How To Sand Floorboards With A Belt Sander
If your hardwood floorboards are looking worn, scratched, or dull, sanding them can bring them back to their original beauty. One of the most efficient and effective tools for sanding floorboards is a belt sander. With its powerful motor and abrasive belt, a belt sander can quickly and easily remove layers of old finish, stains, or imperfections, leaving you with smooth and evenly sanded floorboards. However, using a belt sander requires some skill and caution to avoid damaging the floor or creating uneven surfaces. In this guide, we will walk you through the steps of sanding floorboards with a belt sander.
Step 1: Prepare the Area
Before you begin sanding, it’s important to prepare the area properly. Remove all furniture, rugs, and other objects from the room. Cover any vents, electrical outlets, or light fixtures with plastic sheeting to protect them from dust. If possible, seal off the room with plastic sheeting to prevent dust from spreading to other parts of your home. Ventilate the room by opening windows or using fans to help dissipate the dust.
Step 2: Select the Right Grit
The grit of the sandpaper belt determines how aggressive or fine the sanding will be. Start with a coarse grit, such as 40 or 60, to remove the old finish or imperfections. As you progress, switch to finer grits, such as 80 or 120, for smoothing out the surface. Remember to always sand with the grain of the wood to avoid damaging the floorboards.
Step 3: Sand in Sections
Divide the floor into manageable sections and sand one section at a time. Start at one end of the section and slowly move the belt sander in the direction of the grain. Avoid applying too much pressure, as this can create uneven surfaces or gouge the wood. Continue sanding until the old finish or imperfections are removed and the surface feels smooth to the touch.
Step 4: Finishing Touches
After sanding the entire floor, use a hand sanding block or a smaller sander to reach the corners and edges that the belt sander couldn’t reach. This will ensure that the entire floor is evenly sanded. Vacuum the floor thoroughly to remove all dust and debris. Finally, you can apply a new finish, stain, or varnish to protect and enhance the beauty of your newly sanded floorboards.
Sanding floorboards with a belt sander can be a rewarding DIY project that can transform the look of your hardwood floors. By following these steps and taking the necessary precautions, you can achieve professional-looking results and enjoy a beautifully sanded floor for years to come.
Why Sanding Floorboards is Important
Sanding floorboards is an essential step in the process of refinishing or restoring wood floors. Whether you are working on an old floor that needs a fresh look or a new floor that requires finishing touches, sanding is the key to achieving a smooth and polished surface.
1. Removal of Imperfections
Over time, floorboards can develop scratches, dents, and other imperfections due to everyday wear and tear. Sanding helps to eliminate these flaws, creating a uniform and flawless surface that enhances the overall appearance of the floor. By sanding the floorboards, you can restore their original beauty and remove any signs of damage.
2. Leveling the Surface
Another important reason to sand floorboards is to level the surface. Unevenness and height variations in the floor can make it difficult to walk on and may cause tripping hazards. Sanding helps to smooth out these inconsistencies, ensuring a level and even surface. This not only improves the functionality of the floor but also creates a professional and finished look.
Sanding floorboards is particularly crucial when you plan to apply a new finish. The old finish may have worn off unevenly or have stains and discoloration. Sanding the floorboards ensures that the new finish adheres properly and results in a uniform appearance.
Moreover, sanding also prepares the surface for the application of other products such as stains, sealants, or varnishes. Sanding opens up the pores of the wood, allowing these products to penetrate deeply and provide long-lasting protection. It helps the finish to bond securely with the surface, creating a strong and durable coating that can withstand foot traffic and daily use.
In conclusion, sanding floorboards is an important step in the process of refinishing or restoring wood floors. It removes imperfections, levels the surface, and prepares it for the application of new finishes. By sanding, you can create a smooth, polished, and visually appealing floor that adds value to your space.

Setting Up for Sanding
Before you begin sanding your floorboards with a belt sander, it’s important to properly set up your work area to ensure the best results. Follow these steps to prepare for sanding:
Gather Your Tools and Materials
Make sure you have all the necessary tools and materials at hand. These may include:
- Belt sander
- Safety goggles
- Ear protection
- Protective dust mask
- Nail punch or hammer
- Vacuum cleaner
- Broom or dustpan
- Painter’s tape or plastic sheeting (if needed)
Prepare the Room
Prior to sanding, it’s important to clear the room of any furniture, rugs, and other objects that may obstruct your work. Sweep or vacuum the floor to remove loose debris and dirt.
If you’re concerned about dust getting into other areas of your home, consider taping plastic sheeting or painter’s tape around doorways to seal off the room. This will help contain the dust and make cleanup easier.

- Inspect the sander: Take a quick look at the sander to ensure that all moving parts are in good working condition. Check for any loose screws or parts, and tighten or replace them as necessary.
By following these steps to prepare your belt sander, you will be ready to tackle your floorboard sanding project with confidence and achieve professional-quality results.
Sanding Techniques
When sanding floorboards with a belt sander, it is important to use proper sanding techniques to achieve the best results. Here are some important tips to keep in mind:
1. Safety First: Before starting the sanding process, make sure to wear protective gear such as goggles, a dust mask, and earplugs. This will help to protect yourself from dust and loud noise.
2. Start with Coarse Grit Sandpaper: Begin sanding with a coarse grit sandpaper (around 40-60 grit) to remove any existing finish, paint, or imperfections on the floorboards. Use long, even strokes and move in the direction of the wood grain.
3. Manage Grain Direction: Pay attention to the direction of the wood grain as you sand. Sanding against the grain can cause scratches and uneven results. Always go with the grain for a smooth finish.
4. Keep Sander Moving: Avoid leaving the belt sander in one spot for too long, as it can create dips or gouges in the floorboards. Keep the sander moving at a steady pace to maintain an even result.
5. Gradually Switch to Finer Grit: Once you have sanded the floorboards with the coarse grit sandpaper, gradually switch to finer grit sandpaper (around 80-120 grit) for a smoother finish. This will help to remove any remaining marks left by the coarser grit sandpaper.
6. Use Edge Sander for Corners: For hard-to-reach areas or corners, use an edge sander or hand sanding techniques to ensure thorough sanding and a consistent finish.
7. Mind the Edges: Be careful not to round the edges of the floorboards while sanding. Keep the sander slightly tilted to avoid this and maintain a sharp edge.
8. Final Hand Sanding: After using the belt sander, consider doing a final hand sanding with a fine grit sandpaper to ensure a smooth and even surface. This will provide a perfect base for refinishing or applying a new finish.
9. Clean Up Thoroughly: Once you have finished sanding, take the time to thoroughly clean up the dust and debris left behind. Use a vacuum cleaner or a broom to remove any particles from the floor surface.
10. Protect Yourself and the Floor: After sanding, remember to seal the floorboards with an appropriate finish to protect them from wear and tear. Follow the manufacturer’s instructions for the best results.
By following these sanding techniques, you can achieve professional-looking results when sanding floorboards with a belt sander. Remember to work slowly and carefully, and always prioritize safety throughout the process.
Choosing the Right Sandpaper Grit
When sanding floorboards with a belt sander, choosing the right sandpaper grit is crucial to achieving the desired results. The grit of the sandpaper refers to the number of abrasive particles per square inch of the paper. Each grit has its own specific purpose, and using the right grit for each step of the sanding process can make a significant difference in the final outcome. Here are the main grits to consider:
- Coarse Grits (24-40): These grits are used for initial sanding or to remove old finish, paint, or heavy imperfections from the floorboards. They are highly abrasive and should be used with caution to avoid damaging the wood.
- Medium Grits (60-80): Medium grits are ideal for general sanding and leveling uneven surfaces. They can effectively remove scratches left by the coarse grits and prepare the floorboards for the final sanding.
- Fine Grits (100-120): Fine grits are used for the final sanding process to achieve a smooth and polished surface. They can remove the scratches left by the medium grits and create a perfect base for staining or finishing.
It is important to note that the type and condition of the floorboards will also influence the choice of sandpaper grit. If the floorboards are already in good condition, starting with a medium grit may be sufficient. However, if the floorboards are in poor condition or have a thick layer of paint or varnish, starting with a coarse grit may be necessary.
Additionally, it is advisable to use progressively finer grits for each sanding step to ensure a smooth finish. Starting with a coarse grit and moving to medium and then fine grits will help achieve a more refined result. Remember to always follow the manufacturer’s guidelines for sandpaper grit selection and change the sandpaper regularly to maintain its effectiveness.
In conclusion, choosing the right sandpaper grit is essential for sanding floorboards with a belt sander. The grit selected should match the specific sanding needs and condition of the floorboards. Understanding the purpose of each grit and using them in the correct order will help achieve a smooth, polished, and professional-looking finish.
