Repair an Exposed Wire With Sugru





Introduction: Repair an Exposed Wire With Sugru

The black casing on laptop charger cord broke and I could see the inside wires. When this happened to my last charger it broke soon after. Sugru is a great way to cover up these wires and keep my charger safe and working!

Step 1: Exposed Wires

I am constantly bending and wrapping the cord and throwing it in my backpack.  It if only a matter of time before the white and green wires broke as well.

Step 2: Add Sugru

This step is simple.  Just open up the Sugru and spread it out over the exposed area.  Make sure it covers the entire exposed area!  Let it sit for 24 hours (make sure you don't bend it).

Step 3: All FIXED!!

    I would use shrink tubing . It comes in many sizes .You heat it and make a
    durable & waterproof seal .

    Heat shrink tubing of a diameter large enough to thread past the end connector would not shrink down sufficiently to have a firm wrap around the area.
    Maybe you have a solution to the problem ?

    Then split insulation off another piece of wire put it around the compromised wire, and shrink wrap over all of it. Still a better fix than this nonsense.

    I' d use a good grade of electrian's tape or when it happened
    to my ear buds I used some PTFE thread sealing tape that
    plumber use , it sticks to itself and isn't messy Wil

    Epoxy putty from the local hardware store is cheaper I bet. Also the bond would be stronger, you could put a decent wad of epoxy putty around that and it would provide cord strength through adhesive power, I think sugru might have less bonding strength since ive seen folks peel that off. Putty isnt flexible but that is ok for a small segment, just put a small mound of it on.

    You can buy at auto parts place a blue (maybe other colors ) coating made for coating tool handles, I use it for insulating wires and tools handles, great stuff

    This is very interesting, but what is Sugru? We don't have it in the UK and I assume it's something you mix by kneading, like epoxy metal? I'd hate to use the wrong stuff and explode something!

    Obviously the "owners" of Instructables know what Sugru is - they have a "Sugru Competition" (just see the links to the right of the page!)

    I must admit that this Brit had never heard of it either - must investigate!

    I live in the UK as well and had never heard of it before this post but a quick web search showed me that is available here and sounds interesting.

    I've just ordered 12 wee packages for £11.74 delivered to my door, so will comment no further until I've tried it...
