Decks are built with high-quality lumber that can last for a long time as long as you keep up with its maintenance. One of the most important maintenance you’ll have to do on your deck is refinishing. You strip the deck of any previous finish before reapplying the desired finish. Stripping the deck includes cleaning, and sanding, among other activities.

Sanding the deck is the way to remove tough stains, finish, and sealants on the deck’s surface. Since decks have a large surface area, using sandpaper and sanding by hand is almost unattainable. Therefore, Sanders becomes quite important when considering the size of the surface. Preparing for deck refinishing requires assembling tools and materials, with sanders as the major tool for this purpose.

Reviewing sanders has helped us develop the best sanders for deck refinishing. We’ll be revealing our findings shortly, but first, you must realize needs vary, and these sanders all have varying strong points. This guide discusses sanders, buyers’ guides, and more in detail.

Buyers Guide: How to Select The Best Deck, Refinishing Sander?

Before you buy a sander for your deck refinishing project, it is essential to go through this checklist. The section contains vital factors when selecting a suitable sander for deck refinishing.

1. Orbital Vs Belt

Orbital sanders are often portable with great precision and control; however, they lack power. On the other hand, the Belt sander is big and powerful, with minimal care for control or precision. Belt sanders are often preferred for deck refinishing projects because of their insane power.

2. Deck Size and Features

This factor is less about the sander and more about the deck surface. First, you want to determine the surface area of the deck and its features. Large decks typically require sanders with enough power and a large belt to cover a wider area at a given time. Decks with many details will require great handling and precision sanders to handle these differences.

3. Price

Price will always be a huge determinant of the type of products you can buy. However, you don’t have to break the bank to secure a good sander, with several low-budget sanders proving great quality. Premium options, on the other hand, are expensive but typically offer many features to justify their prices.

4. Speed

Sometimes, high speed is not the answer for sanders, as some parts require lower speed levels. The advantage is in the variable speed level covering a wide speed range. Different areas on the deck may require different speeds to produce a clean result. Getting a variable speed sander where you can adjust its speed is a great idea.

5. Dust Collection

Consider the type of dust collection system in place for this sander and how effectively it reduces dust from the sanding. Some dust collectors need to attach properly, while others are too small for the task. You want to check the size and its fit before making the purchase.

6. Noise Levels 

How loud is the sander you intend to purchase? This is a question you should ask, especially if you’ll be sanding for a long time. You do not want to damage your hearing by working close to an extremely loud tool, nor do you want to disturb your neighbors. Check the levels of decibels it emits before making the purchase.


Here are short and quick questions about sanders for deck refinishing alongside their answers:

Q1. Do floor sanders work on decks?

Ans: Floor sanders are not ideal on decks as their size and weight will prove huge stumbling blocks to their use.

Q2. Does weight matter for deck sanders?

Ans: Weight matters less than many would imagine, as weight can also help to provide stability. However, extremely heavy sanders can damage the deck.

Q3. Orbital or belt sander?

Ans: The choice here depends on your needs, as orbital sanders have more precision and control and, as such, are great for small detailed decks. On the other hand, Belt sanders are powerful with little regard for control and are suitable for large plain surfaces.


Choosing your ideal deck refinishing sander may prove difficult without help. These tools usually sport powerful motors, among other safety and convenience features that make each sander unique.
