If you’re looking for a sealant that combines ease of use with long-lasting performance, look no further than Sika Sikaflex Self-Leveling Sealant. This product has transformed my concrete surfaces, providing a clean, durable, and professional finish with minimal effort.Why I Love It:• Self-Leveling Magic: The true beauty of this sealant lies in its self-leveling properties. Once applied, it flows smoothly into joints, creating a flat, even surface without the need for tooling. This feature is particularly beneficial for those new to sealant applications, as it reduces the chances of uneven lines or missed spots.• Durability That Lasts: After curing, the sealant remains permanently elastic, effectively bridging gaps up to 1.5 inches wide. It’s designed to withstand the rigors of daily traffic, weather fluctuations, and the wear and tear typical of high-traffic areas like driveways and garage floors.• Quick and Easy Application: The product is a one-component polyurethane sealant, meaning no mixing is required. It’s available in both 10.1 fl. oz. and 29 fl. oz. cartridges, catering to various project sizes. The application process is straightforward—just clean the joint, apply the sealant, and let it level itself.• Paintable and Weather-Resistant: Once cured, the sealant is paintable with water-based, oil-based, or rubber-based paints, allowing it to blend seamlessly with your existing surfaces. It’s also waterproof and resistant to aging and weathering, ensuring long-term performance.Tips for Best Results:• Surface Preparation: Ensure that the joint surfaces are clean, dry, and free from oil, grease, or any other contaminants. This will promote optimal adhesion and longevity of the sealant.• Use Backer Rods: For deep joints, consider using a backer rod to control the depth of the sealant and prevent excessive use.• Curing Time: Allow the sealant to cure for 3 to 5 days for full strength. During this period, avoid any traffic or disturbance to ensure the best results.

I bought this to seal up the expansion cuts in the garage concrete. I noticed a while ago that the expansion cuts had done their job and there were cracks in the bottom of each cut, probably going down through the whole slab. I've got some radon issues here so i wanted to get something I could apply that would drip down and flow well enough to get a reasonably air tight seal in the cracks.I had to use quite a lot of the sealant but it did flow from the top of the cuts down to the bottom (the cut was too narrow to get even the smallest part of the tip inside it). The cracks are narrow enough that it didn't flow down the crack itself. I would not bet on that always working because this stuff is very runny and can easily flow down a crack. Fortunately the cracks at the bottom of my expansion joints are very small.It cleans up well off the sealed concrete in my garage. I'd hate to think about cleaning this off rough outside concrete. It's definitely not cheap but it's the kind of thing I want to only have to do once so a quality polyurethane seems like a good choice given that I may eventually paint the garage floor. For outdoor applications, where there's no chance I'll paint it, I may opt for silicone based because it resists UV better.

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.

This self leveling caulk is excellent. I used it in the basement between concrete walls and concrete floor. It flows beautifully, looks great and is wonderfully effective.

That amazon does not this item without damage. The product is good, i think... i wont know for a couple of years so all i know is that it is easy to use.and definitely looks better than the crack. But amazon doesnt protect the spout of this product from damage, and half of those i have ordered arrive with broken and bent spouts. The box the cartridge is shipped in is too big and the cartridge is allowed to shift and break its spout... which has a weaker support than 10oz cartridges

This works exactly as it should. It's nearly liquid (and will drip out once the seal's busted and the canister is tilted) and self-levels well. Not appropriate for vertical surfaces; it won't hold a bead.
