General Discussion

The contractors used the wrong materials for both the primer and the coating. They both lack the flexibility to handle the expansion and contraction caused by temperature changes. The effect of hydrogen peroxide has nothing to do with the primer separating from the top coat. The effect of h2o2 is merely to add oxygen. It wouldn't have much affect on the coating. Neither would driving over it after it was cured. The nano bubblers and h202 worked on blue green algae, but then green algae moved in and it's a lot tougher to control. It's amazing to me that most of the public seems to be clueless about how contracting works. Large coating jobs like nearly every aspect of contracting is based on manufacturers specifications not the contractors. In this botched job the manufacturer it seems no architects or material suppliers were involved. It's been a lot of time since I retired and I'm not up on current prices but Im thinking a price of around $40 per square is at least 3 times what it should be, but I don't have a spec for other work done beside the coating. This whole thing is a classic example of why we follow processes instead of trust contractors.
