Installing vinyl graphics on a glass window can be challenging. You can try both wet and dry applications, but you may get the same maddening result:  the vinyl comes off when you remove the transfer tape.


Prepping Glass for Vinyl Installation

If you are having trouble getting vinyl products to adhere to glass, you may not have prepped the substrate properly.  Here are a few steps to ensure a good glass-vinyl bond:

  • Remove oil film from the glass. Oil prevents adhesion.
  • Clean the glass with 70% isopropyl alcohol, not with ammonia-based products. Ammonia-based cleaners can cause premature drying, which will crack the acrylic adhesives.
  • Also, do not use 90% isopropyl alcohol because it will leave a residue.
  • If you are prepping tempered glass, there may be remnants of the silica film on the surface, which will act as a barrier between the glass and the pressure sensitivity vinyl film. Apply the vinyl dry onto tempered glass. Do not use a wet application; it will take forever to apply and dry.

Ensuring that the glass surface is free of dirt, oil, and silica is the key.  Follow the steps above, and you should be able to achieve a sturdy bond between the vinyl and the glass substrate.
