Our coating consultants have decades of experience providing coating failure investigations, paint system recommendations, painting specification preparation and other professional services.

To obtain a proper finished coating job, it is essential that periodic inspections be made before, during, and following the application. Proper inspection procedure begins with an inspection of the prepared surface. The specification for the job and or the product data sheet (if there is no specification) spell out the required surface preparation, but making sure this is accomplished is often the job of the inspector.

Therefore, it is important that the inspector be familiar with the specifications, the product data sheets and the inspection tools necessary to perform the necessary checks.

However, just because there is a third-party inspector on a project, this does not relieve the contractor of their responsibility to perform in accordance with the specifications.

The contractor is responsible for their own quality control.

After the surface has been satisfactorily prepared in one of the manners described before, it should be thoroughly dusted or vacuumed if abrasives or other dust generating materials were used to perform the surface preparation.

Surfaces that do not meet the specification standards must be redone before any further steps are taken.

Each coat should be carefully inspected before the succeeding coat is applied. The inspector must ensure that sufficient drying time (i.e. minimum recoat window), as stated in the manufacturer’s product data sheet / application instructions, be allowed between successive coats.
