Can You Use A Floor Sander On A Deck? Deck Sanding Tips!

Is It Possible To Sand A Deck Using A Floor Sander?

You can use a floor sander on a deck. You will need to start by removing the old finish.

Make sure the surface is smooth and clean before applying a new finish.

If you are using an orbital sander, make sure it has been properly adjusted for your application.

If not, you may damage or scratch the type of wood.

Also be careful when sanding around windows and doors as they could get damaged if hit with too much pressure.

Sanding a wooden deck requires some skill and experience.

  • The first step in finishing any project involves cleaning up all of the debris from previous projects.
  • This includes cutting away nails that have rusted out over time.
  • Once this work is done, you should prepare the area where you plan to apply the smoother finish.
  • Remove loose dirt and other materials that might interfere with the final product.
  • Then remove any rough edges left behind after construction.
  • Finally, cut off any excess material so that there is no unevenness at the end of each board.

Sanding a wooden deck requires patience and practice.

Start small and gradually increase the amount of pressure applied to the boards until you reach the desired level.

What is the best sander to use on a deck?

The best type of sander depends on what kind of smooth finish you want to put on the deck.

For example, if you’re going to stain the deck, then you’ll probably want to use a belt-driven pad sander.

These types of pads are made specifically for staining decks.

They come equipped with different grits which allow them to do their job well.

However, if you just want to give the deck a quick coat of sealant, then you don’t really need anything special.

A regular drum sander would suffice. Just remember to keep the speed slow enough to avoid damaging the type of wood.

How to Sand a Deck with a Random Orbital Deck Sander?

Deck sanders are an essential tool for anyone who wants to refinish their entire deck.

They are used to smooth out rough and tight spots and remove old paint.

However, there are many different types of sanders and each has its own unique purpose.

There are two main types of sanders: orbital and random orbital.

The difference between these two types of sanders is that the orbital sander uses a circular motion while the random orbit sander uses a random motion.

Random orbit sander are often used to sand soft wood because they are able to get into tight spaces.

This makes them ideal for smoothing out cracks and crevices.

Orbital sanders are great for general sanding but they aren’t very good at getting into corners.

If you try to sand something like a window frame, you won’t be able to get into those hard to access areas.

To help you decide whether or not you need one of these tools, here are three things to consider:

1) How big is your deck?

2) What surface will it be covering?

3) Do you already have a power source available?

If you answered yes to all 3 questions, then you definitely need a random orbital sander.

Otherwise, you can always opt for an orbital sander instead.

You also need to make sure that you know how to operate the machine before using it.

Here’s everything you need to know about operating a random orbital sander:

Step 1 – Set Up Your Machine

Before starting, set up your machine by following this guide from Woodworking Network.

It explains step by step how to properly assemble your random orbitals sander.

Once you’ve completed setting up your machine, start sanding!

Step 2 – Start Using Your Sander

Once you’ve finished assembling your sander, take some time to learn how to use it.

There are several videos online showing people demonstrating how to use a random orbital sander sizes in action.

These videos should provide you with plenty of information regarding proper technique when using a random orbital sander so you can begin working right away.

Once you feel comfortable using your new efficient sander, go ahead and start sanding!

Remember to follow the instructions provided by the manufacturer as well as any safety precautions listed on the product packaging.

What grit should I use to sand a deck?

Grit is an abrasive material used to remove rust, paint, and other surface contaminants.

It’s also used to polish type of wood surface such as decks, furniture, and floors.

There are two types of grit commonly used for these purposes: steel wool and diamond dust.

Steel wool is a coarse grade of grit that has been formed into long strands.

Diamond dust is a finer grade of grit that consists of tiny diamonds.

Both materials are effective at removing surface contaminants, but there are pros and cons to each type.

For example, steel wool tends to leave behind more scratches than does diamond dust.

However, if you’re looking to create a smooth deck finish ready, steel wool may work better since it removes deeper layers of dirt faster.

On the other hand, diamond dust works best for polishing fine and actual finishes.

So which do you choose? That depends entirely upon what kind of look you want to achieve.

Here are some tips to keep in mind when choosing the appropriate grit to sand a deck:

• If you plan to stain the deck after finishing, select a coarser-grit material. This will allow the stains to penetrate deep enough to hide imperfections.

• For a polished appearance, use a medium-fine grit.

• To avoid scratching the surface, use a very fine grit.

Furthermore, don’t apply too much pressure while sanding or else you’ll end up marring the surface.

Can I use a belt sander on my deck?

Yes, you absolutely can use a belt sander to sand your deck.

In fact, many professional carpenters prefer them over random orbital sanders because they offer greater control.

A belt sander allows you to move back and forth across the surface without having to stop every few seconds to adjust the angle of the tool.

This means you get a smoother result overall.

The downside is that inline belt sander tend to be slower than random orbital finishing sanders.

They require less power and therefore produce lower RPMs.

As a result, this makes them harder to operate.

If you have access to one, though, give it a try. It might just become your favorite tool. 

How long does it take to sand a deck with a floor sander?

Sanding a deck takes anywhere from 30 minutes to 2 hours depending on the size of the project.

You need to factor in time spent cleaning up debris created during the refinishing process.

Also consider whether you’d like to add additional coats of polyurethane or epoxy resin before staining.

Finally, remember that some projects require multiple passes to ensure a uniform color throughout.

That said, most professionals recommend starting out with about 100 square feet per pass.

Afterward, increase the area covered by successive passes until you reach the desired coverage level.

Once finished, let the new coat dry deck wood completely before applying another layer.

And finally, make sure to wear protective gear when using a flooring drum sander.

It’s not uncommon for sparks to fly off the blade as it moves through pieces of wood.

These could burn skin and eyes, so always keep safety first! 

How often should I clean my floor sander?

You shouldn’t need to clean your floor bet sander unless it gets really dirty.

That said, cleaning it regularly helps extend its life span.

To keep things simple, wipe down the machine periodically with a damp cloth.

Use warm water in order to prevent overheating.

Don’t forget about the belts either; make sure they aren’t frayed or worn out.

Otherwise, you could damage the motor.

When possible, replace the belts before replacing the entire unit.

Do not attempt to disassemble the modern sander yourself.

Instead, contact a local repair shop for assistance.


Using a floor handheld sander on your deck isn’t difficult at all.

However, there are several factors which will affect how well it works.

  • First, if you’re working on an unfinished wooden deck, then you may want to wait until after installation.
  • Second, if you plan to stain the deck, then you’ll probably want to do so prior to installing any hardware.
  • Third, don’t use too much pressure while on two-step sanding process.
  • Fourth, avoid getting wood dust into your lungs.
  • Fifth, never work near flammable materials such as gasoline or oil.
  • Lastly, make sure to follow proper safety precautions whenever using a flooring sander around children or pets.
