PART 3 - EXECUTION

3.1

EXAMINATION

Examine substrates and conditions under which painting will be performed for compliance with requirements for application of paint. Do not begin paint application until unsatisfactory conditions have been corrected.

Start of painting will be construed as the Applicator's acceptance of surfaces and conditions within a particular area.

3.2

PREPARATION

GENERAL PROCEDURES: Remove hardware and hardware accessories, plates, machined surfaces, lighting fixtures and similar items in place that are not to be painted, or provide surface‑applied protection prior to surface preparation and painting. Remove these items if necessary for complete painting of the items and adjacent surfaces. Following completion of painting operations in each space or area, have items reinstalled by workers skilled in the trades involved.

Clean surfaces before applying paint or surface treatments. Remove oil and grease prior to cleaning. Schedule cleaning and painting so that dust and other contaminants from the cleaning process will not fall on wet, newly painted surfaces.

SURFACE PREPARATION: Clean and prepare surfaces to be painted in accordance with the manufacturer's instructions for each particular substrate condition and as specified.

Provide barrier coats over incompatible primers or remove and reprime. Notify Technical Representative of the Contracting Officer (CEG Inspector) in writing of problems anticipated with using the specified finish‑coat material with substrates primed by others.

CEMENTITIOUS MATERIALS: Prepare concrete, concrete masonry block, cement plaster, and mineral‑fiber‑reinforced cement panel surfaces to be painted. Remove efflorescence, chalk, dust, dirt, grease, oils, and release agents. Roughen as required to remove glaze. If hardeners or sealers have been used to improve curing, use mechanical methods of surface preparation.

Use abrasive blast‑cleaning methods if recommended by the paint manufacturer.

Determine alkalinity and moisture content of surfaces by performing appropriate tests. If surfaces are sufficiently alkaline to cause blistering and burning of finish paint, correct this condition before application. Do not paint surfaces where moisture content exceeds that permitted in manufacturer's printed directions.

Clean concrete floors to be painted with a 5 percent solution of muriatic acid or other etching cleaner. Flush the floor with clean water to remove acid, neutralize with ammonia, rinse, allow to dry, and then vacuum before painting.

D.

WOOD: Clean surfaces of dirt, oil, and other foreign substances with scrapers, mineral spirits, and sandpaper, as required. Sand surfaces exposed to view smooth and dust off.

Scrape and clean small, dry, seasoned knots and apply a thin coat of white shellac or other recommended knot sealer before application of primer. After priming, fill holes and imperfections in finish surfaces with putty or plaster wood filler. Sand smooth when dried.

Prime, stain, or seal wood to be painted immediately upon delivery. Primed edges, ends, faces, undersides, and backsides of wood, including exterior wood trim, cabinets, counters, cases, and paneling.

When transparent finish is required, backprime with spar varnish.

Backprime paneling on interior partitions where masonry, plaster, or other wet wall construction occurs on backside.

Seal tops, bottoms, and cutouts of unprimed wood doors with a heavy coat of varnish or sealer immediately upon delivery.

E.

FERROUS METALS: Clean nongalvanized 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 recommendations of the Steel Structures Painting Council.

Touch up bare areas and shop‑applied prime coats that have been damaged. Wire‑brush, clean with solvents recommended by the paint manufacturer, and touch up with the same primer as the shop coat.

F.

GALVANIZED SURFACES: Clean galvanized surfaces with non‑petroleum‑based solvents so that the surface is free of oil and surface contaminants. Remove pretreatment from galvanized sheet metal fabricated from coil stock by mechanical methods.

G.

MATERIALS PREPARATION: Carefully mix and prepare paint materials in accordance with manufacturer's directions.

Maintain containers used in mixing and application of paint in a clean condition, free of foreign materials and residue.

Stir material before application to produce a mixture of uniform density; stir as required during application. Do not stir surface film into material. Remove film and, if necessary, strain material before using.

Use only thinners approved by the paint manufacturer, and only within recommended limits.

3.3

APPLICATION

Apply paints in accordance with manufacturer's directions. Use applicators and techniques best suited for substrate and type of material being applied.

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

Paint colors, surface treatments, and finishes are indicated in "schedules."

D.

Provide finish coats that are compatible with primers used.

E.

The number of coats and film thickness required is the same regardless of the application method. Do not apply succeeding coats until the previous coat has cured as recommended by the manufacturer. Sand between applications where sanding is required to produce an even smooth surface in accordance with the manufacturer's directions.

F.

Apply additional coats when undercoats, stains, or other conditions show through final coat of paint until paint film is of uniform finish, color, and appearance. Give special attention to ensure that surfaces, including edges, corners, crevices, welds, and exposed fasteners, receive a dry film thickness equivalent to that of flat surfaces.

G.

The term "exposed surfaces" includes areas visible when permanent or built‑in fixtures, convector covers, covers for finned tube radiation, grilles, and similar components are in place. Extend coatings in these areas as required to maintain the system integrity and provide desired protection.

H.

Paint surfaces behind movable equipment and furniture same as similar exposed surfaces. Paint surfaces behind permanently fixed equipment or furniture with prime coat only before final installation of equipment.

I.

Paint interior surfaces of ducts, where visible through registers or grilles, with a flat, nonspecular black paint.

J.

Paint backsides of access panels and removable or hinged covers to match exposed surfaces.

K.

Finish exterior doors on tops, bottoms, and side edges same as exterior faces.

L.

Sand lightly between each succeeding enamel or varnish coat.

M.

Omit primer on metal surfaces that have been shop‑primed and touch up painted.

N.

SCHEDULING PAINTING: Apply first coat to surfaces that have been cleaned, pretreated, or otherwise prepared for painting as soon as practicable after preparation and before subsequent surface deterioration.

Allow sufficient time between successive coats to permit proper drying. Do not recoat until paint has dried to where it feels firm, and does not deform or feel sticky under moderate thumb pressure and where application of another coat of paint does not cause lifting or loss of adhesion of the undercoat.

O.

MINIMUM COATING THICKNESS: Apply materials at not less than the manufacturer's recommended spreading rate. Provide a total dry film thickness of the entire system as recommended by the manufacturer.

P.

MECHANICAL AND ELECTRICAL WORK: Painting mechanical and electrical work is limited to items exposed in mechanical equipment rooms and in occupied spaces. Painting not required on factory finished surfaces.

Mechanical items to be painted include but are not limited to:

Piping, pipe hangers, and supports.

Heat exchangers.

Tanks.

Ductwork.

Insulation.

f.

Supports.

g.

Motors and mechanical equipment.

h.

Accessory items.

Electrical items to be painted include but are not limited to:

Conduit and fittings.

Switchgear.

Q.

BLOCK FILLERS: Apply block fillers to concrete masonry block at a rate to ensure complete coverage with pores filled.

R.

PRIME COATS: Before application of finish coats, apply a prime coat of material as recommended by the manufacturer to material that is required to be painted or finished and has not been prime coated by others. Recoat primed and sealed surfaces where evidence of suction spots or unsealed areas in first coat appears, to assure a finish coat with no burn through or other defects due to insufficient sealing.

S.

PIGMENTED (OPAQUE) FINISHES: Completely cover to provide an opaque, smooth surface of uniform finish, color, appearance, and coverage. Cloudiness, spotting, holidays, laps, brush marks, runs, sags, ropiness, or other surface imperfections will not be acceptable.

T.

TRANSPARENT (CLEAR) FINISHES: Use multiple coats to produce a glass‑smooth surface film of even luster. Provide a finish free of laps, cloudiness, color irregularity, runs, brush marks, orange peel, nail holes, or other surface imperfections.

Provide satin finish for final coats.

U.

COMPLETED WORK: Match approved samples for color, texture, and coverage. Remove, refinish, or repaint work not in compliance with specified requirements.

3.4

FIELD QUALITY CONTROL

The Government reserves the right to invoke the following test procedure at any time and as often as the Government deems necessary during the period when paint is being applied:

The Government will engage the services of an independent testing laboratory to sample the paint material being used. Samples of material delivered to the project will be taken, identified, sealed, and certified in the presence of the Contractor.

The testing laboratory will perform appropriate tests for the following characteristics as required by the Government:

Quantitative materials analysis.

Abrasion resistance.

Apparent reflectivity.

Flexibility.

Washability.

f.

Absorption.

g.

Accelerated weathering.

h.

Dry opacity.

i.

Accelerated yellowness.

j.

Recoating.

k.

Skinning.

l.

Color retention.

m.

Alkali and mildew resistance.

If test results show material being used does not comply with specified requirements, the Contractor may be directed to stop painting, remove noncomplying paint, pay for testing, repaint surfaces coated with rejected paint, and remove rejected paint from previously painted surfaces if, upon repainting with specified paint, the two coatings are incompatible.

3.5

CLEANING

CLEANUP: At the end of each workday, remove empty cans, rags, rubbish, and other discarded paint materials from the site.

Upon completion of painting, clean glass and paint‑spattered surfaces. Remove spattered paint by washing and scraping, using care not to scratch or damage adjacent finished surfaces.

3.6

PROTECTION

Protect work of other trades, whether to be painted or not, against damage by painting. Correct damage by cleaning, repairing or replacing, and repainting, as acceptable to the Technical Representative of the Contracting Officer (CEG Inspector).

Provide "wet paint" signs to protect newly painted finishes. Remove temporary protective wrappings provided by others for protection of their work after completion of painting operations.

At completion of construction activities of other trades, touch up and restore damaged or defaced painted surfaces.

3.7

EXTRA STOCK

Furnish to the Contracting Officer, at Substantial Completion, extra stocks of paint products as shown below. Extra stock shall be from same manufacturer as materials installed, in unopened full gallon containers marked to correspond with Government's Color Schedule.

Furnish one gallon for each (20) twenty gallons (or fraction thereof) of each paint color (or stain) and type used.
