Gravity-Fed Delivery System
Gravity-Fed Delivery System
Turn Your Pressure Washer Into a Professional Wet Sandblasting System
Your pressure washer has the power. This is what makes it feed right. Suction-fed systems sputter, clog, and stop mid-job. This one doesn't. Gravity drops the media, the sleeve valve meters it, and precision air assist keeps it moving consistent flow, no dry patches, no stopping to shake a bucket. Engineered in the USA.
Blast Longer with the PVC Gravity-Fed Delivery System
If you're tired of stopping mid-job to shake your bucket, unclog your pickup hose, or fight inconsistent abrasive flow, it’s time to upgrade. The SandBlastKit Pro™ PVC Gravity-Fed Delivery System is designed for smoother media feed, fewer interruptions, and more consistent wet sandblasting performance.
Built with a gravity-fed PVC media bag, patent-pending metering sleeve valve, and precision air assist, this pressure washer sandblasting upgrade feeds abrasive media downward naturally — like an hourglass — so you can keep blasting without constantly stopping to adjust your setup.
This system works with your existing SandBlastKit Pro setup, including ceramic and carbide nozzles. No compressor required — just connect it to your pressure washer sandblasting kit and start blasting with controlled, continuous media flow.

Why Most Rust
jobs never get
finished
Grinding takes forever. Wire wheels wear out fast. And real sandblasting setups cost thousands. That’s why most people quit before the job is done.
SandblastKit solves that by turning your pressure washer into a powerful wet sandblaster.
Problem 1
Grinding Is Slow
You spend hours on one spot… and still miss rust in corners and edges.
Problem 2
Wheels Wear Out
You burn through discs and wire wheels without real progress.
Problem 3
Blasting Costs Thousands
Compressors, cabinets, setups… most people never even start.

Works great !! Before and after.. 3100psi pressure washer and Black Diamond media from Tractor Supply
I am definitely happy with the results from blasting my 78' Ford frame.
Bought one 8 months ago and finally tested it on a oil pan with a bag of play sand from home depot I set the sand bucket 3’ above the work peace and it sucked up sand like it was in a hotdog eating contest. I then warmed the pan with propane to remove any moisture and primed it all in one step. Very pleased It worked well.
I completely retract my previous statement that this company is fake. Not only is this product as real as it gets. When I had doubts about a shipping mistake that happened. A real person reached out to answer my concerns and ultimately fixed any issues. They were genuine in their apology and very humble in their approach.
This might save me thousands of dollars in my classic car restoration. Honestly I'll give this a shot.
Heres a real review. I have the 3000psi kit and the 5000psi kit I bought a metal trashcan. I placed a window screen mesh on top to screen the rock from the play sand. ****VERY IMPORTANT STEP**** this prevents frustration with clogged tips. Keep the sand feed hose feeding on top while blasting. Prevents water from getting in the line when you stop spraying. Does it work 100% After you spray it will leave a gold oxidation. To remove this before prepwork you will need to use Ospho or Chemprime. A phosphoric acid which will help etch the metal for the Direct to metal (DTM) primer to positively bond. I love this thing. Yall should send me a new kit as my nozzles just about had it... i pur it through the test with my 1972 Cutlass
I have one you better be careful all your friends will want to borrow or bring stuff to you .....it mad a believer out of me I did a rim off a 1964 f350 never cleaned. 7 minutes it was down to metal
Works great! Used sifted play sand and it stripped the paint and rust right off!
I just finished a 1969 Chevelle door jams doors so forth. Messy but effective.....start the body this week. I changed the sand feed line to a larger size because it kept stopping up with wet sans close to the nosel. Small pebbles were and issue as well. Use as fine sand as you can find. Still had to sift it .The larger sand feed line made a world of difference.
I have used a couple different variants of this. It takes a decent size pressure washer and water supply to run. Also goes through media pretty quickly. That being said it generally leaves a decent finish, also you will need to make sure you have a plan to prevent flash rust after you’re finished.
I first learned about this, from watching YouTube videos about pressure washing with a sandblast attachment, and I spent less than $300 for the pressure washer and this sandblast attachment, bought a 40lb bag of media for less than $10, and a tarp to collect & reuse the media. I blasted my own 1970 GM A-body frame on a pair of plastic sawhorses, on a car trailer, in my back yard, and there was no (harmful) dust to breathe, and no mess or cleanup to worry about. My frame came out like new, I primered & painted it with rattle cans, as a driver vehicle! Best tool I’ve ever owned!
Works really good used it today was surprise how it came out
I purchased one and it works excellent without wasting sand. Although I wished I'd ordered a wet suit with it.
These work great. Only thing I recommend is to filter the cheap sand through a screen to rid it of chunks that plug the suction tube.
This WORKS!!!! I ordered mine and i was amazed at how well it worked without the dust storm and use of a large air compressor.
I feed sand to this unit using a small pressure feed pot. Works much more efficient as the sand is forced into the hose with air pressure. The suction hose does not plug up! Still dustless blasting!!! Great combination for me!
Frequently Asked Questions
Everything you need to know about SandBlastKit. Can't find your answer? Contact us directly.
What does SandBlastKit actually do, is it a real water sandblaster or just an attachment?
SandBlastKit converts your existing pressure washer into a wet sandblaster. It attaches directly to your wand and uses suction to draw sand from a bucket, mixing it into the water stream so you can blast away rust, paint, and heavy coatings from metal, wood, and concrete. Most standard pressure washers (1,500–4,000 PSI) are compatible.
No special equipment required
Which bundle do I need for my project?
It depends on the job. The Starter Kit is perfect for small projects and first-time users. The Do It Right Bundle (our most popular) adds PRO Nozzles, a Face Mask, Sand Sifter, and Rust Inhibitor — covering everything for a complete job. For heavy-duty work like full truck frames, trailers, or farm equipment, the Pro Bundle includes a high-pressure gun and cleanup accessories built for repeated, large-scale use. Not sure? Contact us and we'll point you in the right direction.
How do I set up my DIY pressure washer sandblaster correctly to avoid clogging?
Setup order matters: always pull the trigger and get water flowing before placing the suction head into the sand, and when stopping, lift the suction head out first, then release the trigger. Keep the sand hose as upright as possible (around the 12 o'clock position) and raise your sand bucket about 3 feet off the ground for better suction. Using dry, filtered sand is essential, even one damp clump can block the system. This is the single most overlooked step in any pressure washer sandblaster DIY setup.
What type of sand or blasting media should I use?
Use dry, coarse-grade blasting sand — avoid play sand or beach sand as they are too fine, too smooth, or too damp and will clog the system. Different jobs call for different media: coarser grits remove heavy rust and thick coatings, while finer grits are better for lighter prep work or softer surfaces like wood. Always run your sand through the Sand Filter/Sifter before each session to remove rocks, moisture, and debris.
How do I prevent rust from coming back right after blasting?
After blasting, bare metal oxidises fast — sometimes within hours. The fix is simple: add Rust Inhibitor to your water feed line (1 oz per gallon). This protects the surface for up to 72 hours, giving you plenty of time to apply primer or paint. If you're not coating right away, wipe the surface dry, blow air into all seams and joints, and store in a dry environment. The Mini Cordless Turbo Jet Blower is great for clearing moisture from tight spots like bolts and frames.
Can I reuse my blasting sand to save money?
Yes — with the right setup you can recover and reuse 70–80% of your sand. Place the Sandblast Catch Net under your work area to collect spent media. After blasting, rake it out, let it dry in the sun, then run it through the Sand Filter/Sifter again before the next session. Store reclaimed sand in a sealed metal container away from moisture to keep it dry and ready to use.
My blasting feels weak or the sand keeps clogging, what should I do?
The two most common causes are wet sand and incorrect hose angle. Check that your sand is completely dry (sift it first), keep the suction hose upright, and make sure the bucket is raised off the ground. If suction is still poor, adjust the black knob on your washer's pump to regulate flow. For stubborn rust or thicker coatings, upgrading to the High-Pressure Washer Gun significantly boosts PSI and gives you interchangeable tips for more targeted control.
