Gloss Up Your Wooden Deck With The Best Sander For Deck Refinishing

A wooden deck in the front or back yard gives an earthly ambiance. However, maintaining one is not a piece of cake but neither is it the hardest job in the world. You can always give a smooth finishing to the wooden surface by a utility machine known as a sander.

In case you require such a sander, this article will help you find the best sander for deck refinishing. Let’s take a look.

Buy the right tool for sanding: Critical points to keep in mind before sealing the deal for a deck sander

Dust Collection Features

You don’t want all the dust from sanding flying here and there. For this reason, say yes to only that sander which has a dust collecting bag or a vacuum deck cleaner attached for sucking the dust. Dust can be harmful to your respiratory system.

Speed Settings

Almost all of us have full energy when we start a project so we are in a fast and furious mode to get it finished. Similarly, at the start of sanding, you might want to work fast over the flat wood. But as time passes by and the more intricate parts of the deck start asking for sanding, you would want to slow down a little bit.

Therefore, consider a sander that has a speed variation controller installed in it.

Multi-Functional Sanders

Along with grit papers for sanding, some sanders have polishing features as well.

Noise Level

You don’t want your eardrums deaf and your neighbors yelling when you’re are refinishing your deck. Therefore, look for a lower-decibel sander.

Power Options

Sanders are usually available in two types regarding power:

  1. Electric-powered sander:  the cord in an electric-powered sander maintains a consistent supply of power. However, the managing of all the extensions and cables might get a little messy.
  2. Battery-powered sander: their main benefit is that they are portable and don’t require extensions or electric outlets.

Sanding area

The flat wooden surface requires a sander with power and speed. However, a deck with corners, railings, and intricate design asks for a versatile sander that can cater to the needs of the deck.  

Sander type

Sanders come in two types:

  1. Belt sanders: they are steady, sturdy, and fast.  These are highly recommended for sanding projects. 
  2. Orbital sanders: they are designed for precision and control. They don’t have the power and ability required for sanding large wooden surfaces in a shorter time. They are aesthetically pleasing nonetheless. 


Check your budget and keep in mind the requirements of your sanding project. In case you need a sander for your deck only, then you need not spend a lot of money on it as you’ll be using it once in a blue moon. If you are considering a sander for some other projects as well, you might want to spend some extra pennies to get a sander with extra features.
