Sikaflex Concrete Fix Crack and Joint Sealant, Limestone, 10.1 fl oz

Works well so far. It's kind of a shiny metallic silver color if that matter to you. If it doesn't hold up, I'll update the review. I used it for the space between my garage apron and slab to keep water from running down in-between the two.

This and SIKA’s self leveling sealant both work very well to seal cracks in concrete. I found this easier to work with for thinner cracks than the self leveling sealant, since it is easier to control and stop the flow when not in use. The self leveling version works best when the entire caulk tip fits into the crack and the “flow” of the sealant can spread out into the crack and self level without making a mess. My only complaint is that the limestone color is really a light gray. It’s pretty much the same as the self leveling gray color and doesn’t blend perfectly with the limestone color of most concrete. For this, I would give it 4.5 stars. Tip: A little sand sprinkled and rubbed in after application helps it blend better with the concrete texture and color.

Lowkey impressed by this stuff. I slapped it on some crusty, cracked concrete that’s been giving “abandoned mall parking lot” vibes, and bro… it ate. The tube was a little messy (like, you WILL get some on your hands and question your life choices), but once it’s down, it’s locked in like a situationship you can’t escape. The texture? Thick. The hold? Thicker. It cures up solid and smooth, and suddenly my walkway went from “NPC spawn zone” to “main character energy.” Only reason it’s not a 5/5 is because squeezing it out feels like arm day at the gym, but honestly, that’s just the price of greatness. Verdict: Concrete cracks? Consider them ghosted. 4/5, would seal again.

This is my preferred choice for waterproof outdoor sealant, especially when binding deferring materials together. For this application I needed to bind an Aluminum door jam to a concrete footing. I also used it to bind 16 inch stepping stones to the same concrete footing to keep them from slipping away from the door. I sealed a crack in the footing to keep water and bugs from intruding. The sealant flows easily and is self leveling. For vertical cracks you may have to apply more than one coat as it begins to set up.

This product was recommended by our concrete guy as the only one to even both with. Other products do not perform well in application nor do they last like this one. Application was slightly gloppy but in following instructions it worked out well. Tube lasted further than we expected. No color match choices were available so it is too light but our concrete walk is 21 years old we are ok with that. The proof will be in over winter. If I can run my snow shovel over this area without catching & peeling it up I will call it a win. Check back in May!

Works very well on concrete

This stuff really worked.

Very difficult to use. Needed two hands on caulking gun to get out ofvthe tube. Used half a tube. I plugged tge tip. Came back later to finish the job. The sealant must have handed. I couldn't get it to come out of the tube. I threw it away and am stuck with 2 tube. Past return date. Live and learn.

Did not use it yet as it is too cold So i cannot say whether is good or bad.

Used this sealant to repair a few cracks around my concrete steps and seal some joints on an exterior wall. The application was straightforward, and the material came out of the cartridge smoothly without making a mess. It adhered very well to concrete and metal surfaces without needing any extra prep work. Once cured, it remained flexible while creating a strong, weatherproof seal. After a few days of rain and temperature changes, everything still looks great with no signs of cracking or shrinking. A durable, professional-quality product that saved me both time and effort on my repair project.

Lo usé para unas ranuras en la pared y funcionó bien, gran calidad de producto

Worked very well

Excelente sellador, solo hay que procurar limpiar bien la zona antes de aplicarlo para que el agarre sea mucho mejor, una vez que seca la adherencia es muy buena, en mi caso tuve que comprar 2 tubos porque la grieta que quería rellenar era demasiado grande y no me alcanzó para otras 2 grietas más que tenía
