Thanks all for the input. To answer "Italian" .....
The driveway was laid in 4 pours over the period of a week due to the
size of the overall job, and the window of opportunity for handling the
stamping. The release was left on for 7-10 days. To remove it, a high
pressure (water) washer was used. The weather conditions during the
entire period was warm & sunny - 80's during the day, 50's at night,
some clouds in the AM - typical California semi-coastal summer
pattern. No rain. The seal coat was applied approximately 1 week
after the end of the last pour. It was applied using a pump type
One other item of note is that the temperature on the days the peeling
occured was in the 90's, and the concrete was hotter still. I don't
know if the heat may have been responsible for some kind of
reaction/adhesion between the tire rubber and the seal coat.
The contractor who performed the work is experienced, has good
references and I've seen his work. He has also done work for us
before. It's not a situation where I want to threaten him as I want to
give him a chance to make this right, which I believe he will. I just
want to try to understand the possible technical possiblities, things
to try, possible mitigation, which you have provided. Thanks for the
input, and any other suggestions please post.
