Makita 9403 is simply the best sander on the market for sanding any wooden deck. It is fast, quiet, easy to control, and weighs 13 pounds – really heavy. The sander is designed with a 4-inch wide belt that works at a maximum speed of 1,640 orbits per minute.  This, coupled with a wide grip makes sanding tasks easy and fun too.

Weighing 13 pounds, this sander for deck is by all means really heavy, right? But hold on, the weight need not be a red flag or dissuade you from purchasing it. On the brighter side, It makes the sander firmer, and controllable because you do not need to use a lot of pressure. The heavy design works well with the powerful 11 AMP motor to help you sand the entire deck fast.

Another top feature of this sander is the conveniently located power cord. Joining the sander at the top, the cord is perfectly positioned away from your hands so that you can concentrate on the sanding task at hand. The sander further comes with a large dust bag carefully constructed to rotate at 360 degrees so that it will block your view. The design further helps to seal and protect the motor from dust and other contaminants.

The sturdy design and durability of this sander did not surprise us at all because Bosch has made a name for quality. The sander has a rugged construction of die-cast aluminum that serves two purposes; enhancing its durability and reducing vibrations.

In addition to its powerful motor, the sander is notably versatile with its flush sanding ability that works close to vertical surfaces on three sides.

The SKIL 7510-01 is a powerful, versatile, stylish, and amazingly low priced sander. We found the price incredibly affordable considering its features qualify it for a higher price tag.

One of the most outstanding things about this sander is its pressure control technology. Unlike other sanders that allow users to guess the pressure to apply, SKIL 7510-01 has a warning system. When you apply a lot of pressure, it warns you to relax a bit — no need to waste your energy!

Another selling point of this sander is its auto-track belt alignment system designed to keep the machine belt centered. This implies that you can work with the sander without worrying it will slide to one end, which reduces overall efficiency. We liked the design because it also keeps the downtime as low as possible.

One of the key selling points of this sander is its ability to deliver smooth and precise surfaces fast. Its shorter height is particularly a plus because you are able to get close to the workpiece for better results.

We also liked the unique sander’s dust collection system. Its dust bag was designed after reviewing other models in the market, and it is awesome. Using just one hand, you can easily snap the dust bag into position after emptying to avoid wasting time.

For years that DeWalt has been in the market, its goal of improving its tools is manifested through creativity. In this sander, we noted the improved dust-sealed switch that helps to prevent dust ingestion. This is a perfect way to make the sander last longer.

Buying Guide

Now that you’ve read through our best sander for deck reviews, you are probably thinking about the best piece to pick for your situation. Do not worry because we got you covered here too.

Our buyer’s guide will help you to understand what to look for when picking the ideal piece. As a general rule: go for top performance and value!

Types of Sanders for Deck

Belt Sander

These are electric sanders designed to use abrasive belts to smooth wooden surfaces. The belt is wound on two drums and then rotated by a motor. As the motor rotates the abrasive belt, it can sand, trim, or level the wooden surfaces.

Orbit Sander

This sander is designed with round pads that make different movements to smoothen wood. The pads vibrate and revolve in circles to eliminate swirls on wood that other types of sanders often leave behind.

Sheet Sanders

These sanders are manufactured to smooth flat surfaces. The sandpaper in a sheet sander is held on flat pads and clamped with a spring. The pads vibrate in tiny orbits that allow you to move the sander in different directions.

Top Sander for Deck Brands

Another crucial consideration when buying a sander for deck is brand. If you want a high-performance sander for deck, it is advisable to go for the models designed by top brands.

So, here are the top brands in the market that have made names for their focus on quality and customer value:

Things to Look for When Buying a Sander 

Sanding Area

We know that your aim is sanding your wooden deck. But what type of deck is it? If it is designed with corners and surfaces that are variable, it is advisable to look for a versatile sander capable of smoothing all of them. But if the deck is flat and all that you need is smoothing it, simply go for top speed and power.

Sander Type

Because you will be working on your deck, it is advisable to go for belt sanders because they are not only fast, but powerful too.

Although orbital sanders can still do the job, it is important to know that they are designed for precision and control. They are simply not suitable when you have a large area to work on.

Power Input

Sanders can be broadly categorized into two, wired-electric and battery-powered. Wired sanders are more powerful and effective because they use electricity. If you opt to use a battery-powered model, at least, go for the one with lithium-ion batteries.

Dust Extraction

Sanders generate a lot of debris and dust as they rip the wood on your deck. Therefore, you should look for a sander with a reliable dust collection system.

This could be an inbuilt dust collection unit or an external dust bag. Some models are even designed to work with a vacuum cleaner for more efficient debris evacuation.

Price

Today, it is possible to get a high-performance sander without draining your entire bank account. Because of the high competition out there, many brands have pushed their prices down significantly.

But price should not be your sole deciding factor as most cheap models are likely to be less effective. Instead, you should compare the prices just like you do with other features. Then, aim at getting the best sander with the best features and affordable price tag.

Final Thoughts

It is easy to see why the above seven sanders for decks were selected for this review; they have enviable designs and creative features that make them highly regarded by professionals and DIY people. Therefore, no matter the model you select in our list above, rest assured of efficient sanding and value for investment. Always remember one thing: you should choose the sander for deck based on the intended use.

While we can vouch for each of the seven models we’ve reviewed (they are amazing, no doubt), our overall best pick is the Makita 9403 Sander for Deck. This sander for decks prides itself on quality construction, well-rounded features, and guaranteed performance. No matter what you would want in a sander, it is well packaged in this particular model!
