Best stuff you can buy
I was unbelievably picky in selecting this product. This product did everything I needed it too. Pretty easy to apply and filled the cracks nicely. I used a utility knife blade while the product was still uncured to level it. Virtually no smell and hardened nicely.

Product may work but not worth effort
The product was okay, it hardens nicely and looks okay but it was nearly impossible to get the product out of the caulking gun. It was way too much effort.

Filling Workshop Floor Cracks
After being irritated for years by a long thin hairline crack in my workshop floor, I decided to do something about because I eventually plan on painting over it with an epoxy floor paint. This product had a fairly thin consistency that made it easy to fill the crack without making a mess or wasting too much product. The crack is completely filled now, and you won’t even know it’s there once it get painted over

Did not like the end result
It is easy enough to use, goes in a standard caulk gun to dispense. It is a 2 part epoxy that mixes in the tube spout. You get 2 spouts as they are not resuable. When cured (dry) you have a very glossy/shiny sheen over the applied surface. It is supposed to be "buff" colored, its not, it cures to a milky white and very shinny. Does not blend in with the concrete surface.

Really Works
Filled driveway cracks in asphalt. Looks good and holds together.

I think the tubes were old and beyond useful shelf life
I was disappointed in the quality of the 3 tubes I purchased. The 1st tube only pumped the clear, watery substance. The 2nd and 3rd tubes only pumped the thicker substance, which was extremely difficult to pump, even with a 8:1 gun as recommended. These tubes took an extra-long time to cure, remaining tacky for weeks and thus collecting dirt and grime before drying fully. My belief is that the tubes I received were old and beyond their useful application date.
