What Grit Sandpaper for Wood Floors : Expert Tips for Perfect Finishing

Refinishing wood floors is a great way to give new life to a worn-out, old floor. One of the essential steps in this process is sanding the wood to remove the old finish and create a smooth surface for the new finish to adhere to. Choosing the right grit sandpaper is crucial in achieving the desired result. In this comprehensive guide, we will discuss the various grits of sandpaper and how to choose the right grit for sanding wood floors.

Understanding Grit Sizes

Grit size refers to the number of abrasive particles per square inch on the sandpaper. The lower the grit number, the coarser the sandpaper, and the higher the grit number, the finer the sandpaper. Different grit sizes are used for different stages of the sanding process.

Initial Sanding

When starting the refinishing process, the first step is to remove the old finish and level any uneven areas on the wood floor. For this initial sanding, it is recommended to use coarse grit sandpaper in the range of 24 to 36 grit. Coarse grit sandpaper is effective in rapidly removing the old finish and leveling the surface. It is essential to keep the sander moving to avoid creating any uneven spots in the wood.

Intermediate Sanding

After the initial sanding with the coarse grit, the next step is to use medium grit sandpaper to further smooth out the wood surface. Medium grit sandpaper typically falls in the range of 60 to 100 grit. This grit effectively removes any remaining old finish, scratches, and imperfections left by the coarse grit sandpaper. It prepares the wood for the final sanding stage.

Final Sanding

The final sanding stage involves using fine grit sandpaper to achieve a smooth and uniform surface. Fine grit sandpaper usually ranges from 120 to 220 grit. It removes any remaining imperfections, smoothens out the wood, and prepares it for the application of the new finish. This stage is crucial in achieving a professional-looking result.

Choosing the Right Grit

When choosing the right grit sandpaper for wood floors, it is important to consider the condition of the floor, the type of wood, and the desired finish. If the wood floor has a heavy build-up of old finish or is deeply scratched, starting with a lower grit sandpaper is necessary to effectively remove the imperfections. For finer woods or floors in better condition, starting with a higher grit may be appropriate to avoid over-sanding.

Tips for Sanding Wood Floors

Here are some additional tips to keep in mind when sanding wood floors:

  • Always sand in the direction of the wood grain to avoid creating visible scratches.
  • Use a floor sander with the appropriate grit sandpaper for the best results.
  • Change the sandpaper regularly to maintain effectiveness.
  • Take the time to sand each area thoroughly and evenly for a uniform finish.
  • Wear protective gear, including a dust mask and goggles, when sanding to protect yourself from wood dust.
