SIKA Sikaflex Self Leveling Sealant, Sandstone, 29 fl oz fL, Polyurethane, Sealing Horizontal Expansion Joints in Concrete, Accelerated Curing, Self-Leveling, Durable

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.

Professional-Quality Self-Leveling Sealant That Makes Concrete Repairs EasyI've used several products for sealing concrete joints over the years, and Sikaflex continues to be one of the brands I trust. This self-leveling polyurethane sealant flows nicely into horizontal expansion joints, creating a smooth, professional-looking finish without having to spend time tooling the surface by hand.The sealant adheres well to properly prepared concrete and cures into a flexible, waterproof joint that should hold up well to changing weather conditions. I also like that it can be painted after it has fully cured, making it easier to blend repairs into the surrounding concrete if desired.Application is straightforward with a standard caulking gun, and the narrow nozzle allows for good control. Just be sure to thoroughly clean the joint before applying the sealant, as good surface preparation makes a big difference in the final result.One thing to keep in mind is that this is a self-leveling product, so it's intended for horizontal joints only. It's not suitable for vertical surfaces because it will flow before curing. Wearing disposable gloves is also a good idea since polyurethane sealants can be messy to clean off your hands.Bottom Line: This is a high-quality, professional-grade concrete joint sealant that's easy to apply, self-levels beautifully, and cures into a durable, flexible, waterproof seal. It's an excellent choice for driveways, sidewalks, garage floors, and other concrete joints, making it an easy 5-star recommendation.

Excellent and does not crack at all during summer or winter extreme temperatures helps protecting weed growth in concrete cracks.

Love this product! Very pleased with the result. I’ve used it in several places now, including replacing the mastic around the pool deck. I will say it was packaged poorly, which caused damage to the nozzles on the tubes. All were bent upon opening the box, but I was able to straighten and make work.

I have used this already in sealing cracks between my house and sidewalk, also on concrete steps; flows very nicely making it easy to get a nice caulking line. Then it is self-leveling, so it melds into an even better looking seam. I hope that it holds up well. I had to order more, and when it arrived each tube was separated wrapped in plastic in case it leaked, thank you! that is a thoughtful addition.

Good product. Worked well.

This product is not for sealing vertical cracks and joints, horizontal only. I have a few wide gaps between slabs in my driveway and I was told that could undermine it and cause it to sink. I got some sand and filled in the gaps, leaving a half inch depth at the top. You put this stuff in your caulking gun and then basically just pour it in. It's a little thicker than honey and it will flow and fill in the area so you don't need to be as precise as with regular caulk. Just move along, allowing the caulk to ooze out as you go. It is self leveling and self sealing because it flows and makes contact with all the sides. It is supposed to remain stretchy and keep the water out for a long time. I can't say anything about that because I only just applied it but it has dried to a rubbery consistency and it looks great.

Works really good. Goes down like a thick shake and when it’s dry, there is a rubbery flex to it. I have not tried to paint over it yet. I’m using it to fill cracks in front of the garage. My only issue is when you get it use it right away. I bought two tubes and one tube in the front part was dry so I couldn’t squeeze it out with the caulking gun. I had to cut it open and pour it out that way and use a putty knife to smooth it into the cracks that I was filling in. So if you get a good tube, it works great. You need a large caulking gun. These are big tubesAs with anything like this time will tell if it seals to the cement and the asphalt and if it also takes to the paint that I will use for garage floor.

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.

El producto es justo lo que esperaba. Le doy cuatro estrellas debido a que llegó abollado de la parte inferior, pero funcionó correctamente.Ojo con las instrucciones, el tubo no entra en una pistola de silicón convencional, es necesario comprar una más grande.
