Cleaning may reveal conditions that were hidden by debris or surface contamination. A decision to coat should follow an assessment of suitability rather than automatically follow cleaning. The two services have different objectives.
What to do next
Ask for findings after preparation and before full application where the project sequence permits. Clarify what discoveries could change the scope. Keep the owner's approval process explicit so newly visible damage is evaluated instead of covered to preserve the original schedule.
