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.

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.

You’ll need to wait until the surface is completely dry, which can take anywhere from 24 to 48 hours under optimal conditions. The waiting period depends on several factors, including the type of siding and the weather conditions. Trying to paint before the surface is completely dry can trap moisture under the paint, leading to bubbling, blistering, and mold growth.
