LOCA Pro Tip | Spidering

Posted by Kyle C. on

Uncured LOCA under your GameBoy Color or Gameboy Advance frontlight's reflective tape can cause an issue known as spidering. This terms is used to describe the cracked, hazy and just plain unsightly lines that appear under your frontlight panel. Worry not, there is a way to help prevent and to fix this problem.

One of the best things you can do to prevent spidering is to remove the front and back reflective tape and cure the LOCA underneath to prevent uncured loca from leaking and the panel from flexing after installation. The bottom area of the frontlight panel hold LOCA that will succumb to gravity if not cured. UV light will not penetrate the silver reflective strip. Once you cure the glue underneath, replace the reflective tape to remove some of your hotspots. This will help eliminate defects and keep your frontlight application perfect. This step will be important for the GBA frontlight as you have a longer area of tape and uncued LOCA to deal with. There is less space in the GBA case as well so a little extra prep work will keep your install flawless for years to come.

What are some of your methods for installing frontlights? What have you found helpful in creating a lasting LOCA bond?

  • “You can remove the frontlight and reapply the loca for a second go at it”

    This might be an obvious question, but I truly don’t know: how in the world do I remove the frontlight, once it’s glued to the screen with LOCA? I have the spidering problem, and I’d like to try again.

    Also, related question, I got the LOCA from the store, and now I need an UV light, but I’m not sure which one. What UV wavelength to you recommend for the LCOA from your store?

  • I have a question. I’ve ended up with spidering on two different gbc frontlighting attempts after using the generic loca from this site. I know some better loca application and curing techniques now, but I really don’t want spidering a 3rd time. Does using Osaka brand loca instead of the generic loca significantly decrease the likelihood of spidering? I’m currently trying to decide if I should buy Osaka loca before trying again.

  • Daryl, Are you removing both the back and front reflective strip?

  • So I’ve gone through two frontlights for my GBC and I continue to get spidering problems. I’ve done this trick with removing the strip at the bottom and then reapplying it, but it just keeps happening. I don’t have a UV kit, so I place it in my backyard for over an hour to cure. Is there any suggestion to help get this right? I’ve got enough LOCA left for one more try, and if that doesn’t work I’m just going to give up.

  • You can remove the frontlight and reapply the loca for a second go at it. Remove the bottom reflective tape as well to cure even more. That is no problem.
