Picture Dry Mounting is a permanent mounting process where the art is glued to a mounting board, using heat and pressure. The mounting board is usually a foam core board, but other boards can be used depending on the circumstances of how the art will be used. A tissue type adhesive is placed between the art and the mounting board. This combination is then inserted into a vacuum press and heated up to activate the adhesive while the press applies pressure. If a piece of art is to be conservation framed then dry mounting cannot be used, since it would adversely affect the value of the art. Dry mounting is used when the aesthetic appearance of the art warrants it to be flat. An inexpensive replaceable movie poster, art poster or music poster would be good examples of items that would be dry mounted.
