  • Rinse the pipes thoroughly with clean water and allow them to dry completely.

Remember, a clean surface is crucial for any PVC pipe paint finish to look its best and last long.

Sanding Techniques to Improve Paint Adhesion

Sanding PVC pipes creates a slightly roughened surface that gives paint something to grip onto. This step is especially important when dealing with glossy or very smooth pipes. Here’s how to sand PVC pipes effectively:

  • Use fine-grit sandpaper (around 220-grit) to lightly scuff the entire surface of the pipe.
  • Sand in a circular motion to create an even texture across the pipe.
  • After sanding, wipe away all dust with a tack cloth or slightly damp rag.
  • Allow the pipe to dry completely before moving on to priming or painting.

This process helps create a surface that’s more receptive to paint, enhancing the durability of your PVC pipe coating.

Applying Primer: When and Why It’s Necessary

While not always required, using a primer can significantly improve paint adhesion and longevity, especially for outdoor applications or when using lighter colors. Here’s what you need to know about priming PVC pipes:
