12-Pack of 10.1 Oz Sika 112718 AnchorFix-2 High Performance Construction Adhesive

Used to secure bolts holding newel posts into concrete. Worked great, posts are solid

Wish they sold smaller tubes but it works incredibly fast and strong.

I used this to anchor some screws in rocks that I then used for hanging beach towels for our outdoor shower. It comes with two mixing nozzles. I put the first one on, filled the hole, fiddled around putting the screw in and BOOM! that was it, no more product came out of the nozzle because it had hardened. I used the second nozzle and filled the other 5 holes quickly and was able to get everything done. Very expensive solution for what I was trying to do but very effective. I'm looking for a reusable alternative. It's quite possible, I'm missing something and this is reusable but I have no more nozzles - if it is reusable, let me know.

I had a cheap HF gun which couldn’t hack it, luckily my BIL had a very good one and that delivered the product just fine. It sets pretty fast even at 50º ambient but things can move for a while if not attended to.I set four 4x4 post bases that have a 9” rebar welded onto the bottom in a rock bald which was grey shale, it did not scale or shatter when I drilled it and remained very solid. I used a 1” bit to give me some wriggle room alignment wise, filled the holes 3/4’ full and pressed the bases in, a good bit flowed out the top as I set them. Over the next hour they shifted slightly and went out of alignment a tad but I coerced them back into place. They will be supporting an 8’x6’ covered porch so I probably didn’t need adhesive at all, the weight of the porch being what it is. The recommendation for a 3/4” post pin is a 7/8” hole but I didn’t have a 7/8” rotary hammer bit, only 3/4” and 1”, so 1” it was.I cut about 2” off the end of the mixing nozzle but didn’t cut back to the point where the mixing labyrinth is. I pumped out about 6” of product on a paper towel but should have done more, the gun wasn’t cooperating, by doing more it insures that only well-mixed product goes in the hole and more importantly stays in the nozzle - many people have trouble with the nozzle clogging but it’s often because they failed to follow the instructions on the tube imo. A high quality and high power caulk gun is mandatory imo.

For the last month, I have been trying to glue down some paver steps in my backyard. I have tried a half a dozen products, all of which were advertised as "strong adhesives" for pavers. None of them worked. I used this product today and it was unbelievable! It did everything I needed it to do. I knew as soon as I applied it and the pavers stuck that this product was probably going to work really well. It's a been a few hours now and those paver steps aren't going anywhere!Super pleased with this product! It's not the cheapest product on the market, but, boy, does it work. Given the amount of time I've spent applying and then removing other products, I should have bought this the first time. It was well worth the price!

I can see that is certain situations a fast setting epoxy is a good thing, but in my application it turned out to be an expensive mistake. I am setting an aluminum railing into granite steps. It is a custom made railing and the manufacturer recommended that I set the posts into the epoxy so I also fill the inside of the base of the post. I started filling the first hole with the epoxy and I quickly realized it was way too hard to pump the epoxy through the mixing tube fast enough. I was pumping the caulk gun with both hands to try and go faster. No luck. The epoxy had already started to harden before I could set the railing. I had to core drill the epoxy out of the hole and start over. A waste of time and money.

This was very easy to use and does not require a special gun , it works with a chalking gun and comes with 2 tips. Don’t forget to clean the hole prior to adding adhesive. Perfect for adding rebar, bolts to existing concrete. You can purchase extra tips online so if you don’t use the whole tube now anything not pumped out is not mixed and can be used later.

I followed the instructions, removed the cap, cut the bag below the clip, inserted in a caulking gun and started to squeeze out a little to get the mixing started. Literally 10 seconds or less later tried to squeeze into the hole I had pre drilled and it was already hard in the mixing tube. I cut the nozzle back 3 inches and it was still too hard to squeeze out, broke my gun. I tried the second nozzle and another caulking gun and got one hole filled before the epoxy was hard in the nozzle again. Decided to open the whole thing up squeeze out the epoxy on a board and give it a hand mix, dip the rebar into the mound of epoxy and push into the hole, this worked for 1 rebar and the whole mass was hard, what a waste.

Seems very strong but way too fast to cureI put it in the fridge but product is very hard and comes out very slowly. When in the concrete cure in one minute or less. Won’t give you much time to install carefully the bolts
