Best Belt Sander for Deck

Deck refinishing is an easy DIY project that you can undertake if you are handy in the slighted manner. Unlike in furniture refinishing, deck sanding involves working over flat and extensive surfaces with some or no edges. So, a typical detail or finishing sander is typically not the best type of sander to use. What you need is a suitable belt sander that can cover more area and run for longer periods. However, the market is full of competitive belt sander options, and it can be quite difficult to make the right selection. If you don't care much for the technical details of belt sanders, we have selected and reviewed some of the best belt sander for deck on the market and broken down their respective features.

Top 5 Best Belt Sander for Deck

1. Makita 9403 4" X 24" Belt Sander

Key Features

  • 1640 FPM
  • 11-Amp Motor
  • 360 degrees swiveling dust bag

The Makita 9403 is one of the most durable and quietest belt sanders you can get on the market today. It comes with a 4-inch and a fixed speed of 1640 FPM. We don't like the non-adjustable speed feature, but it is still suitable for deck sanding. With a powerful 11-Amp motor, it is powerful enough for a variety of woodwork applications. One of the impressive features is the low noise level of the machine. For a belt sander of its caliber, 84dB is really impressive.

Also, the grip design is quite interesting, as large and rightly positioned for comfortable handling. We would have loved to see some cushioning on the grip, but it is not so uncomfortable to hold as it is. For dust collection, it comes with a dust bag that is designed to rotate 360 degrees for more convenient operation. The sander also has a labyrinth construction that seals and protects the motor and bearings from contamination. To assure you of the durability, the manufacturers included a 1 year warranty.

WEN has a lot of belt sanders on the market, but the HB3216 offers one of the best performances for deck sanding. The 7-Amp motor is not the most powerful on the market, but it should perform well enough when it comes to deck refinishing. Interestingly, it comes with an adjustable speed feature that allows you to choose any speed between 787 - 1312 FPM. Also, the lock-on power switch feature makes continuous sanding possible, without gripping the trigger continuously.

Like any other typical belt sander, it comes with a dust collection feature that includes a dust collection chamber, a dust port adapter, and a dust port reducer. The package also comes with two bench-top clamps, in case you would like to mount the sander on your bench-top. The 3 x 21 inch dimension, in addition to the various other options, make the WEN HB3216 one of the best belt sanders for deck sanding.

3. TACKLIFE Belt Sander

Key Features

  • 6 adjustable speed settings
  • Rubber-coated handles

The Tacklife PSFS1A belt sander comes with a 5-Amp motor that is perfect for deck re-sanding. Admittedly, the power is not the best you can get, but the other features of the sander will make it worthwhile. The sander comes with two metal screw clamps that make it possible for the sander to be turned over and fixed to a table for table sanding. Furthermore, the sander comes with a lock-on button that makes it more convenient to operate.

It features a dust collecting box that detaches easily for disposal. You can also connect the sander to external vacuum machines through the 32mm or the 35mm vacuum dust adapter. The speed of the sander can also be adjusted between 360 - 560RPM. The grip is also a comfortable one, as it comes with a soft rubber covering that reduces hand fatigue and makes for a strong grip. It would interest you to know that the package comes with 13 sanding belts.

  • Variable Speed Dial

If what you need is a sander that has an adjustable speed setting, this is one of the products you should consider. It has a variable speed setting between 850 - 1300 FPM that can easily be controlled with the variable speed dial; this makes it versatile and suitable for different woodworking projects. The sander is also designed for flush sanding. The 8-Amp motor is perfect for deck sanding projects and other heavy stock removals.

The heavy-duty steel construction makes it sturdy and durable. It also accounts for effective heat dissipation. It does come with an effective dust collection system that includes a handy 360-degree adjustable top dust nozzle that lets you pivot the bag. If you would like to connect your vacuum cleaner, it comes with an external port for that. The unique gear system and the serpentine drive belt are responsible for the quiet operation of the machine.

5. SKIL 7510-01 Sandcat Belt Sander

Key Features

  • 6-Amp Motor
  • Auto-track belt alignment
  • Pressure control technology

The highlight of the Skil 7510-01 Belt Sander is the pressure control technology that alerts the user when excessive pressure is applied. If you are a beginner or an inexperienced woodworker, we recommend this sander for you. With a 6-Amp motor, it is just powerful enough for deck sanding. However, we do believe that the motor could be more powerful. With an approximate weight of 7.5lb, it falls under the lightweight category, and it is very easy to handle and move around.

The dust collection system is also better than most, as it includes a completely enclosed plastic dust container and a micro-filtration system. You can even connect an external vacuum if you like. Interestingly, it also comes with an auto-track system that keeps the belt centered on track at all times. You can sand right up to the edge of your deck, as it is also designed for flush sanding. It is also one of the most affordable options you can get on the market.
  • Pressure control technology
  • Flush edge sanding
  • Lightweight machine
  • Auto track system
  • Grip is quite small

Overall Best - Makita 9403 4" X 24" Belt Sander

The Makita 9403 Belt Sander is our overall best pick. Of all the sanders we reviewed, it has the most powerful motor, rated at 11 Amps. This makes it a versatile sander that can be used for a variety of other tasks apart from deck sanding. It is also one of the most durable options, with its labyrinth construction that protects the motor and bearings from contamination. The only downside to this sander is that non-adjustable speed. Furthermore, it is one of the quietest belt sanders you can get, making a mere 84dB of sound, with a powerful motor notwithstanding.

Features and Factors to Consider When Buying a Belt Sander

Indeed, you can't just purchase any belt sander model without stopping for a second to consider some important factors. Some of the critical features and factors to consider when buying a belt sander for deck refinishing are discussed below.

Engine Power

Engine power will determine how efficient a sander will be over different types of surfaces. On harder surfaces, engines with more powers are needed. The engine power is rated in amps, like in most other power tools. The higher the amp the more powerful a sander is. However, you should select engine power relative to the projects for which they will be used.


Size does not really affect how belt sanders function, but it certainly influences mobility and ease of use. The common sizes are 3" x 21", 3" x 21" and 4" x 24". When it comes to deck refinishing, any of these sizes are suitable, but for very large decks, you should go for the largest belt size. On the other hand, the smaller sizes are better for delicate sanding work.


In belt sanders, speed is rated in feet per minute (FPM). The number of passes a machine can do within a fixed amount of time determines the speed rating. High-speed machines are not always the best, especially if you are not experienced in woodworking. What you should look for is a belt sander with an adjustable speed selection. This way, you get to select the speed at which you best operate the machine.

Surface Size

This is the size of a sander's contact surface with the work area. A large area like a deck surface requires a reasonably large contact surface in a sander for fast operation. However, if you require precision in your sanding, a sander with a small contact surface area is best.

Dust Collection

Any type of mechanical sander should come with a reliable dust collection system, as a lot of sawdust is produced during the sanding process. Most belt sanders come with dust bags that take care of the collection, while some are designed to be connected to external vacuum cleaners.

Grip Design

Belt sanders are always held during the sanding operation, so they should come with ergonomically designed handles for comfortable handling. Check the grip design carefully before you make a final selection. Adjustable handles make it easier to sand comfortably at different angles.

Type of Sanding Belts Used in Different Operation

There are four common types of sanding belts, and they come with different characteristics that influence their suitability for different sanding purposes.

Zirconia Alumina Sanding Belt

This is one of the toughest sanding belts you can get, and it has a recognizable blue color. One of the most interesting things about zirconia alumina belts is that they are self-sharpening. Nonetheless, they require high force to sand effectively. They are perfect for sanding hardwood surfaces, metals, and other surfaces that require heavy grinding. You can get them in grit sizes ranging from 24 - 120. They are not the best option for polishing projects, but they are perfect for preparing surfaces for refinishing.

Aluminum Oxide Sanding Belt

This is easily the most common sanding belt. It is the best for general purpose sanding, as one of the most durable and affordable sanding belts. It typically comes in a reddish-brown color and is available in 24 - 400 grit sizes. The versatility of aluminum oxide belts makes them perfect for deck refinishing.

Silicon Carbide Sanding Belt

Due to the sharp yet brittle nature of silicon carbide belts, they are not suitable for high-pressure grinding. Instead, they are perfect for sanding smooth surfaces like ceramic, glass, marble, and the likes. They are also available in 24 - 400 grit sizes.

Garnet Sanding Belt

This is another type of sanding belt that is notorious for its brittleness. Of all the types of sanding belts, this one produces the smoothest finishing without leaving behind abrasive scars. It may not be the best option for sanding hard surfaces, but the smooth finishing makes it ideal for polishing tasks.

Changing the Sandpaper on Your Belt Sander

You should replace the sanding belt on your sander as soon as it begins to wear. The belt replacement can be quite tricky if you're doing it for the first time.

Release the Belt Tension Lever

Firstly, locate the tension lever on this side of your sander, and simply pull it back to release the belt. The wheels should slowly move towards each other at the pull of the lever, causing the belt to become loose.

Remove Belt

The belt should pull off easily by now. Discard the worn belt.
Align the Sanding Belt

Make sure you are fixing a rightly sized belt and that it faces the direction. The belt should have arrow signs; these arrows should face the same direction as those on your sander.

Install New Belt

After the alignment, simply slide the belt into place and push the tension lever back in place. It's as simple as that.

Tips for Using a Belt Sander Correctly

A belt sander is relatively easy and safe to operate. The following tips can, however, improve your belt sanding experience.

Do Not Push Down on the Sander

A lot of beginners and amateur woodworkers make the mistake of pushing down on the sander. You should let the self-weight of the sander do most of the work. Some surfaces will require a little push, but you should never put your weight into pushing down on the sander.

Wear Protective Gear

It is very critical that you wear protective gear when sanding. Wear hearing protection as they can be very loud. These sanders come with dust collecting features, but they won't get rid of all the sawdust. Protect your eyes and cover your nose.

Unplug the Sander When Not in Use

Leaving your sander plugged in when it is not in use can be dangerous. You can easily forget to unplug; if you don't do so as soon as you turn off the machine. In particular, ensure that the machine is unplugged when changing the belt.

Keep Belt Clean

It is only normal to experience dirt buildup on the sanding belt after some use. You should clean after each use to prevent rough sanding work when next you grind with it.

Always Examine the Platen for Cracks

A platen that is properly aligned can easily snag the belt at any moment. Regularly check for cracks and replace them as soon as you notice any.

Can You Use a Belt Sander for Hardwood Floors?

Yes, you can use a belt sander when refinishing your hardwood floors. A belt sander is one of the reasonable options available if you are planning a DIY sanding operation. It is not the best sander for the job, as there are dedicated floor sanding machines that are made for this purpose. However, belt sanders are not so hard to operate and are faster than other handheld sanders because they cover more surface area.

Frequently Asked Questions

What sander should you use for deck?

There are several types of sanders, and a lot of those are suitable for deck sanding. An orbital sander is one of your best options if your deck is made out of softwood. However, the typical wide area of decks makes some of these compact sanders less suitable. A belt sander, on the other hand, will cover more area and make the sanding operation quicker.

Are belt sanders difficult to use?

They require some getting used to, but belt sanders are not so hard to operate. Compared to most handheld sanders, they can be larger and heavier. If you have never used one before, make sure you try it out on a suitable surface before using it on your main project.


If you are ever in the market for a good sander for deck sanding purposes, you should take a look at some of these options we have reviewed. If you are a beginner or an amateur in woodworking, getting the right belt sander will, without a doubt, be challenging. However, we have discussed some of the features and factors that are quite essential in any belt sander that will be used for deck sanding.
