It’s best to prime composite decking before painting. This promotes better paint adhesion, helps create a smooth finish, and can mean the paint job will last longer. Always follow the manufacturer’s instructions for application, allow ample primer drying time before painting (typically 24 to 48 hours), and thoroughly clean the deck boards to promote the best adhesion.

In most cases, sanding an old deck before staining it is necessary to achieve a decent finish. If your old deck has a relatively new stain finish on it and you're only doing touch-ups, you can generally skip the sanding part. However, if your goal is to make the deck look and function better, sanding first is a must. 

Applying a sealer after staining is often recommended, especially for outdoor wood surfaces like decks or fences. It helps protect the wood from moisture, UV rays, and other elements, extending the life of the stain and preserving the wood's appearance. It also enhances the stain's durability and resistance to wear and tear. 

However, in some indoor applications, a sealer may not be necessary, depending on the type of stain used and the level of protection required. Always check the specific product recommendations and consider the wood's exposure and usage when deciding whether to apply a sealer after staining.

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.
