No, it is not okay to paint over rotted wood. Painting over rotted wood will not address the underlying issue and can trap moisture, leading to further decay. Properly addressing the rotted wood by removing and replacing or repairing the damaged areas is necessary before you can even consider painting.

If you have a smooth, already bonded concrete surface, painting a concrete pool deck can be a great way to brighten up the area and add longevity. If the surface has another covering or a different type of paint has been used previously, you won’t be able to paint it without removing the existing coating. Wooden decks benefit from painting as it helps to keep them watertight. Quality pool deck paints also help make the surface less slippery and less likely to gather mold and mildew or prematurely crack.

Yes, pressure-treated wood can occasionally turn green due to certain preservatives, such as copper-based chemicals, used during the treatment process. These chemicals react with the wood, creating a greenish tint. The good news? It's temporary, and the color will fade over time. Staining or painting can also help hide any unwanted hues.

Painting a damaged pool deck is not recommended if the substrate is crumbling, cracking, spalling, or otherwise actively deteriorating. Continuing deterioration will result in the paint also delaminating or flaking off the damaged surface. Minor damage such as chips or hairline cracks that are not actively deteriorating can often be repaired enough to paint over. A damaged pool deck with a lot of cracking and deterioration should be replaced for best results.
