If anyone has been doing a sidewalk poetry project where you are stamping words into fresh concrete, I’d love to pick your brain about three technical issues:  the exact concrete specification you’re using (and that is working for you), the amount of time you are allowing for the poured concrete to set up before stamping, and the nature of the release agent you are using on the stamp form.  We’re doing testing for a project right now and nothing we are trying seems to work the way we need it to.

Thanks,
