What Glue to Use on Composite Decking

Introduction

Composite decking has become increasingly popular due to its low maintenance and long-lasting qualities. However, like any other material, it may require repairs over time. When it comes to fixing composite decking, choosing the right adhesive is crucial for ensuring that your repairs last and maintain the integrity of your deck. This article will detail the process of selecting an appropriate adhesive for composite decking repairs, highlighting key properties to look for and mentioning popular brands and their specific applications.

Key Properties to Look For in a Glue

When repairing composite decking, it’s essential to consider several properties of the adhesive you choose. These include UV resistance, flexibility, and durability. UV resistance is particularly important because it ensures that the glue will not degrade when exposed to sunlight, which can cause discoloration and weakening of the bond. Flexibility is another critical factor since it allows the glue to accommodate the natural expansion and contraction of composite materials caused by temperature changes. Lastly, durability is vital to ensure that the repaired area remains strong and stable over time.

Popular Brands and Their Applications

Several brands offer adhesives specifically designed for composite decking. One such brand is Gorilla Glue, known for its strength and versatility. Gorilla Glue offers a wood glue that is suitable for composite materials and provides excellent bonding strength and flexibility. Another popular choice is 3M, with their Scotch-Weld Epoxy Adhesive DP8010NS being a reliable option for more demanding repairs. This adhesive is known for its high shear and peel strength, making it ideal for areas that experience heavy foot traffic or weather exposure.

Tips for Selecting the Right Glue

When selecting an adhesive for composite decking, it’s also helpful to consider the specific application. For minor repairs or small gaps, a flexible epoxy or polyurethane-based adhesive might be sufficient. However, for larger repairs or structural components, a two-part epoxy or a specialized composite repair kit may be necessary. Additionally, always read the manufacturer’s instructions carefully to ensure proper application and curing times.

Conclusion

Choosing the right glue for composite decking repairs is essential for maintaining the longevity and appearance of your deck. By considering key properties such as UV resistance, flexibility, and durability, and opting for reputable brands like Gorilla Glue or 3M, you can ensure that your repairs are both effective and long-lasting. Always follow the manufacturer’s guidelines for best results and consult professional advice if needed.
