Yes, you can and should paint or stain pressure-treated wood to help prevent the boards from cracking. However, you must wait for the wood to dry out completely before applying any finish. Freshly treated wood can take weeks or even months to dry; a common recommendation is to wait three to six months. To check if the wood is ready, perform a simple water test: drip some water onto the surface. If the water beads up, the wood is still too wet and needs more time to dry. If the wood absorbs the water, it is dry enough to be painted or stained. You can proceed with building your deck or fence while the wood is still wet, but you will need to wait to apply the paint or stain.

You’ll need to restrain your deck when you notice fading, cracking, peeling, or mold and mildew over a moderate to large area, or when it’s become especially difficult to clean. As for how often to stain a deck, plan to do it every two to three years or whenever you start to notice extended damage.

Many decking oils can help slow down algae growth, but they don't completely stop it. These oils work by sealing the wood, which reduces moisture and, therefore, algae growth. Some decking oils also help protect against UV damage, but they need to be reapplied according to the manufacturer’s instructions to ensure the decking stays protected.

Whether you can paint over your existing paint depends on what’s on there. Most of the time, you’ll want to sand down or scrape off the paint that’s currently coating your surface. Epoxy paint, for example, won’t let new paint stick to the surface. Latex paint is more forgiving and will accept a new coat, but a primer is recommended if you’re switching colors.
