Self-leveling concrete - My bonehead mistake

Self-leveling concrete - My bonehead mistake
This is leveling 101.. You don't use warm water to mix self-leveling underlayments. Well I set up the job for a second floor pour at a local hospital. The closest water was an outside water bib on first floor. I had my guys run the hose up the wall, across the roof and through an access door to a hallway that led to our area.

The work began and I noticed right away that the material didn't self heal like normal. I had a shortened flow time between pours to blend the joints. The material set up really fast in the sunlit areas. Not until the entire 100 bags were down did it dawn on me that the hose running across the roof was warming the water. Luckily the roof was white rubber, but the green hose still absorbed radiant heat.

The job turned out not as good as we normally do, and I felt terrible. I talked with the flooring sub and asked him to evaluate the underlayment and let me know what his guys have to do to make it right. This bonehead move will cost me some money, but worse than that is it hurts my reputation. Sad
