Good sealer for construction.
Foundation to bottom frame plate sealer. Works very well, easy to use; comes out nice and thick, not runny; easy to work with and clean. It also stays elastic and does not dry rock hard. Sika isn't as well-known, but they make some of the best sealers and adhesives.

Wrong product
I've ordered Sikalflex 1A twice before from this seller with no problems. Apparently, though, the third time is not the charm. I received Sikaflex 1C SL instead. The 1C product is self-leveling and useless for my intended application although I can employ it to seal from cracks in concrete flatwork so I kept it. Now the question is.....should I risk ordering again and hoping I get the 1A or go elsewhere?

Weatherability and length of protection
Sikaflex top of the line polyurethane you can smell it in the fumes it releases it is a potent combination and when it cures up it is Bomb proof

tubes were partially cured and would not flow
tubes were old stock and did not flow into cracks. I have purchased the same product from other seller and it worked great. These appear to be old and partially cured in the tube. DO NOT BUY FROM THIS SELLER
