Sikaflex Self Leveling Polyurethane Sealant, Gray | Accelerated Curing | For Concrete Joints | Horizontal Application | 10.1 fl oz (4-Pack)

This stuff works exactly as described. It fill the gaps easily, self levels and dries to a nice level, rubbery texture. It dries light grey and looks very nice. No more weeds or dirt accumulating in the cracks of the concrete.

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

this stuff works perfect every time. it's fluid enough to flow into the cracks and pools and levels perfectly. Excellent, durable, and the standard for self levelling sealant for pool coping/decking.

Great product, seals gaps in concrete well and seems durable. Take caution not to cut tube end opening to large as sealant will continue to run out of tube even after releasing the chalking gun handle.

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.

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.

Worked great for sealing gaps and cracks in garage. Would recommend using the foam backer rods to save on how much sealant you need to use

I am very disappointed with this Pro Select Silca self-leveling sealant. I just opened the tube for the first time, cut the tip, and attempted to use it, but nothing would come out. The sealant appears to be dried up or hardened inside the tube, making the product completely unusable right out of the package. This was my first time using the product, so it was not due to improper storage or an old, previously opened tube. Unfortunately, I discovered the issue only when I was ready to start my project, which caused unnecessary delays and frustration. Based on my experience, I cannot recommend this product due to the quality issue I encountered. I expected a usable sealant, but instead received what appears to be a dried-out tube.

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.
