Wet vs. Dry: When to Get Wet (vinyl graphics)
Posted by Wendi Miller on Mon, Feb 06, 2012 @ 02:08 PM
There are two methods to apply vinyl graphics, wet and dry. The difference is pretty self explanatory: dry is without any type of liquid aid, and wet is when a liquid is used to ease the application process. There are special products sold just for this purpose, like RapidTac, but plain soapy water can also be used.
When applying a graphic using the wet method the liquid creates a barrier between the vinyl and the substrate, which lessens the chances of bubbles and makes the application easier. It does, however, create quite a mess and requires clean up. There is also a drying period after the graphic is applied, so the vinyl should be left alone until dry and properly set. Most sign shops and installers apply graphics dry the majority of the time. It’s quicker, less messy and when the graphics are applied it’s done, no dry time. It does, however, take a more skilled hand to apply a graphic dry and have it be smooth and bubble free.
So when should graphics be applied wet? The only time I apply vinyl wet is when I’m applying etched vinyl to glass. Glass is extremely smooth and non porous, so when the vinyl touches it sticks. The liquid makes that barrier between the two materials and allows the vinyl to go on smooth and bubble free.
