After receiving an inceasing frequency of customers asking for DO IT YOURSELF window singage for their offices or shop windows we have decided to write a post and we will point people to this.
Applying vinyl to glass, and specifically vinyl lettering to glass is not simple. We have seen plenty of websites that say how easy this process is, and for some situations it might be okay for self installation- but in general- using coloured vinyl to create lettering does require a certain level of installation skill.
If you really want a professional looking glass signage application we recommend using a sign writer or professional installer. This vinyl lettering below was installed by Cool Art Design.

1. Inside facing out
When applying lettering to glass, generally the vinyl is cut in reverse and applied to the inside of the glass facing out.
2. Effect of bubbles
Because the vinyl is on the inside, it is extremely obvious if the vinyl lettering forms a bubble between the vinyl and the glass. Why? Because customers will be reading lettering from outside/
3. Wet application
Normally vinyl applied to glass is applied using a wet application technique. This involves wetting both vinyl and glass and squeegeeing out the water from the two leaving a clean application with no bubbles.
4. Waiting time
When using a wet application method you cannot remove the transfer tape (which helps get lettering onto glass) until the vinyl has dried- this can take up to 24 hours.
5. Alignment
When aligning the lettering using a wet application, you need to create guide marks and use a spirit level while the lettering can still be manipulated. Lots of application fluid is the key to achieving this.

6. White is the best colour for window signage. If you don't want white then you need to use a coloured shade not far off white. For example, a pale yellow, pale green etc etc. Using fluro colours is expensive, and using darker colours they get lost against the busy-ness of the backgrounds in shops.
We create hundreds of custom vinyl products for self installation for walls. But applying logos and lettering for your business on glass, we really advise that you get a professional installer and any local signwriting company will be able to help you. Your brand integrity is vital to your business and you need to look professional. Spend the money on installation and focus on your business rather than the hours it will take you to master the art of glass installation.
