If you are inexperienced with sanders then you need a sander that is easy to control. As you may know, sanders tend to vibrate a lot,  the sander can easily slip from your hand from the vibration. If you are inexperienced or just want a sander that vibrates less then you should check the Bosch OS50VC.

This sander comes with a vibration control that will minimize the vibration and make the tool super comfortable and easy to handle.  To make the handling process easier, this product also has ergonomic handles that will prevent fatigue.  To make things better, it also has an accurate paper clamping system, this system helps the paper to fit perfectly, it also accepts sticks on paper.

The Bosch OS50VC is also powerful, it comes with a 3.4 amp motor and it’s fast. The speed is from 8,000 to 11,000 OPM’s.  The dust collection is also good. It features a micro-filter canister and screw-off caps to help getting rid of the dust faster.

Overall a great sander, I use it a lot and always does its job.  I mostly use 120-grid paper sanders but you can use different ones. It accepts 60,80,120,180 grits.

If you are looking for a lightweight sander that will give you a smooth performance then make sure to check Makita BO4556.  This sander is a combination of speed, power, and smooth performance.  It only weighs 2.6 pounds. 

This product is made for woodworking and finishing, so it’s a very good choice when it comes to sanding your stairs.  As we mentioned earlier, this sander is powerful and fast. It features a 2.0 amp motor and delivered up to 14,000 OPM’s, making this faster than our first pick.

I use this sander because it is comfortable, it comes with ergonomically rubberizes palm grips that will fit you like a glove and they also help me a lot to control the sander easier. It also has a ball-bearing construction which reduces noise and makes the tool to vibrate less, which makes the control part even easier.

Like most of the sanders, this one too has a dust-collection system which is pretty effective, except for the system, the dust bag has an extra mouth to help you get rid of the dust faster.

Pros:

  • Fast – Super fast, up to 14,000 OPM’s

3. DEWALT DWE6421K

Best Features  DEWALT Random...

  • Powerful
  • Good Dust Collector
  • Fast

My Overall Rating

More detailed review ↴

If you are looking for a sander that has a powerful motor then the DEWALT DWE6421 might be your perfect choice. This sander comes with a very powerful 3.0 amp motor.  Except for power, it also has speed. The speed is 12,000 OPM which is enough for sanding stairs & more.

A thing that I like about this sander is its height. The height of this sander is shorter and allows me to control the tool easier and get closer to the workpiece.  To prevent vibrations this tool has a separate counterweight design plus it has rubber all over areas that usually vibrate more.  You can still feel the vibrations but at a very minimum level.

It has a very good dust collector system. Not only the tool itself gets the dust, but you can also connect a vacuum to the tool that will get the dust. I find this extremely helpful and effective. Speaking of dust, this tool has a dust-sealed switch that protects itself from dust ingestion, this helps a lot to give the switch a longer life.

Pros:

  • Fast – Offers up to 12,000 OPM’s
  • Powerful Motor – Features a very powerful motor, 3.0 amp.
  • Easy Control – The height of the sander is shorter to help you control the tool better.
  • Fewer Vibrations – It has rubber all over areas that usually vibrate.
  • Good Dust Collection System – Except for the tool system you can also connect a hose.
Cons:

  • I don’t like the pad.

4. PORTER-CABLE Belt Sander

Best Features  PORTER-CABLE...

  • Quiet
  • Powerful
  • Good Dust Collection System

My Overall Rating

5 out of 5 stars (5 / 5)

More detailed review ↴

First of all, this is a belt sander. These types of sanders are usually used for sand larger areas because they do it good and fast. They usually are not used for stairs. But this sander will do a great job when it comes to stairs. And sometimes, it is better to have a sander that can be used for different tasks rather than buying one for a specific project.

The PORTER-CABLE 352VS comes with variable speed settings, meaning that you can change the speed. This is helpful, especially if you work with different materials. The speed goes from 850 to 1,300 SFPM.  It has a quick-release belt change that makes the speed changes easier and faster.

It comes with a very unique dust collector. It has a 360-degree dust nozzle that it’s adjustable — haven’t seen this anywhere else, this feature lets you pivot the dust bag, I find this helpful when I have to sand corners or tight spaces.  The dust collector system also allows you to connect a dust vacuum (make sure to check the dust port sizes, a regular vacuum doesn’t fit the port).

To make it better, it also has a powerful motor. The motor is 8.0 amp.

Pros:

  • Speed Variable Settings – Allows you to change the speed from 850 to 1.300 SFPM.
  • Powerful Motor – Features a motor that is made to last, 8.0 amp.
  • Quiet – This tool keeps the volume low thanks to the gear system. It meshes more accurately, which means less noise
  • Unique Dust Collection System – 360-degree dust nozzle that can be adjusted.
Cons:

  • A regular vacuum doesn’t fit the dust port.

5. BLACK+DECKER

Best Features  BLACK+DECKER...

  • 3-Position Grip
  • Cheaper
  • Lightweight

My Overall Rating

5 out of 5 stars (5 / 5)

More detailed review ↴

And the last tool in our best hand sander for stairs is the BLACK+DECKER. This is more a budget sander that won’t do as good as the other 4 I listed. But still, this will do a great job if you are careful enough and only use it for small tasks, such as sanding your stairs. 

This tool features a 3-position grip. The first grip is the palm grip. I mostly use this grip for sanding large surfaces. The second grip is the precision grip, which by the name you can guess what it does. And the last one is the handle grip. I use this mostly when I’m sanding tight surfaces. You can use this grip to sand stair corners.

It comes with a good motor, 1.5 AMP of power, it operates at 1400 orbits/minute. It comes with an effective dust collector system, it also has a see-through dust-canister that helps you know when the dust is full.

Pros:

  • Budget-Friendly – It doesn’t cost as much as the other products listed here.
  • Good Motor – 1.5 AMP of power that runs at 1400 OPM.
  • 3 Position Grip –  Palm Grip, Precision Grip, Handle Grip
  • Dust Collector – Effective, plus it has a see-through canister that helps you see when the dust is full.
Cons:

  • It isn’t as high-quality as the others here, but it still does the job!

How to refinish your staircase?

Before sanding my stairs, they used to look like the typical 90s’ stairs. A wood color that gets boring after a while. Once you get inside my house, the first thing you see is the staircase. I have seen these old stairs a lot of times every time I came back from work. They looked old and I didn’t like them. That’s why I decided to refinish and repaint them.

The sanding process can be done in two ways. With your hands or with a sander. I highly recommend you to use a sander, it’s faster and they do a better job. Plus we have listed the top 5 best sanders for stairs on top of this page (Check them out if you haven’t already). I recommend you to buy one of them and start with the sanding process.

How to?

1. Remove the existing carpet

Some people don’t use carpets, but I do. If you use them too, then make sure to remove them before starting with the sanding process. Depending on your carpets this can be an easy or hard task.  I have used a lot of staples on my carpet so they don’t move. I had to remove all of them one by one, it took me a lot of time to do this. But it has to be done.

If you are lucky and didn’t use anything to hold the carpets then you can just remove the carpets and store them somewhere else ( you can re-use them ).

2.  Patch Holes With Wood Filler

You can skip this step if you don’t have any hole in your stairs. I had a lot of holes to fill because of staples. But I had to fill them all so I can get an even sanding.

3. Sand ’em!

Once you fill all the holes and remove everything (carpets or anything else above the stairs) then it’s time to sand. As I said earlier you can do this in two ways, with your hands using sandpaper or with a sander.  I used a sander and I recommend you do too!

Make sure to use a sander that gives you a smooth finish (Check our recommended list at top of the page). Don’t move your hand too quickly while sanding and try to sand the entire staircase. Learn here How to Sand Wood?

After you are done with the sanding now you will have to get rid of the dust. Sanders for stairs usually come with a good dust collection system, but in the off chance, you still have to use a vacuum to make sure there isn’t dust. You can also use water to wash the stairs before the next step.

4. Re-Paint the Stairs.

The spraying part isn’t that easy, but you can learn everything about this in our paint sprayer section. We have also made a list of recommendations for the best HVLP paint sprayers for wood. Make sure to check it if you need one!

And this is it! This is how you refinish your stairs. If you don’t have a sander, then you should definitely buy it. You can use it for a lot of stuff. Check the best sanders for stairs list to find one.

If you don’t like the color, then you can use a sander for paint removal.

Final Words

We made sure to include everything you need to know to make your stairs look new again. We made a list of the recommended sanders that you can use for your project, plus we made a mini-guide to let you know the steps you need to take in order to refinish your stairs.

A good sander will make the refinishing process a lot of times easier and it will give you better results.
