    according to their respective building types
  • Commercial Systems (IBC)
  • Residential Systems (IRC)

7
International Building Code (IBC, 2000)
  • Chapter 14 Exterior Walls
  • Applies to most Weather Coverings such as
    veneers, hardboard/wood, stone and EIFS
  • Chapter 25 Gypsum Board Plaster
  • Applies to stucco

8
IBC Chapter 14
  • Requires a weather barrier behind ALL claddings
    except
  • Over concrete or masonry walls
  • Over a wall cladding that demonstrates
    wind-driven rain resistance including joints,
    penetrations and intersections

Source IBC 2000, 1403.2

EIFS Design Basics
  • A secondary water barrier is required for
    residential construction, optional for light
    commercial (depends on codes)
  • System breaks at penetrations
  • ½ to ¾ wide sealant joints are the norm,
    fillet-type sealant joints are allowed in
    residential construction
  • Sealant bridges between the EIFS and wall
    penetrations
  • Plastic trims or backwrapping may be used where
    the system ends
  • Insulation thickness varies from ¾ to 1 minimum
    to a maximum 4 as allowed by code (5/8 to 2
    for Class PI Systems)
  • Insulation Board keeps inside wall temperatures
    more consistent.

Stucco
  • One Coat Cemplaster

22
One Coat Stucco (OCS)
Framing Sheathing (by others)
Water Barrier (by others)
  • Like traditional stucco, but with fibers
  • Installed thinner than regular stucco, ½ is
    typical
  • Typically 2-water barriers are required over
    sheathing
  • May be applied directly to masonry or concrete
  • May not be available in all areas (needs a code
    report)
  • Control joints and casing beads are required
    located by A/E
  • Generally limited to relatively flat walls some
    decorative foam trim can be added
  • Acrylic finishes commonly used as a finish coat

24
Stucco/OCS Design Basics
  • A secondary water barrier is required for
    sheathing applications
  • System breaks at penetrations
  • Very little guidelines are available. Sometimes
    the stucco is run tight to penetrations, other
    times a small sealant joint is used
  • Plastic, galvanized or zinc trims are used, sized
    for the stucco thickness (ground)
  • Control joints are used to help reduce cracking
  • 144 s.f. maximum wall area
  • Length to width ratio no more than 2.51
  • Off corners of windows/doors and at dissimilar
    substrates
  • Avoid layouts that form unusual shapes (L, U, T)

25
DEFS
  • Direct-Applied Exterior Finish System

26
Drainage DEFS
  • Direct-applied Exterior Finish System over an
    approved substrate and a weather-resistive
    barrier in vertical applications
  • Economical, easy to apply
  • Limited to southern use on vertical walls (below
    4000 Heating Degree Days)
  • DEFS typically is suitable for limited vertical
    applications

Specialty Products Best Uses
Use em where you need em
33
Elastomeric Textured Finishes
  • Elastomeric finishes use a softer acrylic polymer
  • Designed to bridge minor cracking especially in
    stucco
  • Factory mixed upgrade

34
Silicone Finish Additive
  • Silicone is factory added to a finish
  • Good for high humidity/moisture laden areas
  • Keeps the finish looking cleaner, especially for
    dirty environments
  • Does eventually leach out
  • Not for dark colors

35
Excel Mildew Finish Additive
  • All finishes are tested for minimum mildew
    resistance
  • Excel booster is factory added to exceed these
    requirements
  • Great for areas that receive minimal sunlight or
    air movement

36
Mesh Upgrades for EIFS
  • Many different mesh weights are available
    depending upon the needs
  • Generally, the higher the mesh weight the better
    the impact resistance
  • 2-layer systems offer the best impact resistance
  • Impact resistance varies from Medium to Ultra
    High
  • Detail mesh is soft and pliable for backwrapping
    or special details

37
FM Plus High Build Base Coat
  • High Build base coats help level walls
  • May be used in EIFS
  • Especially useful in DEFS or Uninsulated
    applications where out of plane conditions exist
  • May also be used to level stucco

38
Guardian Waterproof Base Coat
  • Uses waterproof acrylics
  • Good for below grade applications, long sloped
    applications
  • May be used to adhere insulation boards as well

39
Stucco Ad-Liquid
  • Greatly improve the performance of stucco
  • Increased Compressive Strength
  • Increased Tensile Strength
  • Can eliminate fogging if levels are high enough

40
Primecoat Primer
  • Primecoat equalizes finish absorption and evens
    out finish color
  • Suggested over stucco applications where
    absorption varies considerably
  • Useful over EIFS base coats where a very light
    finish color is desired
  • Highly recommended when foam trims are added to
    stucco

41
Roller-flex
  • Typically the same as the finish, minus the
    aggregate
  • Used for color changes or accent banding

42
Stone Finishes
  • Superior Stone and Aggrestone are used to create
    the look of marble or granite
  • Manufacturers offer a variety of colors and
    aggregate sizes
  • Primer required

43
Vintique Antiquing Accent
  • Highly stylized accents
  • Vary texture technique
  • Spray
  • Sponge
  • Light Spray Accent
