Can You Glue Composite Decking Together?

Introduction

Composite decking has become a popular choice for outdoor living spaces due to its durability, low maintenance, and aesthetic appeal. However, one common question that arises is whether composite decking can be glued together effectively. This article delves into this topic, discussing the pros and cons of using glue, recommending specific adhesives, and providing step-by-step instructions on how to glue composite decking boards.

The Pros and Cons of Using Glue

Gluing composite decking boards can offer certain advantages, such as enhanced stability and reduced noise from foot traffic. However, it also comes with potential drawbacks, including the risk of damaging the deck surface during application and the difficulty in replacing individual boards if needed.

Recommended Adhesives

When choosing an adhesive for composite decking, it’s crucial to select a product specifically designed for composite materials. One recommended option is Loctite PL320 Professional Grade Epoxy Adhesive, known for its strength and flexibility. Another suitable choice is Sika Spectra Professional Epoxy Adhesive, which offers excellent bonding properties and resistance to weathering.

Step-by-Step Instructions

Here are the steps to effectively glue composite decking boards:

1. Prepare the Surface: Clean the surfaces thoroughly with a degreaser to ensure proper adhesion.
2. Apply the Adhesive: Use a notched trowel or caulk gun to apply the epoxy adhesive evenly along the edges where the boards will meet.
3. Join the Boards: Align the boards carefully and press them firmly together, ensuring no air bubbles are trapped.
4. Cure the Adhesive: Allow sufficient time for the adhesive to cure according to the manufacturer’s instructions—typically 24 hours.

Conclusion

While gluing composite decking boards can enhance their stability and appearance, it requires careful consideration and proper technique. By selecting the right adhesive and following these guidelines, you can achieve a strong bond that will withstand the elements. Remember, always refer to the manufacturer’s instructions and consider consulting a professional if unsure about the process.
