Sika Anchorfix-2, super strength anchoring adhesive, Two component anchor system for threaded bars in uncracked concrete, 10.1 fl. Oz

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.

Seems very strong but way too fast to cure I 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

My Husband wanted to try this to help with a gate that he put up and in the cinderblock and I don’t know all the details but it’s been some months now and it’s done it’s job wonderfully!

I will take some ownership of this issue, but honestly I wasn't dawdling that long. I had four bolts to set in a wall. Pumped in the epoxy for the first and was a bit slow putting in the bolt. By the time I was working on the second the epoxy had already set up in the nozzle. Switched nozzles and managed to get #2 done but that was it. This stuff holds, but sets quickly.

This adhesive works great for securing anchors in concrete for installing my two post lift. First off this is hard to ouch thru the tube. I bought a powered caulking gun just for this job. With an assistant following me I was able to fill as many holes per tube with them inserting the bolts behind me. Does it setup fast yes does it hold tight yes. Torqued bolts t 120 ft pounds with no movement.
