>>The question has to be asked how many of the countless botched projects,
new construction and HP, that we all run across all the time, got to that
sorry state because of the incompetence or negligence of craftspeople?

Some unverified statistics we've heard:
Percentage of slab-on-grade flooring installations that fail: 25%
Percentage of coating failures attributed to poor surface preparation: 85%
Percentage of coating failures attributed to improper proportioning,
mixing, application, application conditions: 10%
Percentage of coating failures due to product defects: <1%

Do these sound realistic?
To this list, we would be inclined to add a category for failure to solve
underlying causes of deterioration, but could not accurately estimate a
percentage.
