AMICO EIFS Expansion Joint
(Deep “V”) for 1/4” Ground with Removable Tape
is manufactured with a deep center “V” which allows for more movement than would normally be possible with one that matched the thickness of the finish coat. This bead requires that a space be left between sheets of foam, or routed into the foam board to accommodate the deep center “V”. All surfaces that receive finish have ridges for better adhesion.

1/4” ground is typically used with some 1-coat stucco and hard coat EIFS systems.
