Are you currently refinishing your deck and want it to look its absolute best?

A high-quality flooring sander is critical to the overall appearance of your deck and will make it look and feel more professional, rather than like your home improvement project is the aftermath of an unskilled homeowner.

Finding a deck sander that best fits your needs can be difficult on a competitive marketplace full of options. That’s why we’ve selected the top belt sanders for you. Once you invest in one of these, you’ll be happy to see the high-quality results on your finished project.

Benefits Of A Belt Sander For Decks

Sanding wood decks with a belt sander is the best option to prepare for deck staining or painting. Because these areas are completely flat surfaces that don’t have too many corners, sharp edges or narrow spaces, a belt sander with a wide belt is the best tool to cover the surface easily and efficiently.

Belt sanders are bigger than small or compact sanders, so they are perfect for large areas such as decks. They are also reasonably easy to manage and control if used properly and if you are working with a quality tool. They can also run for long periods of time without having to charge or rest, which is not always the case with smaller models.

1. Makita 9403 4in x 24in Belt Sander with Cloth Dust Bag

Makita 9403 Belt Sander review

The Makita 9403 Belt Sander

This sander is standard in the industry and a reliable choice that will get the job done. It has a 4-inch wide belt and a speed of 1,640 feet per minute. It’s built with a large front grip, so beginners aren’t struggling to keep it upright while using it. At a reasonable 13 pounds, this sander is not too heavy and easier to hold than bigger models.

It also has a large dust bag that has a 360-degree rotation designed to minimize particles blocking your sight while using the sander. Its electric cord is located on the top of the machine, which is a huge convenience – nothing is worse than using electric technology with one hand and having to hold a cord in the other. The Makita manufacturers ensure that this product’s cord is out of the way so that you can sand easily.

If noise is uncomfortable to you, this sander is the quietest of its kind. Although this sander is guaranteed to hold up for multiple uses, it also comes with a 1-year warranty. This sander is your best option as it offers all the important components at a decent rate.

2. Bosch OS50VC 120-Volt 3.4-Amp Variable Speed 1/2-Sheet Orbital Finishing Sander with Vibration Control

Bosch OS50VC Orbital Finishing Sander review

The Bosch OS50VC Orbital Finishing Sander

This is a heavy-duty, powerful sander that’s geared towards experienced users. Its 3.4 amp sander allows for a stronger sanding rate and maximum speed. Its enormous ½ sheet sanding pad is ideal for decks, allowing the user to cover a lot of surface area in a short period of time.

It’s strong but sturdy and automatically in control, with the ability to control its vibrations and move steadily. Its built-in suspension system exclusive to Bosch models makes this model easy to control and handle.

The Bosch OS50VC also comes with a Sheetloc clamping system that keeps the sandpaper perfectly in place. If you’re uncomfortable by its high speed, there is a speed dial that controls its strong movement and can accommodate any type of wood.

Although it doesn’t come with a dustbag, it has a built-in dust canister that collects particles efficiently and is easy to remove and empty when necessary. It’s a little pricier than the standard Makita 9304, but it’s one of the most efficient and trustworthy options available.

  • Extremely powerful
  • ½ Sheet
  • Professional
  • Low vibration

Hitachi SB8V2 Variable Speed Belt Sander review

The Hitachi SB8V2 Variable Speed Belt Sander

This is the most affordable model on the list that includes the minimum features necessary for a decent sanding job. It has a variable speed dial just like the Bosch model and an elastomer grip handle similar to the Makita 9403 to make it easy to hold and use.

Its small build makes it easy to control, transport, and use freely. It comes packaged with a large dust collection bag that’s easy to slip on and off. Besides its portable size, price, and standard features, this model’s biggest pro is its wear-resistant V-belt that is guaranteed to hold up for twice the service life of this sander.

At its base, it doesn’t come with a sanding belt, but it can be purchased with the belt as a combo deal for an incredibly low price that’s still more affordable than the other options.
