Each inspection shall be documented and at the end of the job, submitted to inspection Department.
Any defect, deviation detected during inspection shall be rectified to the full satisfaction of Inspection.
General Inspection Guidelines:
Check for:
The Paint Manufacturer Certification,Manufacturing date and Expiry date General health of the packing Correctness of specification Surface Cleanliness of the subject surface.Surrounding area to ensure non-contamination during or just after application Surface cleaning equipment and procedure with due consideration to safety Proper surfaces after preparation free from all loose particles Proper cleaning of nooks & corners and difficult to access location Application Proper time lag from surface preparation to application Proper mixing (for two pack system) Correct application tools, procedure and skill Uniformity of wet film thickness per coat Proper inter-coat time interval,Adequate post drying hardness.
