Composite decking has gained immense popularity as a low-maintenance and durable alternative to traditional wooden decking. Made from a combination of recycled wood fibers and plastic, composite decking offers several advantages such as resistance to rot, fading, and warping. Many homeowners wonder whether they can plane composite decking to achieve a smoother and more even surface. In this article, we will explore the possibilities and limitations of planing composite decking.
Understanding Planing
Planing is the process of removing thin layers of material from the surface of a board to create a smoother and more uniform finish. Traditionally, planing was commonly performed on wooden boards to eliminate any imperfections or unevenness. However, planing composite decking differs from wooden decking due to its unique composition.
Composite Decking and Planing
While it is technically possible to plane composite decking, it is generally not recommended. Unlike wood, composite decking consists of a combination of wood fibers and plastic, which present challenges when it comes to planing. The plastic component in composite decking can melt or warp when subjected to the heat generated by the planing process. Additionally, the wood fibers in the composite decking can splinter or break, leading to an uneven and potentially unstable surface.
Risk of Damaging the Decking Material
Planing composite decking can lead to irreparable damage to the material. The heat generated by the planer can cause the plastic component to warp or melt, altering the intended shape and decreasing the overall durability of the decking. Furthermore, the wood fibers may splinter or break, resulting in an unsightly and unsafe surface. Planing can also void the warranty on the composite decking, leaving the homeowner responsible for any repair or replacement costs.
Alternatives to Planing
If you wish to improve the appearance or even out the surface of your composite decking, there are alternative methods to consider:
- Sanding: Sanding is a viable option to smoothen the surface of composite decking. Using a fine-grit sandpaper or a handheld orbital sander, you can carefully remove imperfections or rough spots. However, it is essential to note that sanding can also void the warranty on the decking, so be sure to consult the manufacturer’s guidelines beforehand.
- Filling: Another method to address minor imperfections is by filling them with a composite deck repair kit. Follow the instructions provided with the kit to ensure a proper repair. While this may not address larger issues or unevenness, it can significantly improve the appearance of the decking.
- Replace or Cover Affected Boards: If a specific area or board on your composite decking is severely damaged or uneven, you may consider replacing the board entirely or covering it with a new piece of composite decking. This approach allows you to maintain the overall integrity and safety of your deck.
Consult the Manufacturer
Before undertaking any modifications or repairs to your composite decking, it is crucial to consult the manufacturer’s guidelines and warranty information. Manufacturers often provide specific recommendations for maintenance, cleaning, and repair of their composite decking products. Disregarding these guidelines may result in voiding the warranty or causing irreparable damage.
While it is technically possible to plane composite decking, it is generally not recommended due to the composition of the material. The plastic component can melt or warp, and the wood fibers can splinter or break, leading to an uneven and potentially unsafe surface. Instead, consider alternative methods such as sanding, filling, or replacing affected boards, while keeping in mind the manufacturer’s guidelines and warranty. By following these recommendations, you can maintain the longevity and aesthetics of your composite decking.
