Dictionary Definition:
Heavy paper coated on one side with sand or other abrasive material and used for smoothing surfaces.
Choosing Sandpaper
- Start with a low-number grit and step up to higher numbers for the best finish.
- Choose between aluminum oxide and garnet types of paper. Garnet is more expensive, but it lasts longer. Aluminum oxide is good for general use; garnet is best for finishing and sanding between layers of varnish.
- Go with 80 to 100 grit papers to remove existing finishes.
- Try 110 to 150 grits for preparatory finishing and follow with 180 grit for the final sanding of softwoods.
- Use 300 to 400 grit papers between layers of varnish and final sanding of hardwoods.
- Consider 800 grit wet/dry for finishing extremely hard woods.
Warning:
Wear a dust mask and safety goggles when sanding.
