I don't know how long they say it will drip for but yes it will drip FAR longer then 2 days. More like 2-3 weeks.
In fact, I will get a few drips during the summer, and that is 8 months after I applied Krown. Thats good!
Furthermore, it does no damage to pavement and given time, you won't even see any hint of the product. The front of my street where I spray Krown on my own vehicles looks like a war zone prior to the snow flying. The following spring...hardly a trace.
Damaged? I doubt it. Poorly applying the product, certainly possible.
The good thing is it hardly matters as the product creeps so well. Another product that does not drip, now missing areas of application would matter...a lot.
I do my own Krown application. No holes, very thorough, but I know thats not a job most would undertake.
