Sikaflex Crack Flex Sealant, Gray, High-Performance Textured Polyurethane, Self-Leveling, Waterproof Sealant for Horizontal Cracks Up to 1 in Wide, 10.1 fl oz,

The gray water tank on my class A RV was smelling terrible. It was getting inside the living area and making everything smell terrible. I couldn’t find a leak anywhere. When I looked at all the connections and the tank, the only thing I could find was how this pipe went into the top of the tank, there was no rubber connection with clamps. That seemed very suspicious to me. It just appeared to be stuck into the top of the tank, and sealed in there with what appeared to be plumbers putty. I called the manufacturer and asked if this was how it was supposed to be. I would purchase a rubber connection if it was available. They said they are still doing it this way and if they have a problem to use a Sikaflex gray compound. I purchased a tube, and although the pipe comes out of the top of the tank I used the self leveling compound. I started applying it above the suspect area and let it flow down over the existing stuff and let it flow onto the top of the tank. It actually made a very nice looking cone shaped seal. By that evening, I could tell the smell was getting better. It’s been about two weeks and you can’t detect it in the RV anymore. I have aired out the basement in the RV and that seems fine now too. I would highly recommend this flexible sealant. It’s amazing how flexible it is and how well it sealed this connection. We suffered with the smell for years until I had checked every fitting and the tank. The only thing left was this connection, but it appeared fine. The crack filling abilities of this self leveling system must have flowed into the source of the problem! Best ten bucks I’ve spent in a long time!

This stuff is amazing and absolutely delivers on it's promises! I originally completed this project using the horrible Dap version of concrete filler/seal which was horrible to work with and NEVER set (even after 2 dry 70 degree days) and essentially washed away on 1st rain. I completed the project again with this Sikaflex and it worked perfectly. It completely self levels and fills in the void. The best advice I have is DON'T touch it. Just lay your bead and let it work it's magic. It completely levels and leaves a smooth finish. Then come back and re-fill any voids that may appear. I had used sand then backer rod so I only had one corner spot that needed a little extra fill. I also sprinkle a little of the sand on the still wet seal to add to the concrete look though this Sikaflex already has a nice texture. This stuff has a great look on it's own and I'm so impressed with how well it works and looks. It's now cured and firm, yet pliable to the touch. I should have used this stuff in the first place.

OK, it's sika and it's a great sealant. I've used this to seal some cracks along my concrete patio. When i see self-levelling i am typically expecting it to be a little viscous, but able to really seep down into the cracks while also providing a smooth, level finish. I understand if you use too much, it's going to pool, but this is just really too viscous to provide a good level finish. Maybe it's user error, but i feel i did the best i could with the product. Maybe i have the wrong product for this application. Regardless, i feel it needs to be a little less viscous than it is.

I have a gap about 1" wide between my garage apron and the concrete slab adjacent to it. It looked like it had been filled with something black, maybe tar and it broke up when I ran compressed air over it to clean it up. Certainly not flexible material at this point and already had cracks in it. I had read about this type of "self-leveling" product (which has been used elsewhere in my neighborhood) and decided to give it a try. Although I had some backing, I wasn't calculate how much I would need, so I started with 3 tubes. That got me about 2/3 of the way across the apron - a little better than expected. Not bad for a 1" gap. (Also the slab is tipped 1/2" - 3/4" relative to the apron across it's width so that the edges cross in the middle; water will have to follow the gap ~ halfway to flow onto the slab.) I went to order a couple tubes to finish and in a couple of weeks the price had doubled from $10/tube. Turns out the local Home Depot carries it for around $10. I hadn't worked with this self-leveling product before and it really does flow even more easily than I expected which means your prep has to be pretty good. Although it says it can be "tooled", I had minimal success with that (after 20-30 minutes) - maybe if you work it immediately. I found I had to lay a little less than I thought was needed and go back over it a few minutes to get the level I wanted. There is a little "knack" to using it well, but I got it after using 3 tubes, One thing I did find which is illustarted in the image, when I went back a day later to continue filling the gap, the new material didn't quite blend seamlessly with the day-old material. (See red arrow, and dashed line which traces part of the "seam".) The image exagerates it a bit, but as a perfectionist I notice it. The difefference in height is like 1/16" ... not much frankly. Overall it looks real good to me given the alignment issues. Been in place a few weeks. Interested to see how it fairs over the Western Pennsylvania Winter.

I called and spoke with a Sika rep to make sure I was using the correct product. I have used their products in the past and have been very happy with the results years later. This crack fix is no exception to that! This product is self leveling, so you would only use it on a horizontal surface. I prepped the crack by using my Ryobi multi tool with diamond blades that I purchased on amazon to widen the crack. I then brushed everything out with a wire brush and then blew out the area with a blower, as the multi tool caused a lot of dust. This was still a lot easier, cleaner and safer than chiseling the crack wider. Filled the crack with this Sika product and it turned out really nice and clean looking. I used another Sika product to fill my garage floor expansion joints after the garage was built, the garage is in it's 7th year and the Sika product is still going strong! Highly recommended!

Good product although a little expensive for the application

solo que no hay manera de ver la caducidad del producto, lo mandan muy limitado

This product is excellent for small home repairs. I used the SIKA Premium Grade Polyurethane Sikaflex to fix the area around my bathroom tap, and it worked really well. It adheres firmly to surfaces and creates a strong, waterproof seal that gives confidence it will last. The application was smooth and easy to control, and it stayed in place while curing. Once set, the sealant feels solid and durable. It also resists moisture well, which is perfect for bathroom use. Overall, this is a high-quality sealant that does exactly what it promises. It made my repair easy and reliable, and I would definitely use it again for similar projects.
