B201001 1.4 EXTERIOR INSULATION AND FINISH SYSTEM (EIFS)

NOTE:  EIFS systems are not recommended as the primary exterior material for Navy facilities, except when required to match adjacent structures.  Approval to include EIFS in a RFP should be obtained by the appropriate FAC/FEC.  The systems are available in two classes:  PB and PM.

Class PB Systems are typically composed of a 1/16 inch to 1/4 inch (2 mm to 6 mm) cementitious or non-cementitious base coat, one or more layers of polymer-coated glass fiber mesh, and a non-cementitious finish coat.  PB systems are most commonly used over molded expanded polystyrene (MEPS) insulation which is adhesively attached to the substrate.  The non-cementitious base coat systems have good impact resistance but may be punctured by sharp objects.  The MEPS insulation allows water vapor migration, which can either ventilate the system beneficially or allow moisture into the substrate.  Class PB EIFS should not be used in first floor, high traffic areas, or in areas where pedestrians congregate.  Where so used, they must have at least one layer of 20 ounce (567 grams) reinforcing fabric mesh.  Class PB systems are the least expensive and most widely used of the two classes.

Class PM Systems are typically composed of a 1/4 inch to 3/8 inch (6 mm to 9 mm) thick, rigid, polymer-modified cementitious base coat, a polymer-coated fiber mesh, and a cementitious finish coat.  They are most commonly used over an extruded expanded-polystyrene (XEPS) insulation board, which is mechanically attached to the substrate.  Class PM systems have good puncture resistance, but are susceptible to damage from blunt impacts.  The XEPS insulation allows less water vapor movement.

EIMA TM 101 and 01 EIMA TM 101.86. Refer to the RFP Part 3 Project Program to determine if EIFS is used as the non-primary or the primary exterior finish material for the project. Job-fabricate the exterior insulation and finish system (EIFS) covering consisting of sheathing, water resistive barrier, moisture drainable insulation board system, reinforcing fabric, base coat, finish coat, adhesive, primer, accessories, flashing, sealant, and mechanical fasteners. The system components must be compatible with each other and with the substrate as recommended or approved by, and the products of, a single manufacturer regularly engaged in furnishing Exterior Insulation and Finish Systems. Install all materials using an applicator trained and approved by the system manufacturer in accordance with DOR-approved shop drawings and manufacturer's recommendations. The sealant applicator must also be approved by the EIFS manufacturer.  Provide EIFS Class PB or Class PM. Do not use Class PB EIFS in first floor, high traffic areas, or in areas where pedestrians congregate without at least one layer of 20 ounce (567 grams) reinforcing fabric mesh. Use 1/8 inch (4 mm) minimum thickness for PB finish system. Color of the EIFS finish must be consistent, with no variation noticeable to the DOR. Seal all joints in EIFS in accordance with ASTM C 1481 and as recommended by the manufacturer. Furnish manufacturer's standard warranty for the EIFS. Provide warranty directly to Government and cover a period of not less than 5 years from date Government accepted the work.

Comply with Master Painters Institute requirements for surface degradation analysis, surface preparation, paint and coating selection, paint application restrictions for substrate materials, and paint application.

B201009 1.1 GENERAL REQUIREMENTS

Painting practices must comply with applicable federal, state and local laws enacted to insure compliance with Federal Clean Air Standards.  Apply coating materials in accordance with Society for Protective Coatings (SSPC) PA 1.  SSPC PA 1 methods are applicable to all substrates.

Provide all paint in accordance with the Master Painter Institute (MPI) standards for the exterior architectural surface being finished.  The current MPI, "Approved Product List" which lists paint by brand, label, product name and product code as of the date of contract award, will be used to determine compliance with the submittal requirements of this specification.  The Contractor may choose to use a more current MPI "Approved Product List"; however, only one list may be used for the entire contract. All coats on a particular substrate, or a paint system, must be from a single manufacturer.  No variation from the MPI Approved Products List is acceptable.

Select paint systems for the project in accordance with the MPI Architectural Painting Decision Tree available on the Whole Building Design Guide.  Use this interactive MPI Decision Tree website to identify applicable paint system(s) for the project. The MPI Decision Tree identifies paint systems for each interior or exterior coated surface in "Normal" or "Aggressive" environmental conditions and generally lists the applicable paint systems in descending order of performance.  The paint system at the top of each substrate list generally indicates the highest performing acceptable coating system.

Choose the "Aggressive" environmental conditions in the MPI Decision Tree for exterior systems that are used in moist humid conditions, abrasive conditions, chemical exposure conditions, or within five miles proximity of the ocean or a body of water. Also use "Aggressive " environmental conditions in interior spaces that are exposed to in moist humid conditions, abrasive conditions, chemical exposure conditions, such as bathrooms, shower rooms, kitchens, chemical storage area, swimming pools, laundry, sanitary areas, commercial kitchens, industrial production areas, and hospital operating rooms provide paint systems that comply with the MPI Decision Tree "Aggressive" environmental conditions.

Comply with the following requirements when determining the appropriate paint or coating system from the MPI Decision Tree:

a.    Some of these paint systems are identified with a "NAVFAC Anchor".  This "NAVFAC Anchor" indicates the minimum performing system that NAVFAC will accept for that substrate and environmental conditions.

b.    When multiple "NAVFAC Anchors" are indicated on a certain substrate and environmental condition, provide the "NAVFAC Anchor" paint or coating system that is most appropriate for the facility use.

c.    If only one MPI Decision Tree choice is available for a certain substrate and environmental condition with no indicated NAVFAC preference, provide that sole option for NAVFAC projects.

d.    If the MPI Decision Tree provides multiple choices and no NAVFAC preference is denoted, refer to the Additional RFP Requirements below to determine level of performance.

e.    If the MPI Decision Tree does not identify all paint system applicable to the facility, utilize the MPI Architectural Painting, Exterior Systems Manual to identify other appropriate paint systems for the project. Utilize the "Premium Grade" systems and comply with all limitations stated in the MPI "Approved Product List" for each paint product.  Products having an MPI VOC Range E3 must be given preferential consideration over lower VOC Ranges.  Use higher performing paint systems unless the lower performing paint system can be justified based on a lifecycle cost to include surface preparation, application, disposal, environmental impact, and required recoating cycles.  Only use paint products that have been tested for MPI'S "DETAILED PERFORMANCE" or "EVALUATED PERFORMANCE ". Do not use products that have only been tested for "INTENDED USE".

f.    If an "Aggressive" environmental condition option is not available in the MPI Decision Tree for a certain substrate, use the "Normal" environmental condition option.

g.    Refer to the Additional Exterior Paint and Coating System Requirements below for further system requirements.

Paints and coatings must comply with Master Painters Institute Green Performance Standard GPS-1-12 which is available at the following website; http://www.specifygreen.com/EvrPerf/EnvironmentalPerformance.html.  Choose paints that provide performance, are environmentally friendly, and that conform to EPA or local environmental regulations, whichever requires the lowest VOC content.

B201009 1.1.1 MPI Gloss Levels

Gloss levels must comply with the MPI system of determining gloss as defined in the Evaluation sections of the MPI Manuals.  Utilize the performance characteristics of the paint gloss and sheen to categorize paint rather than manufacturers’ description of the product.  The MPI Gloss Levels are indicated by the notation G1, G2, G3, G4, G5, G6, or G7. Navy only uses MPI Gloss Levels G2, G3, G5, G6.

The MPI Decision Tree indicates a default gloss level for each paint system, however consider the appearance, anticipated conditions, and need for cleaning when establishing the final gloss level for each coated surface of the project. Comply with the following guidance in choosing the appropriate gloss level.

a.   Use G2 "Velvet-like" Flat for ceilings, residential walls away from human contact and low traffic areas.

b.   Use G3 "Eggshell-like" in high traffic areas for ceilings and walls, when human contact with the wall is limited, and for dark accent colors.

c.   Use G5 Semigloss for walls, doors and trim for high durability and clean ability and when a surface is expected to have routine human contact.

d.   Use G6 Gloss only in special situations such as for piping identification or special effects.

The MPI gloss and sheen standard values are in accordance with ASTM D523, and are as follows:

B201009 1.1.2 MPI System Designations and Table Abbreviations

2. REX - the MPI short term designation for an exterior coating system used in repainting projects or over existing coating systems.
3. DSD - the MPI short-term designation for Degree of Surface Degradation as defined in the Assessment sections in the MPI Maintenance Repainting Manual.  Degree of Surface Degradation designates the MPI Standard for description and appearance of existing condition of surfaces to be painted. This DSD classification is used to determine the proper surface preparation necessary for painting.

B201009 1.1.3 Surface Preparation

Comply with the "Exterior Surface Preparation" section of the MPI Architectural Painting Specification Manual, or the Exterior Surface Preparation” section of the MPI Maintenance Repainting Manual. All suggestive language such as "may" or "should" are deleted from the standard and "must" inserted in its place. Suggestive language such as "recommended" or "advisable" is deleted from the standard and "require" or "required" inserted in its place. The results of these wording substitutions change this document to required procedures. For surface preparation, determine a MPI DSD Assessment of each surface and comply with the MPI Surface Preparation Requirements relating to the assessments.  Not-withstanding MPI requirements, clean exterior ferrous metal that is exposed to weather conditions (wind, precipitation, solar degradation, and humidity) to a SSPC SP 10 level (near white).

Remove dirt, splinters, loose particles, grease, oil, and other foreign matter and substances deleterious to coating performance as specified for each substrate before application of paint or surface treatments.  For existing buildings, use MPI Maintenance Repainting Manual to determine the coatings that need to be removed.  Remove deteriorated or loose coatings before repainting begins.  Remove oil and grease prior to mechanical cleaning.  Program cleaning so that dust and other contaminants will not fall on wet, newly painted surfaces.  Spot-prime exposed ferrous metals such as nail heads on or in contact with surfaces to be painted with water-thinned paints with a suitable corrosion-inhibitive primer capable of preventing flash rusting and compatible with the coating specified for the adjacent areas.

NOTE:  Use film for retrofit to existing glazing when window replacement is not included in the project, when glass may be subjected to the effects of explosives or projectiles and when protection of personnel from the resulting glass spalling is required.  The film is most effective when installed on the interior surface of the glass.

Also, see Navy's User’s Guide (UG) 2030, Security Glazing Applications, and Army Corps of Engineers Engineering Technical Letter (ETL) 1110-3-501, Windows Retrofit Using Fragment Retention Film With Catcher Bar System.

The application of film to glass provides some resistance against impacts from hammers, rocks, clubs, or thrown objects.  An impact on the film-reinforced glass creates a hole approximately the size of the impacting object.  Therefore, several impacts are needed to make a hole large enough for entry.  The use of greater film thickness for retrofits and factory laminated films for new glazing provides more resistance against these impacts.

Existing windows that will not be replaced in the project must have fragment retention film if antiterrorism protection is required.  The film must be polyester, polyethylene terephthalate, or a composite.  Fragment retention film must be optically clear and free of waves, distortions, impurities, and adhesive lines.  The film may be a single layer or laminated.  Lamination of the film must only occur at the factory of the fragment retention film manufacturer.  The film must include an abrasion resistant coating on the surface that does not receive the film adhesive.  Fragment retention film must be a minimum thickness of 0.004 inch (0.1016 mm), or 0.007 inch (0.1778 mm), or 0.010 inch (0.254 mm).  The film must be supplied with an optically clear weatherable pressure sensitive adhesive.  The adhesive must contain ultraviolet inhibitors to protect the film for its required life and must limit ultraviolet transmission to not more than 8 percent of the radiation between 300 and 380 nanometers.  The adhesive must not be water activated.  A water-soluble detackifier or release liner may be incorporated over the adhesive to facilitate film application.  The adhesive must be 90 percent cured within 30 days of installation.  Adhesives on film thicknesses of 0.010 inch (0.254 mm) and greater must be a minimum of 0.0008 inch (0.02032 mm) thick.
