Wood Siding: The preparation begins with a thorough cleaning to remove any dirt and mildew. Following this, any peeling paint is scraped off, and the wood surfaces are sanded down to smooth out imperfections. A suitable primer for wood is then applied, which is crucial for ensuring both paint adhesion and the durability of the finish.

Vinyl Siding: This type of siding is washed meticulously to get rid of grime and algae. Given vinyl's unique properties, primer application is generally not needed unless the siding is severely faded or specifically recommended by the manufacturer. The focus is on ensuring the surface is impeccably clean for the paint.

Metal Siding: The process includes removing rust and any loose paint, followed by cleaning and sanding the metal to create a smooth base. A rust-inhibiting primer is essential for metal surfaces to prevent future corrosion and to provide a solid foundation for the paint to adhere properly.
