What is EIFS?
Exterior Insulation and Finish SystemAlso called: Synthetic Stucco
EIFS is a System
1. Sheathing
2. Secondary Barrier
3. Joint Reinforcement
4. Drainage Mat/Lath
5. Adhesive / Base Coat
6. Insulation Board
7. Mesh
8. Finish Coat / Texture
9. Mechanical Fastener
What type of EIFS?
Barrier Drainable Panelized Pressurized Direct Applied
Barrier vs Drainable Walls
Barrier System Drainable System
Drainable Systems
Barrier Systems
1. Substrate
2. Joint Treatment
3. Weather Barrier
4. Cementitious Adhesive
5. EPS Board (Foam)
6. Base Coat
7. Mesh
8. Finish

Any Penetrations
When are we most important?
Design Phase? Submittal Review? Ongoing
Inspections?
Product Selection? Pre-Con Briefings? Repair Reviews? Client Education?

Poor Fit = More Work!
Educate the Trades
When the EIFS is Finished
Protect
Repair
Monitor other trades
Penetrations – The Good
Penetrations sized for repairs and proper sealant joints
Penetrations – Not-so-Good
No allowance for mesh repair or a sealant joint.
Check the Specs
Sad Painful Truth
Specifications and Instructions are rarely available in the field.
Inspecting Existing EIFS
Bulges or Cracks in Finish Sealant Joints around doors, windows other
penetrations Staining or discolored finish around joints Does the EIFS contact the ground or
hardscape? Where EIFS and roof lines come together
Sealant Joints Flashing
What to watch for - Cracks
What to watch for - Flashing
What to watch for - Damage
What to watch for - Damage
What to watch for - Damage
What to watch for - Substrate
Proper substrate on non-vertical surfaces
Incorrect Correct
What to watch for - Substrate
Poor Fastening Delaminating
Contamination
What to watch for – EPS Foam
Proper Adhesive Pattern Interlocking Corners
What to watch for – EPS Foam
Correct Incorrect
No gaps should exist in the EPS when the
base and mesh is applied!
EPS is Thermally Stable
The cementitious adhesive expands and contracts with temperature changes.
What to watch for – Base Coat
Too
thick.
What to watch for – Base Coat
Too
thin.
What to watch for – Base Coat
Damage
To
Mesh.
What to watch for – Finish
Finish coat has not adhered to the base coat.
Why? Application? Product Failure? Environmental Condition?
What to watch for – Finish
Finish application issues.
What to watch for – Sealant Joints
Creative installation of backer rod.
Sealant is too thin.
Backer rod is too shallow.
