This what makes the difference between quality deck restoration and just deck refinishing, Most of the time you don’t need to bring heavy-duty equipment, like floor drum sander, on the deck during deck refinishing, but light sanding will do the trick. You’ll need to get rid of dead fiber attached the the deck surface, some kind of wood hair, sticking from the wood, as a result of stripping-brightening procedure. There are few different ways to do it, and if you choose hand-held random rotation sanders, be easier on the sandpapers grid. Remember, pressure washing opens wood pores, sanding – closes. If you choose fine sandpaper, it’ll create problems with sealant penetration.
