3.04 APPLICATION

A. Surface preparation and coating system are as indicated in the “Coating Schedule” at the end of this Section, or noted on Drawings.

09 97 20 - 8 RIVAN 190497

B. Use equipment and techniques best suited for substrate and type of material being applied.

C. Apply in accordance with manufacturer’s directions.

1. Do not apply in snow, rain, fog, mist, or damp surfaces.

2. Allow wet surfaces to dry thoroughly and attain the temperature and conditions specified before proceeding with or continuing the painting operation.

3. Work may continue during inclement weather only if areas and surfaces are enclosed and temperatures within the area can be maintained within limits specified during application and drying periods.

D. Avoid degradation and contamination of surfaces and avoid intercoat contamination.

1. Surfaces shall be free from grease, oil, abrasives, and other contaminants that may have an adverse affect on coating application, bonding, curing, or performance.

2. Clean contaminated surfaces before applying next coat.

3. Do not paint over dirt, rust, scale, grease, moisture, scuffed surfaces, or conditions otherwise detrimental to formation of a durable system.

E. Brush-apply primer or intermediate on all welds and edges prior to general application of finish coat.

F. Apply caulking to flange interfaces, gaps, and intermittent weld seams.

G. Provide finish coats that are compatible with primers used. Prime and intermediate coats shall be lighter than subsequent coat.

H. Provide application thickness to specific mil requirements. Mil thicknesses referenced are in dry mil thickness.

I. All paint systems are “full coverage.” Where discrepancies between manufacturer’s square foot coverage and mil thickness occur, use mil thickness requirements.

J. Where voids are present exposing the substrate or undercoats, apply additional coats until a uniform color and finish is obtained. Give special attention to insure that surfaces, including edges, corners, crevices, welds, and exposed fasteners receive a dry film thickness equivalent to that of flat surfaces.

K. Do not apply additional coats until Engineer has had the opportunity to inspect and approve previous coat.

L. Unless otherwise indicated, match color of adjacent walls or equipment when painting conduit, miscellaneous brackets, hangers, and supports.

M. Smooth out runs or sags immediately, or remove and recoat entire surface.

N. Allow preceding coats to dry before recoating. Recoat within time limits specified by coating manufacturer.

O. Do not apply coatings to the following surfaces:

1. Factory or installer-finished items.

2. Anodized aluminum, stainless steel, or other pre-finished metal.

3. Moving parts of operating devices.

4. Sprinkler heads or other fire detection/suppression elements.

5. Code required labels or equipment nameplates.

3.05 QUALITY CONTROL

A. Contractor shall provide all necessary equipment to monitor and record the information required on the Daily Application Record.

1. Equipment shall be in good condition.

2. Operational within its design range.

RIVAN 190497 09 97 20 - 9

3. Calibrated as required by the specified standard for use of each device.

B. Maintain a copy of the following information at the site:

1. Product Data Sheets.

2. Safety Data Sheets (SDS).

3. Contract Document and submittals.

4. Daily Application Record.

a. Record information (in English) on form located at the end of this Section.

C. Owner’s representative may be on site to observe the application of each coating, and the preparation of each substrate.

D. Provide safe and complete access to all surfaces for observation by Owner and/or Engineer.

E. Prepare rigging so that all surfaces are within arm’s reach of observer.

F. Measure wet paint with wet film thickness gages.

G. Provide DFT measurements for all coatings in accordance with SSPC-PA2.

H. Perform Holiday testing in accordance with NACE RPO 188 as directed by Engineer.

I. Correct any deficiencies observed or detected by field testing as directed by Engineer.

3.06 CLEANING AND PROTECTION

A. During progress of Work, remove discarded materials, rubbish, cans, and rags at end of each workday from the Site.

B. Furnish drop cloths, shields, and protective methods to prevent spray or droppings from disfiguring other surfaces.

C. Upon completion of Work:

1. Clean window glass and spattered surfaces.

2. Remove spattered paint by washing and scraping, using care not to scratch or otherwise damage finished surfaces.

D. Protect Work of other trades against damage. Correct any damage by cleaning, repairing or replacing, and repainting.

E. Provide “Wet Paint” signs as required to protect newly-painted finishes. Remove temporary protective wrappings provided for protection of Work, after completion of painting operations.

F. At completion of Work of other trades, touch-up and restore damaged or defaced surfaces.
