How to fix a zipper that Separates?

If your zipper has separated, don’t panic! This is a common problem that can usually be fixed quite easily. In most cases, you will need a pair of pliers and a little patience.

Standard Method

  • First, gently push the zipper’s two sides back together. If this doesn’t work, you must use the pliers to realign the teeth. Start by opening the pliers up slightly and then insert them into the gap between the two sides of the zipper. Gently squeeze the pliers until the teeth are lined up properly, and then try to zip the zipper up again.
  • If this doesn’t work, you may need to replace the zipper slider. The slider is a small metal piece that moves up and down the zipper track. If it is damaged or missing, then the zipper will not be able to function correctly.
  • To replace the slider, first, unzip the zipper completely. Then, locate the end of the zipper tape attached to the slider (this will be on the side of the slider facing away from you). Carefully cut this tape, careful not to damage the zipper teeth.
  • Next, thread a new piece of tape through the slider and reattach it to the zipper tape. Make sure the new piece of tape is the same length as the piece you just cut off. Finally, zip the zipper up and down a few times to ensure it works properly.
  • If your zipper doesn’t stay together, you may need to replace the entire zipper. This is a more complicated repair, but it is still possible to do it yourself. You must purchase a new zipper and follow the instructions above to install it.
  • If you are still having trouble, you may want to take your garment to a professional tailor or seamstress. They will be able to help you choose the correct size zipper and install it properly.

How to fix a zipper using a screwdriver?

One of the slider’s teeth may have come loose, so a screwdriver may be used to reattach it. If the slider and pull have detached from both sides of the teeth, you can try this method instead.

  • Gather a little flathead screwdriver and go from there.
  • Then, you need to find the zipper’s bottom end. The bottom of a garment is the end that rests against your feet, but the bottom of a bag or other item is the side with the most teeth on the right when looking at the front zipper.
  • Put the pull’s wider end through the bottom’s stoppers. If you don’t orient the pull properly, it won’t be able to pass over the teeth.
  • Most of the time, the teeth won’t be able to slide back into the pull without some assistance. Use your small flathead screwdriver as a lever to get them back in the slider on each side.

How to fix a zipper using Tweezers?

Simple tweezers can also come in handy when mending a broken zipper. Tweezers’ multipurpose nature makes them useful for a variety of fixes:

If the slider has become dislodged from the teeth, you can put it back in place by using tweezers to push the teeth into the slider’s wide end, followed by a pull in the opposite direction to reconnect the slider to the zipper. This approach provides more precision than a screwdriver and could be more effective.

Use tweezers to pry out the thread or other debris that may have gotten caught in the slider if the pull becomes hung up on the teeth.

In a pinch, you may also use tweezers to reattach a loose slide’s top and bottom plate by gently pressing them together. If your zipper keeps coming apart, doing this will assist the teeth in meshing together again.

How to fix a zipper using nail paint?

A standard method is to paint the teeth with clear nail polish if they seem worn down from overuse (yes, it occurs). The teeth will be adequately thickened, and the zipper’s functionality may be restored. If, after applying the first layer of polish, you still cannot get the zipper to close, you may choose to apply additional coats.

Why Do Zippers Break?

Zippers are one of those things that we often take for granted- until they break. Then, we’re left wondering why they failed us and what we can do to prevent it from happening again.

Below, we’ll explore some of the most common reasons why zippers break, as well as provide tips on how to avoid zipper failure in the future.

One of the most common reasons for zipper failure is simply due to wear and tear. Zippers are made of small, interlocking teeth that can become damaged or bent over time. 

This damage can be caused by frequent use, catching the zipper on clothing or other objects, or storing the zipper in a tight space. 

Once the teeth become damaged, they may no longer line up correctly, which can cause the zipper to jam or fail altogether.

Another common reason for zipper failure is improper installation. If a zipper is not installed correctly, the teeth may not line up properly from the start. 

This can cause problems down the road, as the zipper may become more difficult to use over time. It’s essential to follow the instructions carefully when installing a new zipper and ensure that the teeth are correctly aligned before closing the zipper.

Finally, zippers can break if they are overloaded. This is often the case with backpacks and other bags designed to carry a lot of weight. 

The teeth can become bent or pulled out entirely if too much weight is placed on the zipper. This can render the zipper useless, so it’s essential not to overload bags with too much gear.


No matter how careful you are, zippers will eventually give out. When that happens, it’s good to know how to quickly fix a zipper that separates. The steps we’ve outlined should help you do just that and have you up and running in no time. Have you ever had to fix a zipper? What was your experience like? Let us know in the comments below.
