## Description

desertcart.com: Sikaflex Self Leveling Polyurethane Sealant, Gray | Accelerated Curing | For Concrete Joints | Horizontal Application | 10.1 fl oz (4-Pack) : Industrial & Scientific

Review: Great product for sealing concrete gaps! - 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.
Review: Great product - 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.

## Questions & Answers

**Q: Will this work in joints in a sloped driveway?  I have long expansion joints running parallel to the slope, but it's not super steep.**
A: I like the other answers, and read them before I did my project. My driveway has about a 5-10% grade, with perpendicular and parallel joints, 1" width. I used 1.25" backer rod from an Amazon seller, but I bought the Sika sealant locally so I could return the excess. My fill was 0.25" The perpendicular joints were no problem. I made a couple of passes once it was clear that they wouldn't flow over. The flow along the parallel joint was so slow that it never sagged significantly. I had to add a small amount at the top a couple of hours later.  I used  a heat gun in the beginning, thinking that it would speed the set. Wrong. Low heat actually softens the sealant. 

But the heat gun was helpful in bringing bubbles to the surface and making them pop. Rough or irregular spots responded well to the lowest heat (Wagner Furno 500).

**Q: It says this product is paintable but it does not say that anywhere on the tube. Has anyone painted it with long term success?**
A: I have never seen this product painted.  It is a self-leveling caulk for wide joints in concrete primarily.  Used around pools and in expansion joints.  I always allow it to start to set then cover the surface with fine washed sand (no dust).  This gives it a better appearance and extends the life years beyond what it would be without some UV protection.  It should be used in a fairly thin application either with foam joint material or sand below it.  Typically it is only 1/4 to 1/2" thick.

**Q: In roadway, how long before heavy traffic can cross without damage to the caulking?**
A: I put this on my concrete drive and now for 2 years I have not had any problem. Great stuff

**Q: Will this stick to plastics such as vinyl?**
A: It should

### ⭐⭐⭐⭐⭐ The Ultimate Concrete Sealant—Effortless, Durable, and Professional-Grade
*by E***G on July 3, 2025*

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.
