Sanding Stair Treads

Begin by sanding the unfinished treads. Set up the saw horses and place each tread across them one at a time, to be sanded individually. The idea behind sanding is to get the treads as smooth as possible. For initial sanding you will want to use low grit sandpaper such as 80 Y. Sand treads in the direction of the grain, making sure to sand over the entire surface of the tread. I would recommend sanding the tread in horizontal sections that cover the entire length of the tread. You will want to apply some pressure whether you are using a power sander or a hand sander. Once you have gone over the tread several times you will want to see how smooth the tread is by running your hand over the surface of the tread. Ensure that the tread is as smooth as possible, if there are still some remaining rough areas run the sander over the tread once more using a 80 grit or a 120 grit, until the tread is completely smooth. Remember to also sand the nosing of the tread (top and bottom).
