Traditional bandages for wound care usually consist of a small piece of sterile gauze held in place by a thin adhesive strip. There are times, however, when a standard bandage is not as effective for wound protection. The injury may be too large for a bandage to cover, or it may be difficult to seal off. In cases such as these, many people choose to use a special tapeless and gauzeless wound sealant known as a liquid bandage.

A liquid bandage is essentially a self-curing adhesive which uses the same basic principles as so-called super glues. A special form of acrylate glue is mixed with chemical stabilizers and curatives to form a liquid adhesive which bonds well with human skin. As the bandage dries, it forms a protective polymer shell over the injured skin.

Cuts and scrapes which cause long thin breaks in the victim's skin are especially suited for liquid bandages. The solution can be carefully swabbed over the entire length of the injury, forming a protective coating which would be difficult to duplicate with regular cloth or plastic bandages. Injuries in areas which flex or stretch, such as joints or fingers, also benefit from the flexibility of these types of bandages.


Surgeons and other medical professionals also use a more advanced form of liquid bandage as a substitute for traditional sutures. If an internal wound can be sealed with a biodegradable polymer instead of thread, the chances of a post-surgical infection are often reduced. Minor gashes and punctures which would ordinarily require a few stitches or butterfly bandage to close can often be effectively sealed with a form of liquid dressing instead.

Many health experts actually prefer the use of liquid bandages over traditional gauze bandages in certain situations. The bandage solution actually flows into the injured area and bonds with the edges of the laceration, something a standard gauze bandage cannot do. Traditional gauze bandages may also fall off during physical activities or lose their adhesive qualities over time, leaving the wound exposed to bacteria and other contaminants. A liquid one flexes with the patient and should be water-resistant if not fully waterproof.

Many drugstores and pharmacies offer over-the-counter liquid bandage solutions alongside traditional gauze bandages, gauze pads and medical tape. It is important to read and understand all of the instructions provided with the solution before applying it to an open wound. Some of the chemicals may sting or burn immediately after application, but the bandage should cure within a few minutes. Some cuts and scrapes may require additional bandaging in order to prevent infection, and a liquid bandage should never be picked or scraped off an unhealed wound.

As a great first aid open wound protector it, as dipped from the container over time, of course gets lower in the bottle and it becomes thicker. When it is very thick on the application brush, the glob is difficult to "paint" with any satisfaction. I tried using a little isopropyl alcohol to thin it back to normal. No luck. Anyone know how to thin it before it's too thick, and then have to throw away the remainder?

This stuff is great (when it is thin) and is good to also paint over skin flaps, small warts, and pre-blister spots on skin.

When applied to an open wound it will have to sting, a little, but just for a few seconds. I welcome the brief mild stinging as it is making things better.

@ FrameMaker- I used to work in forestry logging, clearing brush, and landscaping. The crew I worked with always kept a tube of super glue on hand when we were working at a job site. Super glue was the original liquid bandage, and works just the same as liquid skin bandages (maybe it is a little more toxic though). You are right...the stuff works great at closing up deep cuts (always a risk when you are working with chainsaws and sharp sticks). It also does a good job at keeping dirt, diesel, gasoline, and other things out of cuts.

Liquid bandages are great. I used to work in a kitchen, and we always kept a bottle of liquid bandage in our first aid kit. The stuff was better than band aids. Liquid bandages let us get right back to work after suffering a deep cut, and it stops bleeding fast. Getting a cut on a finger joint can be debilitating in a kitchen because it will split open every time you bend your finger, but liquid bandage forms a flexible waterproof seal that keeps the wound clean and the kitchen sanitary.
