Review: I like this - Bought this for my pool area. It did not cover the area I expected but it did a good job and I bought it again to complete the job. I believe Coverage are is exaggerated but the sealant is great, dries quicker than others I have used. Hope it lasts as long as the others I have used, Dry time has generally had a direct impact on longevity in the past, hoping that changed
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.

## 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

### ⭐⭐⭐⭐⭐ Easy to apply
*by G***K on May 2, 2025*

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.
