In most cases, sanding an old deck before staining it is necessary to achieve a decent finish. If your old deck has a relatively new stain finish on it and you're only doing touch-ups, you can generally skip the sanding part. However, if your goal is to make the deck look and function better, sanding first is a must. 

The best and fastest way to remove paint from a deck often involves combining a chemical stripper with a pressure washer. Gel-based paint strippers are highly recommended because their thick consistency makes them less messy and easier to apply than liquid strippers. After applying the stripper to loosen the paint, you can use a pressure washer to efficiently wash away the residue. When using a pressure washer for this task, it's important to use a low pressure (under 1000 PSI) to avoid forcing too much moisture into the wood, which could lead to mildew or rot.

Deck skirting shouldn’t touch the ground, especially if you have a wood deck, which is vulnerable to moisture. Ideally, you should leave at least 3/4 of an inch of space between the deck skirting and the ground for more ventilation. Pros also recommend that you incorporate about 1 square foot of space for ventilation for the underside of the deck to every 150 square feet of decking. Proper ventilation prevents mold growth and rot that can damage your deck.

You typically don’t need a railing and handrails on a deck that’s less than 30 inches from the ground. However, consider adding them regardless. Railings provide additional safety for you and your guests who use your deck—plus, railings give the deck a more finished look than it would have without them.
