Can Trenton #2 tape be used below ground?
#2 Trenton can be used underground in the same manner as #1 is used with the correct primer. The correct primer is called Temcoat, and is similar to the primers normally used. It is a little thicker/heavier but application is the same—a thin layer worked into the wall of the pipe. It is good to use with cathodic protection on the line and allows a one tape system (#2 and Temcoat) to be used at the ground interface rather than the old two tape system of #1 next to the pipe with #2 on top of the #1.
