How to Install Laminated PVC Outdoor Decking: A Step-by-Step Guide
June 11, 2025

Outdoor decking enhances the beauty and functionality of your outdoor space. Among the various decking materials available, laminated PVC panels are gaining popularity due to their durability, low maintenance, and aesthetic appeal. In this blog, well walk you through the installation process of laminated PVC decking and compare it with WPC (Wood-Plastic Composite) panels and traditional wood panels.  

 

Step-by-Step Installation of Laminated PVC Outdoor Decking  

 

Tools & Materials Needed:

Laminated PVC decking panels  

Joists (aluminum or pressure-treated wood)  

Hidden or surface fasteners  

Measuring tape, level, and chalk line  

Drill and screws  

Rubber mallet (for click-lock systems)  

Spacers for expansion gaps  

Saw (for cutting panels)  

 

Installation Steps:

Prepare the Subframe

Ensure the ground is level and well-drained.  

Install joists (aluminum is best for PVC decking) for optimal support.  

Use a slope of 1-2% for water drainage if needed.  

 

Lay the First Row of PVC Decking  

Start from one corner, leaving a 1/4-inch gap from walls or fixed structures for expansion.  

Secure the first board using starter clips or hidden fasteners for a clean look.  

 

Continue Installing Panels

For click-lock systems, align the tongue-and-groove edges and gently tap with a rubber mallet.  

For grooved-edge systems, use hidden fasteners screwed into the joists.  

Maintain consistent gaps (3-5mm) between boards for expansion.  

 

Cut and Fit Edge Pieces

Measure and cut panels as needed using a fine-tooth saw.  

Secure the final row with appropriate fasteners.  

 

Install Edge Trims & Finishing Touches  

Add edge trims for a polished look.  

Clean the deck surface to remove debris.
