Because your deck is the joy of the family, it is exposed to extreme conditions and intensive uses. When your friends come and join you on the deck, they look at it and say, "Your deck is simply beautiful."
So is Sikkens...
Decks and Handrails
Horizontal surfaces are exposed to the sun's damaging ultraviolet rays. These areas also receive high levels of moisture from the rain and snow and this moisture can sit on the surface for days or even weeks. Decks that are built low to the ground (less than two (2) feet) or are skirted cannot be well ventilated therefore, the moisture cannot escape below the deck. This means the boards are constantly subjected to moisture not only from above but also below.
Decks are subject to physical damage from foot traffic and scraping garden furniture. Physical damage to the coating accelerates the damage caused by the elements.
Due to these factors, we say that a deck is a unique situation. For a coating to properly perform under this variety of harsh conditions, there is little room for haphazard preparation, application or maintenance.
Since the horizontal surfaces of a deck are subjected to ultraviolet rays, standing water and excessive moisture, any film building coating can experience some degree of peeling because these elements can literally push the coating off the wood surface. Therefore, it is essential to properly prepare the surface as described in the exterior wood preparation procedures section before coating.
