How to prevent your sandpaper from sliding

Just by folding your sandpaper into thirds, it will hold together much better than folding it in half. The paper will be steady in your hands, which helps make the job much quicker. Plus, you get more use out of the whole surface of the paper.

Step by Step Instructions

1 Choosing the correct sandpaper
2 Hand sanding and electrical sanders
3 Attaching sandpaper to an electrical sander
4 Sanding blocks
5 Sand in a circular motion
6 Change paper often
  • Step 1. Choosing the correct sandpaper

    When choosing sandpaper, remember to lower the number the more coarse the sandpaper. It’s a good idea to start with a 60 or 80 grade and then a 120 to finish it off. If your paper is too coarse, you can end up making deep gouges and scratches, which may need filling and sanding again.
  • Step 2. Hand sanding and electrical sanders

    You can use a plain board with paper attached and sand by hand. Or you can use electric sanders, which reduce the work.  Round orbital sanders are very good on plaster walls, but on woodwork you have to be careful because they can leave marks on your wood.
  • Step 3. Attaching sandpaper to an electrical sander

    Sandpaper for electrical sanders comes with Velcro backing so you can easily stick it to the sander.
  • Step 4. Sanding blocks

    Sanding blocks are handy for corners and around cornices. Wrap a piece of sandpaper around the block and sand in a circular motion.
  • Step 5. Sand in a circular motion

    The best motion for sanding is in a small circular motion. If you’re sanding bare wood, run with the grain so you don’t get scratches on the timber. Never use force or pressure on the instrument. Let the weight of the machine carry it.
  • Step 6. Change paper often

    Always check your sandpaper for signs of wear. As the grit becomes clogged with dust and paint, it becomes less effective.  Change your paper as necessary.

Health & Safety

Please make sure you use all equipment appropriately and safely when following the advice in these D.I.Y. videos. You need to be familiar with how to use equipment safely and follow the instructions that came with the equipment. If you are unsure, you may feel it is safest to consult an expert, such as the manufacturer or an expert Bunnings Team Member.

Grave health hazards are linked to asbestos, which may be in homes built up to 1990. Health hazards may result from exposure to lead-based paints in older materials and copper chromium arsenic (CCA) treated timber. For information on the dangers of asbestos, lead-based paint and CCA treated timber and tips for dealing with these materials contact your local council's Environmental Health Officer or visit our Health & Safety page. You can also use a simple test kit from Bunnings to indicate the presence of lead-based paint.
