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

Great product. Used it for concrete joints for sidewalks and between driveway and garage. Make sure to use good painters tape and pressing the tape firmly in so that the self-leveling doesn't spill over your unintended area of concrete like I did. Also no to put back a rod and underneath the back of rod as necessary put sand so that you don't end up using too much of the sealant. I ended up using all 12 sealants for a three car garage scene and roughly 10 concrete sidewalks that are 4 to 5 ft and width. Very glad I have bought in bulk packaging as I was expecting some leftovers but ended up using all of them. Also make sure to let it dry 24 hours and also for the tape that are used to prevent spillage to remove those tape before the sealant fully cures. I peeled off the tape roughly around 6 to 8 hour of cure. I also test tried it on concrete cracks not sure how this will turn out but at least for now other than the aesthetic side it's a good piece of mind to know cracks are sealed to prevent further erosion beneath the cracks.

This works very well. However, there are some lessons I have learned. I will list them so they might help someone else. 1. Any deep cracks should be filled completely using backer rod or something else; otherwise the product will simply drain into the crack. 2. Wind mixed with leaves is not your friend. The leaves will fall into the product and you will have to wait until it dries to pull out what you can and the ones you can't get out will just have to decompose. 3. Have a piece of cardboard and a rag or paper towels nearby. It can get messy when you finish the section you are working on. The product will not completely stop flowing (slow stringy drip). 4. Start on a spot that is not too conspicuous. The first try will have some mistakes. After 2 or 3 times at using this, you will get really good at it. If you follow my lessons learned you might be good after your first try. Note: it takes about 2 days to dry to the touch. Hope this helps.

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.

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.

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 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..

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.

It got shipped from US to Australia in 2 weeks. Fills in the gap and self levels. It more fluid than expected.
