How to Sand a Wooden Floor
If your wooden floor is in poor condition, the thought of sanding it must have crossed your mind. However, hiring a professional can be expensive, and thus you may drop the idea. Why do you need to hire a professional anyway when you can do this simple task on your own?
Sanding is actually pretty simple, and once you complete the task, your wooden floor will look as good as new. But how to sand a wooden floor? This must be a question running through your mind especially if you have never performed this task before. Don’t worry, as we have a laid out step by step procedures on how to sand a wooden floor.
Start Preparing Your Room
• Firstly, you have to empty your room completely. After doing so, get rid of old floor coverings, and anything else that you got attached to your wooden floor. Next, you have to vacuum clean the floor really well and then sweep it clean.
• If you notice any nails and they are peeping above the surface, then you need to hammer them with the help of a nail punch. If you do not do so, then the nails may tear your sandpaper, and may even damage your machine. Basically, the surface that you will begin sanding on must be completely free of protrusions.
• You also need to collect and keep aside the tools that you will require. This includes a belt or edging wood sander and a floor or drum sander. You need not necessarily buy it, instead, hire it, and that will make your wooden floor sanding a lot cheaper. Also, you will require sandpaper, nail punch, vacuum cleaner, and hammer.
• Some protection gear you will need include proper shoes, ear protection, and a dust mask.
Begin Sanding The Room
• If your floorboards are extremely uneven, then you should use a big drum sander to get started. Using this equipment, begin sanding diagonally to your floorboards to even the floor out. Next, start sanding in the direction of your floorboards. For sanding around your room’s edges, you will need to use the edging sander. And, for the rest of the floor, you need to use the big drum sander.
• You will also need sandpaper of different grits – 24, 40, 80, and 100 – to get the ultimate perfect result. If the surface of your wooden floor is extremely uneven, then you need to start by using the roughest grit sandpaper (24). Move the sandpaper at an angle across your wood floor grain. If your wood is in an average state, then the 40 grit sandpaper will be perfect for you to start with.
• After you have successfully removed maximum varnish, grime, and stain, you can begin using the less coarse sandpaper. When you work using the very rough sandpaper, it works in a tough way, and then the surface of your floor also becomes rough. But, when you start using the finer paper, the floor roughness will vanish, and it will become smoother and smoother. You must also use the finest paper (100) as it will make your floor super smooth and give a professional appearance.
• One very important thing to remember is to keep changing your sandpaper frequently. The more often the papers are changed, the quicker you will be able to complete your sanding job. Also, remember it is a good idea to have more sandpaper than you will need. This becomes all the more important if you plan to do the job on a weekend when the stores will be closed. Do not worry if you have some extra left. Most stores will not mind you returning them.
• Approximately, you will need 5 sheets of 120 grit sandpaper, 8 sheets of 80 and 40 grit sandpaper, and 12 sheets of 24 grit sandpaper for both the large drum sander and the edging sander.
Get the Professional Look by Varnishing Your Floor
• After you complete sanding, the next thing you need to do is to get rid of all the dust and dirt. If you have an average-sized room, then a 75mm brush will prove to be perfect for the purpose. Though, you can even opt for a roller brush.
• Applying the varnish is super easy. All you need to do is to remember that the brush strokes are in the direction of your wood grain.
• Ideally, you should first use a stain, and this can be followed by a clear varnish. Many people prefer using a colored varnish, but this can wear over time, and then you will notice scratch and chip here and there. However, if you stain and varnish your wooden flooring, then only the varnish can disappear with time, and the chips will not be as visible.
• After sanding, your floor remains unprotected, so you should varnish it without wasting any time. It will be best to apply three coats on normal traffic places, and four coats on places like hallways. Do not move any of your furniture, not unless the varnish has dried and cured. This can take as long as 14 days to a maximum. Since this is a lot, people mostly wait for around 48 hours, and you can try that as well.
How Much Time Will You Have To Invest?
If you plan to sand the floor on your own, be ready to invest some time. Usually, the professionals may complete the job in nearly 2-3 hours. But, when people try to do it on their own, it takes at least 25 hours for 4 rooms. If you have less number of rooms, then the time needed will also reduce.
Varnishing, however, does not take much time. You can expect to complete this task in about an hour or so.
To Conclude –
Now that you know how to sand a wooden floor, you can complete this job next weekend. It will take a bit of your time and lots of effort, but it is going to be completely worth it. You yourself will be surprised with the result, with the way your wooden flooring looks after sanding and varnishing. It will appear almost completely new, and you are going to love it for sure.
