Alas, you've got a problem. Your beloved ukulele has a crack. You are considering taking it to the repair master, but the prices bite, so you'd like to do what you can first. Please mind that my tutorial is for small cracks only. Real wide cracks can't be just fixed with glue, so you have to take your instrument to the specialist.


  1. Figure out the cause, so that you can stop it recurring after you fix it. If it wasn't a mechanical damage and one day you just discovered a crack or a few on the surface of your uke having no idea what happened, it's likely due to a lack of humidity.
    • If you've got a solid wood ukulele, it requires special treatment, like all solid wood instruments. Get a uke case (if you don't have one already) and a case humidifier ASAP.
  2. Set a comfortable working area - any table will do. Cover your working surface with an old newspaper or something to protect it from accidental drops of glue.
  3. Place your uke on the surface, crack up. If the crack is on the side, then you'll have to use your knees as such.
  4. Clean the uke. Wipe away any dirt, oil, or whatever might have stuck to your uke during its use with a clean, slightly wet piece of cloth. Wipe again with a clean dry cloth.
  5. Get your glue, whatever it is. Some people use a special wood glue that is widely used for the musical instrument repairs; you can look the brands up online. Some prefer hide glue, but it's a lot of work to make it. It comes in dry crystals and you have to actually "cook" it.
  6. Apply glue to the length of the crack. Extend it a bit further on both sides. Make sure it coats the crack well, but don't pour too much.
  7. Tap the glue into the crack with your index finger. All the way down the crack and back, and repeat a few times. That will allow the glue to get into the crack even if it's very small.
  8. Give the glue 10-15 seconds to soak in. Then remove the remaining glue from the surface of the instrument with a wet (and well-wringed out) piece of cloth. Make sure to wipe the uke well, because the remaining glue might leave slight traces when dried.
  9. Let it rest for 15-20 minutes. Then put it in the case with a humidifier. It's usually recommended that you don't touch the glued details for 12-18 hours, so just leave it in the case.
  10. You're a happy owner of a fixed uke!


  • Over-humidity is also bad for any wooden instrument. So make sure the humidity level where you keep your uke is around 45-60%, no more (and no less)!
  • A regular case humidifier costs around 7-8$ and works well enough. You can find those online or in most music instrument stores. You need a humidifier that comes in size for small string instruments, like a violin, a mandolin, and a uke.


  • First examine the crack. If it's too big and wide you might consider taking it to the professional.
  • Careful with glue - make sure to wash your hands and wipe the ukulele's surface shortly after you apply it.

Things You'll Need

  • Special wood glue or hide glue (make sure you want to bother with hide glue before buying one).
  • A piece of wet cloth to wipe away the glue
  • A uke case and a case humidifier, if the reason your uke cracked was lack of humidity.
