I used it to fill cracks in concrete. Use it only on perfectly flat surfaces. On surfaces that are not 100% flat, the epoxy will run off into unintended areas, and these unintended areas of coverage will be very hard to clean. This epoxy will tend to dry to a super-hard compound, which is great if it's applied in the right places, but really difficult to remove if it's not. Compared to paste-based epoxies that I have tried (for sloping surfaces), I found this epoxy to dry to a harder substance. I also found that, when applied to concrete cracks, I might have to apply more compound the following day because shrinkage had occurred overnight, or the material has been absorbed into the concrete.
Excellent for flat surfaces.

From the manufacturer
Surfaces must be clean, sound and preferably dry, but must be free of standing water. Sikadur Crack Fix may be injected into cracks, used to anchor bolts and dowels in horizontal surfaces and to seal slabs.
Remove twist-cap and port plug from the top of the cartridge. Press one of the ‘flow restrictors’ into the opening. Insert a static mixing nozzle (as supplied) through the twist cap and attach to the threaded section. Insert the Sikadur Crack Fix cartridge into a good quality caulking gun.
Inject Sikadur Crack Fix with slow, steady pressure.
Remove excess material to prevent a surface film forming.

Clear epoxy resin works best for hairline crack size.
It came with 2 sets of attachments and a resealable cap. 180ml doesn’t sound like a lot but it’s enough to seal two 5 feet long cracks on concrete. Very strong chemical smell, wear a mask and use only in a well ventilated area. I tested it on a garage concrete pad. The crack is about ⅛-¼ wide. It was very running like clear syrup. Works really well for filling the crack and self leveling. Take your time and refill the crack if needed. A bit sticky on touch after half an hour. Feels solid overnight and will be fully cured after 7-14 days. No water can go through the crack anymore, and a smooth surface will not trap any dirt or salt. This product is designed for use on well leveled surfaces. Works best for hairline crack size. It’s a bit pricey but hopefully this is the permanent solution instead of redoing it every spring.
