Can I use DuPont™ Tyvek® HomeWrap® under stucco?
DuPont™ Tyvek® StuccoWrap® is recommended under stucco because it has been specially designed to work with both traditional and synthetic stucco applications. The engineered surface with special grooves is designed to assist in drainage of incidental moisture that may penetrate the primary cladding in synthetic stucco systems. DuPont™ Tyvek® HomeWrap® will also provide the weather barrier characteristics in an EIFS wall system, but its drainage properties will differ. Therefore, in synthetic EIFS stucco systems, DuPont™ Tyvek® HomeWrap® can be used as the secondary weather barrier but in conjunction with an additional drainage medium (either matte or grooved foam) to achieve the desired drainage characteristics.
