Combining your power washer with the best pressure washer sandblasting kit can help you remove paint and rust, or even help you with extra hard stains on your driveway. These kits are designed to transform your pressure washer into sandblasting machines, thus widening the utility of power washers even further. Not only will you be able to vapor blast at home, but you also get to do it in a clean and quick way.
Wet sandblasting is popular for many reasons, and we’ll tell you everything you need to know to get started. Apart from our buying guide, we also prepared pressure washer sandblasting kit reviews of our favorite models. Let’s get right to it!
Benefits of Pressure Washer Sandblasters
If you’re still not sure if pressure washer sandblasting is the right way to go, here are a couple of benefits that may help you make your decision.
1. Remove Caked-on Layers
You don’t need big muscles and a bunch of elbow grease to sand down a bit of rust. With a pressure washer sandblasting kit, it’s easy to tackle even caked-on dirt, rust, paint, grease, stains, and so forth. You can even remove that old chewing gum from the concrete in front of your home. The best part is – it’s very easy to do, it’s not taxing on your back or shoulders, and it takes very little time to set up and do everything.
2. Affordable But Powerful
Pressure washer sandblasting kits are very affordable – after all, it’s simply a bit of metal and a plastic hose. Sandblasting media is very easy to get, too, and you can get big bags of sand for a few bucks at your local store. The only thing you need is a pressure washer, which is also considerably cheaper (and far more useful around the house) than the alternative – an air compressor. If you don’t own a pressure washer already, you can find an ideal model for you on our homepage.
3. No Dust
There’s a reason why you need a respiratory mask whenever you use a traditional, dry sandblaster. They simply create a lot of dust, which is very dangerous to inhale. If you use a dry sandblaster, it’s extremely important that nobody comes near without a mask, and this is very hard to do if you’re working from home.
Unlike dry sandblasting, water-based sandblasting is mostly dust-free, since the particles of sand fall down together with water droplets. If you want to work on your project in your backyard, wet sandblasting is the way to go – it’s safe and eco-friendly.
4. Easily Tackle Nooks and Crannies
Odd shapes and surfaces can be a sure way to get frustrated if you’re working with sandpaper. Getting into those crevices is nearly impossible, or very uncomfortable at least.
With a power washer sandblasting kit, dealing with nooks and crannies is a breeze. All you need to do is to point at them!
5. The Surface Stays Cool
If you’re working with a heat-sensitive surface, such as a piece of plastic or thin metal, you don’t want your panel to get damaged by heat. Whether it’s warping, bending, or discoloration, heat can have irreversible adverse effects on some materials.
As you blast your surface with sand and water from a pressure washer, the cool water keeps the temperature under control. When you wet sandblast, your surface will never overheat.

Best Pressure Washer Sandblasting Kit Reviews
1. Tool Daily 5000 PSI Pressure Washer Sandblasting Kit
Next up, we have a higher-rated, and yet relatively affordable model made by Tool Daily. This sandblaster is rated for higher pressure, and it can handle up to 5000 PSI. This makes it perfect for many projects that you wouldn’t normally be able to complete at home, including removing old paint from your car and scrapping off caked-on, old layers of rust. Despite being able to do these, more demanding projects, this product still comes at a rather low price point. This sandblaster comes with a 17-inch sand wand, which is made out of stainless steel, and it can handle the higher sand flow that higher pressures require. The hose is 10 feet long, and it’s made out of high-quality material. The hose is secured on two points with clamps, which is great since you can easily detach it and dry it if any water comes down your sand hose. The nozzle is made out of brass, and it comes with replaceable ceramic tips. You can connect the steel pressure washer wand to any standard 1/4 inch quick connector. If you’re looking for a long-lasting sandblasting solution, this model is a good choice.
- The detachable sand hose is easy to dry in case of accidental water leak
- Handles up to 5000 PSI
- You must make sure you secured your hose tightly
2. M MINGLE Pressure Washer Sandblaster Kit
M Mingle makes our next pick, which is a mid-range product that can help you complete most sandblasting projects you may have at home. This unit is especially valuable to anyone who owns a Karcher pressure washer from their K series (K2, K3, K4, K5, K6, and K7) since it comes with an adapter. This adapter fits right into Karcher K washers, and allow you to use any standard 1/4 inch connector with it, including the sandblaster. That being said, it also fits any standard 1/4 inch connector pressure washer. The sandblaster itself is of medium quality, appropriate for the price. It has a 10 feet long sand hose, which will maintain even suction without being too short. The sand wand is plastic, and so is the nozzle. Inside the nozzle is a replaceable, ceramic tip. The pressure washer wand is 16 inches long and made out of sturdy metal. The sandblaster is suitable for pressures up to 2500 PSI, and temperatures lower than 140 degrees Fahrenheit. In the kit, you get the sandblaster, Karcher adapter, and a pair of protective eyewear.

3. DUSICHIN DUS-017 Wet Sanding Pressure Washer Sand Blasting Kit
If you’re looking for an affordable option, Dusichin has got you covered. However, you should know that you get what you pay for – the tip of this sandblaster won’t last long enough to help you cover several projects. That’s mainly because it comes with a brass nozzle tip, which can get worn out quickly, and it’s not as sturdy as regular ceramic tips. Because of that, we recommend using this sandblaster with finer media like baking soda, if you have a light layer of rust or dirt to remove. You can connect this sandblaster to any standard 1/4 inch quick connector, and you can use it with your pressure washer set up anywhere between 1000 and 2600 PSI. The sand wand is made out of tapered plastic, which ensures even feed and prevents jamming. The sand wand is 7.2 inches long, while the pressure washer connector wand is 17 inches long.
- Very affordable
- 17-inch long pressure washer wand
- The brass nozzle tip isn’t very durable
4. Tool Daily 2500 PSI Pressure Washer Sandblasting Kit
If you’re looking for a sandblaster that can handle most domestic work, but that doesn’t cost an arm and a leg, look no further than Tool Daily. This model is ideal if you own a lower-rated pressure washer since it’s made to work with pressures of at most 2500 PSI. This sandblasting kit is made out of somewhat cheap materials, but it’s a good tool to have around if you don’t plan on sandblasting frequently. It comes with a 10 feet long rubber hose, which is long enough to reach your sand bucket, but not too long as to lose suction power. The 10-inch sand wand is made out of sturdy plastics, and it has a tip that is design perfect for optimal sand suction without jamming. When it comes to the pressure washer wand, it’s 16 inches long and fits any standard 1/4 inch pressure washer connector. The nozzle is made of thick plastic with a replaceable ceramic tip. You also get a pair of protective eyeglasses with this sandblaster, so it’s a rather good deal for the price.
- Ceramic nozzle tip
- 10-inch long sand hose
- Plastic sand wand
5. Valley Industries SBK-400 Wet Sandblast Kit
Our next pick is a somewhat pricier, but also higher-quality sandblaster which can last you for a long time. Made by Valley Industries, this sandblaster is made out of sturdy materials that are able to handle pressure up to 3500 PSI, and up to 10 gallons of water per minute from your pressure washer. The 18 feet long sand suction hose is made out of rubber and reinforced with a metal mesh, so it will last a long time and handle many projects. The same goes for its sand wand, which is made out of stainless steel and comes with two tubes – one for sand, and one for air intake, as this combination ensures even and smooth sand flow. The nozzle is made out of brass, and it comes with a carbide tip – which is the most durable and highest-quality type of tip out there. The pressure washer connector wand is very short, but it fits most standard pressure washers with its 1/4 inch male plug. Overall, despite the steeper price, this sandblaster is a worthy investment because it’s made out of high-quality, durable, and sturdy materials.
- Carbide nozzle tip is the most durable kind out there
- Mesh reinforced 18-feet long sand hose
- Short pressure washer wand
6. AgiiMan Pressure Washer Sandblasting Kit

This model is made to handle water pressure of up to 3500 PSI, with the flow of at most 10 gallons of water per minute. This makes it strong enough for most domestic sandblasting projects. It comes with a very long PVC hose, which is 18 feet long – long enough to have your sand bucket far away and protected from water kickback, but short enough to keep a steady sand flow. The hose ends with a steel sand wand, which has two pipes, one for sand output, and one that ensures proper airflow. The pressure washer wand isn’t extended, so you don’t lose any pressure with it. It fits any standard 1/4 inch quick connector.
- Sturdy materials – brass nozzle and steel sand wand
- 18 feet long sand hose
- Somewhat expensive
What Is Sandblasting?
Chances are, you’ve encountered quite a few moments in life when a sandblasting kit would really save the day. Perhaps you even had to spend hundreds of dollars on a simple sandblasting job you could’ve done on your own. Well, now you can.
Sandblasting is as powerful as it sounds – it’s literally about blasting sand at a surface. As the sand hits the object, it strips the paint, or whatever the outermost layer is, right off the surface. Because of this, sandblasting is a popular procedure that is used in many industries. However, it’s by far most frequently used to strip off paint and rust off any vehicle, including cars, boats, motorcycles, and even airplanes.
You can remove anything, from rust, paint, baked-on grease, to graffiti. Sandblasting is a very effective and quick alternative to sanding with sandpaper, or using chemical paint strippers.
To do this at home, you will need either a pneumatic tool such as an air compressor, or a pressure washer. Apart from the big machine, you will also need a sandblasting kit, and a bag of sand or other sanding media. In general, domestic use sandblasting kits use silica sand, purified river sand, builder’s sand, pool filter sand, or even more delicate media like baking soda or crushed walnut shells.
With a pressure washer, you’re using the power of pressurized water to blast sand onto your surface. The combination of sand with water results in a cleaner job with less dust, and great results overall.
Dry vs Wet Sandblasting
You might be wondering whether an air compressor or a power washer is a better choice for the job at hand. The truth is – there’s no universal answer, and both methods are very good at what they do. The choice truly depends on the particular project, and your circumstances. Here, we will try to give you an overview of the basic differences between the two methods.
The most important factor you should consider is the surface you’re working with.
If your object is made out of wood, for example, you should choose dry sandblasting, even if your wood is treated to handle moisture. That’s because wood tends to bend or get blisters from exposure to excess water.
On the other hand, if you’re working with a piece of plastic, you should definitely opt for wet sandblasting. Plastics bend and change shape if they get too warm, and the water from the pressure washer is an effective way to prevent surface overheating.
Finally, if you’re working with metal or masonry, you can use both methods since they’re equally good. However, you may want to treat your metal surface with an anti-rusting product, if it’s a type of metal that’s vulnerable to corrosion.
The issue of dust is the reason why many professionals opt for wet sandblasting whenever they can. If you need to work in a populated area, especially near schools, office buildings, or near your family home, you don’t want to have a cloud of dust flying all around.
That’s exactly what happens when you sandblast with an air compressor. As you shoot sand onto your surface, every piece of sand shatters into several particles on impact. When you use air to blast sand, these particles simply fly off, leaving your project enveloped in a lot of dust. That’s why you need more safety equipment when dry sandblasting – the dust makes a respiratory mask and eye protection paramount.
On the other hand, when you use pressurized water to blast sand onto your surface, there isn’t as much dust. The water droplets don’t allow the shattered sand particles to wander off, and water contains the sand, making it fall down right away. That’s what makes wet sandblasting more environmentally friendly and better for the people around you as well – no dust means safe, clean breathing air. Because of that, you don’t have to wear a mask over your nose and mouth when working with a pressure washer sandblasting kit.
When it comes to home use, it’s just natural if you want to spend as little money as possible. If you don’t have either a pressure washer or an air compressor, and you’re wondering which one is a better choice, affordability is an important factor to consider.
Unless you’re looking for the best commercial pressure washer, air compressors are typically way more expensive than a water-based tool. You can even use lower water PSI of around 1500 for wet sandblasting, so even smaller, less powerful pressure washers can do the job.
Pressure Washer Sandblasting Kit Buying Guide
Finding a good pressure washer kit isn’t complicated. However, there are a couple of things you should be aware of, in order to make a good choice. After all, you need the sandblasting kit to do a good job on the project you’re working on, and it should be compatible with your pressure washer. Here are the most important factors you should consider before you make your pick.
1. PSI and GPM ratings
You’ve probably heard of the PSI and GPM ratings when referring to your pressure washer.
PSI stands for pounds per square inch, and this measurement tells you how much pressure your washer can create. In domestic use models, PSI ranges anywhere between 800 and 10 000, with portable pressure washers usually ranging between 800 and 2000, and gas-powered models being more powerful and maxing out at around 8000 PSI. GPM tells you how much water your washer pours out, and it stands for gallons per minute. Together, these two numbers give you the actual power of your power washer.
When you work with a sandblasting extension on your pressure washer, you need the two components to match. A low-rating sandblasting kit will simply not be able to withstand the pressurized water coming from your power washer. The most common failing spots for this kind of a contraption are the nozzle, where sand and water combine, and the water wand, which must be strong enough to support the pressurized water flow.
2. Nozzle Tip Material
Sandblasting has the power to strip paint or rust off metal, even when you’re several feet away from the surface. Considering the force with which the mixture of sand and water comes out of the nozzle tip, it’s easy to guess that the nozzle tip needs to be very strong to withstand that pressure and abrasive power. Over time, the tip of your sandblaster kit will surely be worn out beyond repair, but the type of nozzle tip you choose will change how much you can sandblast before you need a replacement.
Carbide, the collective name for compounds of carbon and metal, are some of the toughest materials used for many industrial tools and equipment.
Accordingly, carbide nozzle tips for sandblasting kits are by far the most resistant to wear and tear. Additionally, carbide materials are resistant to corrosion, which is very valuable for those who use their pressure washers to sandblast.
Of course, that also means that they cost the most upfront, but in the end, they are worth the investment because they save you the trouble of having to get a new tip for every sandblasting job you need to do.
Ceramic nozzle tips are by far the most commonly used for sandblasting. That’s because they have a great ratio of durability and price.
Made out of natural materials, ceramic tips may not seem intuitively strong. However, the material is very resistant to sand abrasion.
While they’re still considerably shorter-lasting compared to carbide tips, the advantage of ceramic tips is that they’re very affordable. You can get them for only a couple of dollars per piece.
Even though you may think that a steel tip would have better performance compared to ceramic ones, that isn’t actually true. Steel wears off quickly when exposed to pressurized water and sand slurry. Additionally, unless it’s made to be stainless, steel corrodes quickly, making it unsuitable for use with a pressure washer. However, steel is a great material for other parts of sandblasting kits, especially the sand intake wand.
3. Sand Intake
The sand intake of a sandblasting kit is composed of two parts: the hose and the wand.
The hose transports sand from your sandbag to the nozzle tip, where it’s mixed with water and sprayed.
Even though it transports sand, the hose doesn’t generally suffer a lot of abrasive damage, and it’s usually one of the longer-lasting parts of a sandblasting kit. That’s why most sandblasting sand hoses are made out of plastic or rubber, with rare ones being made out of metal.
However, you want to ensure your pressure washer sandblasting kit works flawlessly even if you only have a weaker electric pressure washer which doesn’t put out a lot of PSI. To make sure that the sand intake is sufficient, you should stay away from super long hoses that are more than 20 feet long.
The wand of the sand intake construction is on one end of the hose. That’s the part that you should put inside your container with sand, and it serves to suck in the sand and bring it into the hose. The wand needs to be quite sturdy. Depending on your needs and budget, you can opt for a stainless steel wand or one made out of hard plastics.
How to Set Up Your Sandblasting Kit
Setting up your sandblasting kit is not difficult. You can start sandblasting as soon as you set up your surface, sand, and pressure washer.
We recommend working in a large, open space.
You should make sure that your area has a water drain nearby since you don’t want the water to linger. Otherwise, try to sandblast on a grass field, so that the land can soak up water. If you’re using silica sand, you don’t need to worry about the environment, since there are no chemical substances like soap involved – it’s just clean water and natural sand.
1. What You Need
- A bag of abrasive media – silica sand, crushed walnut shells or corn cobs, baking soda, or similar
- A pressure washer – ideally over 2000 PSI
- Your sandblasting kit
- A large tarp or similar water-resistant material to collect sand
- Protective equipment – Protective eyeglasses and clothes, a respiratory mask
2. Setting Up
Before you can start stripping that layer of rust off, you need to create a proper set-up for the work. Follow these steps and you’ll have no issue while you work.
2.1. The surface
First off, you should create the right setup for sandblasting your surface, whether that’s a car, a panel, or an old wheelbarrow.
Since you’re working with a pressure washer, you need a water drain nearby. Alternatively, you can work on soil or a lawn, where the water can freely flow and get soaked up naturally.
Of course, you need access to electricity (unless you have a gas-powered pressure washer) and water for your power washer to run.
If you want to save and reuse sand, you need a large tarp. Spread the tarp where you want it, and place your surface on top of it. As you work, sand will fall onto the tarp. Later on, you can leave the sand to dry, run it through a sieve, and use it for another round of sandblasting. However, you should pay attention to clean the sand thoroughly, since you don’t want tough pieces of rust, paint, or plastic to ruin your next project. Always wait for the sand to dry completely before using it.
2.2. Assembling the kit
Now, you need to assemble and prepare your equipment.
First off, you should get your pressure washer up and running as you usually do.
Take the metal wand of your sandblaster kit, and connect it to your pressure washer wand. It should fit right in.
The other part of your sandblaster is a plastic or metal tube at the end of the hose. This tube (which looks like a probe) goes into the sand or another media you’ll use for sandblasting.
Pour your sand into a bucket, and place it somewhere where water won’t reach it. Alternatively, you can use a bucket with a lid, or even put an open umbrella into the sand to protect it from water.
- It’s paramount that your sand is completely dry while you work – otherwise, it will jam the hose.
Now, you can put your sand wand into the bucket. Immerse it into the sand and get it to the bottom of the bucket – but leave the tip of the want out, so it can get air. Some people don’t use a bucket, and simply immerse the sandblaster wand into the bag of sand. This method can work, but remember that you must leave the top of the wand exposed for air intake.
- When holding your sandblasting kit, make sure that the washer wand is positioned under the sand wand at all times. That way, you prevent water from getting into your sand hose, potentially jamming it.
Step a couple of feet away from your surface. You’re ready to start!
3. Safety during Handling
Sandblasting is not an easy job. It requires patience and good control, and the powerful blasting does come with risks. In order to stay safe while working, there are a couple of rules you need to follow.
3.1. How to start blasting
- Whenever you’re just starting your pressure washer, you should make sure to hold your wand pointing down.
- Step a couple of feet away from your surface when you start blasting. You can slowly get closer, but keep on checking your surface, because the high-pressure spay may damage it if you get too close.
3.2. Protective equipment
Protective equipment is absolutely essential when you’re sandblasting. There’s a lot of sand and water kickback, which should not get into your nose. Furthermore, you don’t want to get soaked or damage your hearing while working. To stay safe, you need:
- Goggles, or protective face mask – there’s a lot of sand kickback in sandblasting. You don’t want sand in your eyes.
- Breathing mask – Even though wet sandblasting dramatically reduces the amount of sand dust, it’s still important to protect your lungs. Remember that silicosis is a serious disease that affects your breathing.
- Waterproof clothing – Since you’re working with water, you should wear waterproof clothes and boots that won’t slip.
- Hearing protection – You already know that your pressure washer is very loud. Prevent excessive hearing loss by wearing earplugs or earmuffs when working with such powerful machines.
FAQ About Sandblasting Kits
1. Are pressure washer sandblasting kits safe to use?
Yes – for as long as you keep in mind that you’re operating a powerful machine. While sandblasting with a pressure washer is safe, it’s not a toy, so you should always be mindful of the possible dangers. If you’re worried about safety while handling your pressure washer sandblasting kit, make sure you read and follow our directions and the use instructions provided by your sandblasting kit manufacturer.
2. What kind of sand should I use for sandblasting?
Choosing the right type of sandblasting media is important – and it really depends on the job you’re doing.
If you’re not sure whether you should use a finer or coarser media, you should test whether the finer one works well, and only go with the coarser one if it doesn’t. That’s because chunks of coarse media may damage some surfaces when blasted at high pressures. The examples of finer media are baking soda and crushed walnut shells, while coarser media includes crushed glass and swimming pool filter sand.
3. How much pressure do you need to sandblast?
Of course, the water pressure you need for sandblasting depends on many factors – most importantly, the severity of the rust, paint, or dirt you need to remove, and the type of media you’re using. However, you should make sure your pressure washer can output more than 1500 PSI. Start with lower pressure and adjust as you go for the best results.
4. What do I do if water gets into the sand supply hose?
You should always hold your sandblaster so that the sand hose stands above the water wand – this way, no water will come down the sand hose. However, if that does happen, it’s important to salvage the situation before you continue.
Turn off your pressure washer, and disassemble the sandblaster. Remove the sand wand from the sand, since you don’t want it to get wet. If your model comes with a gun trigger, hold it open. If you can, remove the hose from the rest of the construction. Let it air dry. Continue working once the hose is dry.
Sandblasting is the ideal solution for many things – from restoring a rusty, old wheelbarrow, to stripping paint off your car for a repaint. But traditional, air-based sandblasting comes for a steep price, and with a lot of risks for your lungs. That’s why using the best pressure washer sandblasting kit is the right solution for domestic use: the dangerous silica dust is controlled, the price is quite low, and it truly does a great job at removing whatever you need to get rid of!
