However, beginners are often unaware of the functionality of these sanders as well as the sanding process.

Tools Required for Sanding
Deck sanding can be a hectic task especially if you lack proper tools and equipment for sanding. With appropriate accessories, you can reduce the time required for sanding to a great extent and achieve the desired results without compromising on any aspect.
However, over the years, we have observed that the majority of the users are not extremely familiar with the appropriate sanding tools and their functions and often do not utilize them wisely. Therefore, we have included various pieces of equipment that can be used for sanding.
The first and foremost requirement is the hammer. Similarly, you can also use drills as an alternative to large projects that require additional time and effort. Both these substances have their own functions that reduce the burden on you. The basic task of the drill is to make holes and insert screws into the desired area.
Similarly, a hammer allows you to knock down any loose nails or insert new nails into the wood to secure it properly. We highly suggest using hammers that are made up of fiberglass core because of their high durability and enhanced sturdiness.
A power washer is essential in preparing the wood for sanding. It is used to improve the quality of wood and increase its suitability for sanding.
In most cases, the wood that has been power washed before sanding displays better results than the one that is not pre-treated.
Belt sanders are specialized tools that perform the actual sanding task. These are characterized by high performance and time efficiency and are generally recommended for large areas that are usually difficult to sand.
There are other types of sander available in the market as well, each having its own specifications. However, belt sanders are most suited for sanding decks because of their top-notch attributes and remarkable abilities that make them stand out among others.
Steps for Sanding a Deck Using Belt Sander
After you have prepared all the required tools for sanding, the next task is to sand the deck itself. Below we have compiled a brief step-by-step guide on how to use a belt sander on the deck for your convenience. So, keep reading the article if you want to know more about the sanding process.
Step 1: Washing the Deck
As mentioned earlier, power washing is highly useful; before the main sanding activity. It prepares the wood and leads to better results. Washing the wood before sanding can help you view the splinters clearly and eliminate all such problems during the sanding. For this purpose, we suggest keeping the pressure of the washer between 1000 to 2000 PSI for best results.
It will not only help you to soak the wood better but will also wash out all the debris and dust that might have build-up on the wooden surface over regular use. Similarly, this optimal pressure also prevents the washer itself from getting damaged and also protects the deck as well. High pressure can easily damage the deck which can lead to future issues. Once you have washed the deck, examine it carefully and look for any cracks on the surface for further treatment. Also check out how to use a belt sander on hardwood floors?
Step 2: Preparing the Deck
Once the deck has been washed, wait for 48 hours before it dries completely. After all the moisture has been evaporated, examine for any loose screws or nails on the deck. Use a hammer or drill to secure them properly before proceeding with the next step.
Step 3: Sanding the Deck
Now it is time to move towards the actual task. We suggest sanding in a downward motion on the exterior surface to achieve a smooth finish. Moreover, for sandpaper, we suggest staying between 60 to 80 grit as it will offer you the best staining output. Using grit higher or lower than this can affect the staining in the long term and can negatively impact your overall result.
As mentioned earlier, the belt sander is mostly recommended for the job because of its ability to quickly sand rough areas. We also suggest sanding the small areas and piles of wood to complete the task as quickly as possible. Also, if you are a beginner make sure to adjust the speed and power of the sander according to your abilities in order to control it properly.
