Pool decks should be both cleaned and disinfected regularly to
prevent the spread of disease as well as the slipperiness that results from the
growth of bacteria. Depending on the type of deck surface material -- brushed
concrete, textured modified cement or other cement coatings, ceramic tile,
rubber granules, stone, brick, or epoxy aggregate, cleaning procedures may vary
slightly. When pool decks are large enough, the purchase of
a pressure washer is recommended because cleaning and disinfecting decks by
hand would just be too time consuming.
