Do you know a good masking tape for laser cutting

I’m using this masking tape.

but it’s out of stock now… Do you know any good masking tape instead of that?


A quick search for masking will find a ton of threads on this, but this one is my favorite:


I get mine from here:

I use the 6" exclusively now. I tried the 12", but most of my stuff is small enough that the 6" works better, and the one roll of 12" I got was defective, and wouldn’t stick. It actually started a fire in my laser, from curling up while it was cutting, and the loose corner got hit with the laser beam. Scary. I don’t know if it was a fluke or not, but I have since stuck with the smaller roll, and had no issues.

So you might be right, but there are a couple of things that might be at play here – lower-tack tapes like this need to be pressed down with a tool, and even then how well they adhere is based on the material. How smooth your wood is will affect this a great deal.

So yeah if you still have it you might want to try it again. Make sure your material is smooth and clean, and use a tool to press it down (a straight edge scrap is fine as a test, I like a 3M plastic squeegee myself).

For a quick second I thought that was toilet paper!

I got my tape from here. i got trhe 12" x 100 yds

I used a Pampered Chef plastic scraper that I stole from my wife for this purpose, and all my wood is sanded and finished prior to engraving. It’s pretty smooth. I tried the 12" roll on a number of different surfaces, too. It simply did not stick as well. If I recall, the 12" is medium tack, while the 6" is low tack–yet the 6" works better for me. I also still use that plastic scraper. :smiley:

So one other thing I’ve heard is that adhesives have a shelf life. In theory a really old roll of masking could lose its tackiness, maybe you were sold a roll that sat in a warehouse for years? I dunno, sounds like you got a bum deal.

I’ve had nothing but good luck with Perfectear Plus. I have both a 6" and 12" roll, like you said, sometimes 6" is easier or more efficient to work with.

Different brands behave differently, but even low tack can work just fine. It often depends on surface preparation - which is one reason it’s worth paying for proofgrade materials, if you don’t have the ability or time to prepare materials for masking when necessary.

That was the issue, I think. When I talked with their customer support, first off, they were very helpful, and eventually I got a refund, but they also said that it is possible that the roll I got was simply old when they shipped it.
