Just got to the stamped concrete phase of our build and ran across an issue. The concrete crew started pouring around noon and got 75% of the concrete in and stamped with the first truckload. The 2nd batch was supposed to show up at 3:30pm. Well, it did not come to almost 6pm and the guys were obviously upset with the material guy. They poured and waited for it to cure to the same level as the first batch before stamping. It then started to rain lighly (unexpected) and they were out there until dark. 2 days later is see this:
I called the concrete guy and he assured me it will not be an issue as soon as they powerwash and seal. They use a tinted sealer to bring out the true color. Should I be concerned? Short term, long term?
