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 the appearance of finely painted wood.
  • A properly painted finish will last for years protecting the substrate from mold, mildew and the UV rays from the sun. AZEK surfaces must be clean, dry and void of any foreign material such as dirt, oil, grease or other contaminates 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.
