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.

An exterior paint job typically lasts between 5 and 10 years, though this can range from 3 to 17 years depending on several factors. The longevity is influenced by the quality of the paint and primer, the quality of the application, the local climate, and the type of surface being painted. For example, paint on wood siding may need to be redone every 3 to 7 years, while painted brick can last up to 17 years. Aluminum siding often needs repainting every 5 years.

Yes, you can paint galvanized chain link, but the process is a bit more difficult as it requires additional prep work. Before applying the primer and paint, you must remove the original coating from the metal, which can be time-consuming. If the original coating is not removed, the primer and paint will not bond properly and cause peeling over time.

You shouldn't paint a metal fence. Painting doesn't necessarily damage a corrugated metal fence, but these types of fences are meant to flex, and paint can easily chip and break off. Latex paints can address this issue, but those tend not to be very weather-resistant. Certain paints can trap moisture in the corrugation, which can rust the metal and lead to corrosion. And finally, if you paint a copper fence, it won't patina, which is one of the main reasons people buy copper.
