    Before Painting

    Preparation of painting specification involves understanding environmental factors, location of piping (indoor or outdoor), insulation requirements, operating and design temperatures. It may also involve local rules and regulations as well as availability of materials.

     

    Painting Workflow

    - Ensure all tests are performed on piping system before starting painting work.

    - Clean painting surface to remove oils, grease, dirt.

    - Ensure proper room temperature and humidity levels.

    - Use hand tools, machine tools, shot blasters etc to clean surface as per relevant standards and project requirements.

    - Apply primer within 4 hours of surface preparation.

    - Apply paint coats after previous coats have dried up, as per instructions of paint manufacturer.
