What are the steps to using a Floor Sander on a Deck

If your deck is made of pressure-treated lumber, cedar, or redwood, it needs to be sanded before staining or painting. And if you want a smooth surface that’s safe for bare feet, you will need to use a floor sander.

You can do this by following these steps:

  1. Start with the right sander: You will need a heavy-duty floor sander to do the job right. And make sure you get one that’s equipped with a dust bag, so you can collect all the sanding dust.
  2. Prepare your deck: Before you start sanding, sweep and clean your deck to remove any dirt or debris. Then, use a putty knife to fill any cracks or nail holes.
  3. Test the sander: Before you start sanding, test the sander on a small, inconspicuous area of your deck. This will help you get a feel for how the sander works and how much pressure to use.
  4. Start sanding: Begin in one corner of your deck and work your way across, following the grain of the wood. Overlap each pass slightly to ensure you don’t miss any spots. Start with coarse-grit sandpaper, and move to finer grits as you go. It is important to sand in the direction of the grain, and don’t press too hard to avoid damaging the wood.
  5. Change the sandpaper: Sandpaper becomes less effective as it wears down. Replace it frequently with fresh paper.
  6. Finish up: Once you have gone over the entire deck, sweep away any dust or debris. Then, enjoy your newly smooth and safe deck.

Follow these simple steps and you will have a smooth, sanded deck in no time.
