Sanding Hardwood Floors With A Belt Sander 1

How to sand hardwood floors with a belt sander

Be prepared

Before getting started with the sanding process, you need to be well-prepared. You need to take out the mats, curtains and furniture from the room. If there is any item that you cannot take out, you can cover them. Also, make sure that your working area has proper ventilation so that fresh air can enter the room. It is better to seal the area if you find dust can escape through this area.

Without it, you have to take care of your safety. You should use safety goggles, face masks. Wearing earplugs is recommended as your sander will produce noise. 

Inspecting the floor

You need to inspect your floor as well. As a part of this, you have to check the thickness of your hardwood floors first. It will fix how many times you need to sand it down. Then, give the floor a quick check to find if there is any uneven area or not.

If you find so, you have to diagonally sand your floor across its length. If the area is even, then you will need to sand along the wood length only.

The condition of floorboards will determine the abrasive grade you need to start sanding with. You should finish with the 120 grit size. I guess you know that there are three abrasive grades. If you begin with 40 or 60 grit sandpaper, then you should move into 80 or 100 grit sandpaper. You have to finish with 120 grit sandpaper.

Start sanding

Before getting started with sanding, make sure that the sander is tilted before switching it on. It will prevent the abrasive face from coming into contact with your floor. Once you finish sanding the floorboard length, then tilt your sander for lifting the abrasive from the ground.

Depending on the state of your floor, you have to sand either along the length or diagonally. 

  • Sanding diagonally

You will need to sand diagonally if your boards are not level. You should fit an accurate abrasive grade to your belt sander. It should be 40 or 60 grit sandpaper. You can start from the corner. Tilt your sander, switch on it and move the sander across your floor diagonally to another corner.

Before reaching the skirting board in another corner of your room, tilt your machine and lift abrasive from the wood. Then turn around and repeat this process. 

You should do it following a parallel line to the first pass. You have to overlap this first pass slightly. Carry on the process, overlapping every previous pass slightly until you sand the whole room.

For your next phase, repeat this process as mentioned, except you face an adjacent corner so that your sander crosses first right angle sanding.

  • Sanding across the wood length

After sanding diagonally two times, or if you find your floorboards are in good condition to move into the next step, you can use the second abrasion grade either 80 or 100 grit. Start with sanding along the wood length.

You should start from one corner of your room and run across the wood length with your sander. After you reach another site, tilt and lift your sander, turn around and move parallel with the previous pass, overlapping as you have done with the diagonal process.

After completing the two passes, you are supposed to find a smoother finish on one pass that is the grain direction. You should complete the rest passes in the same way.

Once you are done with sanding with the second abrasion grade, move to 120 grit sandpaper and do the above-mentioned process again. For reaching the corner of your room, you can use a handheld sanding block. Thus, you will be able to have a smooth and finishing floor.

To conclude, you now know all you need to know to correctly sand hardwood floors using a belt sander. If you follow this advice and follow the instructions exactly, your floors will look wonderful.
