The Sun has a big part to play when it comes to the deterioration of your exterior Paintwork. The heat from the sun expands the paint, then as it cools it can split and moisture gets in behind the paint causing the wood to rot. Keeping the paintwork well prepared and painted often prevents this deterioration to occur especially on South facing sides of the property.
Woodstain on the other hand has slightly different properties. Unlike paint that sits on top in the wood, woodstain is medium build which means it both soaks into the wood and remains on top too. Woodstain is damaged by the uv in the sunlight which fades, drys and cracks the surface of the stain. Many Woodstains have a uv filter to prevent the sun damage.
