Pressure Washer Sandblasting Kit Buying Guide
A sandblaster kit is not the most complicated machinery ever. After you do your research, picking the best model shouldn’t be the toughest job either.
That said, it has critical components, like the nozzle tip, which if you don’t know about, might make you unawarely choose the wrong model.
So here are a few factors of sandblasting kits that you want to know on to pick your winner.
PSI and GPM ratings
You’ve probably come across these terms a lot of times already since you own a pressure washer.
PSI refers to pounds per square inch, which is a measurement of the pressure that your washer powers through. Depending on what type of pressure washer you own, this number can vary between a long-range.
A domestic washer can be rated anywhere between 800 to 8000 PSI. Electric and portable pressure washers seem to sit on the lower end of this spectrum whereas gas-powered ones sit at the top, which I believe is more suitable for effective sandblasting.
GPM on the other hand indicates how many gallons of water your washer pours every minute. GPM and PSI together determine the power of your pressure washer.
When you choose your sandblasting kit, you must ensure that it’s rated for minimum PSI and GPM ratings as your pressure washer is. If it’s lower than that, there’s no way you should pick that.
If it’s rated for higher ratings, that’s always a plus. I recommend you should pick a kit that’s rated for a surplus of those numbers than your pressure washer, to stay on the safe side.
Nozzle Tip Material
A little yet a crucial component that determines after you much time you’ll have to put the kit through under some maintenance.
Sandblasting is a powerful cleaning method. A mixture of water and abrasive material like sand coming at that high pressure is good enough to strip paint or rust off metal.
But all that is coming through the nozzle, which will wear out gradually as well in the process. When it does, it’ll lose its ability to concentrate the mixture and you’ll need to replace that to get the best result.
The nozzle tip you chose, is the determinator of after how long you’ll need to do that.
Nozzle tips are made of 4 materials, usually:
The best you can get. Carbide is one of the toughest materials that’s used for construction purposes of many industrial components. Since nozzle tips for sandblasting need some heavy-duty material too, they make up for the perfect match here.
Carbide is most resistant to wear and tear among all the other materials used for nozzle tip manufacturing. Corrosion resistance isn’t an issue either.
As for the general rule, you need to pay the most to get the best. Sure they cause bigger cost upfront but the service they offer, especially if you sandblast often, is unmatchable.
By far, it’s the most commonly used material for nozzle tips that you’ll find. This could be ranked as the second-best material to build nozzle tips. Ceramic might not be the hardest material out there but its selling point here is that it’s quite resistant against the sand.
That makes it a good fit for this particular scenario. Ceramic will last you quite a while and the principal reason they’re this widely used is because of the price-performance ratio it offers.
They’re a lot more affordable than carbide tips, thus you’re getting a decent performance for a quite cheaper price tag.
Steel seems to be a sturdy material in general but they might not be the perfect fit here. The reason being, steel does not hold up well in front of pressurized water and sand slurry.
On top of that, when they’ve not been made to be stainless, they tend to corrode quickly as well.
They make for great material for other parts of the sandblasting kit, but not for the tip.
Plastic would be the most undesirable material for making nozzle tips. They might fail to withstand such pressurized water and sand slurry and they’ll wear out quite fast in front of that abrasive mixture.
They might offer cheap prices but you’ll have to change it quite more often, and the hassle is just not worth it.
Metal or steel probe
As I said, steel makes for a great material to build other components of a sandblaster kit. Thus, you want your water probe to be made of stainless steel or metal.
Adjustable sand intake
It’s great if you have the freedom to adjust how much sand you want to intake. This allows you to determine how harsh you want your mixture to be depending on what type of dust or rust you want to get removed.
A sand hose is responsible for sand suction and doesn’t go through much pressure so it’ll be okay if it’s made out of good quality plastic at least. You just want to make sure it’s no longer than 20 feet since the longer it’ll be, the more effort it’ll demand of the pressure washer to such the sand.
The sandblast head is inside of which the nozzle tip sits. There’s nothing much to be picky here, you just want to ensure it lets you open it and change the nozzle tip easily.
Different nozzle sizes
It’ll be useful if your kit supports different nozzle sizes so you’ll be able to use the one that’s perfect for a given job.
Though wet sandblasting spreads a lot less dust compared to dry sandblasting, you still want to put on your safety nozzle which should be included in the package.
Best Pressure Washer Sandblasting Kit Reviews – Top 7 Picks
Jumping start the list, we have a sandblaster kit from Tool daily which is great for removing any kind of paint, graffiti, rust, baked-on grease, etc.
It’s rated for a maximum PSI of 5000 going through the heart of the rust with your powerful pressure washer isn’t going to be a problem. That said, you need a pressure washer rated for a minimum of 3 GPM and 3000 PSI for it to pull the sand properly and clean effectively.
If you’re running a tad low on those numbers you could go for the Orifice 3 version, which requires a minimum PSI of 2700 and costs the same.
You can use silica sand, baking soda, or even washed and dried river sand to clean.
Replacement nozzles are available in packs of 2 and they’re easy to replace. They’re made of ceramic and rated for 5000 psi as the stock nozzle.
It comes with ¼ quick connect so attaching and removing quickly isn’t a concern. The maximum temperature shouldn’t cross 140 degrees Fahrenheit when you’re working with it.
It tends to get clogged when you’re not using the best quality of sand. However, opening the nozzle and cleaning isn’t a job itself though.
The package includes a goggle, 10′ hose, 16” pressure washer wand (water input), 17” sand wand (sand input), and two hose clamps.
-Rated for 5000 PSI.
-Ceramic nozzle tip.
-¼ inch quick connect.
– Get clogged when the good sand isn’t used.
I had a hard time differentiating the M MINGLE’s sandblasting kit from the Tool Daily’s one. They’re pretty identical to each other except that this one’s a tad cheaper, so it deserved its place in the list of best pressure washer sandblasting kit.
The package contains a goggle, 16“ pressure washer wand for water input, 10′ hose, 17“ metal sand wand for sand input, two hose clamps. It’s great that both of the models include metal sand wands instead of plastic ones.
Also, they don’t make the sand hoses too long so pulling sand though the hose doesn’t require much pressure.
It’s rated for a maximum working pressure of 5000 psi. The minimum flow rate is 3 GPM and the manufacturer says the minimum working pressure needs to be 3000 PSI.
However, in real life, it works with lesser powered pressure washers. A 2500 PSI model even a tad less than that would do fine I guess. It’s a relief for people with lesser powered pressure washers.
You can use dry silica sand, baking soda, or washed and dried river sand. However, the sand needs to be fully dry otherwise it tends to clog up. Pool filter sand cuts fast and does not clog.
The replacement nozzles are available in a pack of two.
It has the 1/4’’ quick connect so it fits most pressure washers which have 1/4” quick connect at the end of the gun. The max working temperature is 140°F/60℃.
-Rated for 5000 PSI.
-Works with a power washer of lesser than 2500 PSI.
-Easily replaceable ceramic nozzle tip.
-¼ inch quick connect.
-Clogs up if the sand is not fully dry.
We have another sandblasting kit here coming from M MINGLE, and this one’s made for less powerful pressure washers. It’s rated for maximum 2500 PSI whereas the previous two models would require minimum that pressure to function properly.
The maximum flow rate is 2 GPM which further clears its position.
The package includes all other components as before and has an additional Karcher Adapter with it.
This Kit is made to suit the Karcher Pressure Washers like the K2, K3, K4, K5, K6, K7, and other models. It has the standard ¼ quick connect so suits most other pressure washers and for the Karcher ones, it includes the adapter for compatibility.
Many Karcher pressure washer owners seem to pick this tool for that reason since those are not compatible with most other sandblasting kits which all have ¼ connectors.
However, this sand wand is made of plastic which is not the most durable one.
You can use all kinds of standard dry sand meant for abrasive cleaning and baking soda as well.
-Suitable for lower-powered pressure washers.
-Includes adapter for Karcher Pressure Washers.
-Ceramic nozzle tips.
-Plastic made sand wand.
Tool daily has made its appearance back in the list, and with an identical model as the M MINGLE’s one this time.
The reason it’s staying below the M MINGLE’s 2500 PSI kit is that this particular model doesn’t seem to love Karcher pressure washers that much, which is a big name for pressure washers.
You guessed it right, the adapter is missing here. The package includes all other things like google, 10′ hose, 10″ plastic sand wand, 16″ water wand, clumps and all, except the adapter.
Now, Karcher has quite a few models around this PSI range so adapting to them would be a great help. Seems like you have to help yourself and buy an adaptor separately which costs a little, by the way.
So it has the standard ¼ inch quick-connect so it’ll connect with most pressure washers which have 1/4’’ quick connect at the end of the gun. The maximum working temperature should not cross 140 degrees Fahrenheit which you need to ensure.
It too has ceramic nozzles and a replacement pack is available which is quite cheap. You can use silica sand, dried river sand, baking soda to clean with it.
However, you want to make sure the sand probe stays upright, and don’t let it get wet, which is true for all other models as well.
-Suitable for lower-powered pressure washers.
-Ceramic nozzle tips.
-Plastic made sand wand.
-Do not include an adapter.
Sandblasting is usually done best with gas-powered pressure washers, because of the great power they offer. But what if you want to do it with an electric pressure washer?
You could do that with this Electric Pressure Washer Sandblasting Kit from Karcher. But the ability to sandblast with your electric pressure washer comes at quite a cost, though.
It has a price tag way higher than the kits we talked about so far.
Unlike the other kits, this comes assembled and in one piece, along with a goggle. The water and sand wands are made of plastic but they’re durable.
The sand hose is made to be a little shorter so that it can pull the sand with lesser power. It’s compatible with all of Karcher’s consumer electric pressure washers and most other electric pressure washers from renowned brands.
However, it’s not made for gas-powered pressure washers.
About the performance, it gets the job done, but takes more time than powerful gas-powered pressure washers which is completely understandable. It has made sandblasting possible with electric models and that’s what many users love it for.
When you have little to medium abrasive cleaning jobs, you may consider buying it. But if you have a lot of rust and dirt to get away with sandblasting, it might not be the perfect fit.
For an electric pressure washer sandblasting tool, it does its job and that’s what we can take away from this tool.
-Lets you sandblast with electric washers.
-Cleans small surfaces quite well.
-Fits most consumer electric washers.
-Takes time to clean.
Made for heavy-duty jobs, the RIDGE WASHER pressure washer sandblaster attachment loves power. The more powerful sandblasting pressure washer you equip it with, the better it cleans.
It can withstand up to 5000 PSI and at that pressure, it cleans like crazy fast. The minimum pressure as the manufacturer claims is 3000 to 3500 PSI with a minimum flow rate of 4 Gallon Per Minute.
Those numbers are to ensure that it performs up to its standards, but you can get away with smaller metrics as well. It’s just you’ll have to give up something on the standard performance the RIDGE WASHER kit promises.
It comes with really tough ceramic nozzles that hold up to the aggressiveness of this kit. Talking of replacement, not only are they replaceable but you get 2 extra replacement nozzles in the package also, which is a nice touch.
Tension-free sandblasting without having to find and order good quality nozzles for a long time.
The build quality of this kit is one of the best among the models we talked about so far, if not the best. Both the wands are made of high-quality steel and the probe is made of Pure brass which no other kit had. All of them were made out of hard plastic.
You can use any type of sand that we use as abrasive material but make sure it’s dry. It consumes a lot of sand, though.
It has a standard ¼ inch quick connector so it’ll fit most pressure washers having that end.
-Heavy-duty sandblaster pressure washer.
-Comes with 2 extra nozzles included.
-Great build quality.
-Consumes a lot of sand.
Summing up the list of best pressure washer sandblasting kit, we have got a model coming from a company named AgiiMan. It stands in a sweet point for PSI ratings.
It’s rated for a maximum of 3200 PSI. So working with lower PSI rated pressure washers isn’t a problem. Again, bringing the game up to match some mid-tier powerful consumer pressure washer is its jam too.
Few other lower PSI rated kits we talked about had 2500 PSI max, so rocking them with a pretty powerful pressure washer wasn’t possible, which is not the case for this kit.
All the other things are quite standard. In the package, it contains everything that you expect a sandblaster kit to have. The wands are made of steel and plastic and they’re sturdy.
And this is another model that comes in with an adapter to suit Karcher’s and other brands’ pressure washers that don’t support ¼ quick connect. And those that support it, you can simply connect it to them without the adapter.
It comes with a durable ceramic nozzle that’s capable of withstanding quite some abuse. However, it’s underwhelming that you can’t replace the nozzle tip.
-Rated for 3200 PSI.
-Includes an adapter.
-Gets rid of rust fast.
-Nozzle tip is not replaceable.
Dry vs Wet Sandblasting
Dry sandblasting or wet sandblasting with a pressure washer? Which is the best sandblasting method?
This is a never-ending argument and let’s settle it once and for all, today!
The answer in one sentence is, both can be the best, depending on which circumstances favor which method the most.
Let’s give you an overview.
The most important factor to consider while choosing your sandblasting method is what surface you’re working on.
Working on wood? Dry sandblasting is the best choice. Water will harm the wood in the short or long term, even if it’s treated. Excessive water pressure could also cause blisters on it.
Again, say you’re working on a plastic surface. Wet sandblasting is your best bet here. Hot air coming out of the air hose along the friction of sand particles on the plastic surface generates a great amount of heat, and that could cause the plastic surface to change its shape to some extent. Water will keep it cool instead in the case of wet sandblasting.
Working with metal? Both are great methods here.
I prefer wet sandblasting considering how the two methods deal with dust.
Let’s talk dry sandblasting. When the sand hits the surface at great speed, every piece of it shatters into several particles on the impact. And then there’s high-flow air that eases their journey around.
So very soon you’re within a cloud of dust that’s not at all good for your lungs and other body parts. Also, the things nearby will get highly dirty which will take effort to clean later on.
To save yourself as much possible from that cloud of dust, you need respiratory masks, eye protection paramount, and other costly equipment. So when there are things nearby, you should try as hard as you can to avoid dry sandblasting.
On the other hand, in the case of wet sandblasting, the sand elements face a lower impact force while hitting the surface as they’re mixed with water. So they get shattered in fewer particles. And the water is also there to prevent them from wandering off.
The water contains whatever particles are there and make them fall right down away. So there’s no flying cloud of dust that covers everything. Rather, there is concentrated wet sand garbage that’s much easier to clean off.
So wet sandblasting seems more environmentally friendly. There’s clean air to breathe.
We want to get our home chore tasks done as cheaply as possible. Say you don’t have any air compressor or pressure washer as of now and you need to buy one of them for sandblasting, so which will be the most affordable purchase?
Usually, air compressors or total air-based working toolsets cost quite higher than water-based tools. On top of that, you can use pressure washers for many other jobs around the house than you can use your air compressor for.
And you don’t need to buy the most powerful pressure washer either, a decent 2000 PSI unit will do fine. So pressure washer seems to be the value for money buy here.
As I said earlier, there’s no universal best, rather it depends on the type of job. However, if you disregard what surface you’re working on for a while, wet sandblasting seems to be the winner because of how they deal with dust and how more affordable they are compared to air tools.
Advantages of power washer sandblasting Kits
Affordable but Powerful
Many people seem to sit on the thought that sandblasting is expensive. Is it?
There are high chances that they’re only considering or aware of dry sandblasting, which can get a little expensive. I mean, if you have to buy a whole air compressor and other attachments only for sandblasting and a few odd jobs out here and there, it doesn’t seem economical.
But what about wet sandblasting?
Most of us require a pressure washer around our house and we probably already have one. If you don’t have one, head over to this gas pressure washer buying guide, cause it’s a great household machine to have.
Let’s assume that you already have one of these. After that, how much does it cost to turn that into a sandblaster?
25 bucks. Most of the kits I recommended in this piece costs around that. Isn’t that really affordable?
At the same time, a powerful pressure washer sandblaster can wash away rust real quick. So they’re highly effective at the same time.
Easily tackle nooks and crannies
Have you ever manually sanded a large surface with sandpaper? It’s already tiresome to sand flat areas, but things get a little more interesting when you reach nooks and crannies? How frustrated is it to sand an area that has a heavy layer of rust and your hands don’t even reach properly there?
Even if you use a power sander, you can’t reach nooks and crannies. Power washer sandblasters come to the rescue here. Water and sand mixture can reach anywhere and punish rust that is hiding in even the deepest corner.
Remove caked-on layers
How interesting it was to hand-sand a large area with sandpaper last time? All I remember is, after an hour, I wasn’t done even with a decent part of the total area and already had a sore hand that felt like coming out.
Tried power sander, but that vibration, ugh!
None of that pain will be felt while you use a sandblaster, and the baked-on grease or coat of paint will be removed within a few minutes as well.
Running a sandblaster takes almost no effort to clean a surface compared to how much effort it would’ve needed if I had to clean it with sandpapers or power sanders.
As you already know, wet sandblasting deals with dust amazingly. Dry sandblasting would create a cloud of dust that’s full of unhealthy particles for the body. You must put on respiratory masks and tight goggles for protection and you’d be covered with dust after you’re done.
The surrounding would get dirty as heck as well and it’s a task itself to clean the surrounding after you’re done with sandblasting.
Whereas wet sandblasting is almost flying dust-free so you don’t need to put on equipment like a respiratory mask, just a pair of goggles will do. And no dust means you won’t get dirty nor will your surroundings.
It’ll create a layer of wet sand on the floor or ground which is not so tough to get rid of.
The surface stays cool
Since wet sandblasting is done with a mixture of water and sand, the surface stays cool because of the waters’ cooling properties. This is crucial when you’re working on a surface that’s delicate to heat, like plastic.
As a response to overheating, they could change their shape, which is a concern when you dry sandblast. Wet sandblasting is free from such issues.
Sandblasting Kit Set Up Guideline
Setting up your sandblasting kit is quite straightforward. You need to choose a good location, ready your surface, attach the kit to the pressure washer, and fire up the washer to start blasting.
You should try to choose a large and open space. You want to ensure water drainage nearby, or you could choose a grass field where the water will be naturally soaked up.
Things You Need
- A pressure washer.
- The Sandblasting kit,
- Abrasive Media – silica sand, baking soda, dried river sand, etc.
- Protective equipment
- A large tarp if you want to collect sand and reuse.
I’ll assume you’ve chosen a nice and open place to sandblast. I believe that place has a proper water drainage system and access to electricity if you’re working with an electric pressure washer.
If you want to reuse your sand, I’ll assume you have your tarp loaded. Spread the tarp on the ground and put your object on it. You want to choose a tarp that’s quite larger than the object you want to sandblast.
After you’re done sandblasting, you’ll need to let the water vapor and completely dry up those sand. You want to clean them afterwards to ensure there’s no rust particle, paint particle is staying hidden in there.
Setting up the Sandblasting Kit System
Connect the metal water wand of the sandblasting kit to the pressure washer wand or gun. If both the ends support ¼” quick-connect, it should fit right in.
If the pressure washer gun doesn’t support so, you’d need the adaptor that we talked about earlier. It’s great if that comes included in your kit, or you’d have to buy that separately.
In such a case, connect the adaptor with the spray gun and now the sandblasting kit’s water wand should fit right in.
Now you’re left with the sand wand that’s connected to the plastic hose.
Take your bag of abrasive media, pour it into a bucket. Take the sand wand, and put it into the sand or other media in a way the bottom of the wand stays sunken in the sand but the top of it stays exposed for air intake.
Cover the sand carrying bucket well so no droplet of water could make its way into that. This is crucial to ensure your kit doesn’t get clogged up. No kit does well with wet sand so find out a way to keep your sand completely dry.
Another crucial factor here is that you need to keep the sand probe above the water wand all the time, so gravity won’t pull any water to the sand hose which is meant only to supply dry sand to the system, not to intake any portion of running the water.
There’ll be quite some sand and water kickback, so protective equipment is crucial even if you’re not dry sandblasting.
Here are the essentials:
Goggles: Put on a pair of goggles to protect your eye from hurting sand kickbacks. You could also use a protective facemask but that seems overkill for me.
Waterproof clothing: Since you’re dealing with water here, you want to put on your waterproof clothes and boots that won’t slip. If you want to pass on that, you’ll have to clean your general clothing every time.
Here are the optionals (But useful):
Breathing mask: Wet sandblasting dramatically reduces the amount of sand dust, but there’ll be still some flying around. It’ll not hurt if you put on your breathing mask to add a layer of protection to your lungs, especially if you’re suffering from breathing problems already, like asthma.
Hearing protection: Pressure washers are not really silent and if you feel your ear might hurt from prolonged noise, why not put on a pair of earplugs or earmuffs?
You’re all set to get rid of those stubborn rust or old paint. Keep in mind that getting rid of stubborn stuff with sandblasting might require a while so be patient and focused.
Another little thing to keep in mind, that you should always keep your wand towards the ground when you’re powering up the washer. Then gradually aim into the cleaning surface.
And maintain a little distance from the surface, don’t get too close.
FAQ About Sandblasting Kits
How much pressure do you need to sandblast?/ How much psi do you need for sandblasting?
Typically, more than 2000 psi is recommended to sandblast effectively. The more pressure you put, the faster and more effectively you clean. You could sandblast with lower-powered washers as well, but that’ll take more time and the cleaning won’t be so deep and thorough.
How do you wet sandblast?
Find the best pressure washer sandblasting kit for yourself. Hook it with your awesome pressure washer, and start wet sandblasting.
Can you use an air compressor as a power washer?
Yes, you can. But that won’t be regarded as wet sandblasting anymore. That’s dry sandblasting which we’ve talked about in brief.
What type of sand should I use for sandblasting?
Silica sand is preferred. But you could use properly washed and dried river sand or even baking soda as well.
Can you sandblast with a pressure washer?
Absolutely you can. And this article tells you exactly how you do that.
Best Pressure Washer Sandblasting Kit – Wrap up
One pressure washer can do many things and sandblasting is one of the best among them. When done properly with the appropriate sandblasting kit, it could dramatically reduce your effort needed to clean through stubborn stuff.
