3.06 APPLICATION
A. Workmanship

1. Coated surfaces shall be free from excessive runs, sags, drips, ridges, waves, laps, and brush marks. Coats shall be applied to produce an even film of uniform thickness completely coating corners and crevices. Minor and infrequent runs and sags which are within the total specified DFT plus a few mils – no more than 10% more mils than the specified total DFT shall be acceptable. Frequent runs or sags which exceed these limits or are detrimental to coating system performance are not acceptable.

2. The Contractor's spray equipment shall be designed for application of the materials specified. Compressors shall have suitable traps and filters to remove water and oils from the air. Spray equipment shall be equipped with mechanical agitators, pressure gages, and pressure regulators, and properly sized spray tips.

3. Each coating application be applied evenly and sharply cut to line. Care shall be exercised to avoid overspray or spattering paint on surfaces not to be coated.

Glass, hardware, floors, roofs, and other adjacent areas and installations shall be protected by taping, drop cloths, or other suitable measures.

4. Coating applications method shall be as recommended by the coating manufacturer.

5. Allow each coat to cure or dry thoroughly, according to the coating manufacturer’s printed instructions, prior to recoating.

6. Vary color for each successive coat for coating systems when possible. When coating complex steel shapes, prior to overall coating system application, stripe coat welds, edges of structural steel shapes, metal cutouts, pits in steel surfaces, or rough surfaces with the prime coat. This involves applying a separate coat using brushes or rollers to ensure proper coverage. Stripe coat via spray application is not permitted.

B. Coating Properties – Mixing and Thinning

1. Coatings, when applied,shall provide a satisfactory film and smooth even surface.

Glossy undercoats shall be lightly sanded to provide a surface suitable for the proper application and adhesion of subsequent coats. Coating materials shall be thoroughly stirred,strained, and kept at a uniform consistency during application.

Coatings consisting of two or more componentsshall be mixed in accordance with the coating manufacturer’s instructions. Where necessary to suit the conditions of the surface, temperature, weather and method of application, the coating may be thinned as recommended by the coating manufacturer immediately prior to use. The VOC of the coating as applied shall comply with prevailing air pollution control regulations. Unless otherwise specified, coatings shall not be reduced more than necessary to obtain the proper application characteristics. Thinner shall be as recommended by the coating manufacturer.

2. Mixing of partial “kits” is strictly prohibited unless authorized in writing by the coating manufacturer and the City. This prohibition also applies to coatings

West Yost – December 2024

09960 - 20
High Performance Coatings
City of Milpitas
WellUpgrades Program
McCandless Well Facility
mixed for touchup or repairs. If authorized to mix partial kits, the contractorshall utilize containers with appropriate graduated markings/calibrated weight scales.

C. Environmental Conditions

1. Provide adequate heat, ventilation, and dehumidification to ensure that the coating manufacturer’s environmental requirements are met and to ensure no loss of production days due to failure to meet coating manufacturer’s environmental requirements.

2. Provide sufficient and continuous ventilation and air movement across coated substrates to remove volatile constituents (solvent) throughout the manufacturer’s published curing period.

3. Air and surface temperatures: Prepare surfaces, apply and cure coatings within air and surface temperature range recommended by coating manufacturer.

4. Relative humidity: Prepare surfaces, apply and cure coatings within relative humidity range in accordance with coating manufacturer’s instructions.

5. Dew Point: Do not apply coatings unless the temperature of the dew point is 5°F or greater than the temperature of the substrate.

6. Precipitation: Do not apply coatings in rain, snow, fog, or mist.

7. Wind: Do not spray apply coatings when the wind direction and velocity are such that overspray may result in property damage.

D. Protection of Coated Surfaces

1. Items which have been coated shall not be handled, worked on, or otherwise disturbed, until the coating is completely dry and hard. After delivery at the site, and upon permanent erection or installation, shop-coated metalwork shall be recoated or retouched with specified coating when it is necessary to maintain the integrity of the film.

E. Film Thickness and Continuity

1. WFT of the first coat of the coating system and subsequent coats shall be verified by the contractor, during application of each coat.

2. Coatingsshall be applied to the minimum dry film thickness specified asindicated on the CDS. Dry film thicknessshall be determined using the appropriate industry standard for the substrate (SSPC-PA 2, SSPC-PA 9, or ASTM D1400). Coatings determined to be above the maximum dry film thickness, as indicated herein or on the coating manufacturer’s product data sheet, will be removed at the City’s discretion.

3. The Inspector may, but is not required to, also measure coating thickness, at random locations, after each coat. SSPC –PA 2 (Level 1) is only to be used for the calibration of dry film thickness gauges. This is a minimum maximum dry film thickness specification. Dry film thickness readings will not be averaged. All inspection equipment shall be supplied by the Contractor. All equipment shall have current calibration certificates. The City reserves the right to use their own equipment at any time.

4. In testing for continuity of coating about welds, projections (such as bolts and nuts), and crevices, the City shall determine the minimum conductivity for smooth areas of like coating where the dry mil thickness has been accepted. This conductivity shall be the minimum required for these rough or irregular areas.

Pinholes and holidays shall be recoated to the required coverage.

5. The ability to obtain specified film thickness is generally compromised when brush or roller application methods are used and, therefore, more coats may be needed to be applied to achieve the specified dry film thickness.

6. For concrete substrates, the Contractor shall apply a complete skim coat of the specified filler-surfacer material over the entire substrate prior to application of the coating system. This material shall be applied such that all open air voids and “bug holes” in the concrete substrate are completely filled prior to coating application.

F. Special Requirements

1. Before erection, the Contractor shall apply all but the final finish coat to interior surfaces of roof plates, roof rafters and supports, pipe hangers, piping in contact with hangers, and contact surfaces which are inaccessible after assembly. The final coat shall be applied after erection. Structural friction connections and high tensile bolts and nuts shall be coated after erection. Areas damaged during erection shall be hand-cleaned or power-tool cleaned and recoated with primer coat prior to the application of subsequent coats. Touch-up of surfaces shall be performed after installation. Surfaces to be coated shall be clean and dry at the time of application. Except for those to be filled with grout, the underside of equipment bases and supportsthat have not been galvanized shall be coated with at least two coats of intermediate coat specified for System 1 prior to setting the equipment in place. Provide coating system terminations at leading edges and transitions to other substrates in accordance with the coating manufacturer’s recommendations or detail drawings.

G. Soluble Salt Contamination of Metal Substrates

1. Contractor shall test in accordance with SSPC Guide 15 metal substrates to be coated that have been exposed to sea water or coastal air or to industrial fallout of particulate or other sources of soluble chlorides (such as waste water exposure). If testing indicates chloride levels in excess of 25 ppm exist after the surface preparation has been completed. The Contractor shall reclean and prepare these surfaces until chloride levels are below 25 ppm.
