1.03 DEFINITIONS
A. Definitions used in this Section are in accordance with definitions referenced in ASTM D16, ASTM D3960, and SSPC Glossary of Definitions.

B. Specific definitions:

1. Abrasive: Material used for blast cleaning, such as sand, grit, or shot.

2. Abrasive Blast Cleaning: Cleaning/surface preparation by abrasive propelled at high speed.

3. Anchor Pattern: Profile or texture of prepared surface(s).

4. Biogenic Sulfide Corrosion: Corrosion caused by sulfuric acid formed when Thiobacillus bacteria metabolizes hydrogen sulfide.

5. Bug Holes: Small cavities resulting when air bubbles are entrapped in the surface of formed concrete during placement and consolidation.

6. System: Protective film with 1 or more coats applied in a predetermined order, including surface preparation and quality control requirements.

7. Coating/Paint/Lining Thickness: Total thickness of primer, intermediate, and/or finish coats after drying or curing.

8. Dew point: Temperature a given air/water vapor mixture starts to condense.

9. Drying Time: Time interval between application and material curing.

10. Dry to Recoat: Time interval between material application and its ability to receive the next coat.

11. Dry to Touch: Time interval between material application and its ability to tolerate a light ouch without coating damage.

12. Exposed Surface: Any indoor or outdoor surface not buried or encased.

13. Feather Edging: Reducing coating thickness at its edge to blend with existing surrounding coating.

14. Feathering: Tapering off a wet edge with a comparatively dry brush.

15. Ferrous: Cast iron, ductile iron, wrought iron, and all steel alloys except stainless steel.

16. Field Coat: Application of a surface coating system at the work site.

17. Finish Coat: Final coat in a paint system, including texture, color, smoothness of surface, and other properties affecting appearance.

18. Hold Point: A defined point, specified in this Section, at which work shall be halted for inspection.

19. Holiday: A discontinuity, skip, void, or pinhole in coating or coating system film that exposes the substrate.

20. Honeycomb: Segregated and porous surface of hardened concrete due to insufficient consolidation.

21. Hydroblast: High or ultra-high-pressure water jet surface preparation.

22. Incompatibility: One coating's inability to overlay another coating or surface as evidenced by bleeding, poor bonding, or lifting of old coating; inability of a coating to bond to a substrate.

23. Immersed/Immersion: A service condition in which substrate is submerged, is immediately above liquids, or is subject to frequent wetting, splashing, or washdown.

24. Laitance: A thin, weak, brittle layer of cement and aggregate fines on a concrete surface.

25. Mil: 0.001 inch.

26. Overspray: Dry spray, particularly paint bonded to an unintended surface.

27. Pinhole: A small diameter discontinuity in a coating or coating system film, created by offgassing from a void in a concrete or masonry substrate causing a void between coats or exposing the substrate. Usually caused by coating application while temperature is rising.

28. Pot Life: Time interval after components are mixed and coating can be satisfactorily applied.

29. Prime Coat: First full paint coat applied to a surface when using a multicoat system. Primers adhere to a new substrate, protect the substrate, and promote adhesion of subsequent coats of paint. The prime coat on metal surfaces is the first full coat and does not include solvent wash, grease emulsifiers, or other pretreatment applications.

30. Resurfacer/Resurfacing Material: A layer of cementitious and/or resin-based material used to fill or otherwise restore surface continuity to worn or damaged concrete surfaces.

31. Shelf Life: Maximum storage time a material may be stored without losing its usefulness.

32. Shop Coat: 1 or more coats applied in an off-site shop or plant before shipment to work site where field or finishing coat(s) are applied.

33. Spreading Rate: Area covered by a unit volume of paint at a specific thickness.

34. Stripe Coat: A separate brush coat of paint applied to all weld seams, pits, nuts/bolts/washers, and edges. This coat shall not be applied until previous coats have cured. Once applied, the coat shall be allowed to cure before subsequent coats are applied.

35. Tie Coat: An intermediate coat that bonds different types of paint material, improving succeeding coat adhesion.

36. Thick Film Coating System: A coating system applied with a minimum dry film thickness of 25 mils.

37. Touch-Up Painting: Application of paint on previously painted surfaces to repair marks, scratches, and deteriorated or damaged areas to restore the appearance and performance of the coating.

38. Water Blast: An alternative to air abrasive blast cleaning that can be used with or without abrasive injection. Water cleaning at pressures up to 5,000 pounds per square inch is called low-pressure water cleaning or power washing.

High-pressure water cleaning uses water pressures between 5,000 and 10,000 pounds per square inch. Water jetting is water blasting with added abrasive at pressures between 10,000 and 25,000 pounds per square inch.

Ultra-high-pressure water jetting is water blasting at pressures above 25,000 pounds per square inch.

39. Weld Splatter: Beads of non-structural weld metal that adhere to the surrounding surface, removed as part of surface preparation.
