PART 3 EXECUTION

3.1 PROTECTION OF AREAS AND SPACES NOT TO BE PAINTED: Prior to surface preparation and coating applications, remove, mask, or otherwise protect, hardware, hardware accessories, machined surfaces, radiator covers, plates, lighting fixtures, public and private property, and other such items not to be coated that are in contact with surfaces to be coated. Following completion of painting, workmen skilled in the trades involved must reinstall removed items. Restore surfaces contaminated by coating materials, to original condition, and repair damaged items.

3.2 SURFACE CONDITION: Remove dirt, splinters, loose particles, grease, oil, disintegrated coatings, rust, and other foreign matter and substances deleterious to coating performance as specified for each substrate before application of paint or surface treatments in accordance with the manufacturer's specifications. Oil and grease must be removed prior to mechanical cleaning. Cleaning must be programmed so that dust and other contaminants will not fall on wet, newly painted surfaces.

3.3 EXISTING COATED SURFACES WITH MINOR DEFECTS: Sand, spackle, and treat minor defects to render them to match adjacent surfaces finish. Minor defects are defined as scratches, nicks, cracks, gouges, spalls, alligatoring, chalking, and irregularities due to partial peeling of previous coatings. Remove chalking by sanding so that when tested in accordance with ASTM D4214, the chalk rating is not less than 8.

3.4 SUBSTRATE REPAIR: Repair substrate surfaces damaged during coating removal to match adjacent surfaces and finish.

3.5 PREPARING EXISTING AND NEW NON-FERROUS METALLIC SURFACES:

Prepare surface to Steel Structures Painting Code (SSPC) SP-6, except prepare galvanized steel to SSPC SP-16. Unless otherwise noted in 05 10 17.01

3.6 PREPARING CONCRETE AND MASONRY SURFACES: Remove the following deleterious substances: Dirt, Chalking, Grease, Oil, Fungus, Mold, Loose Particles, failing paint, and Efflorescence using the gentlest means practicable. Repair or fill mortar joints and minor defects, including but not limited to spalls, in accordance with manufacturer's recommendations and prior to coating application. Allow surfaces to cure a minimum of 30 days before painting.

SECTION 09 90 00 PAGE 3 OF 5

3.7 PREPARING GYPSUM BOARD, PLASTER, AND STUCCO: Plaster and stucco must be clean and free from loose matter; gypsum board must be dry. Remove loose dirt and dust by brushing with a soft brush, rubbing with a dry cloth or vacuum-cleaning prior to application of the first coat material. Allow new plaster to age a minimum of 30 days before preparation for painting.

3.8 PREPARING WOOD SUBSTRATES: Scrape and clean knots. Before applying primer, apply coat of knot sealer recommended in writing by topcoat manufacturer for exterior use in paint system indicated. Sand surfaces that will be exposed to view, and dust off.

Prime edges, ends, faces, undersides, and backsides of wood. After priming, fill holes and imperfections in the finish surfaces with putty or plastic wood filler. Sand smooth when dried.

3.9 COATING APPLICATION: At the time of application, paint must show no signs of deterioration. Uniform suspension of pigments must be maintained during application.

Unless otherwise specified or recommended by the paint manufacturer, paint may be applied by brush, roller, or spray. Thoroughly work coating materials into joints, crevices, and open spaces. Special attention must be given to insure that all edges, corners, crevices, welds, and rivets receive a film thickness equal to that of adjacent painted surfaces. Each coat of paint must be applied so dry film must be of uniform thickness and free from runs, drops, ridges, waves, pinholes or other voids, laps, brush marks, and variations in color, texture, and finish. Hiding must be complete. Touch up damaged coatings before applying subsequent coats. Interior areas must be broom clean and dust free before and during the application of coating material. Coat surfaces with the following one coat of primer, one coat of undercoat or intermediate coat, and one topcoat to match adjacent surfaces. Topcoat coating must match adjacent surfaces where newly painting surfaces abut existing previously painted surfaces.

3.10 DRYING TIME: Allow time between coats, as recommended by the coating manufacturer, to permit thorough drying, but not to present topcoat adhesion problems.

Provide each coat in specified condition to receive next coat.

3.11 PRIMERS AND INTERMEDIATE COATS: Do not allow primers or intermediate coats to dry more than 30 days, or longer than recommended by manufacturer, before applying subsequent coats. Follow manufacturer's recommendations for surface preparation if primers or intermediate coats are allowed to dry longer than recommended by manufacturers of subsequent coatings. Each coat must cover surface of preceding coat or surface completely and there must be a visually perceptible difference in shades of successive coats.

3.12 SHEEN: Provide semi-gloss sheen for trim, doors, exterior elements and accent walls.

Provide flat sheen for ceilings. Provide eggshell sheen in all other locations unless otherwise noted.
