Great product, withstands weather conditions great !
Durable product, color does match as advertised, thickness is very thick, does seal concrete as advertised great, easy to use load in gun and proceed with project, recommend size now my personal opinion is for a smaller project due to does not last forever will possibly need more then one tube but is very strong, durable to weather conditions and I would recommend

The sealant that stuck with me literally
If duct tape had a smarter, stronger cousin who went to trade school and never calls out of work—it would be Sikaflex.I used this stuff to seal a gap in my foundation, and it stuck like it had a personal vendetta against air leaks. It’s thick, weatherproof, and so sticky I’m pretty sure if I dropped it on my driveway, it would become part of the driveway.It cures slow enough that you have time to fix mistakes (thanks for understanding, Sikaflex), but once it sets? Game over, that joint isn’t going anywhere. Wind, rain, time, regret—nothing breaks this bond.Word of warning: wear gloves unless you enjoy explaining to people why your hands look like you lost a fight with a tar pit.Whether you’re sealing cracks, joints, or a DIY mistake you swore you could handle alone—this stuff’s got your back.

Easier to use than ordinary concrete cauik
We have used this Silka Concrete fixer to fill in the expansion joints around our sidewalks and driveway. We first cleaned out all of the old "caulk" and debris, then applied this new caulk. Because of it's consistency I found that it is so much easier to use with a caulk gun. When you release the trigger and back off the plunger, the caulk stops coming out. This made the job so much easier. I was able to use the back of a plastic spoon the smooth out the caulk.

Hard to dispense out of the tube.
Seems to work well, but is ridiculously difficult to dispense.
