Architects, Engineers, Property Owners, and Other Important People: Job Planning

Most job specifications for surface preparation state the surface should be "sound, free from surface defects dry, and clean." Each of these terms is subjective, so it is important that the job specifications, the coatings or overlay specifications, and the expectations of the architect and/ or project engineer are in alignment.

Specifications should also say how uniform, clean, rough, and what strength the concrete substrate should be prior to a coating or overlay installation. See "Standards You Should Know About"

Proposals for surface preparation specifications should clearly spell out cleaning methods, profiling method, and surface defect repair procedures.

Other specifications may include time schedules and acceptable levels of noise and dust. Also, is there time in the schedule for concrete to dry to the required moisture level if water is being used in the cleaning process? If the specifications dont cover these issues- make sure they get covered.
