As I remember, Bob, it was sold as a pet pad originally. Some of the retailers also claimed there was an enzyme in the pad that digested urine and didn't allow it to penetrate to the sub floor.
I will say it does work well for the pet purpose. The only downside is the pad causes the spot to spread wider. If you know they have that pad(most who purchased it will tell you) be sure to move 6" to a foot out and treat the outer area too.
PS.
I agree its pretty worthless other than its original intended use. But retailers and manufacturers will make claims/market their products for applications that just aren't very practical
