Cement/concrete is the hardest material to remove pet urine or any odor since it is so porous. The good news is there is a remedy.
You have two options.
Option 1, follow the instruction steps which requires equipment and several water application steps. Odor bloom is common with porous surfaces. Odor bloom is a chemical process where dried urine crystals are rehydrated and bring up a pungent smell. It tells you the removal process is only half done. Odor bloom occurs most with deep, old, set-in urine spots and is likely to occur with cement. Odor bloom is unlikely to occur with new, surface urine spots. If you have deep, old, set-in urine spots you should choose a kit for the best results.
