Choosing your sanding equipment
You have a small room, and there is only one room you have in the entire house with hardwood that needs immediate refinishing. Our advice is not to make any big investment in the form of a professional drum sanding machine. Go for the random orbital Sander.
The advantages of using orbital sanders over professional drum sanders
- An orbital sander is a way lesser investment than a drum sander;
- It does not require too much expertise to use it;
- For a newbie who has no great experience in the wood grains, it is more forgiving.
The disadvantages of the orbital sander vis a vis the drum sander
- Orbital sanders will take a long time for you to complete finishing even if it is a small room
- It may take a lot of effort for you to remove old finish with it
- An orbital sander can move in all directions with ease, and it may run away from you, causing more scratches that may become difficult to remove.

Prepping the floor
The room will have to be emptied of everything, including the furniture and fixtures. If you have blinds or curtains in the room, consider removing them, if that is not an option, you could use giant plastic bags to cover them and then tightly seal them before you hang them at least 4 feet above the ground where it will not interfere with your sanding and refinishing work.
– Take help for clearing the furniture off the room;
– Make sure someone is assisting you in carrying the orbital Sander to your worksite
– Do not forget to take frequent breaks
– Use goggles, earbuds, face masks and gloves to ensure that the dust and fume do not affect you
Determine the floor thickness
You must have your hardwood flooring to be a minimum of .75-inch-thick to be able to sand as many times. If the floor thickness is less than 75, you may not want to risk because you could potentially do more damage to the floor. It is recommended that a professional be called in if the hardwood floor is thin.
All about sandpaper
You will need a lot of sandpaper in varying grits. Go for the open face sandpaper as they are easy to use as well as economical.
- Coarser grits of the sandpaper are needed for the first round of manual sanding and completely remove the old finish from the wood.
- The finer grits will be used one by one in the process of sanding it to get the smoothest finish that is possible.
- Paint on the floor will require 20-grit sandpaper. Shellac and varnish will require a minimum of 36. You may want to finish the final sanding with a 100-grit paper. Buy extra sandpaper from your home depot, depending on the condition of your floor. Save the extra papers for later, or you could return what you cannot use.
Complete sanding the room
Use the orbital Sander as though you are mowing the lawn. Proceed row by row and, in a way, overlapping space by at least half of what is Sander’s width. Make numerous passes over the same part of the floor to ensure that the sanding is perfect.

Do not forget the corners. Use sandpaper manually to remove the stains from hardwood from near them if the orbital Sander is difficult to go there.
Vacuum and wipe the dust
Once the sanding is done, use a vacuum cleaner to suck up all the dust from the sanding. That once done, pick up a tack cloth and use it to remove any dust or hair that has left on the floor.
What to do if a hair of a screw is trapped inside the polyurethane?
You must remove that strand of hair from them. But you must do it in a bid to not damage the flooring. First of all, sand over the strand of hair; then carefully dig it out with a sharp pin. Now re sand the same area with finer grit sandpaper.
Using the sealer to refinish the floor
A lot of homeowners do not use sealer coats to refinish their floors. However, if your room sees heavy traffic and the wooden floor is very prone to stain easily, kindly consider sealing it with a good quality sealer. If you choose to seal the floor, try to use an oil-based polyurethane sealer instead of a water-based one. Don’t forget to wear gloves as it may irritate some skin types. Make sure that the sealer is spread evenly, and you have a strategy to exit the room to leave it to dry for a minimum of 48 to 72 hours before you move in your furniture.
Once you are through, look at your gleaming hardwood floor and pat your back. And never allow anyone to tell you that you could not do this. You are an epitome of patience, grit, and determination.
