Although composite decking is extremely durable, it’s also susceptible to extreme heat. Prolonged exposure to sunlight can cause fading, warping, and cracking. Composite also retains heat more than wood, which makes it dangerous to walk on in the summer. You can help prevent heat damage by only building with composite in shaded areas or using rugs to cover the hottest spots.

Start with a 60- or 80-grit sandpaper when sanding a deck, though this could change depending on the type of wood that comprises the deck and how smooth you want the overall finish. If you prioritize a smooth final finish, progress to a finer grit like 120 or 150. Avoid ultra-fine grits for traditional sanding, as it could close up the wood pores and make it harder to apply a finish down the line.

Before installing a new railing, check the condition of the deck frame and joists, especially around the perimeter where posts attach. If boards are loose, soft, or show signs of rot, the structure may need repair. A deck pro can inspect your framing to confirm it meets load-bearing requirements.

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.
