Wood is a very popular building material not only for exterior applications such as window frames and cladding but also for the creation of outdoor living space such as wooden patios, decks, fences and garden furniture.
Without some type of protective surface coating, most wood will deteriorate very rapidly during outdoor exposure. Besides excellent resistance to weathering and UV, other features such as good adhesion, protection against liquid water ingress and a good balance between hardness and flexibility are key requirements for exterior wood coatings.
