Are Composite Decks Capable of Being Painted?
Wisconsin homeowners frequently ask: “Can I paint my composite deck?”
No, it’s not recommended to paint a composite deck.
Contrary to wood decks which require staining or sealing every few years, composite decking such as TimberTech is designed to retain its color and finish for decades. Made from a blend of recycled wood fibers and polymers, its weatherproof surface does not absorb paint or stain easily.
That means most modern composite decks come factory-sealed with protective coatings designed to ward off moisture, fade and mold, rendering painting both unnecessary and potentially dangerous.
When Painting Could Be an Option
Painting may be considered for older composite decks that have been left without protective caps and have faded over time, particularly first-generation products without protective caps. As these older decks may fade and develop surface wear that accepts paint better, painting them could help bring them back into style and improve aesthetics. But before taking this route, it should only be done when:
- High-grade acrylic latex paint designed for composite and vinyl surfaces is available here.
- Cleaning and sanding must take place prior to application.
- A primer specifically developed for synthetics can assist with paint adhesion.
Consider that once painted, your deck will require regular maintenance, undermining any low-maintenance benefits associated with composite materials in the first place.

Refresh Instead of Repaint
Rather than painting, GM Home Improvements suggests professional cleaning, light pressure washing and applying a composite-safe brightener or rejuvenator to restore the original tone of your deck. Many modern TimberTech lines such as Legacy or Reserve, feature color-rich boards that can easily be revitalized through proper maintenance, rather than replaced or painted over.
Our Waukesha deck builders specialize in composite deck restoration and can assess whether your deck needs deep cleaning, partial replacement, or an upgrade using TimberTech’s latest capped composite boards.
