Things To Consider When Buying A Sander For Deck

There are different types of sanders on the market, and there are several factors you need to consider in order to pick the best sander for your deck shine.

The following are some of the vital factors you need to put into consideration before buying:

Sanding Area

Before you set out to buy a sander, you need to ask yourself what type of deck you want to use the tool on. If your deck has variable corners or surfaces, we highly recommend you go for a versatile sander that can work on all the surfaces and corners.

Nevertheless, if you have a very flat deck, then your primary focus should be on power and speed.

Size

The size of a sander is also a very important factor to consider. When it comes to size, your focus should be on the size of the pad instead of the size of the model itself.

The wider the size of the pad, the more surface area it is likely to cover. Also, you should keep in mind that random orbital sanders are a bit difficult to get into corners.

On the other hand, belt sanders are a bit heavier and bulkier, so you should get ready for a little muscle exercise when using this tool for a long period.

The Power Of The Motor

If you want to know how strong the sander is, you should measure the size of the motor. The motors of all the sanders on our list are measured in amps.

For handling deck jobs, we recommend you go for a sander with nothing less than 3 amps. Anything less than that might result in more work time.

The Speed Of The Motor (Variable Speed)

The speed of the motor will also play a major role in the efficiency of your job and how much time the sanding session will take. Decks have different surfaces, as such, it would be if you go for a sander with variable speed control.

With this option, you will be able to adjust the speed of the machine to match the tenderness of the deck’s surface.

You would need high speed for the floor of the deck. However, a lower speed will do the job for the banisters. A single-speed control can damage some areas of your deck if you are not very careful.

However, single-speed models are much cheaper. In all, we highly recommend a variable speed model.

Dust Collection

Sanders generates a lot of debris and dust while in use. This is why many sanders come with dust collection systems. However, some are more effective than others, and you surely want to end up with a very effective dust collection system.

We highly recommend you go for a sander with a built-in dust collector, as they are more effective and keep your workspace free of dust and debris.

Conclusion

We hope our top recommendations and buyer’s guide will help streamline your decision-making process. Our top recommendation for the best deck sander is the Makita 9403 4” x 24” Belt Sander because it comes with a pretty powerful motor and great sanding speed. The belt size is also large, and it will cover a large surface area, making your job easy and quick.
