OMTech Laser Marking Spray, Metal Laser Marking Fluid for CO2 Laser Engravers, 4Pcs 13oz Aerosol Spray for Black Laser Engraving Metal, Laser Ink for Aluminum Stainless Steel Brass(4 Pack)

I have used this marking spray a few times and each time it has worked perfectly. This spray is advertised for use with 25w and above CO2 lasers. The laser I have is an xTool D1 Pro, 10w diode and it works perfectly fine. Just follow the instructions on the can and don't cut corners. The spray that is left after the laser process cleans off easily under water at the sink.

I bought the spray multiple times for my laser engraving projects. Material dries quickly and goes on smooth. All my projects have turned out excellent and I’ve had no issues. The price is worth the product when you know it’s gonna be correct every time.

I bought this because of the reviews that say it will work with a 10 watt laser. Tried it and it worked great. Applied a coat to a pair of ratchets. Taped them to my lasers bed one at a time with some masking tape. Set the laser to full power and a slow speed and let it rip. Worked perfectly.

Laser marking on metal for hobby lasers that are not powerful enough to cut into the metal is a great workaround. You should test before setting the speed/intensity to avoid ruining your project. Ask me how I know. Works well once you have done your research. Durable finish

I didn’t expect a spray can to change what my laser could do—but this one kind of did. I’ve always known my CO₂ laser isn’t meant for bare metal. Stainless, aluminum, brass—normally it just reflects or lightly etches at best. After trying the OMTech Laser Marking Spray, I went from “not possible” to clean, dark engravings that actually look intentional. The Moment It Clicked The first time I wiped off the excess coating and saw a deep black mark left behind, it honestly felt like cheating. It bonds during the engraving process, so you’re not just discoloring the surface—you’re leaving a durable mark. It’s More About Technique Than the Product This isn’t a “spray and magic happens” situation. What made the biggest difference for me: Light, even coats (too thick = muddy results) Letting it fully dry before engraving Dialing in power/speed settings per material Once I figured that out, results became repeatable. Where It Shines (Literally My Use Cases) I’ve gotten the best results using it for: Tool labeling (no more stickers peeling off) Small metal tags and plates Custom branding on parts It’s especially satisfying on stainless—super crisp contrast. Not Perfect—But Close Enough It can get messy if you overspray, and cleanup is part of the process. But compared to buying a fiber laser? This is a no-brainer workaround

I know this is supposed to be used to mark metal but I use it to etch glass. I have a 10 watt diode laser and even though it isn't necessarily used for glass it works well for it. it is easy to use and coats the glass well. I throw it onto a rotary tool and use my laser to etch designs on to rocks glasses for my friends and family! if you figure out how to use it lightly a little can go a long way!

Great for the ceramic coasters I engrave! I do 2 light coats. It washes of easily with water.

This laser marking spray is just okay, not too durable and I think it is overpriced for what you get. It gets the job done eventually, but the manufacturer's instructions are a bit flawed and will result in your design being completely erased if you follow them exactly. First, the spray comes out with a bang making it near impossible to get a thin, light even coat, all mine came out heavy. Short of that, everything went smoothly following the instructions up until Step #6, which instructs that once engraved, carefully remove any debris with water or a soft cloth. The first time around, right after engraving, I rinsed the white spray residue off and used a soft cloth to dry the water. As you can see in the picture of the stainless steel flask, the black markings immediately wiped right off with the water. I stopped and took a picture then continued to wipe, and the black came completely off. I thought it was the stainless, but the same thing happened on the bamboo board. I worked with it a few more times and found a more reliable post-processing method, and it worked: - first, engrave your piece with two passes - twice what you would normally use without the spray making the engrave a bit deeper than normal. Gently rinse the excess white spray residue under cold, running water. Do not touch, rub, or wipe the design at this stage. Let it air dry completely. Do not use a towel or cloth to dry it. Wait 24 to 48 hours. I noticed that after 24 hours, a tiny bit of black would still smudge if touched. However, after letting it sit and cure for a couple of days, the black marking locked in place and stayed permanently, even when wiped down firmly with a soft cloth. Additionally, it lightened the color of the bamboo cutting board, but the stainless steel flask was not affected. Bottom line: The product can permanent-mark, but the chemical bond needs time to settle after being hit by the laser and expect color change in a wood project. Having to do two passes doubles the processing time and letting it set for a couple days lengthens the time to complete a project and get it out the door.

Better than Brilliance brand.

Ce produit est idéal pour la gravure sur aluminium anodisé. Je le rachèterai sans hésiter pour mes prochains travaux de gravure.

3 stars because the product itself worked pretty well. I wish I’d taken some pictures, but it was a rush order (with how late the spray arrived) and I just had to get the product out the door. Prior to spraying, I cleaned all of the materials, 25 steel dog bowls, same design, same set up etc. I sprayed each bowl the day before I used the laser, approx 28 hrs before I used the laser on them. That said, they looked dry only minutes after I sprayed them, ensuring an even application. **PLEASE NOTE!! The nozzle somehow got stuck “on” and continued to spray despite the fact my finger was not even on the nozzle any longer. It would continue to spray for a good 2-10 seconds before stopping. This resulted in a fair amount of the product being wasted. After the first few times of it happening (cause it was not doing this consistently, making it harder to predict), I took the cap off to see if there was anything I could do to clear it out or stop that from occurring again. There was nothing that I could see that was obviously causing that issue. To be honest I didn’t have too much time to sit an inspect/troubleshoot, so I ended up just trying to have additional bowls ‘ready’ on a jig so if it was continuously spraying and not able to stop it then it I could at least get some of the product on the outside of the bowls. That was kind of irritating, given how pricey this stuff is, and how long I had to wait- with rush projects to get done. I also noticed that there was some areas that were lasered (again, same settings design and material, even coats of product) that appeared ‘pitted’ or bubbled somehow. Whether this is an issue with the product or the material is an unknown to me at this point, as I don’t have enough experience to say. As I said, it took a long time to get here (YYC, AB) and it’s painfully expensive, especially when considering how much was wasted to a faulty spray mechanism at the top. If I could do half stars I’d maybe do 3.5 ⭐️ . If there was no faulty spray mechanism costing me wasted product I’d give a 4 ⭐️ if there was better shipping time, price and no inconsistency in the laser result I’d give a 5⭐️ If anyone is wondering, as I was - I was using the Xtool F1, with the 10w (Blue) giving the best result, I used 75% power due to the material being sort of tricky, and 230 for speed and it seemed to do the trick on a stainless steel dog bowl from Princess Auto. I highly, HIGHLY recommend ordering extra if you have a project that you are unsure of how the material will do, settings, all of that, and that you make time and allowance to play with the best settings for your project. I used another product recently (shipped in powder form) that was NOT GOOD, and it stated no where on the page or pictures that it was meant for co2 lasers only. I found out only after I opened it up and read the instructions for mixing. So, my advice is make sure that the product works for the type of laser you are working with because YES, it does matter!
