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

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.
