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.  Designate in the project program that EIFS shall be used as the non-primary or the primary exterior finish material for the project.  The exterior insulation and finish system (EIFS) shall be a job-fabricated exterior wall covering consisting of sheathing, moisture drainable insulation board system, reinforcing fabric, base coat, finish coat, adhesive, primer, accessories, flashing, sealant, and mechanical fasteners.  The system components shall 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.  All materials shall be installed by an applicator trained and approved by the system manufacturer in accordance with DOR-approved shop drawings and manufacturer’s recommendations. EIFS shall be Class PB or Class PM.  Class PB EIFS shall not be used 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 shall 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.  Warranty shall run directly to Government and cover a period of not less than 5 years from date Government accepted the work.

B201001 1.4.1 EIFS System Components

1. Glass Mat Gypsum Sheathing Board - Conform to ASTM C 1177/C 1177M.  Nail Pull Resistance: No less than 120 lb (54.4 Kg) when tested in accordance with ASTM C 473.
2. Mechanical Fasteners - Corrosion resistant and as approved by EIFS manufacturer.  Select fastener type and pattern based on applicable wind loads and substrate into which fastener will be attached, to provide the necessary pull-out, tensile, and shear strengths.
3. Thermal Insulation - Drainable type.  No portion of any layer of insulation shall be less than 3/4 in (19 mm) thick.  The maximum thickness of all layers shall not exceed 4 in (101 mm). Insulation Board shall be certified as aged, in block form, prior to cutting and shipping, a minimum of 6 weeks by air-drying, or equivalent. Insulating material shall conform to ASTM C 578, Type I or IV, as recommended by the EIFS manufacturer and treated to be compatible with other EIFS components.
4. Reinforcing Fabric - Reinforcing fabric mesh shall be alkali-resistant, balanced, open weave, glass fiber fabric made from twisted multi-end strands specifically treated for compatibility with the other system materials, and comply with EIMA TM 105.01 and as recommended by EIFS manufacturer.

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.  Oil and grease shall be removed prior to mechanical cleaning.  Cleaning shall be programmed so that dust and other contaminants will not fall on wet, newly painted surfaces.  Exposed ferrous metals such as nail heads on or in contact with surfaces to be painted with water-thinned paints, shall be spot-primed with a suitable corrosion-inhibitive primer capable of preventing flash rusting and compatible with the coating specified for the adjacent areas.

B201009 1.1.1 MPI Gloss Levels

Gloss levels shall 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.  Use G2 "Velvet-like” flat for vertical surfaces and undersides of balconies and soffits.  Use G3 "Eggshell-like" in high "traffic areas for ceilings and walls, when a surface can be touched and a slightly more durable finish is desired, and for dark accent colors. Use G5 Semigloss for ceilings, walls, doors and trim for high durability and cleanability.  Use G6 Gloss only in special situations such as for exterior wood and metal, piping identification, or special effects.  The MPI gloss and sheen standard values are per ASTM D523, method D and are as follows:

Gloss Level Number             Gloss@60 Degrees  Sheen@85 Degrees
Gloss Level 1(G1)–Matte or
     Flat                      Max.5 units       Max.10 units
Gloss Level 2(G2)–"Velvet-like"
     Flat                      Max. 10 units     10-35 units
Gloss Level 3(G3)–"Eggshell-
     like"                     Max. 10-25 units  10-35 units
Gloss Level 4(G4)-"Satin-like  Max. 20-35 units  Min. 35 units
Gloss Level 5(G5)-Semi-Gloss   35-70 units
Gloss Level 6(G6)–Gloss        70-85 units
Gloss Level 7(G7)–High Gloss   More than 85 units

B201009 1.1.2 MPI System Designations and Table Abbreviations

The MPI coating system number description is found in either the MPI Architectural Painting Specification Manual or the Maintenance Repainting Manual and defined as an exterior system

1. EXT - MPI short-term designation for an exterior coating system on a new surface.
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.
4. DFT – The short-term designation for dry film thickness. DFT is the minimum acceptable depth or thickness of a coating or system in the dry state.  The maximum acceptable DFT is not more than 50% greater than the minimum acceptable DFT (example... DFT = 2 mils, maximum DFT = 3 mils). The DFT indicated in the paint systems below relate to new coatings - MPI INT. MPI RIN will be less than the indicated DFT.
5. Paint Systems Abbreviations: BF – block filler; C – clear coat; SP – spot primer ;P – primer coat; I – intermediate coat; T – topcoat; .
   

B201009 1.1.3 Surface Preparation
