The longevity of paint on wood depends on factors like the quality of the paint, surface preparation, exposure to elements, and maintenance. Exterior paint on wood surfaces can last 5 to 15 years or more with proper care and maintenance. Interior paint tends to have a longer life span, often 10 years or more. Regular cleaning, touch-ups, and addressing any issues like peeling or cracking can extend the life of the paint. 

The best paint for an older deck depends on the material and whether or not your deck already has a coat of paint. Generally, if your deck already has paint on it, you should choose the same type of paint when repainting the deck. For example, if an old deck has oil-based paint on it, stick with oil; if your deck has water-based paint, choose water-based paint. 

Yes, you can and should paint or stain pressure-treated wood, as this helps prevent the surface from cracking. However, it is crucial to wait for the wood to dry out completely from the chemical treatment process before applying a finish. If the wood is still wet, the paint will not adhere properly. The drying time can range from weeks to six months. To test if the wood is ready, drip some water onto a board. If the water is absorbed, the wood is dry enough for painting or staining. If the water beads up on the surface, it needs more time to dry. You can build with the wood while it's still wet, but you must wait for it to dry before painting.

The need for a topcoat on a painted deck depends on various factors, primarily the type of paint used and your desired level of protection. Many premium deck paint formulations are self-sealing, eliminating the necessity for an additional topcoat. These paints often have built-in additives that substantially protect against moisture, UV rays, and everyday wear and tear.
