Clean the threads of the pipe that you are connecting. Use a wire brush or steel wool, along with cleaning solvent or rust remover as necessary, to remove any rust, scale or grease from metal pipe threads.
Wipe the threads with a clean cloth to remove remaining debris. Use detergent or solvent to clean and prepare greasy or dirty plastic or fiberglass pipes and then wipe with a clean cloth.
Open the metal package of Great White pipe joint compound and stir it with the brush attached to the inside of the cap or any convenient stirring rod.
Apply the compound to the male threads of the pipe (the threads onto which you will fasten a connector) evenly, using the brush inside the cap.
Connect the joint, flange or other connector to the treated threads, and tighten with appropriate tools as recommended for the type of pipe you are using.
Use a clean cloth to wipe off any excess Great White that may appear at the edges of the connection.
Repeat for all joints and connections; make sure to treat all male threads of all pipes that you are repairing or replacing with Great White pipe joint compound.
