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.
