When laying cement-joint pipe and plastic cement is used, how much mortar cream is needed?

• A. A lot
• B. Some
• C. Mortar cream is unnecessary when using plastic cement
• D. None of the above

Answer: (C)

Using plastic cement to join pipe means the bond is created by a solvent-weld between the plastic surfaces. Mortar cream is only used with cement-joint pipes to fill and seal cementitious joints. Since the joint relies on the plastic cement itself, no mortar cream is needed. Adding it would be unnecessary and could interfere with the bonding process.
