The worn-out look of my old hardwood floors had been bothering me for years. I tried cleaning them with every product under the sun, but nothing seemed to bring back their original luster. I knew that refinishing would be the best solution, but I didn’t want to hire a professional. My friends had recommended using an orbital sander, so I went searching for a way to make it work. Was it truly possible to refinish hardwood floors with just an orbital sander, or was I setting myself up for disaster?

Refinishing hardwood floors is a daunting task for even the most experienced DIYers, but for beginners, it’s easy to feel overwhelmed by the whole process. An orbital sander is a versatile tool, known for its ability to smooth surfaces without creating deep grooves. While it can tackle smaller projects like removing paint, sanding wood furniture, and preparing surfaces for varnish, it presents unique challenges when it comes to refinishing entire floors.
How Does an Orbital Sander Work?
Orbital sanders are essential tools for woodworkers and DIY enthusiasts, but their functionality is often misunderstood. They employ a rotating sanding pad that oscillates or orbits in a circular motion, creating a more uniform and controlled sanding action. The orbiting motion helps evenly distribute pressure on the wood, minimizing the risk of creating deep scratches or grooves that could mar the surface.
The key advantage of using an orbital sander lies in its ability to smooth out imperfections and remove layers of old finish while leaving a consistent surface. This is achieved through the sanding pad’s circular movement, which prevents the tool from digging into the wood as a drum sander might. The sanding pad’s size and the grit of the sandpaper are crucial factors in determining the sanding process’s effectiveness.
Refinishing Hardwood Floors with an Orbital Sander: The Challenges
While an orbital sander can be a valuable tool for smaller sanding projects, it’s generally not recommended for refinishing entire hardwood floors on your own. Several factors contribute to this limitation.

Inconsistency in Sanding
Depending on the size and weight of the machine, an orbital sander can cause inconsistencies in the sanding process, leaving behind uneven areas and swirls on the floor. This is due to the sander’s smaller surface area and the potential for uneven pressure distribution.
Dust Control
Orbital sanders can generate a significant amount of dust, which can cause respiratory problems and create a mess in your home, particularly when sanding large areas like a hardwood floor. While dust collection systems can be attached to some models, achieving complete dust control with an orbital sander can be challenging, especially in confined spaces.
Choosing the Right Tools For Refinishing
Professional floor refinishers rely on specialized equipment that is more suited for the task. Drum sanders are the most commonly used tools for refinishing hardwood floors because they have a larger sanding drum that can cover a wider area efficiently. They are designed to quickly and evenly remove layers of old finish and level the floor surface. Another key tool is an edge sander, which is used to smooth those hard-to-reach areas around the edges of the floor. Edge sanders are typically smaller, handheld units that are easy to maneuver.
Tips for Success with Smaller Projects
While orbital sanders might not be the go-to tool for refinishing entire floors, they can be handy for smaller projects around your home. If you’re using an orbital sander for a smaller project, such as refinishing a table or smoothing a cabinet door, follow these tips to maximize the results:
Use the Right Grit Sandpaper
Start with a coarse grit sandpaper (around 40 grit) to remove paint, varnish, or other coatings quickly and then proceed to a finer grit (around 120 grit) for a smoother finish. Multiple sanding passes with progressively finer grits will help achieve an even surface.
Overlap Your Strokes
Overlapping each sanding pass by 50% will help ensure a uniform finish. Avoid sanding in one direction for too long, as this can lead to scratches and grooves.
Use Moderate Pressure
Applying too much pressure when using an orbital sander can damage the wood or create uneven sanding marks. Let the sander’s weight do the work. Use only light pressure to achieve the desired result.
Clean the Sander Regularly
Keep your sander clean and dust-free. Remove any accumulated dust or debris from the sanding pad and the dust collection bag regularly to prevent clogging and inefficient sanding.
FAQ
- Q: What is the best grit sandpaper for hardwood floors?
A: The final sanding grit is typically 120-150 for a satin finish. A finer grit (around 220-320) produces a smoother, silkier finish, but it’s more prone to visible scratches.
- Q: Can I use an orbital sander to strip a hardwood floor?
A: You may use an orbital sander if you’re tackling a smaller project, but it’s not recommended for stripping entire floors. Drum sanders are better equipped to handle the heavy stripping process.
- Q: Is it better to use a drum sander or an orbital sander?
A: For refinishing large floors, a drum sander is your best bet because it’s faster and provides a more consistent finish. An orbital sander is better for smaller projects and for spot sanding around the edges of a floor where a drum sander can’t reach.

Concluding Thoughts
Refinishing hardwood floors with an orbital sander can be a challenging, time-consuming task, particularly for large areas. While orbital sanders are great for smaller sanding projects, they aren’t ideal for a complete floor-refinishing job. For optimal results, consider investing in professional equipment such as a drum sander and an edge sander.
