PART 3 ‑ EXECUTION

3.1

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. On request, furnish information on characteristics of specified finish materials to ensure compatible primers.

1.

If a potential incompatibility of primers applied by others exists, obtain the following from the primer Applicator before proceeding:

a.

Confirmation of primer's suitability for expected service conditions.

b.

Confirmation of primer's ability to be top coated with materials specified.

2.

Notify Contracting Officer about anticipated problems before using the coatings specified over substrates primed by others.

3.2

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 high‑performance coatings, clean substrates of substances that could impair bond of coatings. Remove oil and grease before cleaning.

1.

Schedule cleaning and coating application so dust and other contaminates from cleaning process will not fall on wet, newly coated surfaces.

C.

Surface Preparation: Clean and prepare surfaces to be coated according to manufacturer's written instructions for each substrate condition and as specified.

1.

Gypsum Substrates: Clean surfaces of dirt, oil, and other foreign substances with scrapers, mineral spirits, and sandpaper, as required. Smoothly sand surfaces exposed to view and dust off.

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.

Tint each undercoat a lighter shade to facilitate identification of each coat if multiple coats of the same material are to be applied. Tint undercoats to match color of finish coat, but provide sufficient difference in shade of undercoats to distinguish each separate coat.

3.3

APPLICATION

A.

General: Apply high‑performance coatings according to manufacturer's written instructions.

1.

Use applicators and techniques best suited for the material being applied.

2.

Do not apply high‑performance coatings over dirt, rust, scale, grease, moisture, scuffed surfaces, or conditions detrimental to forming a durable coating film.

3.

Coating colors, surface treatments, and finishes are indicated in the coating system descriptions.

4.

Provide finish coats compatible with primers used.

5.

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

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.

B.

Scheduling Coating: 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.

The number of coats and film thickness required is the same regardless of application method.

a.

Do not apply succeeding coats until previous coat has cured as recommended by manufacturer.

b.

Where manufacturer's written instructions require sanding, sand between applications to produce a smooth, even surface.

c.

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.

2.

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.

C.

Application Procedures: Apply coatings by brush, roller, spray, or other applicators according to manufacturer's written instructions.

1.

Brush Application: Use brushes best suited for material applied and of appropriate size for the surface or item being coated.

a.

Apply primers and first coats by brush unless manufacturer's written instructions permit using roller or mechanical applicators.

b.

Brush out and work brush coats into surfaces in an even film.

c.

Eliminate cloudiness, spotting, holidays, laps, brush marks, runs, sags, ropiness, or other surface imperfections. Neatly draw glass lines and color breaks.

2.

Rollers: Use rollers of carpet, velvet back, or high‑pile sheep's wool as recommended by manufacturer for the material and texture required.

3.

Spray Equipment: Use mechanical methods to apply coating if permitted by manufacturer's written instructions and governing regulations.

a.

Use spray equipment with orifice size recommended by manufacturer for material and texture required.

b.

Apply each coat to provide the equivalent hiding of brush‑applied coats.

c.

Do not double back with spray equipment building‑up film thickness of two coats in one pass, unless recommended by manufacturer.

D.

Minimum Coating Thickness: Apply each material no thinner than manufacturer's recommended spreading rate. Provide total dry film thickness of the entire system as recommended by manufacturer.

E.

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.

1.

Recoat primed and sealed substrates if there is evidence of suction spots or unsealed areas in first coat, to ensure a finish coat with no burn‑through or other defects caused by insufficient sealing.

F.

Completed Work: Match approved Samples for color, texture, and coverage. Remove, refinish, or recoat work that does not comply with specified requirements.

3.4

CLEANING

A.

Cleanup: At end of each workday, remove rubbish, empty cans, rags, and other discarded materials from Project site.

1.

After completing coating application, clean spattered surfaces. Remove spattered coatings by washing, scraping, or other methods. Do not scratch or damage adjacent finished surfaces.

3.6

PROTECTION

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 Contracting Officer, and leave in an undamaged condition.

1.

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

2.

At completion of construction activities of other trades, touch up and restore damaged or defaced coated surfaces. Comply with procedures specified in PDCA(P1.
