Buying Guide for the Best Sanders for Deck

buyin guide for deck sanders

Planning to buy a new sander from the long list of best sanders for your deck? Or, after inspecting your deck, do you think it is in dire need of sanding? Here’s a thorough guide that will help you determine which one is the best deck sander for you. Let’s look forward to a detailed list of all features that are a necessity.

Type of Best Sanders for Deck

There are a few types of best sanders for deck, four to be precise –

Random Orbit Sander

A random orbit sander is equipped with rounding pads. It can reach tight spaces, is also more portable, and leaves a fine finish. 

Sheet sander

A sheet sander comes along with sandpaper and is perfect for flat surfaces and will be one of the best options for a wood deck.

Belt sander

The best belt sander has two cylindrical drums attached to the abrasive belt. With this, you can trim, sand, or cut your deck to get a smooth finish. 

Commercial deck floor sanders

Finally, commercial floor sanders are usually for large decks and the best option for anyone with a good experience.

In this case, an orbital sander should be your top pick from the list of best sanders for deck. That’s because decks that count as softwood are prone to gorges. It is beneficial to use an oscillating or orbiting sander to get the best results. With these, there are a very few marks left on the surface. Also, it offers more sandpaper contact. Thus, it results in an even surface as more material is removed. In addition, they are very easy to control. 

Dust Collection method

None of us want to clean up loads of sanding, dust, and scrapes after getting finished with work. So, it is always best to ensure that your sander has a dust collector. It can be in-built or with a separate dust bag. But, I would always recommend an in-built one, because it can automatically collect dust in a canister which can be emptied later.

Also, another great feature while choosing from the best sanders for your deck would be a microfilter trap system. It traps the tiniest of particles. You’ll also need a dust-sealed switch to secure the dial so no dust enters the machine.


Mostly, there are best sanders for deck with a really high speed or low without any way to regulate it. The best way to go about this is to only purchase a sander with a variable speed setting. This switch allows you to change the settings as per your sanding measures. So, you can use it for soft materials and on a rough surface. The speed also depends on the power. The higher the power, the better the speed.

Portability, Compact Design, and Comfort

Try to pick a lightweight and easy-to-transport sander. If you have a smaller workplace, it would be best to get one that is smaller in size and can be stored in a cabinet easily. Plus, see to it that it has an ergonomic handle. For instance, it will have a rubberized over-mold to decrease vibrations and give you a soft and secure grip.

Noise Control

Working with a lot of noise in the background can be a headache. Also, loud noise for a prolonged period can cause ear damage. So, either purchase good quality earplugs or a sander with less or better no noise. 

Power Source

If you have to move your workspace often to places that might not have a power source, it is advisable that you buy a cordless or battery-powered sander. You can charge it overnight and use it during your work hours. However, sometimes cordless deck sanders have low power. They can be used for smaller projects, though. If you have a proper workspace, you might as well go for a corded one.


Doubtlessly, price is an important factor while buying a sander. Before you buy the sander, make sure that the rates are reasonable for all the features and attachments it offers. You don’t want to buy an overpriced sander with fewer or no unique features. But, also do not buy a low-quality sander at a cheap price; it will not be of any use in the long run. The price can be as low as $52 or as high as $350.


Check the size of the motor if you wish to know the strength of the sander. The size is measured in amperes. The most reliable sander is the one with a 3 amps motor. When you have a powerful motor, you can finish the job easily.

Precautions and Protocol to follow while sanding

Refinishing a deck is the same as sanding any other wooden material. There should be some safety rules to keep in mind in order to reduce any risks or damages.

Firstly, sanders can cause loads of dust, which can be either inhaled or get into your eyes. This situation will only cause unnecessary problems. Hence, the best solution is to wear eye protection gear like a dust mask and clear glass. 

Another required addition should be earplugs or any other noise-canceling device. Often these sanders produce loud sounds that could cause irritation and slow productivity.

Useful Tips

These are some crucial aspects to consider prior to investing in a sander. If you follow this guide, you most certainly will find one from the best sanders for deck. 

Remember to make sure your product is an item of longevity, quality, and a good investment in general. You can simply rub a few coats of boiled linseed oil to make this unique tool look new. It could also possess features that make it appropriate for multi-tasking. So, it could be used for other purposes when you need it. 

Also, follow correct instructions while sanding your deck to obtain ideal results and a spot-on finish. Also, try to use gloves to absorb the vibration.


While choosing the best sanders for deck, there are a lot of things to take care of. Right from variable speed features to its ergonomics. One main factor to consider is power. You need a very effective sander for sanding the deck. According to my research, the vote in this category goes to Makita 9403 4″ x 24″ Belt Sander. It will certainly make your deck look new and tidy.
