Fast-Acting Surface Preparation
PRIMER-68 is formulated to quickly penetrate and soften compatible PVC and CPVC pipe and fitting surfaces, providing the preparation needed before the appropriate solvent cement is applied.
Proper priming is an important part of solvent-cement joining because it prepares the mating surfaces for bonding while helping installers achieve consistent preparation across the pipe and fitting connection.
PVC & CPVC Compatibility
PRIMER-68 is suitable for all types, classes, and schedules of compatible PVC and CPVC pipe and fittings, making it a versatile primer for many plumbing, industrial, irrigation, and other solvent-weld piping applications.
The correct Spears® solvent cement should be selected separately according to the piping material, nominal size, schedule, service conditions, and requirements of the intended system.
Clear & Purple Options
PRIMER-68 is produced in clear and purple formulations. Purple provides visible identification that primer has been applied, while clear can be selected where a less visible finished appearance is desired and local requirements permit its use.
Because plumbing and installation requirements can vary, always verify whether a specific primer color or visible primer identification is required by the applicable local code before beginning the installation.
Preparation Before Solvent Cement
PRIMER-68 is a surface-preparation product and does not replace solvent cement. After the PVC or CPVC surfaces have been properly primed, the appropriate compatible solvent cement must be applied according to the required joining procedure.
Keep the container tightly sealed between uses because solvent evaporation can affect product usability, and never add solvents or other materials to the primer in an attempt to change its consistency.
Installation & Selection Considerations
- Use with PVC or CPVC.
- Keep the container tightly sealed.
- Confirm local primer color requirements.
- Apply primer to the required bonding surfaces.
- Follow with the appropriate PVC or CPVC solvent cement.
