1. Use the drying time between filler/surfacer and coating system specified by the CSM for the site conditions.
a. Let concrete substrate dry before applying filler/surfacers or coating system materials.

3. Apply a complete parge coat of the specified filler/surfacer material over the entire substrate before applying the coating system.
a. Scrub filler/surfacer into the substrate to completely fill open air voids and bug holes.
b. Completely cover the substrate, unless otherwise specified, above such filled voids by 1/8 inch of thickness.
c. Provide relatively flat, uniformly even surface before coating application.

4. Secondary containment: Place surfacer or filler 1/16 inch thick above concrete plane to create a monolithic surface free of pinholes.
a. Floor surfaces: Broadcast with aggregate to create a non-slip surface texture.
b. Remove excess aggregates and apply base coat to encapsulate embedded non-slip aggregate.

C. Concrete substrate temperatures:

1. Apply filler/surfacers and the coating system when temperatures are falling, typically late afternoon or evening.
a. Do not coat concrete with rising concrete substrate surface temperatures or substrates in direct sunlight, to minimize outgassing from the substrate and formation of pinholes, and/or blistering.

2. Should bubbles, pinholes, or other discontinuities form in the applied coating system material, they shall be repaired.
a. Should discontinuities develop in the filler/surfacer material or in the first coat of the coating material, repair them before the next coat. b. When discontinuities occur, open the air void behind or beneath the discontinuities and completely fill with specified coating material. Then, abrade the coated area around the discontinuities repair reapply coating over that area.

D. Perform application detail work in accordance with these Specifications, the CSM’s current written recommendations, and drawings, whichever is stricter.

E. Concrete coating systems application requirements:

1. Concrete coating minimum dry film thickness excludes parge coat, block filler, and sealer.

3.13 QUALITY CONTROL
A. Owner-provided inspection or inspection by others does not limit the Contractor’s or CSA’s responsibilities for quality workmanship or quality control as specified or as required by the CSM’s instructions. Owner inspection is in addition to any inspection required of the Contractor.

B. Owner may perform, or contract with an inspection agency to perform, quality control inspection and testing of the coating work covered by this Section. These inspections may include the following:

1. Inspect materials upon receipt to ensure that the CSM supplied them.

2. Verify that specified storage conditions for the coating system materials, solvents, and abrasives are provided.

3. Inspect and record findings for substrate cleanliness.

4. Inspect and record pH of concrete and metal substrates.

5. Inspect and record substrate profile (anchor pattern).

6. Measure and record ambient air and substrate temperature.

7. Measure and record relative humidity.

8. Check for substrate moisture in concrete.

9. Verify that mixing of coating system materials is in accordance with CSM’s instructions.

10. Inspect, confirm, and record that coating system materials' "pot life" is not exceeded during installation. Inspect to verify that recoat limitations for coating materials are not exceeded.

11. Perform adhesion testing.

12. Measure and record the coating system's thickness.

13. Verify proper curing of the coating system in accordance with the CSM's instructions.

14. Holiday or continuity testing in accordance with NACE SP0188 for coatings that will be immersed or exposed to aggressively corrosive conditions.

C. Contractor shall perform holiday testing in accordance with NACE SP0188 to identify holidays or pinholes needing repair for coating over 100 percent of surfaces:

1. Coated steel that will be immersed or exposed to aggressively corrosive conditions.

3.14 CORRECTIVE MEASURES
A. Repair pinholes or holidays identified by Holiday Testing as follows:

1. Remove the coating system with a grinder or other suitable power tool.

2. Remove coating system at all pinholes and holidays at least 2 inches diameter around the defect back to expose substrate.

3. Concrete voids: chip back to expose entire cavity in all directions. a. Completely fill void with approved filler/surfacer material using a putty knife or other suitable tool and strike off. Cure per CSM’s recommendations.

4. Aggressively abrade or sand the intact coating system surface at least 3 inches beyond the removal area in all directions to produce a uniform 6- to 8-mil profile in the intact coating system.

5. Vacuum the prepared area to remove all dust, dirt, etc., leaving clean, sound surfaces.

6. Tape to mask the periphery of the prepared intact coating area to prevent coating repair application onto the prepared area.

7. Apply the coating system with enough coats to achieve the specified finish coat thickness over the defect and coating removal area. Feather the coating onto the abraded coated surfaces around the removal area to avoid a lip and to achieve a neat repair outline.

8. Follow curing time between coats as specified by CSM for the site conditions.

Solvent wash and abrasive blast per CSM's instructions, if the maximum recoat time is exceeded.

9. Apply coating at specified dry film thickness.

3.15 CLEANUP
A. Remove surplus materials, protective coverings, and accumulated rubbish after completing coating. Thoroughly clean surfaces and repair overspray or other coating-related damage.

3.16 FINAL INSPECTION
