Top 8 Sanders For Deck Refinishing
1. Makita 9403 Belt Sander For Deck Refinishing
Our top pick is Makita 9403, which is simply the best model for sanding wooden decks. This belt sander for deck machine is fast and easy to control, but it is heavy at a weight of 13 pounds.
Makita 9403 comes with 4 inches on the belt width and works at a 1,640 feet per minute speed. It has a wide grip that makes it even easier to use, even for beginners. With an inbuilt dust collection bag that swivels at 360 degrees, it stops all the particles that can disturb you while sanding.
One of the most convenient features is the location of its power chord, which is at the top. It’s irritating to move the sander with one hand and use another to hold the power cable. The manufacturers understood the same and kept the cable out of your way.
The only disadvantage of 9403 is its price. If you are a professional, you will be more than happy with the price tag, but it may not be acceptable for a one-time project.
- Fast and powerful
- Wide belt
- Quiet (84 decibels)
- Comfortable and solid grip
2. DEWALT DWE6423K Random Orbit Sander
If you are looking for a sander for some weekend work or a one-time deck sanding machine, DEWALT DWE6423K will be a great option. A 3 amp motor under the hood is powerful enough to work on any kind of surface, even the hard ones. Moreover, it has a fine dust capture cabinet and is cost-effective.
The ability of DWE6423K to deliver a smooth and precise surface is enough for any wooden deck refinishing. Moreover, it can complete the job in half time as compared to other orbital sanders. Huge productivity bonus, that is, right?
Time-saving as well. The orbital floor sander also has air vents around the motor for air circulation, ensuring that it is not overheated during prolonged sanding hours. There is no need to mention that if the motor is not getting overheated time and again, it will last longer.
Another attractive feature of this model is its speed control dial. You can easily reach the dial while working to change the OPM (orbits per minute) from 8 000 to 12 000.
The feature comes in handy while you are working on different materials of variable densities. For example, a top OPM of 12 000 works well to provide a smooth finish, while an OPM of 8 000 is good for rough surfaces.
If you prefer an orbital sander over belt sanders, then you will not hold any grudge over DWE6423K.
- Variable speed dial
- Reduced vibration
- Difficulty in connecting the dust bag to external air vacuum
3. SKIL 7510-01 Sandcat Belt Sander For Deck Refinishing
The sander from SKIL gives the best value for money and the performance you will appreciate. If you are looking for a 3-by-18-inch belt sander for the wooden deck, SKIL 7510-01 is one of the best and cost-effective choices.

Once the pressure reaches the appropriate level, an indicator lights up to let you know that your hands are forceful enough to do the job. This feature sets the sander apart from the other models.
The sander has a micro-filtration mechanism to capture even the finest dust particles. However, the dust collector seems to be the problem as it is facing some difficulty staying connected, which can be a distraction while sanding a large wooden deck. Another considerable disadvantage is its narrow belt size of 3 inches that may take a little extra time for a job than expected. If time is the key, then you should look for a model with a wider belt.

Types of Desk Sanders
Several different types of desk sanders are available, but we have described only the versatile categories.
Belt sanders: An electric device having an abrasive coated belt is sold as belt sanders. The abrasive belt is mounted on two cylindrical drums and is rotated by an electric motor. Using the rotating belt, they can sand, level, or trim both round and flat surface areas.
Random orbit sander: With a round sanding pad, random orbit sanders are one of the most versatile portables electric sanders to own. Its round pad has two different movements – it vibrates in mini circles and also revolves in circles. As the best random orbit sander has two simultaneous movements, they eliminate swirls that other sanders tend to leave behind.
Sheet sanders: Specially manufactured to a flat sand surface, sheet sanders work once you enter 9×11-inch sandpaper in the device. The sandpaper is held against its flat square pad by two spring clamps. Its pad vibrates in tiny orbits, which allows you to move the sander in any direction.
Commercial wood floor sanders: Available at rental outlets, orbital or drum sander is used for large wooden decks.
Because of the heavy weight, such sanders are hard to transport but work perfectly for not warped or cupped areas. On the other hand, drums sanders can remove woods at a very high rate, so they may harm the household desk if used by a beginner.
How to remove sanding dust from wood?
You cannot apply the paint unless all the dust spread from the sander is removed. If dust particles stay on the deck and you apply the paint, it will look grainy and feel rough once you touch it.
All your hard work will be wasted just because of those tiny particles, and you will not see the perfection that you were expecting. So please follow the following process to get rewarded with the praising look in the eyes of your future guests or family members.
1. Vacuum thoroughly and wipe: Clean the deck surface using a vacuum cleaner fitted with a filter to catch even the finest of dust particles. Then, wipe the surface using a clean and dry cloth. Use a white cloth so that you can see the number of dust particles it is collecting.
2. Wipe the surface with a tack cloth: Purchase tack clothes from a nearby grocery store. Cut it into small squares and wipe it lightly over the deck surface. Keep checking the cloth after regular intervals and change one it is dirty.
You can also check the smoothness of the surface while wiping with a tack cloth. If you notice that threads of the cloth are snagging on the rough surface, get back to the sander and make it right.
3. Wipe it with denatured alcohol: You can end the dust cleaning process after wiping the wooden floor with a tack cloth. But, for best results, wipe it again with a clean cloth moistened with denatured alcohol.
Denatured alcohol will pick even the tiniest dust and evaporate quickly, so it will not leave any mark or discolor the floor. After this step, the process is complete. Now, you can move on to staining and sealing as soon as possible.
Tips for Sanding a Wood Deck
As we already spoke about the various types of deck sanding machines. Let us go through the process and some tips that will help while sanding your wooden property.
1. Pressure wash: The first step is the pressure washing of the deck. If the deck is made of softwood like cedar, pine, or spruce, use a wide wan and decide the distance between the wand and surface. If you see that the wood fibres are lifting as you wash the floor, stop right away. Take a hidden spot on the wooden floor to test the pressure and wand distance. After the wash, let the deck dry for a couple of days.
2. Prepare the surface: Check for every screw and nail. Use a nail punch to countersink every one of them; otherwise, they will damage the sander.
3. Sanding the board edges & deck surface: Make sure that you are not using the sander with any rough grit, as it can excavate the deck if it is made of any softwood. Wear safety glass and particle mask as the dust spread by the sander is hazardous if you inhale it.
For better comfort and ease, you can also use a hearing protector and kneed pads. Next, check the weather for rain. If it rains while you are sanding the wood deck or after sanding, then you will be back to level one. This means you have to wash the wooden surface and sand it again.
As explained earlier, you should use a belt sander as it will be convenient and fast. For removing existing paint or stain using an orbital sander, start with 60-grit sandpaper and go over again with sandpaper of 120-grit for a smooth finish. Apply medium pressure and check for the evenness as you move forward.
Use different sanding techniques depending on the surface of railings, deck area, and board edges. Sanding outer edges can be difficult, especially if you have a low bottom rail with a series of pillars. In the case of an orbital sander, use 60 to 80-grit sandpaper and take care of the evenness as stains tend to get absorbed easily into uneven surfaces.
4. Sanding the railings: One of the most important parts of the process is to sand the railing evenly as it is the most visible part where people generally focus. Moreover, it should be smooth, and there should not be any splinters left to injure any hands.
Use sandpaper with 80 to 100-grit, but do not stain such smoothness that stains cannot penetrate. Sand using your hands with sandpaper where the sending device cannot reach.
Buying Guide Of Sander For A Deck
Now you know the various types of desk sanders that can make your deck shine. Before you scroll down and check the top picks for the best sanders, we mention some tips that will help you choose the right model. The idea is to leave no room in your mind for any doubts. Let us begin.
Sanding area: We know that you want to sand the wooden deck. The question is, what kind of deck are you going to work on? If the deck has variable surfaces or corners, you need a versatile sander that can work on all of it. Otherwise, if you see that the deck is flat, then all you should look for is – speed and power.
Sander type: You will be working on a deck, so we recommend the belt sanders as they are powerful and fast. Orbital sanders look attractive, but they are built for precision and control. They lack the power and ability to cover big areas in a short time.
Power input: There are two types of deck sanders – wired and battery operated. Wired sanders have high ratings over battery-operated ones as the former are better to work for long hours. By chance, you have to buy a battery-operated sander, then look for those coming with Lithium-ion batteries.
Price: It is not necessary that you have to pay a high price for a good sander. If deck sanding is the only job you will perform with the sander, you may get a fine working model without paying a hefty price. All we mean is that you should compare all the features and prices, then make the purchasing decision.
Dust extraction: Sanders creates a lot of dust and debris while doing its job. It is better to have a sander that has an inbuilt dust collector. Otherwise, you will be the one who has the clean the area. Cleaning can be tiring. Above all, wood dust can create a lot of health problems.
Frequently Asked Questions
Should I sand my deck before staining?
Yes, it is recommended to sand and clean the dust particles before staining or painting.
Can sanding wood make you sick?
Dust particles spread while sanding can cause some serious health troubles, including allergic reactions and lung damage. Use a sander with a dust collection bag, or always wear a face mask or respirator while sanding.
Is sanding wood dangerous?
If you take precautionary measures, then it is not. Wood dust is a known human carcinogen that can cause irritation, breathing problems, and allergies. Use respirators and dust masks always while working on the wood.
Can you sand a wet deck?
No, you will not be able to. The sanders will not work on a wet surface. Let it dry for a couple of days if it is wet, then sand the deck.
What is the difference between a belt sander and an orbital sander?
A belt sander uses an abrasive belt 18 to 24” long and 3 to 4” wide. Unfortunately, few small belt sanders come with 14 to 16” long and 2-1/2” wide belts. As a result, belts used in the sanders are thick, last longer, and are costly.
On the other hand, an orbital sander, also known as a random orbital sander, works with a sanding pad or disc of 5 or 6 inches and different grits varying from 60 to 220. Dicks used in orbital sanders are cost-effective but need frequent replacement.
Overall, belt sanders are more powerful and work better than orbital sanders, but the former is difficult to control for beginners and can harm the wood if not used properly.
As we end, we would suggest using belt sanders, Makita 9403 is the best of all. However, if you want to use an orbital sander just for the sake of easy finish, then opt for DEWALT DWE6423K, which will give you the required results apart from its dust collection.
We hope that there are no doubts left about the sanding process or sanders. Happy sanding.
