Ultimate Guide to Sanding Floorboards: Revitalize Your Wooden Floors

Posted on July 2, 2023


Comprehensive Guide to the Basics of Sanding Floorboards

The timeless appeal of wooden floors has made them a popular choice among homeowners for centuries. But like all things, wooden floors need proper care to maintain their charm. One of the most effective ways to revitalize old, worn-out wooden floors is by sanding them. This blog post will guide you through the basics of sanding floorboards.

What is Floor Sanding?

Floor sanding is a process that involves removing the top surfaces of a wooden floor by abrasively sanding the boards with a variety of sandpaper grits. The result is a smoother surface, free from old finishes or imperfections, ready for a fresh finish.

Why Sand Your Floors?

Sanding can breathe new life into your wooden floors. It removes old finishes, stains, and minor damages, such as scratches or dents. It also prepares the floor for a new finish, enhancing the wood’s natural beauty and prolonging the floor’s life.

Tools and Materials Needed

Before you start sanding, gather all the necessary tools and materials. These include:
  • Drum or belt floor sander
  • Edger sander
  • Detail or orbital sander
  • Variety of sandpaper grits
  • Safety goggles
  • Dust masks
  • Ear protection
  • Vacuum cleaner
  • Broom and dustpan

Preparing for Sanding

Safety First

Before you begin, ensure you have appropriate safety equipment. Sanding can produce a large amount of dust, so use safety goggles to protect your eyes, a dust mask for your lungs, and ear protection from the noise of the machines.

Prepare the room.

Remove all furniture, rugs, and any other objects from the room. Look for and remove any nails or screws that are protruding from the floorboards. They can damage the sanding machine and create an uneven surface.

The Sanding Process

Choose the Right grit.

Sandpaper comes in different grits, and the choice of grit depends on the condition of your floor. A lower grit number (like 24 or 36) means coarser sandpaper that can remove more wood, which is useful for very old or damaged floors. Higher grit numbers (like 80 or 100) provide a finer sanding, which is used for finishing touches.

Start with the Drum or Belt sander.

The drum or belt sander is for the main areas of the floor. Always sand along the grain of the wood, never across it. Start with coarser-grit sandpaper and work your way up to finer grits. Wood Floor Sanding

Use an Edger sander.

An edger sander is used for areas where the drum or belt sander cannot reach, such as the edges of the room. Be careful to blend the edge-sanding area with the drum-sanding area for a consistent look.

Detail Sanding

Use a detailer or orbital sander for corners and hard-to-reach places where the edger cannot reach.

Cleaning Up After Sanding

Once the sanding is complete, it’s time to clean. Sweep the floor and then vacuum it thoroughly. Make sure you remove all dust, as it can affect the new finish’s application and appearance.

Post-Sanding: Applying the Finish

After sanding, you’re ready to apply the new finish. This could be a stain if you want to change the wood’s color or a clear finish to enhance the natural grain. Follow the manufacturer’s instructions for best results.


Sanding floorboards is a challenging yet rewarding task. It revitalizes your wooden floors, restoring their beauty and prolonging their life. Though it requires effort, understanding the basics and taking it step-by-step can make the task manageable, even for a DIY beginner. So, roll up your sleeves and bring back the charm to your wooden floors.
