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

Nunca había utilizado un anclaje químico y me sorprendió, tanto lo fuerte que es como lo fácil que utiliza, perforas, limpia muy bien la zona, colócales el producto dejas secar y al cabo de un par de horas está listo para trabajar

As this uses a standard caulk gun handling it isn’t cumbersome. Be sure to trim the staple binding before you install the mixing tip. Works great but be aware that this stuff sets very quickly!!!

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

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.

llega sin el aplicador y no hay manera de usarlo así. Alguien se los queda.
