Pair your power washer with the best pressure washer sandblasting kit will help you remove rust and paint, it can even help you remove those extremely difficult stains on your driveway. These kits will transform you pressure washer into a sandblasting machine, adding a whole new element to an already impressive tool.
In a hurry? I personally use the Tool Daily 5000 PSI Pressure Washer Sand blasting Kit, its not the most expensive on the list but does everything I need and can handle a massive amount of PSI, should I need a lot of force to do the job.
Wet sandblasting has become popular for many reasons, and ill show you everything you need to know to get started the right way. Ive put together a buying guide and ive also prepared some pressure washer sandblasting kit reviews of my favorite models.
The only thing you need asides this is a pressure washer, which is considerably cheaper (and in my opinion far more useful to have around the house) than the alternative option which is an air compressor. If you dont own a pressure washer already, then I highly recommend looking at either my electric pressure washer guide or if you want some serious power my gas pressure washer guide.
These sandblasters produce a lot of dust, which is incredibly dangerous to inhale. If you use a dry sandblaster, you need to make sure that nobody comes near without a mask, which is rather tricky to do if you are working from home.
Unlike the dry sandblasters, water-based sandblasting is mostly dust-free, thats not to say you shouldnt wear a respirator mask, but as the particles of sand fall down with the water droplets. Its a safe option if you want to work on a project in your own backyard. Wet sandblasting is safe and eco-friendly.
Dealing with plastic or thin metal can be tricky, as these surfaces tend to be heat sensitive. Using a dry sandblaster, these surfaces can get damaged by heat. Whether thats warping, bending, or discoloration.
Fortunately, with a wet sandblaster, as you blast the surface with the sand and water mix from your pressure washer, the water cools the surface keeping the temperature under control. When you wet sandblast, the surface will never overheat.
This sandblasting kit is made with relatively cheap materials, but dont let that put you off. This a cracking bit of equipment if you are only going to use it infrequently i.e. preparing a fence for new paint.
Attached to the rubber hose is a 10-inch sand wand, this is the part of the kit that you stick into your sand bucket. The sand wand has a perfect design so that it produces optimal sand suction without jamming.
On the other end of the rubber hose is a 16-inch pressure washer wand and attaches to any standard inch pressure washer connector. The nozzle attached to the pressure washer wand is made out of thick plastic with a replaceable ceramic tip.
For the price, this is a great pressure washer sandblasting kit, but it does have some drawbacks, while it will strip paint and rust, it can while you are using it clog up. The pipe with sucks sand out of your sand bucket can fill with water and the sand within gets stuck.
If you happen to own a Karcher pressure washer from their K Series (K2, K3, K4, K5, K6 and K7), then it is especially valuable, as this kit comes with an adapter specifically to fit this to a Karcher K Series.
This sandblasting kit includes a 10 foot-long sand hose, so you dont have to worry about a loss of suction, a plastic sand wand which like the above sandblasting kit, has been designed to suck up the sand from your sand bucket optimally. The sandblasting nozzle housing is made of a thick, sturdy plastic and hoses a replaceable ceramic nozzle.
With this kit, you get what you pay for, so dont expect to get much life out of the nozzle of the sandblaster. After a few projects and itll start to fail, at least that was my experience, though it was perfect for dealing with that single project before having to get a new kit for the next.
Why is this kit going to fail more frequently than the ones above? Well, unlike the previous kits which came with a ceramic nozzle tip, this comes with a brass nozzle tip and it just gets worn out much quicker.
The hose itself is attached to the sand wand and the spray nozzle by two clamps, this is an excellent feature as you can easily detach the hose from the sandwand and nozzle allowing you to dry the hose just in case any water comes down your sand hose.
Manufactured by Valley Industries, this sandblaster is made out of some very sturdy materials that allow it to handle up to 3500 PSI while not the highest pressure on this list, this will pair perfectly with one of these electric pressure washers.
The sand wand is made out of stainless steel and is made up of two tubes, one tube is for sand the other is for air intake, the reason this kit has two tubes is that this combination ensures an even and smooth sand flow.
Im sat here today because I forgot to put my eye protection glasses, which sit over my glasses on the other day when I was chasing out walls to run network cables. As I was using my SDS Drill to chisel out the remains after the chaser has cut to depth, small chunks of brick went flying towards my face, and well, my glasses are now sporting two large scratches. Thankfully my eyes were saved, but now Ive got to deal with scratched lenses.
So alongside your eye protection, you also get an adapter for the spray wand, this adapter can convert the standard inch quick connector of this pressure washer wand, into the bayonet fitting that fits perfectly into the Karcher K series pressure washers.
This pressure washer sand blast kit can handle up to 3200 PSI of pressurized water coming from your pressure washer and performs incredibly well as long as the water temperature remains below 140 degrees Fahrenheit.
The sand hose in this kit is made out of flexible plastic and comes in at 10 feet long, this is connected to a more robust, and studier plastic sand wand which is tapered to ensure optimal sand delivery.
Finally, theres the pressure washer wand which is made out of stainless steel, which on one end has a inch connector, on the other end theres a solid plastic nozzle with a brass gasket, the nozzle tip itself is ceramic so you dont have to worry about the tip failing on you.
This makes more than strong enough to handle all your domestic sandblasting projects. You get a very long PVC hose, this comes in at 18 foot-long. This is great, this length is in that perfect zone, ensuring that you get a steady sand flow, while that extra distance keeps your sand bucket well out of the water of water kickback, which reduces the chances of the sand clumping and blocking the feed.
Ive no doubt that there have been moments in your life when a sandblasting kit would have really saved the day, perhaps youve even spent hundreds of dollars on getting professionals in to do the sandblasting for you, thinking that its just not possible to do it yourself, well you can.
Sandblasting is exactly how it sounds, Its a powerful abrasive, you are literally blasting sand at a surface, this sand strips paint, rust, well anything that is the outermost layer is taken off of the surface.
Basically, if youve ever sanded something by hand or used a power sander such as an orbital sander, this is just a much more powerful option, thats quick and effective. No need to use sandpaper or a chemical paint stripper.
Typically to do this at home, youd need either a pneumatic tool such as an air compressor or a pressure washer. Apart from these machines, youll also need a sandblasting kit and a bag/bucket of sand or another sanding media.
So based on your circumstances and the needs of your project should dictate which one you go for, as I had a pressure washer already and I didnt own an air compressor, the decision was relatively easy.
For example, if the surface is made out of wood, then you probably want to choose dry sandblasting (I didnt..), even if the wood has been treated to handle moisture. This is because wood tends to blister or bend from exposure to excess water.
However, if you are sandblasting plastic, then wet sandblasting is your best choice because as plastics get hot, which they would from the friction of dry sandblasting, they tend to bend and change shape. However, the water from the pressure washer is a very effective way to prevent the surface from overheating.
Finally, if you are working with metal or masonry, then either method is suitable, though if you are using metal, make sure to dry the surface properly and apply an anti-rusting product if its the type of metal thats vulnerable to corrosion.
So asides from the reduced cleaning, theres also a health and safety aspect. If you are working in a populated area, I.e., near schools, office buildings or near your family home, you dont really want a dust cloud floating around.
Unfortunately with dry sandblasting thats precisely what youll get, sandblasting with an air compressor will result in a dust cloud, so make sure to wear the appropriate protective equipment, dont forget your lungs or your eyes.
With dry sandblasting, As you shoot sand onto the surface you are cleaning, every piece of sand shatters into multiple particles upon impact, as you are using air to propel them, these particles simply fly off into the air, leaving you and your project enveloped in a lot of dust.
However, when you use pressurized water to blast sand onto the surface you are cleaning, there isnt anywhere near as much dust. The water droplets catch the shattered sand particles, preventing them from wandering off. In fact, the added weight of the water helps make the particles fall to the floor immediately.
If you dont have a pressure washer or an air compressor and you are wondering which is a better choice, firstly what other jobs will you be doing? Will you need an air compressor for other tools? Or will you use a pressure washer more often?
Unless you are looking to purchase a commercial-grade pressure washer, air compressors are typically much more expensive than a water-based tool, you can use lower water pressure of around 1500 PSI for wet sandblasting, so those small, less powerful pressure washers can do the job.
This combination of water and sand quickly blasts these things away, leaving you with a clean and smoothed surface. Different materials can be used for wet water sandblasting and each one will provide a distinctive finish to the surface being cleaned.
Though there is a drawback, with this level of quality, durability, and reliability, they do cost more upfront, though youll save money and time in the long run as you wont be purchasing new tips for every sandblasting job you do and you wont spend your time replacing those tips.
Steel wears down quickly when exposed to the pressurized water and sand slurry. Unless the steel is actually stainless steel, it will also quickly corrode which will make it unsuitable for use with your pressure washer and actually increase the rate of wear.
The wand needs to be quite sturdy. So depending on your needs and your budget, you can opt for one made out of hard plastics, though personally, I would choose one made out of steel for longevity reasons.
Since you are working with a pressure washer, you need to make sure that there is adequate drainage nearby, this can be a drain, or you can work on soil or a lawn, wherever water can freely flow and get soaked up naturally.
Spread the tarp where you are going to work, and place the surface youll be sandblasting on top. As you work, the sand will fall onto the tarp. Once dried, you can run the sand through a sieve and reuse it for another round of sandblasting.
Pour your sand or other sandblasting media into a bucket or back and place it somewhere, where want wont reach it. Alternatively, you can use a bucket with a lid, Ive even seen people put an open umbrella over the sand to protect it from water.
On the other end of the metal wand is the hose and on the end of that hose will be the sand wand, this may be plastic or metal, take this and insert it into your sand bucket or bag. Or any other medium you intend to use for sandblasting.
Make sure that you get this right down to the bottom of the bucket, you want to ensure that the tip is above the sand level as it will need air, some kits have a sand wand and an air inlet to ensure an optimal mix of sand, air and water.
The powerful blasting comes with risks, bear in mind that any surface struck by this blast will suffer irreversible damage. Obviously, when we are sandblasting, we are expecting this. So make sure to be patient and controlled so nothing but the expected area is affected.
But you must keep in mind that you are operating a powerful machine. While sandblasting with a pressure washer is safe, you must respect it, its not a toy. So keep in mind all of the potential dangers.
If you are worried about safety while handling a pressure washer sandblasting kit, make sure to take the time to study the directions and use the instructions provided by your sandblasting kit manufacturer.
Water pressure is very important, but the amount youll need will depend entirely on the job at hand and the media you are using. If you have a lot of rust, well-stuck paint, or dirt you need to remove and you are using a coarse media, then you can use a pressure washer which can produce 1500 PSI or more.
A tip or rather a technique I use is to keep the sand bucket and sand wand elevated above my water wand, this way the water tends not to flow back down the sand inlet hose. If it does happen, its important to act quickly to salvage the situation; otherwise it can take a while before you can get back to it.
Its easy to wet sandblast. You take your pressure washer attach a pressure washing sandblasting kit. Take the kits probe and stick this into your sand bucket, this probe (line) is used to draw in the sand (or any other type of materials discussed in this article, being used as the abrasive substance) to the power washers extension wand, this is where the sand mixes with the water and is propelled towards the surface its being pointed at, at high speeds.
Bakingsoda which has beendesigned for soda blastingcanbe purchased from many industrialcleaningsuppliers for large projects or, for smaller projects, a small boxfrom the grocery storecan alsobe used.
This is done by attaching a kit to your pressure washer and sticking the kits prob into a bucket filled with an abrasive medium. When the pressure washer is activated, the movement of the water draws the sand up the probe line and mixes with the water.
Attach the pressure washer sandblasting kit to your power washer, follow the instructions of the power washer sandblasting kit, which will usually go something along the lines of, place the sand probe into the bucket with your abrasive medium (sand), attach the lance to your pressure washer trigger gun.
This is why using the best pressure washer sandblasting kit is the right solution for household needs. The water controls the dangerous silica dust and the price of entry is very low, while still doing a great job at removing whatever you are looking to get rid of.

I have attached a pressure water sandblasting kit to my Pressure washer. I poured in 50 lbs of pool filter sand in the bucket and inserted the probe deep into the bucket . When I turn on the Pressure washer I only get water out. I get sometimes a small dash of sand that moves a little but never gets to the nozzle, so I get no media coming out. My only thought here is my sand must be damp ? can that cause me to not get any media to the nozzle? Thank you for any help Bob Hardisty
Though It sounds as if youve put the probe in too deep? the prob needs to be inserted into the sand bucket but the top of the sand probe still needs to be above the sand as these probes need air to do their job.Get in Touch with Mechanic
