Step by Step Instructions

1 Prepare the deck surface
2 Use a belt sander to sand large surfaces
3 Use a finishing sander to touch up the edges
  • Step 1. Prepare the deck surface

    Prepare the deck surface for sanding by checking every nail and screw. Make sure they are all countersunk at least a couple of millimetres below the level of the deck. That way they won’t rip your sandpaper when you’re sanding. Use your nail punch to countersink any nails that are sticking up and screw down any screws.
  • Step 2. Use a belt sander to sand large surfaces

    The belt sander is an efficient tool to do a large area of deck quickly. Work the sander backwards and forwards along the grain of the boards. If you’re removing existing stain or paint, start with a coarse grade of sandpaper like 40-grit, then go over the surface again with a finer grade like 120-grit to create a smoother finish.
  • Step 3. Use a finishing sander to touch up the edges

    Work your finishing sander into the edges and corners where the belt sander can’t reach. Remember not to push down too hard – let the sander do the work for you. Once again, if you’re removing existing stain or paint, start with a coarse grade of sandpaper and then smooth the surface over with a finer grade. Once the sanding’s finished, simply sweep down with a broom and you’re ready to stain.
