be as follows:
(a) Check surface of the seams ensuring they are clean, dry and free
from grease and oil.
(b) Each surface shall be given two coats of cement (pre-cementing)
allowing 10 minutes drying time between coats. The surfaces
shall be rechecked ensuring the pre-cementing procedure has
completely covered the cellular structure of the foam.
(c) The third and final coat of cement shall completely cover the
first two coats. Allow this coat to become tacky and press the
cemented edges together firmly. Turn to inside and press the
back side of the seam together. After pressing the seam inside
and outside, the seam shall be pinched together inside and

(b) The nylon surfaces of the suit shall be given three pre-coats of
cement . The reinforcement pieces shall be given one pre-coat of
cement applied onto the open-cell foam side of the reinforcement
piece. Allow 10 minutes drying time between coats.
(c) After the pre-cementing coats have dried, apply a final coat to
each surface. When tacky, surfaces shall be joined by rolling
with a heavy metal roller (see figure 2).
(d) After allowing sufficient time for the bond between the two sur-
faces to set, the edges of the reinforcement pieces shall be
rolled down. To achieve this, pre-cement the edges of the
reinforcement pieces and the nylon of the suit where there will
be contact. When dry, cement the surfaces and roll the edges
of the reinforcement pieces over onto the surfaces of the suit
with a heavy metal roller (see figure 2).
