Factors to Consider When Buying the Best Drywall Sander

When it comes to buying a drywall sander, there are several things you need to keep in mind to ensure that you get the best one. They include: 

Type of Project You Want to Work On

When buying the best drywall sander, the first thing to consider is the type of task you want to work on or the reason behind the purchase. 

You should ask yourself whether you want a drywall sander for professional work or DIY home projects. 

If you plan to move around with your drywall sander performing sanding tasks in various places, you’ll need a portable one. 

Asking yourself if you need the sanding tool for one-time use or several projects will also help you to quickly figure out the best drywall sander for your needs. 

Weight 

Drywall sanders come in varied weights, depending on their design and size. You will want to go for the lightweight drywall sanders as they are easy to handle. 

Keep in mind that lifting heavy materials for a long time can affect your health negatively unless you are an incredibly strong person. 

If you buy a heavy drywall sander, it will be difficult for you to use it efficiently, especially if you are a DIYer and just want to carry out some home sanding tasks. 

However, heavier drywall sanders can be a better option for professional jobs as they tend to be more durable. In this case, you don’t want to sacrifice sturdiness and performance just to get something light.

Lightweight drywall sanders with reliable build quality also tend to be expensive, and so you’ll have to strike a balance between price and weight as well. 

Revolutions Per Minute (RPM)

The number of RPMs a drywall sander can give also matters a lot as it determines how long it will take for you to get the job done. 

A high-quality drywall sander will higher RPMs will help you finish your sanding jobs within no time. 

At the same time, however, very high RPMs mean that your hand will have more pressure, and you’ll get tired easily. 

So, the best thing to do is to go for a drywall sander with an adjustable RPM rate for efficiency and ease of use. 

Flexibility

It’s also important to consider the flexibility of a drywall sander as you don’t want to work with a rigid tool that makes your work more complicated.

The best drywall sander should have a flexible head to ensure that it’s easy to work with when smoothening corners and curved spaces. 

With a flexible drywall sander, you won’t have to move in every corner you need to smoothen. This will help you finish your work quickly and get great results. 

Dust Extraction

When sanding drywall, a lot of dust is produced and can lead to health issues like nose, eye, or throat irritations.

If you don’t want to develop health conditions after using a drywall sander, you will want to go for the option that has a dust extraction feature. 

Drywall sanders with dust extraction may not eliminate dust 100%, but they collect up to 95% of the dust produced. 

The dust collection feature will protect you from dust and leave your room clean to save your cleanup time. 

Durability

While it’s not always easy to predict the durability of a product, the materials used and build quality can tell whether the drywall sander will last long. 

Consider going for a high-quality drywall sander to ensure that it can serve you for a long time. 

Of course, sophisticated and durable tools will not have a low-price tag, but they will be worth the cost. 

Sanding Discs Size

You should never overlook the size of the sanding discs in a drywall sander, as some manufacturers make non-standard-sized discs. 

This can create a problem when you want to replace the discs as you won’t easily find an ideal replacement in nearby tool stores. 

So, it’s essential to pay more attention to the diameter of the sanding discs for easy and convenient replacements. 

Ease of Storage and Maintenance

You may not have to use your drywall sander every day, especially if you are buying for your home enhancement projects. 

So, you need to ensure that you choose one with a good storage facility or easily fit in your available space. 

While all power tools and heavy machines require some maintenance, some are less maintenance hungry than others. 

If you want to work efficiently with your drywall sander, go for one that needs less maintenance and will still last for a long time.

Frequently Asked Questions

What is the Easiest Way to Sand Drywall?

The easiest way to sand drywall is by using an electric drywall sander. These sanders are efficient and deliver outstanding results. 

Drywall sanders are safe and convenient to use, and most of them come with dust collecting features to reduce your cleanup work. 

If you can find a drywall sander with adjustable RPMs, you’ll conveniently sand your wall faster or slower since you have control over speed. This will lead to a perfect smoothened drywall. 

What Grit Sandpaper Should I Use for Drywall?

The best sandpaper grit to use for drywall is 120 and 150. Sandpaper grit below 100 is too coarse and doesn’t work well on drywall. 

The higher the number of grits, the smaller the grains. So, grits beyond 150 are unsuitable drywall as they will barely smoothen the surface. 

How Do You Minimize Dust When Sanding Drywall?

There are many ways to minimize dust when sanding drywall, including the use of a drywall vacuum sander, wet or dry vacuum, wet sanding, and sheeting. 

The drywall vacuum sander work by sanding drywall and feeding the dust down the tube into a vacuum cleaner. 

You can use a wet/dry vac with a drywall vacuum sander to reduce the dust significantly. When using this machine, it’s essential to use a pleated filter instead of paper or foam for efficient results. 

Wet sanding can also minimize dust when sanding small areas of drywall. You just need to allow the drywall compound to dry, then use a wet sponge to rub away the compound. 

While sheeting will not reduce the amount of dust produced, it limits its dispersion to other areas and keeps it confined in a single area. 

How Many Coats of Drywall Mud Do I Need?

Generally, you need four coats of drywall mud, where one coat is for filling in the seams, and the other three are applied after taping. 

Nonetheless, the number of coats may vary, depending on the type of mud you want to use and the desired finish level. 

Why Does Drywall Mud Crack?

Drywall mud cracks easily when you use too thick coats. Thick outer coating hinders evaporation-based drying and makes the crack curing compounds crack. 

The best way to apply drywall mud is to start with a thick coat, then apply thinner layers after taping. You should also ensure that the first coat has dried overnight before applying more layers. 

If you notice that your drywall mud has started cracking, you shouldn’t apply more mud as this will worsen the situation and weaken the building. 

Should You Sand Inside?

Yes. You can sand inside, but you’ll need to prepare for a lot of dust and find ways to minimize it. 

Drywall sanding produces much dust that will not only leave your house messy but can also be harmful to your health. 

So, if you plan to sand inside, you should prepare well for the task. Buying a drywall sander with a dust collector can be an efficient way to sand inside without creating a big mess. 

How Can You Protect Yourself from Sanding?

You can protect yourself from sanding by wearing a protective air filtration mask and collecting dust as you work. 

You can also use a portable air cleaner, especially if you are sanding indoors, that can capture dust particles and keep you safe. 

What Happens If You Don’t Sand Before Painting?

If you paint before sanding, the results won’t be great. Most poor paints result from painting a wall or dry surface without sanding it. 

Your paint may also start peeling off in the future, and you won’t be able to save the situation. 

Sanding helps smoothen rough spots of the surface and eliminate any holes to achieve a perfect finish after painting. 

Should You Sand Between Coats of Drywall Mud?

Yes. You should sand between coats of drywall mud. However, professionals don’t recommend sanding after applying the tape but advises sanding after the second coat. 

If you decide to sand between the coats, you need to ensure that you sand in the same direction that you applied the mud on. 

Keep in mind that sanding the coats in the opposite direction won’t lead to a smooth finished surface. 

Furthermore, when you apply your last coat, you should be careful not to rub too much of the compounds. 

Is Sanding Drywall Dangerous?

No. Sanding drywall is not dangerous, provided you have the right tools. If you don’t have the best safety tools, sanding drywall can be risky to your health. 

This is because you can easily contact harmful dust components like Gypsum, Calcium, and Mica. 

If the dust components get into your respiratory system, you may have infections, irritations, or even lung cancer. 

So, it’s important to use the right tools and wear a mask when performing your drywall sanding tasks.
