What Grit Sandpaper For Wood Floors

When it comes to refinishing wood floors, choosing the right sandpaper grit can make all the difference. Using sandpaper with too coarse a grit can leave scratches in the wood, while using sandpaper with too fine a grit will not remove enough material, resulting in a less-than-perfect finish.

The ideal grit of sandpaper for wood floors will vary depending on the condition of the floor and the desired outcome. For floors that are in good condition and simply need a light sanding to remove dirt and scratches, a fine-grit sandpaper (120- to 150-grit) is usually sufficient.

For floors that are more damaged or have a thick layer of finish, a medium-grit sandpaper (80- to 120-grit) will be necessary to remove the old finish and level the surface. For floors that are in very poor condition or have deep scratches, a coarse-grit sandpaper (60- to 80-grit) may be necessary to remove the damaged wood and create a smooth surface.

Once you have determined the appropriate grit for your floor, it is important to sand in the direction of the wood grain. This will help prevent scratches and ensure an even finish. It is also important to use a sanding block or sander to ensure that the sandpaper is applied evenly and does not damage the wood.

Here is a general guideline for choosing the right sandpaper grit for wood floors:

120- to 150-grit sandpaper: For light sanding to remove dirt and scratches.
80- to 120-grit sandpaper: For medium sanding to remove old finish and level the surface.
60- to 80-grit sandpaper: For heavy sanding to remove damaged wood and create a smooth surface.

Once you have sanded the floor to the desired smoothness, you can apply a new finish. Be sure to follow the manufacturer's instructions for applying the finish, and allow the finish to dry completely before walking on the floor.
