Cement Layers must be without voids and sufficient to
fill any gap in the joints.
HANDLING OF PRIMER AND CEMENT
NOTE: Observe the “use prior to” date. Cement has a limited
shelf life. Do not permit solvent cement cans to stand open. Do
not use cement that has dried to the point where it becomes
lumpy and stringy. Dispose of properly. Do not attempt to thin
out sluggish cement with thinner or primer. The solvents in
the primer and cement are highly flammable, like a fast drying
lacquer, and should not be used near an open flame. Use them
in a well ventilated area and avoid prolonged breathing of
the fumes. Prolonged contact with the skin could cause minor
irritation.
JOINING
1. Immediately upon
finishing cement
application and
before it starts to
set, insert the pipe/
tube to the full
socket depth while
rotating the pipe or fitting a 1/4 turn to insure
complete and even distribution of the cement. Hold
joint together for a minimum of 10 to 15 seconds to
make sure that pipe/tube does not move or back out of
the socket.
2. For pipe sizes 6"
and larger, a join-
ing crew consist-
ing of two persons
is recommended
and the following
additional steps
necessary:
a. Rotation of the pipe in the fitting may be omitted.
b. Hold joint together for 1 to 3 minutes depending on
pipe size.
c. As an aid for joining in these larger sizes it is rec-
ommended that a come-along or pipe joining tool
similar to that manufactured by Reed Manufacturing
Company be used.

EXCESS CEMENT
Immediately after joining and before joint is set, gently place it
back onto a level surface, wipe off all excess cement from the
circumference of the pipe and fitting.
JOINT INTEGRITY
ABS, PVC, and CPVC-CTS piping joint integrity depends greatly
upon following exactly and by intent NIBCO’s specific handling,
inspection, storage, shipping, fabrication, installation, testing,
and operating instructions. Joint integrity also depends greatly
upon an infinitely wide, unpredictable, and uncontrollable set
of product and environmental conditions that go into determin-
ing the length of drying times, before a joint should be moved,
handled, or whether intended for low or high working-pressure
applications. These conditions include size of pipe, surface
temperature of the joint, dry joint interference fit, and rela-
tive humidity. Drying times will be faster with smaller pipe/
tube, higher surface temperatures, tighter interference fits,
and lower relative humidity. Drying times will be slower when
these conditions are reversed.
Because of the uncontrollable and unpredictable variety of
drying conditions that can exist from job-to-job and moment-
to-moment, NIBCO recommends only the drying times and
solvent-welding conditions specified below:
1. When exposed to direct sunlight, solvent-welding join-
ing should not be done in atmospheric temperatures
below 40°F or above 90°F.
2. NIBCO recommends that 24 hours of joint drying time
should elapse for all sizes of pipe and drying tempera-
tures, before the joint is moved or subjected to any
appreciable internal or external pressure.
HANDLING
During the initial setting of the cement, which begins about
two minutes after application, (on small sizes) be careful not
to move or disturb the joint. NIBCO offers, as a non-liability
supplier, the following drying times as a guide in aiding the
installer, engineer, owner, or other decision making party in
deciding at his own risk when the joints are sufficiently dry
for movement, handling, low pressure, initial joint testing,
application of high pressure tests, and introduction of working
pressure. These drying times are based upon a combination of
past field experience and laboratory tests.
