You can nail or screw composite decking, but 3-inch decking screws are the better fastener choice. Unlike nails, decking screws won’t back out of the composite material over time. There’s also little danger of splitting composite material when driving screws, so you don’t need to pre-drill holes unless otherwise recommended by your decking manufacturer.

The best way to sand a deck is by cleaning it, sanding the boards and stairs with 60- or 80-grit sandpaper, and sanding the railings and posts with 80-grit sandpaper. You should sand in the direction of the wood grain to avoid damaging the timber. When sanding your deck, use medium pressure and aim for an even sand. Pressing too hard with a sander can damage decks, as most are softwoods.

Whether composite decking is better than wood depends on your priorities, especially regarding budget and maintenance. Composite decking offers superior longevity (30 to 50 years) and durability, and it is low-maintenance, requiring no sanding, staining, or sealing. In contrast, wood decks typically last 10 to 30 years and need refinishing every few years. While the upfront cost of composite is higher than wood, the reduced maintenance can lead to long-term savings. If a lower initial cost is the primary factor, wood is the more affordable choice.

When building an outdoor or deck gate, it's crucial to use durable wood that can withstand harsh weather conditions like sunlight, rain, wind, and snow. Redwood and cedar are excellent choices as they naturally resist decay. While redwood is considered more elegant, cedar is a more affordable option. Other suitable woods include oak and pressure-treated pine, which is specifically treated to resist rot. Although some softwoods like pine are popular, untreated softwoods such as pine and spruce should generally be avoided for outdoor projects because they are susceptible to damage from water, rot, and the sun. Ultimately, it's wise to consider your local climate when selecting the right wood for your gate.
