EXECUTION

JOB CONDITIONS:

Safety: Observe required safety regulations and manufacturer's warning and instructions for storage, handling and application of painting materials.

Take necessary precautions to protect personnel and property from hazards due to falls, injuries, toxic fumes, fire, explosion, or other harm.

Deposit soiled cleaning rags and waste materials in metal containers approved for that purpose. Dispose of such items off the site at end of each day’s work.

Atmospheric and Surface Conditions:

Do not apply coating when air or substrate conditions are:

Less than 3 degrees C (5 degrees F) above dew point.

Below 10 degrees C (50 degrees F) or over 35 degrees C (95 degrees F), unless specifically pre-approved by the COR and the product manufacturer. Under no circumstances are application conditions to exceed manufacturer recommendations.

When the relative humidity exceeds 85 percent; or to damp or wet surfaces; unless otherwise permitted by the paint manufacturer’s printed instructions.

Maintain interior temperatures until paint dries hard.

Do no exterior painting when it is windy and dusty.

Do not paint in direct sunlight or on surfaces that the sun will warm.

Apply only on clean, dry and frost-free surfaces except as follows:

Apply water thinned acrylic and cementitious paints to damp (not wet) surfaces only when allowed by manufacturer's printed instructions.

Concrete and masonry when permitted by manufacturer’s recommendations, dampen surfaces to which water thinned acrylic and cementitious paints are applied with a fine mist of water on hot dry days to prevent excessive suction and to cool surface.

Varnishing:

Apply in clean areas and in still air.

Before varnishing vacuum and dust area.

Immediately before varnishing wipe down surfaces with a tack rag.

inspection:

Examine the areas and conditions where painting and finishing are to be applied and correct any conditions detrimental to the proper and timely completion of the work. Do not proceed with the work until unsatisfactory conditions are corrected to permit proper installation of the work.

general workmanship requirements:

Application may be by brush or roller. Spray application only upon acceptance from the COR in writing.

Furnish to the COR a painting schedule indicating when the respective coats of paint for the various areas and surfaces will be completed. This schedule is to be kept current as the job progresses.

Protect work at all times. Protect all adjacent work and materials by suitable covering or other method during progress of work. Upon completion of the work, remove all paint and varnish spots from floors, glass and other surfaces. Remove from the premises all rubbish and accumulated materials of whatever nature not caused by others and leave work in a clean condition.

Remove and protect hardware, accessories, device plates, lighting fixtures, and factory finished work, and similar items, or provide in place protection. Upon completion of each space, carefully replace all removed items by workmen skilled in the trades involved.

When indicated to be painted, remove electrical panel box covers and doors before painting walls. Paint separately and re-install after all paint is dry.

Materials are to be applied under adequate illumination, evenly spread and flowed on smoothly to avoid runs, sags, holidays, brush marks, air bubbles and excessive roller stipple.

Apply materials with a coverage to hide substrate completely. When color, stain, dirt or undercoats show through final coat of paint, the surface is to be covered by additional coats until the paint film is of uniform finish, color, appearance and coverage, at no additional cost to the Government.

All coats are to be dry to manufacturer’s recommendations before applying succeeding coats.

All suction spots or “hot spots” in plaster after the application of the first coat are to be touched up before applying the second coat.

Do not apply paint behind frameless mirrors that use mastic for adhering to wall surface.

SURFACE PREPARATION:

General:

The Contractor shall be held wholly responsible for the finished appearance and satisfactory completion of painting work. Properly prepare all surfaces to receive paint, which includes cleaning, sanding, and touching-up of all prime coats applied under other Sections of the work. Broom clean all spaces before painting is started. All surfaces to be painted or finished are to be completely dry, clean and smooth.

See other sections of specifications for specified surface conditions and prime coat.

Perform preparation and cleaning procedures in strict accordance with the paint manufacturer’s instructions and as herein specified, for each particular substrate condition.

Clean surfaces before applying paint or surface treatments with materials and methods compatible with substrate and specified finish. Remove any residue remaining from cleaning agents used. Do not use solvents, acid, or steam on concrete and masonry. Schedule the cleaning and painting so that dust and other contaminants from the cleaning process will not fall in wet, newly painted surfaces.

Maximum Moisture Content of Substrates: When measured with an electronic moisture meter as follows:

Concrete: 12 percent.

Fiber-Cement Board: 12 percent.

Masonry (Clay and CMU’s): 12 percent.

Wood: 15 percent.

Gypsum Board: 12 percent.

Plaster: 12 percent.

Masonry, Concrete, Cement Board, Cement Plaster and Stucco:

Clean and remove dust, dirt, oil, grease efflorescence, form release agents, laitance, and other deterrents to paint adhesion.

Use emulsion type cleaning agents to remove oil, grease, paint and similar products. Use of solvents, acid, or steam is not permitted.

Remove loose mortar in masonry work.

Replace mortar and fill open joints, holes, cracks and depressions with new mortar specified in Section 04 05 13, MASONRY MORTARING // Section 04 05 16, MASONRY GROUTING //. Do not fill weep holes. Finish to match adjacent surfaces.

Neutralize Concrete floors to be painted by washing with a solution of 1.4 Kg (3 pounds) of zinc sulfate crystals to 3.8 L (1 gallon) of water, allow to dry three (3) days and brush thoroughly free of crystals.

Repair broken and spalled concrete edges with concrete patching compound to match adjacent surfaces as specified in Division 03, CONCRETE Sections. Remove projections to level of adjacent surface by grinding or similar methods.

Gypsum Plaster and Gypsum Board:

Remove efflorescence, loose and chalking plaster or finishing materials.

Remove dust, dirt, and other deterrents to paint adhesion.

Fill holes, cracks, and other depressions with CID-A-A-1272A finished flush with adjacent surface, with texture to match texture of adjacent surface. Patch holes over 25 mm (1-inch) in diameter as specified in Section for plaster or gypsum board.

PAINT PREPARATION:

Thoroughly mix painting materials to ensure uniformity of color, complete dispersion of pigment and uniform composition.

Do not thin unless necessary for application and when finish paint is used for body and prime coats. Use materials and quantities for thinning as specified in manufacturer's printed instructions.

Remove paint skins, then strain paint through commercial paint strainer to remove lumps and other particles.

Mix two (2) component and two (2) part paint and those requiring additives in such a manner as to uniformly blend as specified in manufacturer's printed instructions unless specified otherwise.

For tinting required to produce exact shades specified, use color pigment recommended by the paint manufacturer.

APPLICATION:

Start of surface preparation or painting will be construed as acceptance of the surface as satisfactory for the application of materials.

Unless otherwise specified, apply paint in three (3) coats; prime, body, and finish. When two (2) coats applied to prime coat are the same, first coat applied over primer is body coat and second coat is finish coat.

Apply each coat evenly and cover substrate completely.

Allow not less than 48 hours between application of succeeding coats, except as allowed by manufacturer's printed instructions, and approved by COR.

SPEC WRITER NOTE: Do not allow spray painting at existing buildings occupied during the course of the work. Spray painting may be allowed in certain areas of new additions or separate buildings. Coordinate restrictions with COR.
