EIFS/acrylic stucco: water, drainage and repairs

Treat EIFS as a complete water-resistive barrier, insulation, base-coat, mesh, finish and drainage assembly.

Important: this tool helps decide what to verify; it does not replace calculations, permits or professional design where required.

VERT / GREEN

Inspect cracks, joints and impact areas without puncturing the assembly.

JAUNE / YELLOW

A crack or failed joint near an opening can admit water to the substrate; repair must preserve the evaluated system.

ROUGE / RED

Soft substrate, moisture behind cladding, delamination or unknown system: intrusive investigation requires professional planning.
