Composite Deck Protector


Composite Deck Protector is a ready-to-use, water-based protective treatment for composite decks. It’s specially designed to bring water and stain repellency to composite decks without changing the decks’ color, texture or appearance. Treated decks resist penetration by water, oil, grease and other contaminants, making it easier to keep decks clean and attractive. The cured sealant also resists mold and mildew stains.
  • Resists oil, water, food, mold and mildew staining.
  • Low odor.
  • “Breathable” — treatment doesn’t trap moisture.
  • Excellent surface beading.
  • Complies with all known national, state and district AIM VOC regulations.
  • Surface and air temperatures should not exceed 90°F (32°C) at the time of application. Avoid application on hot, windy days.
  • Not recommended for use on food-contact surfaces.
