LE LEMATEC Sand Blaster Gun Kit for Air Compressor, Pistola de Arena | Portable handheld sandblaster, ceramic nozzle, 90 PSI 4 CFM, rust paint removal, auto restoration

Great little unit for the price. Used it to clean a few small parts on a car restoration that were proving difficult to sand by hand before paint. Have used it on a verity of different parts now mostly because it’s way more convenient and quicker to use this rather then trying to sand them by hand. I’m sure it would work fine on a larger scale job but would obviously take a long time. It’s perfect for the smaller jobs. Update! I just rd painted the front doors to my house that have some complicated trim pieces all over it. Sanding the flat surfaces by hand is obviously easy but I did not want to spend hours getting into the nooks and crannies sanding by hand. Used this to do it instead. A few hours job turned into the whole door being ready in about 30 minutes.

This blaster is fantastic. It was super easy to use and does one heck of a job with 120 grit aluminum oxide powered by 140 psi out of my 15 gallon Dewalt compressor. Even though I was doing 5 small jobs, I had to refill the hopper three times. I was not filling the hopper full, about 2 cups of media each fill, and soon realized I should have gotten the siphon blaster. That said, I could not be more pleased with the job it did. I must say, out of the box I was not impressed, but after using I am wondering what took me so long to get one. It ate rust and epoxy based paint with ease, leaving a beautiful matte finish on stainless steel and a surface ready to paint on regular steel. If you’re one the fence about getting one, do it, but strongly consider the unit with the siphon.

Does a good job for the price

I purchased this gun to replace a gun I purchased last year that just was a real pain to use. This gun has performed flawlessly. I've used it primarily to clean motorcycle parts and outdoor ornaments. Easy to set up and light weight for moving around with. My only complaint is that the airline connector included was not the right one for a quick connect 1/4" setup. I replaced it with a spare that I had here from other air tools. It is easy to fill and with the two different nozzles and the flow adjuster it has proven invaluable. Being a gravity fed instead of a siphon gun your only connection is the air hose which makes it quite flexible in where and how it is used. Great bang for the price!

I used it to remove finish and stain from the recessed areas of 26 raised panel maple cabinet doors using "fine" walnut shell media. The walnut shell media specify a mesh size but seemed to be appropriate. The work was slow, taking about 2 days, but I don't know of any other way to do this job since I was refinishing in a lighter color. Used a 4.8 cfm at 90 psi compressor which was minimal - I had to wait for it to catch up periodically, but used that time to dump more media in the hopper. It is important to use a water separator, about $10, and it works best on dry days. I found one made from clear plastic with a schrader valve for releasing moisture buildup. Still the blaster would gum up occasionally requiring disassembly. Note that they seem to make the connections opposite from what you would need to attach the separator directly, requiring adapters on either end! The hopper empties quickly - the job would go much faster with a larger hopper or a blasting cabinet large enough to accommodate the doors, with a suction type blaster. I am guessing this would require even more air volume. The media goes EVERYWHERE! Do it outside on a 20' x 20' tarp and plan on recycling the media many times. That or build a large enough blasting cabinet to accommodate your project. Use full protective gear including long sleeves, canister type face mask, face shield, and gloves. Still the media winds up in your pockets, shoes, ears, etc.

This thing is way better than expected. I ran play sand like you shouldn’t and ran it off a small pancake compressor. Also like you shouldn’t. I sifted the sand with a window screen and it worked great. Had to stop a few times here and there for the compressor to build back up but it works great. Way better than the cabinet blaster I use at work. This seems to be more consistent with the delivery.

Product description claimed it ran at 4cfm.... Opened box to discover it requires 7cfm.

Very good quality, it was what I was waiting for, I used it and it works perfectly, good material and good finishes, I recommend it 100%.

Merits: This is portable blaster. Serves the purpose to blast a small or spot touch ups. Demerits: very expensive and no details provided to procure the consumables like ceramic nozzles etc.

Works well thanks

Works very well, I use kiln dried sand…no problem whatsoever, also used 0.5 professional sand and no wear after 5 hours of continuous use….it’s very good design so far! Will update after a few months

I took a chance and tried sandblasting for the first time with an air compressor that delivers 4.5 CFM @ 90 PSI. I thought it would give mediocre results, but it exceeded my most optimistic expectations. I used 120 grit fine aluminum oxide. It works quite well! I would not go north of a project bigger than one square foot, or bigger than a single car rim or brake drum, as this would be way too slow and tedious. But if you have just a couple of inches of area to rust off/sandblast, it works great. Perfect for a car with just a couple of rust spots to remove.
