breaking their caulk guns, so I got an expensive heavy duty one. Now I realize that I totally didn't need it, a standard gun would do the job. Sets FAST, on a warm day in ~5 min is hard as rock, so be prepared to go faster than it sets. Tube comes with 2 nozzles, I used half of it, hopefully I'll be able to use the rest later. Hardened squeeze-outs can be removed with a file, metal-cutting saw blade or grinder.
