- exterior primers to major bare wood prior to applying a topcoat. Most exterior oil-based primers contain resins that allow some penetration and breathability. They are more flexible than interior types and could contain stronger mildewcides and fungicides. They are a good choice for blocking out stain such as cedar tannins that may leach through water-based coating.
- topcoat of either a high quality acrylic or oil-based paint. The 100 percent acrylic paints are measured to have more flexibility, are able to breath and have a longer life when exposed to direct sunlight. On the downside, they tend to be less abrasive than oil-based paints and are not recommended for areas where pooling water can accumulate.
- the coating manufacturer's recommendations for normal maintenance.
