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.

21
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

Framing Sheathing (by others)
Water Barrier (by others)

• Traditional stucco with a warranty
• Applied full thickness, nominal 7/8 over
  sheathing, 1/2 over masonry, 3/8 over concrete
• Like traditional stucco, but with fibers
• Two water barriers are required over sheathing
• May be applied directly to masonry or concrete
• 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

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

DEFS Design Basics

• A secondary water barrier is required for DEFS in
  vertical applications
• System breaks at penetrations
• Typically a small sealant joint is used
• Plastic trims are commonly used
• Control joints are used to minimize possible
  cracking
• 160 s.f. maximum wall area
• Placed no more than 20 lineal feet in any
  direction
• Length to width ratio no more than 2.51
• Off corners of windows/doors and at dissimilar
  substrates System breaks at penetrations
• Sealant bridges between the DEFS and wall
  penetration

30
Insulated Concrete Forms
Insulated Concrete Form (by others)

• Base coat, mesh and finish over the ICF forms
• Great if ties are buried within the insulation,
  otherwise another layer of insulation board is
  required
• Economical compared to other ICF finishing options

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
