If your wood floor has lost its shine and looks dull and worn out, it might be time to consider refinishing it. Refinishing a hardwood floor is a daunting task, but with the right tools and techniques, you can transform your old, worn-out floor into a beautiful, polished surface that looks as good as new. One of the essential tools you’ll need for this task is a square floor sander.
A square floor sander is a powerful machine that uses abrasive sandpaper sheets or discs to sand the surface of a wooden floor. In this blog post, we’ll provide you with a step-by-step guide on how to use a square floor sander effectively. We’ll cover the necessary tools and materials, safety procedures, and provide detailed instructions on how to sand and refinish a wooden floor using a square floor sander.
Definition Of Square Floor Sander
A square floor sander is a power tool used for sanding and refinishing wooden floors. It features a large square sanding pad that rotates at high speed, removing old finish and surface imperfections from the wood. The machine is designed to sand large areas quickly and efficiently, making it an essential tool for anyone looking to refinish or restore a wooden floor. Square floor sanders can be rented from hardware stores or home improvement centers and come with a range of grit sandpaper sheets or discs that can be used to achieve different levels of smoothness on the wood.
The tool is often used in combination with other sanding tools such as edgers and hand sanders to achieve a smooth, even surface. Square floor sanders can be challenging to operate and require careful attention to safety procedures to prevent injury or damage to the wood surface.
Drum Sander vs. Square Buffer: Which is Best
When it comes to floor sanding, two of the most popular options are the drum sander and the square buffer (or square floor sander). While both tools are effective at sanding wooden floors, there are some key differences to consider when deciding which is best for your project.
The drum sander is a heavy-duty machine that uses a large, rotating drum to sand the floor. It is best suited for large, flat areas and can quickly remove a lot of material. The drum sander is ideal for removing old finish or leveling out a floor with deep grooves or uneven spots. However, it can be difficult to control and may leave marks on the floor if not used properly.
The square buffer, on the other hand, is a lighter machine that uses a large, square sanding pad to sand the floor. It is best suited for smaller, more confined spaces and can easily maneuver around corners and edges. The square buffer is ideal for maintaining a floor’s finish or smoothing out minor imperfections. However, it may not be as effective at removing deep scratches or dents in the floor.

Ultimately, the choice between a drum sander and a square buffer depends on the size and condition of your floor, as well as your level of experience and comfort with the tool. For large, heavily damaged floors, a drum sander may be the best option. For smaller or less damaged floors, a square buffer may be more efficient and easier to control.
How To Use A Square Floor Sander: Step By Step Guide
Using a square floor sander can transform an old, worn-out wooden floor into a beautiful and polished surface. In here, we’ll provide you with a step-by-step guide on how to use a square floor sander effectively, ensuring a smooth and professional finish.
Things You Will Need
Before starting to use a square floor sander, it’s important to gather all the necessary equipment and materials. Here list of everything you’ll need to ensure a successful floor sanding and refinishing project.
- A square floor sander
- Sandpaper sheets or discs of various grits
- A vacuum cleaner or broom
- Safety glasses
- Ear protection
- Dust mask or respirator
- Work gloves
- Painter’s tape
- A plastic sheet or drop cloth
- Floor finish or sealer
Step 1. Preparing The Area
The first step in using a square floor sander is to prepare the area you will be working on. This means removing all furniture from the room, and thoroughly cleaning the floor to remove any dirt, debris, or dust. If there are any nails or staples in the floor, remove them with pliers or a pry bar. You want the surface to be as clean and smooth as possible before you begin sanding.
Step 2. Choose The Right Sandpaper
Selecting the right sandpaper is crucial to achieving a good result. The grit of the sandpaper you choose will depend on the condition of the floor. If the floor is in relatively good condition, you may only need to use a fine grit sandpaper to achieve the desired result. However, if the floor is badly scratched or has a lot of old finish on it, you may need to start with a coarse grit sandpaper and work your way up to a finer grit.

As a general rule of thumb, you should start with 36-40 grit sandpaper for heavy sanding, then move to 60-80 grit for medium sanding, and finally 100-120 grit for fine sanding. Be sure to follow the manufacturer’s recommendations for the specific type of sandpaper you are using.
Step 3. Put On Safety Gear
Sanding a floor can be a messy and noisy process, so it’s important to wear appropriate safety gear. Before operating the square floor sander, put on safety glasses, ear protection, a dust mask or respirator, and work gloves. The sander can create a lot of dust and debris, and the noise level can be harmful to your hearing, so it’s important to protect yourself.
Step 4. Secure The Sandpaper
Once you have chosen the right sandpaper, it’s time to attach it to the square floor sander. Follow the manufacturer’s instructions for attaching the sandpaper to the sanding pad. Ensure that the sandpaper is securely attached to the sanding pad and that it is facing the correct direction.
Step 5. Test The Sander
Before starting to sand the entire floor, test the sander in a small, inconspicuous area to get a feel for how it works. Move the sander back and forth in the direction of the grain, applying light pressure. Check the sandpaper frequently to ensure it’s not clogging or wearing down too quickly.
Step 6. Sanding The Floor
Once you are comfortable with the sander, it’s time to start sanding the floor. Begin in a corner or along the edge of the room, working in small sections. Keep the sander moving at a consistent pace and in the direction of the grain. Avoid pressing down too hard on the sander, as this can create uneven spots on the floor. As you move across the floor, overlap each pass slightly to ensure a consistent finish.
Step 7. Change Sandpaper
As the sandpaper becomes worn or clogged, replace it with a fresh sheet or disc. Be sure to follow the manufacturer’s instructions for changing the sandpaper. This will help you achieve a consistent and smooth finish.
Step 8. Sand the Edges
After you have sanded the entire floor, it’s time to move onto the edges. For this step, you will need to use a handheld orbital sander. Begin by attaching a fine-grit sandpaper to the sander and starting in the corner of the room. Work your way around the edges of the room, sanding any areas that the square floor sander couldn’t reach.
Step 9. Finishing the Floor
Once you have sanded the floor and the edges, it’s time to finish the job. Start by vacuuming the floor to remove any dust or debris that may have accumulated during the sanding process. Next, apply a wood stain if desired, following the manufacturer’s instructions carefully. Finally, apply a clear coat of polyurethane to protect the wood and give it a glossy finish. Be sure to follow the manufacturer’s instructions for drying times and application techniques.

Step 10. Vacuum And Clean The Floor
After you have finished sanding and staining the floor, it’s time to clean up the area. Start by removing all of the sanding equipment and putting it away. Use a broom and dustpan to sweep up any sawdust or debris that may have accumulated during the sanding process. Finish by vacuuming the entire room to ensure that all dust and debris are removed.
FAQ About How To Use A Square Floor Sander
How long does it take to sand a floor with a floor sander?
The length of time it takes to sand a floor with a floor sander varies depending on the condition of the floor and the type of sander being used. For a square buffer sander, which is ideal for floors in good condition with very little finish, it may be a relatively quick process. However, if the floor is in poor condition, it may take several hours or even a full day to complete the sanding process.
Does sanding the floor remove scratches?
Yes, a complete sanding of a real wood floor will remove scratches. However, it’s important to note that this will not work on engineered wood floors with a real wood surface, as they can only be sanded once or twice before all of the real wood is sanded off.
Do you push or pull a floor sander?
When using a floor sander, it’s important to push it forward, rather than pulling it towards you. Turning the sander on and off can be done by pressing the buttons on the front of the handle, with the left button turning it on and the right button turning it off. It’s important to maintain a good grip on the sander before turning it on, as it may try to pull away from you.
Using a square floor sander can be an efficient way to sand your hardwood floors, provided you follow the proper steps and safety precautions. Before using a floor sander, it’s important to prepare the area properly and have the necessary safety gear on hand. Take care to sand in a consistent pattern and always keep the sander moving to avoid creating dips in the floor. With a little patience and effort, you can transform your old, scratched-up hardwood floors into beautiful, smooth surfaces that will last for years to come.
