Great stuff for Pool Decking
Great stuff. I used it to seal seam between the concrete deck and my pool tiles. Worked great. Not sure why they say it's self-leveling because it stayed in place on an overhead application. I used painters' tape on the vertical tiles to get a nice clean line.

Excellent product but incorrect description
I did not even attempt to use the Sikaflex until over a year after I purchased it, and then discovered that it expired one week after I bought it. So, it was over a year past expiration. But to my surprise, it was still in good condition! Very tough, strong adhesion, but Amazonās description says itās self-leveling, which it is not. I used it to bond shoe soles, seal leaks, and a tough caulking compound. A very good product that I will probably buy again.

Not self leveling!
Incorrect product description. After applying the product, I realized that it is not self leveling and had to be tooled and shaped which made a huge mess. Contacted customer service and the agent has not a clue what self leveling even means. She just wants to give me $5 for my troubles and issue a return. Why would Amazon make a customer return a used tube of sealant that is open? It will make a huge mess during shipping and will just end up in the landfill. Not to mention the hassle. Not the best way to keep costs down and customers happy Amazon. Fix the description so that people are buying the correct item in the first place. Itās like trying to get a customer to rip out wall paper and return it just for the sake of returning. That is not customer service, but again, most of the agents have zero common sense, they donāt know the products and just read the same script whether youāre returning an already applied sealant or a modem.

This sika is probably the best one out there. Bought 5 of these, enough to seal a lot of cement gaps and cracks on my driveway. I'm in BC Canada and it rains quite a lot. I'm finding this product attaches itself to the surrounding concrete better than other sealants and creates a solid barrier to prevent water from getting thru. I got the dark gray colour and it blends well with existing concrete. 5 of 5 stars!
