Strapping a Mask Using CosBond from ZakLabs

CosBond is Offering Some New Solutions

Every costume that is made has always brought about new challenges on how to attach items to each other! Especially with strapping for masks, gauntlets, and/or floating armor pieces that have no visible connection points to a suit.

We visited Zak Labs at Emerald City Comicon and were introduced to a new adhesive called CosBond.

CosBond comes in adhesive sheets that saves time, is very strong, and doesn’t have the usual mess/inconvenience associated with other materials such as hot glue, super glue, and contact cements. While those materials mentioned are extremely useful there are times when they are not as practical as we would like. Billythebrick Cosplay told us one main purpose is to have adhesive that is much more transportable for convention repair, and I definitely see the benefit of that.

With a Cosbond sample pack in hand, I wanted to test it on something I do quite often and have been searching for: an easier, quicker, and cost-saving method of attaching strapping to a mask.

Mask Strapping Tutorial

The following is a tutorial for how I used a sample pack to strap up one of our masks we produce. With any project, it’s all about the prep.

Prepare the areas for CosBond adhesion

  • To start, clean the areas that the strapping will be adhered. I recommend using isopropyl alcohol. This will remove any residue of oils or paint left over from the casting and painting process.
  • Now, score and rough up the areas as this will allow the CosBond, when applied, to adhere to the plastic better.
  • Rub off an excess dust from the scoring. Then, proceed to mark off where you plan to attach strapping.

  • Now, using your markings on the mask as a guide, cut CosBond strips to your required size.

  • Peel off one side. It doesn’t matter which side you peel off first. We will peel off the reverse side when get to the strapping itself.
  • Apply the strips (obviously the adhesive exposed side) to the mask and press firmly for only a second. This will promote proper adhesion.

  • CosBond does not require clamps or excess pressure (at least from what it instructs and what we’ve experimented with).
  • Put the mask aside for a moment as you move on to strapping.

Using CosBond to Adhere the Strapping Together

  • Cut all the strapping to you’re required size. Prepare with needed hardware (buckles, etc.).

  • Grab a strap piece and slide your hardware on (if needed).
  • Peel off one side of a new CosBond piece. Adhere to one side of the strap.
  • Next, peel off the other side and press the strapping firmly together, as pictured, to hold the buckle within the strapping.

  • The buckle will be held in tight to the strapping!

  • Bring your mask that you had set aside back. As CosBond is clear, the picture below just highlights why marking is so important in making adhering objects together so much easier.
  • If you don’t already have CosBond on the section you need to apply the strapping to, do so now.
  • If you already do, all you have to do is peel off the other sticker and apply your strapping directly to your mask with firm pressure.

  • You strap will be attached nice and tight as seen below.

  • The rest of the strapping was adhered as above. Rinse and repeat. It’s that easy!

Reinforce Your CosBond Adhesion

  • ZakLabs recommends using reinforcing tape to add an extra layer of support.
  • Cut reinforcer to size.

  • Use the flat tip of a marker pen (or what you prefer) to help get a nice and tight bond to the strapping.

That’s it! Your project should be finished and ready to wear. No need to wait for any drying. You can also do a “swing test” to make sure everything is adhering as it should.


I got a mask strapped inside of a few minutes, that was ready-to-wear without having to wait for glue to set or fumes to dissipate.

CosBond is great, especially if you do not have a work shop, or work inside your home where fumes can be damaging to you, pets, etc.

(Plus, no burned fingers from hot glue!)
