Key Techniques

Use this tool only on rough surfaces and only if you are sure of yourself; it is easy to make gouges if you tip the tool or if you rest it in one spot too long. Always run the sander with the grain, never against it. Don't apply pressure as you work; just let the weight of the sander do the work.

detail sander

For awkward areas, a detail sander can spare you hours of finger-throbbing work. Sanding pads are self-adhesive; just lift one off and put the next one on. Proceed carefully. A detail sander works with an oscillating action. Because it concentrates on such a small area, it takes off material quickly.

hand-sand

Except in hard-to-reach areas, never use abrasive sheets alone--always use some sort of sanding block, either store-bought or improvised. Sanding with a block is less tiring and produces more uniform results.

Tear abrasive sheets to size, rather than cutting them, or you will dull your knife blade quickly. Check that the bottom of your block is clean and smooth. Any debris can tear the paper and mar your work.

Sand only in the direction of the wood grain. Sanding across the grain or in a circular motion can leave hard-to-remove lines. Don't exert a lot of pressure. If you're using the right grade of paper, light strokes are all you'll need.
