Application with a tank bought in a hardware store. I first tested the smaller version of Hot Exit with integrated sprayer, last but not working well, the jet was bad. With a single spray at 10 euros (brand Central Park), the jet is perfect.
I abundantly sprayed 1 time per week. But sometimes I can only do this 1 time every 2 weeks, which is inadequate.
So I see that there is very little waste, it seems to work. But I think that 1 to week is a minimum to create habits in dogs and cats.
In addition it rains a lot in my area, so it does not help. But the product looks tough, especially on the stones, it makes darker. Test before to see how it reacts.
When applying it feels a little chili, but much less troublesome than other products I tested. The next day, it no longer feels anything, except perhaps very closely. Even animals feel. It is white slightly red, shake well before use.
Apply with gloves and goggles. It is not very aggressive, but a little anyway.
