Stamped Concrete Release
Yesterday I had a stamped concrete walkway installed at my home. The contractor used a hand-scattered grey powdered release on the surface of the concrete. This morning when I went out to check things out, I noticed that my two new Resin Adirondack chairs on the front porch received a light dusting and although I scrubbed at them, they seem to now be slightly stained. I feel like an idiot for not moving them to a different area during the process but it did not cross my mind. They are brand new and rather costly so I am kind of sick about this.
The concrete team will be back today; I was just looking for some outside perspective...was this my fault or are they partially responsible? How would others handle it?
On a another note it rained last night and I hope this won't adversely affect my new concrete!
I apologize if this is too off topic for this forum. I wasn't sure where to turn for advice.
