Do the same to the inside of the fittings. If the pipe is so hot the primer evaporates or if the pipe is above 90F, move it to a shaded area before priming the surfaces. Use notched boards to keep the pipe ends out of the dirt. Clean the pipe ends before cement application.

Dip a brush in cement and apply it to the entire active surface of the pipe to a width slightly more than the depth of the socket of the fitting, as shown in view C, figure 3-27. Then brush a light coating in the depth of the socket. (Avoid excess cement to eliminate the buildup inside the fitting when the pipe is socketed.) Apply the second coating of cement to the end of the pipe to ensure no voids exist. (There should be no problem of too much cement on the pipe because the
