(horizontals only) This process is done the same way hard wood floors are refinished.  We first clean and prep the deck.  We then set all the nails approx.1/8 inch below the surface.  The entire perimeter of the deck is sanded with a special spinner edge sander.  Then the floor is cut with a large Drum Floor Sander.  Depending what’s on the existing floor, it can be 1to3 cuts and anywhere from a 1/16 to a 1/8-inch layer of wood removed.  This leaves a brand new freshly sanded surface.  Sanded wood literally looks like a brand new deck.  Generally the only time a deck is sanded, is when you have an existing coating that is peeling and flaking.  When this occurs the surface is sanded then sealed with a natural seal giving the deck a combination stain seal two tone looks.  If the verticals need to be re-stained then we re-stain them also.
