Decking refers to the flat surfaces that make outdoor spaces enjoyable and livable. Typically made from composite materials like Trex—an alternative to traditional wood—decking lasts over 25 years and resists rotting and insect damage.

Before You Start Painting Trex Decking

What do you need to get started?

  • Deck Cleaner: Use a cleaner like Krud Kutter Deck Wash. It removes dirt and mildew, ensuring the paint adheres properly.
  • Painter’s Tape: Get high-quality tape such as ScotchBlue. It protects areas you don’t want painted, creating crisp, clean lines.
  • Brushes and Rollers: Use a high-density foam roller like Purdy Whale Mini Roller. This tool provides an even finish on textured surfaces like Trex.
  • Primer: Buy an exterior-grade bonding primer like Zinsser Covers Up. It’s essential for making the paint stick to the decking surface.

Steps to Effectively Paint Trex Decking

Follow these steps to paint your Trex decking without compromising its integrity.

  1. Prepare the Surface

    Start by cleaning your Trex decking with a pressure washer set to 2000 psi. This will remove dirt, mildew, and grime. Allow the deck to dry completely—ideally wait 24 hours for moisture to evaporate.

    Next, inspect for scratches or damage. Use 60-grit sandpaper to lightly sand areas where you’ll apply paint, focusing on rough spots for a smooth finish.

  2. Apply Primer to Trex Decking

    Select a high-quality, latex and acrylic-based primer for the best results. Apply at least two coats to bare or patched areas, waiting about 2 hours between coats to dry.

    Cover all corners and edges thoroughly to ensure good adhesion for the paint. The primer needs a minimum dry time of 24 hours before painting.

  3. Choose the Right Paint

    Choose paint designed for composite and plastic materials, suitable for Trex decking. An acrylic paint is a great choice because it offers UV protection and resists fading.

    Look for options with a lifespan of 7-10 years, as indicated by the manufacturer. Ensure the paint is labeled for outdoor use.

  4. Painting the Decking

    Now it’s time to paint! Use rollers or paint pads for large sections and a brush for detailed areas. Applying in small sections helps manage drips and ensures an even coat.

    Apply two thin layers of paint, waiting 24 hours between applications for proper curing. Consider tapering off the edges during the second layer for a sharp finish.

That covers the suggested color options for painting Trex decking. Let’s now take a look at suitable paint types for Trex decking.

Types Of Paint Suitable for Trex Decking

Let’s discuss the types of paint: Latex Paint, Acrylic Paint, Oil-Based Paint, and Stain.

  • Latex Paint

    Latex paint is water-based, making it easy to clean and quick to dry. For Trex decking, it’s flexible and generally holds up well against UV rays, lasting up to 10 years when properly applied.

  • Acrylic Paint

    Acrylic paint offers excellent adhesion (Sticking) on composite materials like Trex. This type is breathable and resists fading, helping it look fresh for 7-10 years on average.

  • Oil-based Paint

    Oil-based paint provides a hard finish that’s highly durable. However, it can take longer to dry and may not adhere perfectly to Trex, often lasting only 3-5 years.

  • Stain

    Stain penetrates the wood grain, making it ideal for Trex’s texture and promoting humidity resistance. A solid stain can last 5-8 years, while semi-transparent stains need reapplication about every 2 years.

From my experience, acrylic paint strikes the best balance between durability and ease of application for composite decks like Trex. Its resistance to UV light helps keep the deck vibrant over time. If you’re considering mixing paint types, you might want to explore paint compatibility techniques.

We’ve wrapped up the types of paint suitable for Trex decking here. Let us turn our attention to factors influencing the painting decision.
