CUSTOMER REVIEWS

Rated 4.6 out of 5 by 21 reviewers.
Rated 4 out of 5 by fixed my crack I had a big nasty crack in my concrete driveway, I used this product to fill the gap. The directions say to just put it down on the crack with a caulking gun and let it sit. It is self leveling. After the fact I kind wish I would have used a putty knife on it to level it out. It kind has a little pump where the crack was. Look at my pictures and you can see what I am talking about. It seems durable though, and I don't expect it to fall off or anything. All I did for prep was sweep the cracked part of the driveway with a broom. September 25, 2013
Rated 5 out of 5 by Best In Class - Have Used Sika for 5 Years I've been using this product for over 5 years to seal driveway cracks and it dispenses and holds up much better than 2 similar products I have tried. The competing products are harder to pump out of their cartridges (which is important if you are using a lot of tubes) and they do not have the flexibility and long-term elasticity of the Sika sealant. Be sure when you use this that you first fill the crack with a pre-filler (my favorite is limestone base because it compacts) else you'll waste the sealant down the crevice of the crack, which is expensive. Also, if you live in a cold climate, never let the sealant fill above the level of the concrete, else your snow shoveling equipment will snag it and pull it out. June 4, 2013
Rated 3 out of 5 by OK but tedious with caulk gun This product performs as advertised. My only complaint is using a caulk gun can make this job slower than it should be job. I used it for expansion joints and it was difficult to do a professional looking job because of the nature of using a caulk gun (unless you use one regularly). I went though 2 tubes of this product before I stumbled across another brand that comes in a 32 oz plastic container. You squeeze it out like wood glue. I simply found the 32 oz container much easier and quicker. It also leveled out quicker than what came in the caulk tube. You may be perfectly fine with using a caulk gun, but I preferred the plastic container with the resealable cap.. It was also much cheaper. March 30, 2014
Rated 5 out of 5 by concrete crack/joint caulk This stuff works to seal the gaps which allow water into your slab joints. Which freezes and buckles and cracks the concrete slab. If the crack is deep you'll need to put filler into the crack first. HD has special closed cell foam strips made for this in several sizes which cut with scissors easily to stuff into those cracks so you only fill an area about 1/2x1" to conserve the sealer. I use a wood paint stirrer stick to stuff the crack. This stuff stays runny(self-leveling)for several hours. It will keep disapearing down that gap unless its partially filled first. It may take a couple of days to cure to its tough rubbery texture. You must cover it up with something to avoid walking on or driving over during full cure. I found that wide painters tape worked for me. This is difficult to get off your hands and everything it touches. Be neat and careful, wear gloves. Suitable solvents are pretty harsh on skin like xylene, acetone, fingernail polish remover, etc. Soap and water doesn't do to much. Once cured this stuff is stuck to whatever it's on about as tough as tire rubber. It's elastic and will move with the crack to a limited extent. I had an area of several inches let loose on one side. I cut out as much as I could with a box cutter and filled it back up with the Sikaflex. A very effective product which works. Comes in small 10.1oz caulk tubes and mega 29oz tubes. April 29, 2013
Rated 4 out of 5 by Sika seals shallow sidewalk splits Sikaflex flexible sealant is a cinch to use, and provides a nice, durable repair to those smaller cracks that develop in your sidewalk or driveway. I also like that the sealant, once cured, remains flexible, allowing for continued seal, even with seasonal movement of the concrete. A word of caution, however-- Sikaflex does work on cracks up to 1" wide, but only up to 1/2" deep-- a very small window of usability, in my opinion. If the cracks being repaired are deeper than 1/2", then you'll have to find a different product.. For SMALL sidewalk and driveway repairs, I'd recommend this product. August 6, 2013
