Customer Reviews for Sika 10.1 fl. oz. Sikaflex Concrete Fix No-Sag Concrete Crack Filler Repair Polyurethane Sealant in Limestone

This sealant was used in a crack in a 50 year old cement block retaining wall. I noticed a crack in the corner tuck point joint. After cutting a 3/8" deep cut in the joint and cleaning it, I filled the void using the Sikaflex product and smoothed it out. Looks great, Great adhesion and flexibility.

Great product for sealing wall cracks.

Only complaint is that it is only available at Home Depot in the 10.1 oz. size. Needed 14 tubes for my project. Would have used the 29 oz. size if it were available.

I used 18 tubes of 10.1 fl. oz to repair concrete cracks in my driveway. It was a very easy process; time will tell how long it will last. I cannot provide 5 stars because I have no clue on the lasting power of the product.

Does a good job of sealing cracks in concrete.

Works great. Dries fast. Easy to set as well. What I'm actually waiting in is if the tube dries up completely before I am able to use it again. But thus far, no issues.

Good stuff, easy to use. Hopefully it will last.

This is a good product!! It filled the crack in our concrete wall and held well. I recommend this product for concrete cracks. It's good!

I had a divide between two points in my patio. This was able to fill that with ease. It was also very quickly drying which was nice to keep the job moving along. A little pricey but it did the job it was made to do. I would recommend this product to others.

This product sealed up some major leaks that I had in a pool fountain system and also my sidewalk. Would definitely recommend this product if you need some water tight sealing between concrete.

I bought this Concrete Fix because my old tube has expired, and I can't get it out of the tube. I used this in two long cracks of the sidewalk to stop the intense rain from running into the basement. It works.

This one has polymers added to cement base. They make patch less prone to cracks and flakes than original cement. Imagine if you would patch a crack with silicone caulk that had cement particles suspended in it. I had a stubborn crack in concrete garage floor ramp just outside of the gate that I had to patch it several times before and this blend killed it. It no longer re-appears.

Easy to use and strong

this stuff goes on easy, it sticks to the surface even on vertical and overhead surfaces. Performed just as I hoped

Worked as advertised and seems to be holding

Easy to apply. Dries rapidly. Easy to paint over it.

It was hard and must be old
