Good product. Easy to use. However, the product is very thick so it was tough getting it out with a regular caulk gun. I hurt my palm so badly from squeezing a regular caulk gun so hard that I had to put my project on hold and let my hands heal for a week before finishing the project. I then found on Home Depot that there is the JES "high-thrust" (26:1 ratio) Caulk Gun that you can order online that makes the job 10x easier!!! It's night and day if you use the high thrust caulk gun vs a regular caulk gun. However, the high thrust caulk gun is only sold online so order the item ahead of time before starting the project. It's expensive though but it's worth it if you don't have the grip strength of Superman and don't want to permanently damage your hands. JES Caulk Gun (Model # M26S) https://www.homedepot.com/p/JES-10-oz-26-1-High-Thrust-Caulk-Gun-M26S/305860778 The results turned out pretty well (see photos). First, I took the time to properly grout out the cracks with either a chisel or a diamond grinder to make sure it was at least 1/4" wide and deep to absorb adequate product, used a wire brush to clean out all the crud (soil, moss, etc) in the cracks and then used a shop vac to clean out all the debris. For larger cracks, I used foam backer rod to fill it in to minimize the use of a lot of Silkflex since the stuff is a bit expensive. For a final finish after application, I sprinkled "local" sand (from the beach) on top of the sealant to match the concrete color and texture. If you use local sand, make it is dried first in the sun and had no debris in it. I used a kitchen shifter to remove debris in the sand. I covered the area with tarp so that the sealant could cure slowly and be kept dry for next 3 days. Tip: a) Use a "High Thrust" caulk gun like a 26:1 ratio instead of a regular caulk gun b) Take the time to prep the crack properly before application to make sure there is adequate sealant to be absorbed and adhere properly to a clean crack. c) Top the finish work with local sand to match color and texture d) Make sure to check expiration date on the bottom of each tube!!! It make a huge difference how it flows out of the tube. I used a tube that was within 3 months of expiration and it was a bit challenging getting it out vs. a tube that was 1 year from expiration and it seem to flow a lot easier.

                  Does a good job of filling the concrete cracks. Takes a while to sink in so you have to do multiple coats or it still looks like a crack. Color did not match older concrete but I did not expect it to do so. Could have used mortar mix but this was less abrasive to work with and I just wanted to try it.
