Got this product to recaulk expansion joints that were felt material that had fallen apart. Cleaned out the old stuff. Followed the directions to apply only 1/2 deep and started to caulk. This was a tough job since I knew it was non-self leveling, but did not know it would flow like cold molasses. Had to be more of an artist to get a smooth looking job without touching the product with anything but the caulk tube nozzle. Anything else stuck in this material would create a mess. I would do it again - and use the same material. Works well and has nice battleship grey color.
