Why Choose WPC Click Decking?

Before we dive into the building process, let's talk about why WPC Click Decking is a fantastic option for your floating deck. WPC stands for Wood - Plastic Composite, which means it combines the natural look of wood with the durability and low - maintenance benefits of plastic.

One of the biggest advantages of WPC Click Decking is its ease of installation. The click - together system eliminates the need for nails or screws in most cases, making the installation process faster and more straightforward. It's also resistant to rot, insects, and moisture, so you won't have to worry about costly repairs or replacements down the line.

Another great thing about WPC Click Decking is its aesthetic appeal. It comes in a variety of colors and textures that can mimic the look of real wood, allowing you to create a deck that matches your personal style and the overall design of your home.

Step 1: Planning Your Floating Deck

The first step in building a floating deck is planning. You need to determine the size and shape of your deck based on the available space in your backyard and how you plan to use it. Consider factors like seating areas, dining spaces, or even a small hot - tub if you're feeling fancy.

Measure the area where you want to build the deck. Make sure to account for any slopes or uneven ground. A floating deck doesn't need to be attached to your house, but it should be level. You can use a string line and a level to mark the perimeter of your deck.

Step 2: Gathering Materials and Tools

As a WPC Click Decking supplier, I can help you source all the necessary materials. You'll need WPC Click Decking boards, which you can find in different lengths and widths. Check out Deck Modular WPC for some great options. You'll also need joists, which are the horizontal beams that support the decking boards. Pressure - treated lumber works well for joists.

For tools, you'll need a tape measure, a circular saw, a drill, a level, a hammer, and safety equipment like gloves and goggles.

Step 3: Preparing the Site

Once you've planned your deck and gathered your materials, it's time to prepare the site. Clear the area of any grass, rocks, or debris. If the ground is uneven, you may need to dig out some soil or add gravel to create a level base.

Lay down a weed barrier fabric over the prepared area. This will prevent weeds from growing up through your deck and keep your deck looking clean.

Step 4: Installing the Joists

The next step is to install the joists. Start by placing the joists on the prepared site, spacing them evenly according to the manufacturer's recommendations. Usually, joists are spaced 16 inches on center.

Use joist hangers to attach the joists to each other and to any support posts if you're using them. Make sure the joists are level using a level. You can shim them with small pieces of wood if necessary.

Step 5: Installing the WPC Click Decking

Now comes the fun part - installing the WPC Click Decking! Start at one corner of the deck and lay the first board down. Make sure it's straight and aligned with the edge of the joists.

The click - together system of the WPC Click Decking makes installation a breeze. Simply align the tongue of one board with the groove of the next board and click them together. Use a rubber mallet to gently tap the boards into place if needed.

As you work your way across the deck, cut the boards to fit using a circular saw. Leave a small gap between the boards for expansion and contraction. This gap will also allow water to drain off the deck.

Step 6: Finishing Touches

Once you've installed all the decking boards, it's time to add the finishing touches. You can install deck railing for safety and aesthetics. You can also add stairs if your deck is elevated.
