SIKAflex Self Leveling Sealant, Sandstone, Polyurethane with an Accelerated Curing Capacity for Sealing Horizontal Expansion Joints in Concrete, 29 fl. oz Cartridge

Sika is the only brand that had the color shade I needed, and the self leveling was very effective in filling very skinny cracks in garage floor. The tube requires an extra large caulking gun that I do not have. So I was able to push it out of the tube from the bottom with my hand given the lighter weight liquid consistency. Very pleased with the result. Dry time is definitely 24 hours before a car can drive over it.

Just the right sealant I needed, I like the self leveling action. Just make sure you clean the gap/crack then pour it

This stuff is the business! The neatest expansion joints you’ll ever see, and all without any tape or tooling. It’s a bit pricey, that’s for sure. And you’ll need an American sized 29oz caulk gun, but just wow. So easy to use.

This stuff was better than I thought it would be! I actually didn't use it for concrete I used it in between two layers of mahogany trim on the hull of a 12 foot fiberglass boat. Outside of the fact it took three days to cure enough to sand it is the exact result I was looking for. There were a couple places where the wood trim was damaged underneath and it leaked down the side of the hull, Where I was able to see it it cleaned up nicely with water and a rag where I didn't see it and it cured It was more difficult to remove I was able to do it with a razor blade. I havent finidhed yet to show the final result / Update The product hardened up nice and was easy to sand (didnt even clog the paper. Only issue the Epoxy Did NOT cover this product It Pooled up and cured in a sporatic patern. I would still buy again... it would be nice if I could figure out why the epoxy would not cover and fix that..

This product is so much better than my highest expectations despite my high regard for Sika products. It is so forgiving to work with and literally gives one so much time to make corrections. The reason being it only skins much later than one would expect. Quite extraordinary.
