1. BLACK+DECKER BDERO100 – Best Overall

BLACK+DECKER is one of the leading manufacturers of high-quality and innovative power tools. And the BDERO100 from the brand is no different. Featuring an extremely lightweight and compact design, it is one of the most versatile sander options you need to check out on this list.

2. WEN 6301 – Best Budget-Friendly

WEN has been manufacturing some of the top-rated and highly efficient power tools since 1951. When it comes to sanders, WEN is often the number one choice for many users. For this reason, we have included the 6301 electric detailing palm sander from the brand on this list.

As a palm sander from a brand that has been active for over 70 years, the WEN 6301 exceeds our expectations. For starters, the powerful 1 amp motor can produce 13,500 orbits per minute of sanding power, making it highly productive and super fast.

Furthermore, it sports a lightweight design and weighs just a little over 2 pounds, thereby fitting right under your palm to help you deliver accurate sanding results without getting tired. Also, the angled tip enables you to reach tight spaces for further precision.

Apart from this, you can change the sandpaper grits as per your requirements, thanks to the hook-loop base pad. It features dust slots that collect the sawdust, maintaining a cleaner work environment. And finally, it is backed by a year of warranty from the manufacturer.

The WEN 6301 has all the features that you would expect from a powerful sander. That being said, people may face a hard time finding the papers for this sander as it is not easily available. Apart from this minor issue, it does an excellent job in all aspects.

3. Makita 9403 – Best Low Noise

Next up, we have a highly efficient sander by Matika, a Japanese brand producing power equipment since 1915. That said, the 9403 belt sander from this brand is one of the quietest options out there and it is backed by a year of warranty from the manufacturer.

To be honest, we were thoroughly impressed by the features that Makita 9403 had to bring to the table. Firstly, it produces only 84 decibels, making it one of the quietest sander options available on the market. Plus, it is extremely efficient and fast, all thanks to the 1,640 feet per minute speed of its 4-inch belt.

Apart from this, it features labyrinth construction that protects the bearings and the motor from contamination, hence making it a lot more durable. It comes with a sizable front grip, allowing you to use it for a long time without pain or discomfort. Impressive right? Well, there’s more.

The dust bag turns 360 degrees, ensuring it collects dust from all around the sander. And, finally, we were really happy to see that the manufacturer backed the product with a 1-year warranty.

The Makita 9403 is undoubtedly one of the best belt sanders out there, given its features and durability. That being said while testing it, we noticed that the front roller tends to get hot and also, it is not totally round. We really wish that Mitika had been a little more careful while designing the front roller. But apart from this, it is one of the top-grade belt sanders on this list.

Grit Type: Medium | Grit Number: 80 | Voltage: 0 | Power Source: Corded Electric | Max Speed: 1,640 ft./min


Founded in 1924 in America, Dewalt is one of the best sellers of power tools all over the world. That being said, allow us to introduce you to the DCW200B palm sander from the brand that is popular for its fine grit type and innovative design. Keep reading to learn more about this spectacular sander.

For us, the Dewalt DCW200B palm sander is not just any random sander. This is mainly because of its brushless motor that does an exceptional job in sanding all wooden surfaces. Its low height of 1/4 inch will allow you to get close to the material for accurate sanding.

Apart from this, the variable speed dial allows you to adjust the speed between 8,000 and 14,000 orbits per minute to suit your sanding requirement. The clamps provided at the bottom will help you to hold the paper tightly, enabling easy installation. Furthermore, it comes with a dust-sealed switch that protects the product from dust, ensuring a long life.

What’s more? Well, it features a rubber over mold grip that allows you to sand for hours without pain. This makes the product super comfortable to use.

Despite having so many handy features, the Dewalt DCW200B does not come with a battery and a charger; in fact, you will have to purchase them separately. This was slightly disappointing, given its brand value and price. Having said that, it is still a top-notch option if you consider all the other exceptional features.

5. SKIL SR250801

We are halfway through with this list, and it’s time to talk about a sander from SKIL, a famous brand for delivering all types of technologically advanced sanders. Featuring a powerful motor and a compact design, the SKIL SR250801 is not an option you would want to miss out on.

The main highlight of this product is its micro-filtration technology; it picks up dust particles and helps keep the work environment clean. Also, we were quite happy to find out that the sanding sheets can easily be changed, thanks to its hook and loop system.

Apart from this, the SKIL SR250801 features a powerful motor, producing 12,000 orbits per minute that comes in handy in a wide range of sanding applications. The soft grip design allows it to be held quite comfortably, while the counterweight balance reduces vibration, enabling you to work for longer hours at a go.

Overall, it is one of the most affordable options available on the market, and also, we were mighty pleased to see that the manufacturer has not skimped on the warranty.

SKIL SR250801 is an exceptional choice when it comes to sanders. That being said, it may not be the right choice for those looking to use sanders for heavy-duty professional projects. Also, it is not compatible with mouse sandpaper.

Grit Type: Medium | Grit Number: 120 | Voltage: 120 | Power Source: Corded Electric | Max Speed: 12000 RPM

6. Bosch ROS20VSC

Now that we are nearing the end of our list, it’s time to talk about a product from Bosch. It is a brand that has been dedicated to producing the highest-quality power equipment since 1886. The ROS20VSC orbital sander from the brand is tough competition to all the other options on this list.

We liked pretty much all the features that come with this product. However, for us, the main USP of this unit is its pad-dampening design that assists in getting rid of swirl marks on surfaces. So, you can expect a smoother finish on your deck.

Furthermore, the sanding pads hold onto the sander quite firmly, all thanks to the easy disc attachment system. Plus, it comes with a dust filter system that traps the smallest of dust particles, ensuring a cleaner and safer work environment. Also, you can adjust the speed of this sander according to your requirements between 7,000 and 12,000 OPM.

We couldn’t ignore its soft grip, which makes it very comfortable to hold, allowing you to have different grip positions and reducing fatigue while sanding. Plus, it is backed by a year of warranty.

Without a doubt, the Bosch ROS20VSC orbital sander is an excellent option. However, it comes with a couple of issues. While testing this product, we noticed that the dust filter is not that efficient, and we also found out that it is on the noisier side.

Grit Type: Fine | Grit Number: 80 | Voltage: 120 | Power Source: Corded Electric | Max Speed: 12000 RPM

7. Ryobi P411

To be fair, this list would have remained incomplete without the addition of this top-notch, versatile sander by Ryobi. Even though the P411 sander from Ryobi is our last entry, its features are as good as all the other options. Keep reading to find out more about this product.

There are quite a good number of things that we really liked about this product. To begin with, we were very impressed with its cordless technology. Not only does it save you from the hassle of managing the long wire, but also it makes the sander very portable.

The motor is capable of producing 10,000 orbits per minute, allowing you to perform any polishing or sanding job with ease. Furthermore, it features a rubber overgrip, making it very comfortable to hold despite the severe vibrations that the motor generates. Magnificent, isn’t it? Well, it doesn’t just stop there.

The built-in dust bag collects all the dust particles from the workspace, limiting the post-cleaning job to a bare minimum. And also, it comes at a very reasonable price.

Even though Ryobi P411 does a decent job in most departments, it is not the right choice for those who are seeking a heavy-duty professional sander. It has a fairly weak motor and is only meant for light-duty sanding jobs. Also, the speed cannot be adjusted, which is another disappointment.

Buying Guide For The Best Deck Refinishing Sanders

We hope by now you have gone through the top 7 recommendations. So, were you able to make a decision?

We bet you are still confused. Well, to be honest, the brand name and the price are not the only things you need to consider before making a decision.

There are other factors that you need to keep in mind while buying a top-quality sander for deck refinishing. In this section, we will discuss and take a close look at those factors; we strongly advise you to read through this buyer’s guide very carefully to know more.

  1. Speed

The speed of the sander is one of the most important factors that one should keep in mind before making a purchase. If you are new to sanding, it is natural to like fast-paced sanders.

However, it is not a good choice when it comes to deck refinishing. Different parts of the deck require different sanding speeds. For instance, you will need a slower speed while sanding the railing. So, we strongly recommend going with a sander that comes with adjustable speeds so that you can set it as per your requirements.

  1. Noise Level

Noise level may not be your number one priority while choosing a sander, but it’s important nonetheless. If you have a big project, you might have to sand throughout the day. So, in that case, you will not want to disturb the neighbors or destroy your hearing ability.

So, always go with a lower-decibel sander that produces less noise or at least gets ear protection.

  1. Dust Collection

The sanding process creates a lot of dust; this makes a dust collection feature an important factor to consider while buying a sander.

That being said, in this day and age, most sanders come with attached dust collectors to prevent the dust from flying all over the deck. This helps in minimizing the post-cleanup job to a bare minimum.

What is the best way to maintain my deck after refinishing?

To maintain your deck after refinishing, be sure to clean it regularly, inspect it for mold or mildew, and apply a sealer or stain as needed.

How often should I refinish my deck?

The frequency of refinishing your deck depends on the type of wood and the amount of exposure to the elements. Generally, wood decks need to be refinished every 1-3 years.

What should I do to prepare my deck for refinishing?

Before beginning the refinishing process, it is important to clean the surface of the deck and inspect for any damage. We recommend removing any old sealant or paint, as well as clearing away any debris.

How long does the refinishing process take?

The length of time required for the refinishing process varies depending on the size of the deck, the type of finish, and any additional services that may be required. On average, the process takes 2-3 days.

What are the steps involved in the deck refinishing process?

The deck refinishing process typically includes cleaning and sanding the surface, applying a wood or composite deck stain or sealer, and applying a top coat for protection.


Sanding the deck is very important to eliminate all the stain marks and splinters that accumulate over time. Also, if you are planning on painting it, sanding is the first step. So, if you wish to experience an effortless sanding experience, a top-notch sander is a must-have!

With this, we have reached the end of our informative guide; we hope it has helped you gain some important details about choosing the best sander as per your requirements.

Before signing off, we would like to mention our top picks, so let’s go for a quick recap. BLACK+DECKER BDERO100 is the best overall. WEN 6301 is an affordable option, while Makita 9403 is known for being the quietest belt sander.
