Preparation can include cleaning, repairs, treatment of details, and other system-specific work. The required steps depend on the substrate and coating instructions. A quote that lists only coating area leaves the most important assumptions unclear.
What to do next
Ask for separate descriptions of preparation, repairs, and application. Confirm how unsuitable areas will be identified and handled. Compare bidders using the same existing-condition information so a lower price is not simply the result of omitted preparation.
