xTool Black Laser Marking Spray, 1pc, 8.5 oz - Advanced High Contrast Formula for CO2, Fiber & Diode Laser Engravers - New & Improved Version

5 stars for quality, ease of use 5 stars for coverage 4 stars for cost effectiveness Can is smaller than other brands for the same price, but I figured I’d give it a shot since it’s the xtool brand. Worked well enough, but the Cermark brand is just fine in a bigger can for less money. Might not cover as well as xtool brand and require a couple more passes. Xtool brand did a great job to cover effectively

I run a laser engraving and cutting business and have used this spray on both metal and plastic with excellent results. It’s very easy to apply — just make sure to use it outside or in a well-ventilated area, as the fumes are strong. One thing to note is that while it's called a “black” laser marking spray, it actually sprays out with a yellow tint. That said, the final engraved marks come out black, crisp, and clean, exactly as expected. It doesn’t degrade the quality of the materials I’m engraving on, and it’s been surprisingly long-lasting — I’ve been using the same can for a couple of months across multiple projects, and there’s still plenty left. Definitely worth the investment for anyone doing precision laser work.

This spray helps produce a dark black engraving. It comes with detailed instructions. Two "I wish I had known that" moments: 1. The spray doesn't act like paint. If you touch it after it's "dry", it comes right off. It's basically a powder. Found that out the hard way. Doesn't affect utility. 2. In a video about the product, they mention a very specific way to shake the can: keep it horizontal and only shake about 1 minute. This instruction is not in the directions. Solid outcome. Will buy again.

Pricey, but works well. Glad we don't need it often. Try a few of them to see what works best.

Best spray on the market , my jibs have been comjng out soo much better with this then the black paint markers.

It may be user error or maybe I just don't know how to use this stuff but when I tried to use it, it literally wiped right off with the slightest touch. I couldn't even get it to stay on long enough to try and engrave over it ....

Works awesome on glass when using a diode laser. Made amazing etchings on the glasses I was engraving. Washed off really easily with just a little water. Easy to use if you follow the instructions just spray an even coat on the part youre engraving and let it sit for 10-30 mins and it is ready to engrave your parts.
