Great stuff!!
I used this to fill the expansion joints in my driveway. They were all old and failing, peeling out. When I blew several out with my leaf blower I realized they need to be replaced. I chose this from recommendations of others I have talked to. Works fantastic!!

Great for my pool
We put this under the pool coping and after a hot dinner showed minimal cracking and had not peeled off at all. Should last another year or two before we may add another coat. Pretty easy to work with. Pleased with it.

Grey is very dark. Extremely hard to get off your hands
Color is way darker than I was expecting . Applied very dark gray lightens up a little when dry. Worked well vertical application at the top of the tile to the coping stones on our pool Caution extremely hard to get off of your hands and skin.

Adheres well and does the job with ease.
Purchased to seal a concrete slab for radon mitigation. Adhers well and extrudes easily when warmed up. Dry time varies with thickness but provides plenty of time to work in crevices and joints. I've used other Sika products with great success and am confident this is the same. Great savings when buying bulk as compared to the big box stores.

Great filling cracks in the driveway
Do not have any of this on your hands when you scratch your nuts. I walked around for three days stuck to my beanbag.🤣
