Best Sander for Deck 2021 [Updated List & Reviews]

Sanding is a difficult task, and if you are thinking of sanding a huge deck by hand, that will be exhausting. To save trouble, you should invest in some good quality sanding machines that can take care of your deck and help you with other wooden projects. Maintaining a deck is pretty expensive, so doing it yourself is always a good idea. If you were thinking the same, then welcome aboard. Here we will recommend some of the best sanders for your deck so that you can look at their specifications and functions to figure out what you need. This might be a long read, but we have tried our best to make it straightforward so that you do not feel like wasting time here.

Different Types Of Sanders For Woodworking

There are a variety of sanding machines available in the market. We will not be wasting your time discussing every single of them. However, we will discuss some of the famous, versatile, and best sanding machines for the deck here. They are-

Belt Sander

The belt sander is a device run by electricity with an abrasive coated belt that rotates and sands the surface. Belts are mounted on two cylinder-shaped drums. When the electric motor runs, the belt gains speed. It is one of the most common types of sanders available in the market. These come in different price ranges so that everyone can afford one in their budget.

Random Orbital Sander

The random orbital sander has round discs with sandpaper attached to it. They are portable, versatile, and lightweight. It has two types of movement, like revolving in a circular motion while vibrating in a circle. It creates a swirl-free polished look while working. Random orbital sanders help smooth or polish surfaces.  

Wood Floor Sander

The wood floor sander is usually a big and heavy sanding machine that commercial users mostly use. Usually, drum, planer, sheet, or orbital sanders are the ones they use for sanding decks. These are quite heavy and hard to move from here to there. Some of them might weigh over 100 pounds or so. They are extremely powerful and can damage the wooden surface if not handled by a professional.  

Sheet Sander

These sanders have a flat surface that can take belts of 9×11 inch sandpaper. This means that the sander can cover large flat areas. Interestingly, the sander uses tiny orbital vibrations to sand down surfaces to sand a wooden deck from any direction quite effectively. 

Confused About The Sandpaper?

There are tons of sandpapers to choose from to sand your wooden deck. But the question remains, are they all effective, or will you just be wasting your money? If you are new, make sure to research first and find the sandpapers that are especially suitable for wooden surfaces because these sandpapers use natural abrasives that work well to remove stains and uneven materials. Another important part is deciding the grit of the sandpaper you will work with. This depends on the type of work and the type of wood you have on your deck. You can start with 80 grit sandpaper to remove materials and smooth out the surfaces, and if some are still left, you can go over with 150 grit sandpaper. These sandpapers will ensure there are no rough spots so that your deck is smooth as butter. 

Tips For Sanding A Wooden Deck

Sanding a wooden deck might sound easy, but it is not. You could think that all you have to do is get some sanding machines and sand away. But that is not the case here. Before sanding any wooden deck, there are a few things that you need to keep in mind. Firstly, you need to consider power washing the deck. You usually need to power-wash the deck every year to get rid of any dirt build-ups or staining. It is necessary to power wash before sanding because the wash might cause the wood grain to rise and uneven the deck. In that case, you need the best sander for removing deck stain to prolong its longevity. When you sand the deck, you can make it even again to end up with a smooth deck.

Secondly, you must check the deck for any nails and screws that can cause problems when using your sanding machine. Countersink all those nails and screws with a nail punch for a safe workspace.

Lastly, make sure you sand the railings properly. When you first look at a deck, the first thing you notice is the railings. If you do not sand them properly, it will seem like the whole deck has been sanded poorly. So ensure that the railings are well sanded, and all the splinters have been taken care of. Use your hand to sand difficult corners that your sanding machine cannot reach. 

Buyer’s Guide For The Best Deck Sanding Machines

Sanding a deck is not an easy task. It takes a lot of time, dedication, and effort. If you are not hiring a professional for this job and thinking about going on your own, then make sure to go through the buyer’s guide to know the dos and don’ts. Here we have discussed all that you need to keep in mind before buying a sanding machine. 

Sander Type

Choosing the right type of sander is very important in this case. To work on a deck, we will suggest you go for the belt sanders over orbital sanders. These sanders are perfect for refinishing with their speed and powerful motor. Some might recommend the random orbit sander, as they are lightweight and attractive. But they work in a  controlled manner to give a precise finish which takes a lot of time to cover a large area. 

Dust Collection

If you have ever sanded anything, you know how messy it gets. Sanding a big area like a deck can create a lot of dust that can cause severe health issues. So it is essential to have a dust collection system with the sander. However, even with a dust collection system, you still need proper precautions like masks and safety gear. The dust collection system will gather all the dust in a bag rather than spray it around the workspace. It helps to keep the place neat. A deck is a large place that will create a lot of dust while working with a sander. To avoid that, you can attach the dust port with a vacuum hose so that it can suck down all the dust and keep the environment clean. Make sure the sanding machine you are buying supports attaching a vacuum hose. 

Corded or Cordless?

Here is another thing that confuses people. They do not know whether they should go for the corded sanders or the cordless ones. No worry, we are here to answer all your questions. We suggest going for the corded sanders if you work on a large wide surface like the deck. The cordless sanders use batteries instead of electric power. They might be portable, but they are not suitable for these works. You will get tired of changing the batteries frequently and spending money over it while the corded ones will need nothing and work for constant long hours. 

Noise Level

Another necessary thing to look at is the noise level of the sanders. The sanding machines create loud noises, which is uncomfortable. There are two solutions to this. First, you can invest in good quality ear protection that will go over your ears to protect them from noise. They can get a bit uncomfortable to keep on for long hours. Secondly, you can spend extra money to get a sanding machine with lower decibels, meaning they create less noise. We suggest getting a sander that generates low noise so that you can have fewer angry neighbors.  

Price

You will not have to spend an enormous amount of money behind sanders to get the right one. There are tons of sanders available with different features and price ranges. Some have the same features but offer a budget-friendly friendly price and also perform well. Comparing the prices and functionality can help decide the best one. If you buy a sanding machine to only sand your deck and for no other purposes, do not go for those with fancy features. Look for those that are good in power and speed and can work for long hours. 

Speed Settings

Some of the sanders come with a fixed speed, and some come with a variable speed option. The speed depends on what type of work you are going to do. High speed is helpful to sand out the top layer of the deck, and then you can lower down the settings to get an even smooth surface. The variable speed dial controls the speed of a sander. It can come in handy when you work on the railings of your deck.

Things To Keep In Mind Before Buying a Sander For Deck

Before sanding the deck, ensure that the deck is fully dry. It has to stay dry throughout the entire process. You must avoid sanding it if it is even slightly moist or damp. Check on the weather before starting to work. Still, if the weather hits hard, you have to wait till the deck dries completely before continuing the work. 

Safety Issues You Must Know

You need to read out the safety instructions before using any electronic machines. Here you will have to take the exact safety measurements when working on a small wooden project at home. A large area like a deck can create a lot of dust which can enter the lungs and eyes and cause irritation. Moreover, some chemical coating on top of the deck also mixes with the dust and enters the body. To prevent this, you will have to wear a protective mask or eye-protecting gear. You might also consider getting some hearing protection to save your eardrums from the loud noise of the sanding machine. Lastly, try to get some knee pads to protect your knees, as you will mostly be on your knees while working on the deck. 

What is The Best Sander for Decks? Top 10 List

If you are thinking about sanding your deck, you need some tools to help you with that. It is not possible to sand the whole deck by hand all by yourself. Here are some of the best sanders that are suitable for the decks for you to check. There are sanders of different brands, types, sizes, and functionality. We have chosen the most popular ones that had the support of satisfied customer reviews. Moreover, we have also added the pros and cons, and specifications to ensure you know all the details before purchasing any sander.

FAQs

Is it better if I sand or power wash the deck?

If your deck has a splinter, rough edges, or cracks, you can sand the deck first and then power-wash it. However, if it has moss, mold, or other things growing on it, the deck will need some treatments for that. 

Can I use floor sanders for sanding my deck?

Some homeowners prefer buying a floor sander for their deck. However, this is not that of a great idea. The floor sanders are suitable for flat surfaces only, and the deck is usually slightly curved. So it will not be able to do even sanding. 

Which grit sandpaper is suitable for the deck?

For the main deck boards, you can use 60 or 80 grit sandpaper and on the handrails, try to use 80 to 100 grit sandpapers. Ensure you have a good dust collection system that will not let any dust settle on the newly sanded surface.

Do I need to wash the deck after sanding?

Yes. You need to clean the deck after sanding it. There are some deck cleaners or deck wash that help to lift dirt from the deck surfaces. 

What happens if it rains while sanding the deck?

The deck needs to be dry when you sand, no matter what. If it is not completely dry but moist or damp, you cannot work on it. So if it rains in the middle of your work, you will go to step one phase, where you dry the deck thoroughly then start all over again. So you need to acquire the right sander for the outdoor deck.

Should I sand a deck before oiling?

If you own a deck and want it to stay good as new for a long time, you will have to sand and oil it regularly. Before oiling, the deck must be smooth and clean, and free from all kinds of debris. If it has splinters, cracks, or rough edges, you will have to sand it down and make it smooth again. 

What happens if I skip sanding and go straight to staining?

If you skip sanding, the stain can highlight imperfections like scratches and bumps in the wood and look unattractive. The purpose of sanding is to smooth out the surface so that the stain comes clean and the deck looks polished and stylish.
