Product Care

Azek products must be painted prior to being installed or they will discolor and void the warranty.

The following is recommended:

  • Azek doesn't have a finish and that leaves the material subject to dirt, smudges, mold, and mildew.

  • Properly prepared and painted with even brush strokes gives it the appearance of finely painted wood.

  • A properly painted finish will last for years, protecting the substrate from mold, mildew and UV rays.

  • Surfaces must be clean, dry and void of any foreign material such as dirt, oil, grease or other contaminants that may come from normal handling, storage and/or installation prior to painting.

  • Use a 100% acrylic latex paint with colors having a Light Reflective Value (LRV) of 55 or higher.
