Its purpose is to remove any dirt, debris, or grease and to soften the PVC, ensuring optimal adhesion.
To effectively use a PVC primer, start by cleaning the surface of the PVC pipe and fitting using a cloth or sandpaper. This step is important to remove any existing debris that may hinder the bonding process. Once the surface is clean, generously apply the primer using a brush or applicator. Make sure to cover the entire surface area to maximize its effectiveness.
After applying the PVC primer, it is crucial to allow it to dry completely. Typically, this process takes only a few minutes. However, it is important to wait for it to dry before proceeding with the next steps. This will ensure that the primer has fully worked and optimized the PVC surface for bonding.
Cement
PVC cement, specifically PVC cement, plays a critical role in repairing broken PVC pipes embedded in concrete. It is specifically designed to create a strong bond between PVC pipes and fittings, ensuring a secure and leak-free connection.
To effectively use PVC cement, follow these steps:
- Apply a thin layer of cement to both the inside of the PVC repair coupling and the outside of the existing PVC pipe.
- Ensure even coverage by applying the cement in a circular motion.
- Insert the repair coupling onto the existing pipe, twisting it slightly to ensure a tight fit.
- Hold the pieces together for a few seconds to allow the cement to bond properly.
