SIKA - Sealant - Sikaflex Concrete Fix - Limestone - Elastic sealant for Cracks and Joints - Paintable Polyurethane - 299 ml

I used a different product last year that was more like a gritty concrete in a tube that did not survive the winter- cracked and fell out. I knew on the first application that this was the real deal- it comes out thick, levels well with a putty knife and stays put, even when filling vertical cracks in my front patio. I used backing for the large crack in my shed concrete pad and this filled in well and looks great. When dry it feels like it will flex and make it thru the seasons.

Great stuff to fill in the cracks on my driveway. Easy to use and seems very durable.

Would give it 5 stars, but, it’s a little too thin. Needs to be just a bit thicker to stop sepping so far down into cracks. I just needed about 1/4 inch settling down in crack before it starts to set. Oh well some people need it just the way it is for deeper crack I guess.

works as advertised

I'm using this on some cracking on my pool deck. After following the instructions the repair went very well.

Seems to work well, but is ridiculously difficult to dispense.

What the Pros use

I hope I got a bad batch, 2 of the 8 containers burst at the seams and made a horrible mess, after I waited a few days for it to finally dry it still has a really cheap feel and appearance when you walk over it. Not impressed, waiting for the rain and heat to peel it up so I can start over with another brand.
