Using a suitable sized brush, apply a thin, even coat
of solvent cement to the internal surface of the socket
Then apply a thin even coat of solvent cement up to the
witness mark on the spigot, DO NOT USE EXCESS SOLVENT
CEMENT, and DO NOT DILUTE or add anything to
the solvent cement. As a guide the brush should be approximately
one third the pipe diameter and large enough to apply
the solvent cement to the joint in about 30 seconds.
