Unlock Superior Results with Our Wood Floor Sanding Tips | Floor Restoration Guide

Wood floor sanding is a crucial process for revitalising hardwood floors. A well-executed sanding process forms the perfect foundation for an excellent finish, transforming worn-out floors into stunning surfaces. This comprehensive guide shares some fantastic tips to ensure you achieve a great finish through effective wood floor sanding.

The purpose of sanding

Sanding serves several key purposes:
  • It removes old, worn-out finishes.
  • It smooths out scratches, dents, and other surface-level imperfections.
  • It flattens the floor, ensuring it’s even across the room.
  • It prepares the wood to accept a new finish uniformly.

Tools You’ll Need

The right tools will make the sanding process easier and more efficient. Here’s what you’ll need:
  • Drum Sander: This heavy-duty tool is used for the main floor area.
  • Edger: This tool is used for getting to the areas close to the walls that the drum sander can’t reach.
  • Hand sander or sanding block: for corners and very tight spaces
  • Sandpaper: You’ll need different grits, from coarse (36 or 40 grit) to medium (60 grit) to fine (80 or 100 grit).
  • Safety Gear: including safety goggles, a dust mask, and ear protection

Wood Floor Sanding Tips for a Great Finish

Tip 1: Preparing the Area

Ensure that the room is fully cleared out. Remove all furniture, rugs, and decorative elements. Cover vents, doors, and windows with plastic sheeting to contain dust.

Tip 2: Inspect the floor

Look for protruding nails, staples, or any other material that could damage your sanding equipment or cause an uneven finish. Hammer them down or remove them entirely.

Tip 3: Start with the drum sander.

The drum sander will do the heavy lifting. Starting with coarse-grit sandpaper, move the sander steadily and slowly, going with the wood grain. Remember, it’s better to make multiple light passes than one too-deep pass. Wood Floor Sanding Basics

Tip 4: Don’t Forget the Edges

Use the edger, fitted with the same grit sandpaper as the drum sander, to reach the perimeter of the room. Move in a sweeping motion to ensure an even finish.

Tip 5: Switch to Finer Grits

Start with a coarse grit to remove the old finish and scratches. Then, switch to medium and finally fine-grit sandpaper to smooth the floor. Remember to use the same grit sequence with the edger.

Tip 6: Clean Between Grits

Use a vacuum or microfiber mop to clean up the dust before switching to a finer grit. This prevents coarse particles from scratching the floor during the next sanding pass.

Tip 7: Hand Sand for Perfection

After using the mechanical sanders, some spots will still need attention. Use a hand sander or sanding block to reach these areas.

After Sanding: Choosing and Applying a Finish

After sanding, the next step is choosing and applying a finish. Your choice of finish will depend on your desired look and the type of wood. Always test a small area before applying the finish to the entire floor.


Sanding is a demanding but rewarding process. By following these tips, you can confidently approach your wood floor sanding project, knowing you have the knowledge to achieve an excellent result. With some patience and elbow grease, your floors can be returned to their original glory, creating a beautiful base for any room.
