Why wood greys and goes rough
Wooden surfaces are vulnerable to weathering. Sun and rain pull the colour out of deck boards and fence pickets, and what's left turns grey, then rough underfoot. Left alone, that discoloration becomes long-term damage.
The usual shortcut makes it worse. A hard blast of high pressure can tear up the soft fibres of the grain and leave splintered boards that catch bare feet and snag clothes. The deck looks cleaner for a week and is weaker for good.
