| Q1 : What is the difference between wet mount and dry mount? Wet mounting requires the image to be mounted on a foam board that is often the same size as the poster, or is centered within the poster board using either a glue stick or spray adhesive.
 
Dry mounting is a method of setting the image on a hard backing through the use of a heat-sensitive adhesive material.
 
A wet mount is freshly prepared, while a dry mount is pre-prepared and sealed. 
 Air bubbles can be trapped in a wet mount but not in a dry mount
 Wet mounts are inexpensive to make and don't last as long | link |
