What Is Composite Decking?

Composite decking is a type of building material used for decks and other outdoor structures. It’s made from a blend of wood fibers and recycled plastics, creating a sturdy and durable material.

Composite decking mimics the look of natural wood but requires less maintenance. It’s resistant to rot, decay, and insect damage, and it doesn’t require painting, staining, or sealing.

This makes it a popular choice for homeowners who want the aesthetic appeal of wood without the extensive upkeep. Composite decking comes in various colors and styles, providing versatility for different design preferences.

Why Choose Composite Decking?

Before we delve into the installation process, let’s quickly highlight why composite decking is such a fantastic option for your outdoor space:

Durability: Composite decking is highly resistant to rot, mold, insects, and moisture, ensuring it will last for years to come.
Low Maintenance: Unlike traditional wood decking, composite decking doesn’t require staining or sealing. A simple wash with soap and water is usually all that’s needed to keep it looking pristine.
Aesthetics: Composite decking comes in a wide range of colors and textures, allowing you to choose a style that complements your home and personal taste.
Environmentally Friendly: Many composite decking brands use recycled materials, making it an eco-friendly choice for environmentally conscious homeowners.

Now that you understand why composite decking is a great option, let’s get into the installation process.

How to Install Composite Decking

Step 1: Prepare Your Tools and Materials

Before diving into the installation process, gather all the necessary tools and materials. Here’s what you’ll need:

Composite decking boards
Joists
Composite deck screws
Measuring tape
Carpenter’s pencil
Circular saw
Drill
Spacers
Level
Safety gear (gloves, safety glasses, dust mask)

Step 2: Create a Solid Foundation

A solid foundation is crucial for the longevity of your composite deck. Start by installing joists to support the decking boards. Make sure the joists are spaced at the manufacturer-recommended distance (usually 16 inches on center) to provide adequate support. Use a level to ensure the joists are level and secure them to the existing structure or posts.

Step 3: Install the Composite Decking Boards

Now it’s time to lay down the composite decking boards. Begin at one end of the deck and work your way towards the other end. Leave a small gap between the boards (usually about 1/8 inch) to allow for expansion due to temperature changes. Use spacers to maintain consistent spacing between the boards.

Secure each board in place with composite deck screws. Be sure to screw them into the joists to ensure a secure attachment. Use a circular saw to trim the last board to fit if necessary. Continue this process until the entire deck is covered.

Step 4: Finish the Edges

To give your composite deck a polished look, you’ll need to finish the edges. This can be done using composite fascia boards or trim pieces designed to match your decking. Secure these pieces in place using composite screws, ensuring they are flush with the decking surface.

Step 5: Clean and Maintain Your Deck

Once your composite decking is installed, it’s essential to perform regular maintenance to keep it looking its best. While composite decking is low maintenance, it still requires some care. Periodically clean your deck with soap and water to remove dirt and debris. Avoid using harsh chemicals or pressure washers, as these can damage the material.

FAQs for Composite Decking

Now that you have a basic understanding of how to install composite decking, let’s address some frequently asked questions to provide you with more comprehensive information.

1. How long does composite decking last?

Composite decking is known for its longevity and can last up to 25-30 years or more with proper care and maintenance. Many manufacturers offer warranties ranging from 20 to 25 years, reflecting their confidence in the product’s durability.

2. Can composite decking be painted or stained?

Most composite decking cannot be painted or stained because it is already finished with a protective layer. However, if you want to change the color of your composite deck, there are specialized composite deck paints available. Be sure to check with the manufacturer for compatibility.

3. Is composite decking resistant to fading and scratching?

Yes, one of the advantages of composite decking is its resistance to fading and scratching. Most composite deck boards are designed to maintain their color and resist scratches even in high-traffic areas.

4. Can I install composite decking over an existing deck?

The existing deck structure must be in good condition and able to support the additional weight of the composite boards. Consult with a professional to assess whether this is a viable option for your specific situation.

5. How do I clean mold and mildew off my composite deck?

Composite decking is generally resistant to mold and mildew, but it can still develop in areas with persistent moisture. To clean mold and mildew, use a composite deck cleaner recommended by the manufacturer and follow their cleaning instructions. Avoid using bleach, as it can cause discoloration.

6. How much gap should I leave between composite deck boards?

The gap varies depending on the brand and the climate. Typically, a gap of 1/8” is recommended for thermal expansion and drainage.
