Covering a concrete deck? Yes, it’s possible and here’s how!

The benefits of using a PVC subfloor on a concrete slab

There’s no point in trying to cut corners. When it comes to covering a concrete deck, it’s absolutely essential to cover the surface with a cellular PVC subfloor first.

If you install synthetic decking directly on top of a concrete surface, you’ll be running a big risk. You’ll be creating a perfect environment for mold and mildew between the slab and the new deck boards. The purpose of the cellular PVC subfloor is to create a chamber of air between the synthetic deck board covering and the concrete slab. This will prevent the accumulation of moisture that can lead to mold.

The numerous protective barriers of a PVC subfloor

The PVC structure will protect your new decking from the cold and moisture emanating from the concrete slab. With this technique, there will be less of a risk of condensation once the air on the surface becomes warm and humid.

This incredible cellular PVC subfloor offers other advantages, as well. Among other things, it allows you to take an unstable or uneven surface and make it perfectly solid and flat.

The ease of installation of a PVC subfloor

When the time comes to install your cellular PVC subfloor, you’ll begin by placing the PVC pieces around the perimeter of the deck. Next, you’ll lay the other pieces lengthwise inside the perimeter, starting in the center and spacing them 16 inches (40 cm) apart. Before nailing, it’s important to make sure that the decking is sloped at the correct angle to allow water to drain off the deck.

The orientation of your PVC subfloor will be determined by the desired orientation of the final covering. The PVC pieces must be perpendicular to the deck boards.

Once the PVC structure is successfully installed, you can begin installing your decking. It’s as simple as that!
