Recently while looking through Rock Climbing: Mastering Basic Skills by Craig Luebben, I read that you shouldn't put stickers or paint on your helmet because it undermines the strength of the shell. Any idea why that is? Is it even true? Kevin Brooks Henry

There could be a chemical in the adhesive or paint that weakens the plastic. Unlikely, but possible. I have stickers on my helmet. Ryan Williams

In construction we have this issue with hard hats. Paint is a definite no-no; but the idea that stickers weaken it is generally dismissed as a wives tale. What the safety guys do state regarding stickers is the possibility of hiding a defect or damage. Mike Lane

This is ridiculous. Sorry, but total BS. Sure the adhesive may have a chemical in it that may weaken the shell in the slightest bit, but I can't believe someone would honestly say a sticker caused failure of a helmet, not the whipper they just took or the rock that fell from above. usernameremoved

And yet on every site you go to you have to sit through a couple of hours of safety training just so they can put a sticker on your head saying you passed their safety instruction...

I doubt the ability of the adhesive on the sticker to weaken the integrity of your brain bucket.

if you take some time to google this, you will find this largely unfounded from both the construction standpoint as well as climbing.
As stated, stickers hiding defects and cracks is a valid point. So make sure you know the status of your pot, and inspect it frequently.

In construction they do not like you to have metallic stickers within an inch of the brim because of (maybe also unfounded) concerns for elctrical conductivity.

besides, how do you tell your identical make and model helmet apart from everyone elses?

Heh...tell that to the dude with the shiny metal (looks like aluminum) hard hat at the construction site at the local high school!

Well judging from the dozen or so stickers on each of my helmets, I'm a dead man next rock I catch. Woodchuck ATC

Crux?
I am not a huge fan of being a billboard or an indicator species for that matter. I had a half dome suck up the impact of a toaster oven sized block and it performed really well. Give the stickers to your kid or your neighbors kid and go climbing. After all it's about doing it, not being a pawn to marketing. Daniel Crescenzo

Climb alone. Except with Wilson on my helmet!
Think.

Paint could change to Styrofoam strength. Would it change the plastic? Stickers could hide things like damage.

What have you done to your brain bucket?

Nothing, just thought it was an interesting warning.

The funny thing is some jobsites require stickers to be on the job, as well as some union requirements to be performing certain tasks.

Somewhat funny story in my life; I was pounded on by an all-knowing safety guy, who had a series of qc problems from his dumb-ass & lazy incompetence. One day I had enough, I asked the safety guy if he ever actually produced anything substantive toward completing a project in his career.....(he actually got shown the door, and the const mgr wanted me on board after my contract was completed due to a turn around in safety, quality of const, & efficiency; but my life was meant to be in a different direction). It still seems I certainly do have a way of making a good point, though only in a bad way.


I have no idea why stickers are perceived as a chemical reaction issue to the extent that the shell would actually be weakened.

The following is from the instructions for the Petzl Meteor III :

WARNING: Stickers, markers, paints, etc. may contain ingredients that can damage the helmet and reduce its protective properties. Before applying any of these products to the helmet, verify their compatibility with expanded polystyrene and polycarbonate

Similar warnings are given for the Elios, Altios, Elia, Picchu, and Ecrin ROC--the details of the message varying with the materials used in the helmet.

Edelrid says:

Paint, solvents, adhesives or self-adhering stickers may only be applied in keeping with the manufacturer’s instructions.

Black Diamond says:

DO NOT paint your helmet.
Stickers may have adhesives that can degrade the helmet shell material. Contact Black Diamond or your Black Diamond retailer to obtain stickers approved for use on your helmet.

Me Starting Montazuma's Tower
Damn sucks for all my belayers. I just bought a preowned helmet that had a sticker on it...

Oh well if they are climbing with me they led a good life...

Also JP that stickers saying not to use stickers is clearly hilarious.

Climbing at Frog Buttress
As a rider of motorcycles for much of my life, I had heard that you shouldn't put stickers on a motorcycle helmet because it compromises the ability of the slick helmet surface to slip across the ground upon impact.

Rather than the chemicals in the sticker affecting the material, it's the friction of the surface of the sticker itself that binds to the road surface when your head hits/slides along the road. If the sticker (and therefore your whole head) bites into the road surface, the momentum of your body could break your neck.

Not sure if this would transfer to the physics of a fall in climbing since you're falling downwards mainly, but maybe a sticker(s) could prevent a rock from glancing across the helmet?...dunno.
