How To Use A Random Orbital Floor Sander
If you are looking for a way to refinish your hardwood floors and bring back their natural shine, using a random orbital floor sander can be a great option. Random orbital floor sanders are versatile and efficient machines that can help you achieve professional-looking results. However, using one for the first time can be intimidating. This guide will walk you through the steps of using a random orbital floor sander, so you can confidently tackle your floor refinishing project.
Step 1: Prepare the room
Before you begin sanding, make sure to prepare the room properly. Remove all furniture, curtains, and any other items that may get in the way. Cover any vents or electrical outlets with plastic to protect them from dust. Sweep or vacuum the floor thoroughly to remove any loose debris.
Step 2: Choose the right sandpaper
Choosing the right sandpaper is crucial for achieving the desired results. Different grits of sandpaper will remove different amounts of material from the floor. Start with a coarser grit, such as 36 or 40, to remove the old finish and any deep scratches. Gradually switch to finer grits, such as 80 and 120, to smooth out the floor and prepare it for refinishing.
Step 3: Start sanding
Attach a piece of sandpaper to the bottom of the random orbital floor sander. Start sanding in one corner of the room, moving the sander in a smooth and even motion across the floor.

As you sand, the random orbital floor sander will create a lot of dust. To avoid excessive dust buildup, sand in stages. Start with the coarsest grit and sand the entire floor. Then, vacuum or sweep the floor to remove the dust before switching to a finer grit. Repeat this process until you have achieved the desired smoothness.
Step 5: Clean up and finish
Once you have finished sanding, clean up the dust and debris from the floor using a vacuum or a broom. Wipe the floor with a damp cloth to remove any remaining dust. At this point, you can apply a stain or finish of your choice to enhance the beauty of your newly sanded floor. Follow the instructions on the product label for the best results.
By following these steps and taking the necessary precautions, using a random orbital floor sander can be a rewarding and successful experience. Remember to wear protective gear, such as goggles and a respirator, and always read the manufacturer’s instructions before operating the machine. With a little practice, you’ll be able to achieve professional-quality results and enjoy the beauty of your refinished hardwood floors for years to come.
Preparing Your Floor
Before you begin using a random orbital floor sander, it’s important to properly prepare your floor. This will ensure that you achieve the best results and avoid any damage to the surface. Follow these steps to prepare your floor:
1. Clear the area
Remove all furniture, rugs, and other objects from the room. This will make it easier to maneuver the sander and prevent any accidental damage to your belongings.
2. Inspect and repair any damage
Thoroughly inspect the floor for any cracks, gaps, or loose boards. These should be repaired before sanding to ensure a smooth and even surface. Use wood filler or putty to fill in any cracks or gaps, and secure any loose boards with nails or screws.

Clear the Room
Before you begin using a random orbital floor sander, it’s essential to clear the room of any furniture, decorations, or obstacles that may obstruct your path or make sanding difficult. Removing all items from the space will provide you with a clear and open area to work with.
Start by moving any large furniture pieces, such as tables, chairs, or couches, out of the room entirely. If possible, find another area in your home to temporarily store these items until you’ve finished sanding. For smaller or more lightweight furniture, you can move them to one side of the room, ensuring they’re safely out of your way.
Next, take down any wall art, mirrors, or decorations hanging on the walls. Store these in a safe place to prevent them from getting damaged during the sanding process. Additionally, remove any curtains or window treatments that may get in the way or collect dust during the sanding process.
Don’t forget to clean the floor of any loose dirt, debris, or dust that may have accumulated. You can use a broom or vacuum cleaner to thoroughly sweep the floor, ensuring it’s clean and free from any potential obstructions.
Once you’ve cleared the room and cleaned the floor, you’ll be ready to start using the random orbital floor sander with a clear and open workspace. Taking the time to clear the room will make the sanding process smoother and help you achieve the best possible results.
Remove any Nails or Staples
Before using a random orbital floor sander, it is important to remove any nails or staples that may be protruding from the surface of the floor. These can damage the sandpaper or the machine and cause accidents during the sanding process.
Start by inspecting the floor carefully and identifying any nails or staples that need to be removed. Use a pair of pliers or a nail puller to grasp onto the nail or staple and gently pull it out of the floor. Be careful not to damage the surrounding wood.
If you encounter any nails or staples that are difficult to remove, you may need to use a hammer and a punch to drive them further into the wood and then fill the hole with wood putty or a similar material.
Once all the nails and staples have been removed, sweep or vacuum the floor to remove any debris. This will ensure that the sanding process goes smoothly and that the sander does not get clogged or damaged.
Sweep and Vacuum the Floor
Before using a random orbital floor sander, it is important to sweep and vacuum the floor thoroughly. This will help remove any loose dirt, dust, or debris that may be present on the surface.
Start by sweeping the entire floor with a broom or dust mop to collect larger particles. Be sure to sweep into corners and along baseboards to remove any hidden dirt. Use a dustpan to collect the swept-up debris and dispose of it properly.
Next, use a vacuum cleaner with a brush attachment to remove any remaining dust and smaller particles that may have been missed by sweeping. Move the vacuum cleaner slowly and methodically across the entire floor, making sure to cover every area including edges and corners.
Take your time during this step to ensure that the floor is as clean as possible. Any debris left on the surface can interfere with the sanding process and may cause damage to the sander.
Once you have finished sweeping and vacuuming, visually inspect the floor to make sure it is free of visible dirt or dust. It is also a good idea to run your hand across the surface to feel for any remaining debris. Repeat the sweeping and vacuuming process if necessary.
Note: If there are any sticky or stubborn spots on the floor, try using a mild cleaner or a damp cloth to remove them before proceeding with the sanding process. Avoid using excessive moisture, as it can damage the wood and make it more difficult to sand.
By thoroughly sweeping and vacuuming the floor before using a random orbital floor sander, you will ensure a clean and debris-free surface for optimal sanding results.
Choosing the Right Sanding Disc
When using a random orbital floor sander, it is essential to choose the right sanding disc to ensure optimal results. The type of sanding disc you select will depend on the type of material you are working with and the desired finish. Here are some factors to consider when choosing a sanding disc:
Grit: The grit of the sanding disc determines how coarse or fine the sandpaper is. Coarser grits, such as 40 or 60, are ideal for removing old finishes or deep scratches. Finer grits, like 100 or 120, are suitable for smoothing rough surfaces and preparing for a new finish. Remember to start with a coarse grit and progress to finer grits for the best outcome.
Material: Consider the material you are sanding. For hardwood floors, it is recommended to use sanding discs made from aluminum oxide, as they are durable and long-lasting. For softer woods or delicate surfaces, such as pine or antique furniture, consider using sanding discs made from softer materials like silicon carbide.
Size: Sanding discs come in various sizes, typically ranging from 5 to 8 inches in diameter. The size you choose will depend on the size of the sanding pad on your random orbital floor sander. Ensure that the sanding disc you select matches the size of your sander to achieve consistent results.
Attachment Method: There are different attachment methods for sanding discs, including hook and loop (Velcro) and adhesive-backed discs. Hook and loop discs are easy to attach and remove, allowing for quick disc changes during the sanding process. Adhesive-backed discs offer a strong bond and are usually more durable, but they require more effort to remove and replace.
Specialty Discs: Depending on your needs, you may also consider using specialty sanding discs for specific tasks. For example, there are sanding discs designed for removing paint or varnish, as well as discs for polishing or buffing. These specialty discs can help you achieve specific results and may be worth exploring for your project.
By considering these factors and choosing the appropriate sanding disc for your random orbital floor sander, you can achieve excellent results and efficiently complete your sanding project.
Determine the Grit Level for your Floor
Before you begin sanding your floor with a random orbital floor sander, it’s important to determine the grit level that is suitable for your specific floor type. The grit level refers to the coarseness or fineness of the sandpaper that you will be using.
The ideal grit level for your floor will depend on various factors, such as the condition of the floor, the type of wood or material, and the desired level of smoothness. Generally, the lower the grit number, the coarser the sandpaper and the more material it will remove. Conversely, higher grit numbers indicate a finer sandpaper that will provide a smoother finish.
To determine the right grit level for your floor, consider the following guidelines:
| Floor Condition | Grit Level |
|---|---|
| Old, worn-out finish or deep scratches | 24-40 |
| Surface scratches or light wear | 60-80 |
| Smooth, bare wood | 100-120 |
These guidelines are just a starting point, and you may need to adjust the grit level based on your specific circumstances. It’s always a good idea to start with a coarser grit and progress to finer grits to achieve the desired results.
Remember to always follow the manufacturer’s recommendations for your specific floor sander and sandpaper. Additionally, make sure to wear protective gear, such as a dust mask and safety goggles, when sanding to prevent inhalation of fine dust particles.
By determining the appropriate grit level for your floor, you can ensure that your random orbital floor sanding project is successful and that you achieve the desired smoothness and finish.
Select the Correct Size of Sanding Disc
When using a random orbital floor sander, it is important to choose the correct size of sanding disc for the job. The size of the sanding disc will affect the efficiency and effectiveness of the sanding process. Here are a few tips to help you select the right size of sanding disc for your project:
Consider the Size of the Floor Area
The first thing to consider when selecting the size of the sanding disc is the size of the floor area you plan to sand. Smaller floor areas, such as bathrooms or small bedrooms, may require a smaller sanding disc, while larger floor areas, like living rooms or hallways, may require a larger sanding disc for more efficient sanding.
Avoid Overlapping Sanding Lines
Another thing to keep in mind when choosing the size of the sanding disc is to avoid overlapping sanding lines. Overlapping sanding lines can create uneven results and make the sanding process more time-consuming. By choosing a sanding disc that is slightly smaller than the width of your floor sander, you can minimize the risk of overlapping sanding lines and achieve a more even sanding finish.
Tip: If you are unsure about the size of the sanding disc to use, it is better to start with a slightly smaller size and gradually increase the size if needed. This will allow you to test the sanding results and make adjustments accordingly.
In conclusion, selecting the correct size of sanding disc is crucial for achieving optimal results when using a random orbital floor sander. By considering the size of the floor area and avoiding overlapping sanding lines, you can ensure a more efficient and effective sanding process.
