1.4	DEFINITIONS
A.	General: Standard coating terms defined in ASTM D16.
1.	Flat refers to a lusterless or matte finish with a gloss range below 15 when measured at an 85 degree meter.
2.	Eggshell refers to low-sheen finish with a gloss range between 20 and 35 when measured at a 60 degree meter.
3.	Semi-Gloss refers to medium-sheen finish with a gloss range between 35 and 70 when measured at a 60 degree meter.
4.	Full gloss refers to high-sheen finish with a gloss range more than 70 when measured at a 60 degree meter.
B.	Environments: The following terms distinguish between different corrosive exposures:
1.	Severe Environments: Highly corrosive industrial atmospheres with sustained exposure to high humidity and condensation and with frequent cleaning using strong chemicals. Environments with heavy concentrations of strong chemical fumes and frequent splashing and spilling of harsh chemical products are severe environments.
2.	Moderate Environments: Corrosive industrial atmospheres with intermittent exposure to high humidity and condensation, occasional mold and mildew development, and regular cleaning with strong chemicals. Environments with exposure to heavy concentrations of chemical fumes and occasional splashing and spilling of chemical products are moderate environments.
3.	Mild Environments: Industrial atmospheres with normal exposure to moderate humidity and condensation, occasional mold and mildew development, and infrequent cleaning with strong chemicals. Environments with low levels of mild chemical fumes and occasional splashing and spilling of chemical products are mild environments. Normal outdoor weathering is also considered a mild environment.

PART 3    EXECUTION
3.1	EXAMINATION
A.	Do not begin installation until substrates have been properly prepared.
B.	If substrate preparation is the responsibility of another installer, notify Architect of unsatisfactory preparation before proceeding.
3.2	PREPARATION
A.	General: Remove hardware and hardware accessories, plates, machined surfaces, lighting fixtures, and similar items already installed that are not to be painted. If removal is impractical or impossible because of size or weight of the item, provide surface-applied protection before surface preparation and painting.
1.	After completing painting operations in each space or area, reinstall items removed using workers skilled in the trades involved.
B.	Cleaning: Before applying paint or other surface treatments, clean substrates of substances that could impair bond of the various coatings. Remove oil and grease before cleaning.
1.	Schedule cleaning and painting so dust and other contaminants from the cleaning process will not fall on wet, newly painted surfaces.
C.	Surface Preparation: Clean and prepare surfaces to be painted according to manufacturer's written instructions for each substrate condition and as specified.
1.	Provide barrier coats over incompatible primers or remove and reprime.
2.	Cementitious Substrates: Prepare concrete, brick, concrete masonry block, and cement plaster surfaces to be coated. 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 to prepare surfaces.
a.	Use abrasive blast-cleaning methods if recommended by coating manufacturer.
b.	Determine alkalinity and moisture content of surfaces by performing appropriate tests. If surfaces are sufficiently alkaline to cause the finish paint to blister and burn, correct this condition before application. Do not coat surfaces if moisture content exceeds that permitted in manufacturer's written instructions.
3.	Wood 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.
a.	Scrape and clean small, dry, seasoned knots, and apply a thin coat of white shellac or other recommended knot sealer, before applying primer.
b.	Immediately on delivery, prime edges, ends, faces, undersides, and backsides of wood to be coated.
c.	After priming, fill holes and imperfections in the finish surfaces with putty or plastic wood filler. Sand smooth when dried.
4.	Ferrous Metal Substrates: 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.
a.	Blast-clean steel surfaces as recommended by coating manufacturer and according to SSPC-SP 6.
b.	Treat bare and sandblasted or pickled clean metal with a metal treatment wash coat before priming.
c.	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.
5.	Non-Ferrous Metal Substrates: Clean non-ferrous and galvanized surfaces according to manufacturer's written instructions for the type of service, metal substrate, and application required.
a.	Remove pretreatment from galvanized sheet metal fabricated from coil stock by mechanical methods.
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.
4.	Tinting: Tint each undercoat a lighter shade to simplify identification of each coat when multiple coats of same material are applied. Tint undercoats to match the color of the finish coat, but provide sufficient differences in shade of undercoats to distinguish each separate coat.
3.3	APPLICATION
A.	General: Apply paint according to manufacturer's written instructions. Use applicators and techniques best suited for substrate and type of material being applied.
B.	General: Apply high-performance coatings according to manufacturer's written instructions.
