What is a deck sanding machine?

best sander for deck refinishing

A sander can be defined as a power tool that is usually used to smooth (or sand) surfaces. Sanding is usually done by abrasion and using sandpaper. The sandpaper is attached to the sander and then a mechanism that moves it rapidly is contained within some housing that hold or fix it to a workbench.

Normally, sanders for decks are powered by electricity. However, others like the ones used in auto-body repair are powered by compressed air. Sanders come in different types depending on their application. It's not the same sanding a deck than sanding for removing old paint or sanding furniture

Major types of sanders

Flap sander

Also called a sanding flap wheel, it’s shaped like a Rolodex and is used on hand-held drills or bench grinders. The sander is used for smoothing curved surfaces.

Belt sander

This is a stationary or hand-held sander.

Disc Sander

Mostly implemented as a stationary benchtop tool and has a replaceable and circular sandpaper. It is turned by compressed air or electric motors.

Orbital sander

The orbital sander is a hand-held tool and vibrates in tiny circles called orbits. It is mostly used to fine-sand or remove little materials. It can also be used for sanding drywall, however a drywall sander is recommended for this task. 

Wide-belt sander

This is a larger sander, and its concept is similar to a planer although it is much larger. This sander uses a rather large belt head and is used to sand large surfaces. The wide-belt sander is mainly used for large surfaces like cabinets and other larger furniture.

Drum sander

A drum sander is a large tool fitted with rotating sanding drums. The product is designed for larger surfaces finishing.

Stroke sander

A stroke sander is designed for large productions. It utilizes a hand-operated platent fitted on a standard sanding belt in order to apply pressure. It is used for finishing cabinets, doors, tabletops, and other large surfaces.

How to Select power sanders for decks

For maximum productivity and efficiency, you have to settle for the best sander. It is a non-negotiable situation as you will also be looking for a tool that gives you back the value for your money. It is, therefore, critical that you are vigilant enough and open up your eyes and ears for better offers.

The following are some of the things you should consider when buying a deck sander:

Consider your needs

The foremost factor to consider is why you are buying the sander. Ask yourself whether you need a tool to help you to sand rough surfaces or to dimension your workpiece parts. You should also know beforehand whether you need a product for specific surface finishing, targeted material removals, or even both.

Once you identify your needs, it will be easier to settle for the right one. If you cannot settle on one, a professional salesperson can advise you on the tool that fits your needs.

Machine type

Sanding machines come in all types and are more than you can go through at a go. You should, therefore, be armed with a short list of the machines you would choose from. Also, remember that salespeople will have their opinions and could sway you into buying one that won’t help if you do not have one in mind.

Head type

Next, consider the head type. There are four types: wide belt, brush, knife or planer, and orbital. Depending on your workpiece and the needs, you should be able to choose the right head type. Better yet, research the applications of each head and identify yours before heading to the shops.

New or used?

Depending on your budget and needs, would you settle for a used or new sander? This is a question only you can answer. Before heading out, you should be decided on what your pocket can manage and settle for that.

What is your budget?

This is the most important aspect of any shopping. You should not leave your house with a blind eye and a blank list, especially if you are operating on a tight budget. While you understand that most expensive tools are considered better, you should not overlook the cheaper ones.

Also, you should understand that a cheaper tool does not always guarantee good services. Some tools compensate their low prices by serving you only for a short while and then become useless.
