How to sand a deck
SANDING back your deck before you give it a stain is a great way to improve the smoothness of the finish. As long as you get your preparation right and use the right tools, this simple job will help make your deck look and
feel good for years to come.

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: Sand 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 such as 40-grit, then go over the surface again with a finer grade such as 120-grit to create a smoother finish.
Step 3: 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.
Get your deck ready for summer.
