KNOW WHAT TO LOOK FOR The Best Sander For Deck Refinishing

Choosing the right sander means knowing the essential features and factors needed to have efficient performance. Here are the common things you need to look for in choosing the right model.

1. Sanding Area

The sanding area of the unit is dependent on the type of wooden deck you are going to work on. If the deck has several edges and curves, then your sander must be versatile enough to work on those various surfaces.

2. Sander Type

You have two options for this: belt sander and an orbital sander. For deck refinishing, we would highly recommend a belt sander because it has more power and speed.

In contrast, orbital sanders are still functional and more inclined to control and precision works. The setback of an orbital sander is its lack of power and a small sanding area. This model is best used for sanding intricate and smaller wooded areas.

3. Power Source

Here you have two options, that is, battery-operated and corded ones. The corded electric type provides better power but lesser portability. Its portability is dependent on the length of the power cord. In contrast, battery-operated types are highly portable but has lesser power and operating time. The longevity of use is highly dependent on the battery capacity used for the unit.

4. Dust Port Extraction

Sanding works to create a sufficient amount of dust particles. For convenience, choose a model which has a built-in dust port extraction to readily absorb dust particles created during the operation.
