PART 3 EXECUTION 3.01 EXAMINATION A. With Applicator present, examine substrates and conditions under which high-performance

coatings will be applied, for compliance with coating application requirements. 1. Apply coatings only after unsatisfactory conditions have been corrected and surfaces to

receive coatings are thoroughly dry. 2. Start of application is construed as Applicator’s acceptance of surfaces within that

particular area. B. Coordination of Work: Review other Sections in which primers or other coatings are provided

to ensure compatibility of total systems for various substrates. See Structural Steel sections for primer application to Exterior Architecturally Exposed Structural Steel. 1. Spot test an area which has been primed by others in order to determine if paint lifting will

occur. If paint lifting occurs, notify Architect and remove existing paint using SSPC-SP6 “Commercial Blast Cleaning” surface preparation at no additional cost. As an option to Commercial Blast Cleaning, and upon approval by the Architect, the Architect may select a Barrier Coating in addition to the specified primer at no additional cost.

2. If incompatibility of primers applied by others exists, obtain confirmation of the existing primer’s ability to be top coated with materials specified.

3.02 PREPARATION A. General: Remove plates, machined surfaces, and similar items already in place that are not to

be coated. If removal is impractical or impossible because of size or weight of item, provide surface-applied protection before surface preparation and coating. 1. After completing coating operations, reinstall items that were removed; use workers skilled

in the trades involved. B. Cleaning: Before applying coatings, clean substrates of substances that could impair bond of

coatings. Remove oil and grease before cleaning. C. Ferrous Metal Substrates: See “Coordination of Work” above.

1. Clean ungalvanized ferrous-metal surfaces that have not been shop coated; remove oil, grease, dirt, loose mill scale, and other foreign substances. Use solvent or mechanical cleaning methods that comply with SSPC recommendations.

CDH-13072 Addendum No. 4

09 9600-3

2. Treat bare and sandblasted or pickled clean metal with a metal treatment wash coat before priming.

3. Touch up bare areas and shop-applied prime coats that have been damaged. Wire brush, solvent clean, and touch up with same primer as the shop coat.

D. Material Preparation: Carefully mix and prepare coating materials according to manufacturer’s written instructions. 1. Maintain containers used in mixing and applying coatings in a clean condition, free of

foreign materials and residue. 2. Stir materials before applying to produce a mixture of uniform density. Stir as required

during application. Do not stir surface film into the material. Remove film and, if necessary, strain coating material before using.

3. Use only the type of thinners approved by manufacturer and only within recommended limits.

E. Tinting: Tint each undercoat a lighter shade to facilitate identification of each coat where multiple coats of the same material are to be applied.

3.03 APPLICATION A. General: Apply coatings according to manufacturer’s written instructions.

1. Use applicators and techniques best suited for the material being applied. 2. Do not apply coatings over dirt, rust, scale, grease, moisture, scuffed surfaces, or

conditions detrimental to forming a durable coating film. 3. Prime Coats: Before applying finish coats, apply a prime coat of material, as

recommended by manufacturer, to material required to be coated or finished that has not been prime coated by others.

4. Coat all surfaces, even though not visible, in order to provide protection from rust or corrosion. a) Coat surfaces behind movable equipment and furniture the same as similar exposed

surfaces. Before final installation, coat surfaces behind permanently fixed equipment or furniture with prime coat only.

b) Coat back sides of access panels, removable or hinged covers, and similar hinged items to match exposed surfaces.

5. Touch up bare areas and shop-applied prime coats that have been damaged. Wire brush, solvent clean, and touch up with same primer as the shop coat.

B. Scheduling: Apply first coat to surfaces that have been cleaned, pretreated, or otherwise prepared for coating as soon as practicable after preparation and before subsequent surface deterioration. 1. Do not apply succeeding coats until previous coat has cured as recommended by

manufacturer. 2. Where manufacturer’s written instructions require sanding, sand between applications to

produce a smooth, even surface. 3. Allow sufficient time between successive coats to permit proper drying. Do not recoat

surfaces until coating has dried to where it feels firm, does not deform or feel sticky under moderate thumb pressure, and application of another coat does not cause undercoat to lift or lose adhesion.

4. If undercoats or other conditions show through final coat, apply additional coats until cured film has a uniform coating finish, color, and appearance. Give special attention to edges, corners, crevices, welds, exposed fasteners, and similar surfaces to ensure that they receive a dry film thickness equivalent to that of flat surfaces.

3.04 FIELD QUALITY CONTROL A. Owner reserves the right to invoke testing procedures at any time and as often as deemed

necessary. B. Owner may direct Contractor to stop applying coatings if test results show materials being

used do not comply with specified requirements. Contractor shall remove noncomplying coating materials from Project site, pay for testing, and recoat surfaces coated with rejected materials. If necessary, Contractor may be required to remove rejected materials from previously coated surfaces if, on recoating with specified materials, the two coatings are not compatible.

3.05 CLEANING A. At end of each workday, remove rubbish, empty cans, rags, and other discarded materials

from Project site. B. After completing coating application, clean spattered surfaces. Remove spattered coatings by

washing, scraping, or other methods. Do not scratch or damage adjacent finished surfaces. 3.06 PROTECTION

CDH-13072 Addendum No. 4

09 9600-4

A. Protect work of other trades, whether being coated or not, against damage from coating operation. Correct damage by cleaning, repairing, replacing, and recoating, as approved by Architect, and leave in an undamaged condition.

B. Provide “Wet Paint” signs to protect newly coated finishes. After completing coating operations, remove temporary protective wrappings provided by others to protect their work.
