How To Dry Mount Posters

One of the newer methods in setting a poster on a hard backing is by dry mounting it. The method consists of placing a heat-sensitive adhesive between the poster and the board. The heat then liquefies the adhesive through the dry mounting equipment. Once cooled, the adhesive will solidify and poster will now be protected from water and other liquid elements. The steps in successfully dry mounting a poster can be tricky. However, with a step by step guide on how to dry mount posters and some patience, anyone should be able to do it right.

Prepare the poster. The very first thing to do is to prepare the size of the mat board and poster. Measure and cut the mat board to the same dimensions of the poster. Make sure to check the instruction of the dry mounting machine regarding the heating time period dependent on the size of the poster. This will give you a rough estimate on how long it will take to heat the adhesive to mount the poster.

Ready the equipment. Once the poster and the mat board is the right size, plug in the dry mount machine and set it to about 175 degrees. Close, but don’t lock, the arm of the dry mount machine. This will heat up the arm while you are readying the mounting tissue or adhesive. It should heat up for about 20 minutes.

Set the tacking iron. Plug it and configure the tacking iron to the medium setting. Make sure that the iron is not touching anything that could melt or catch fire.

Prepare the mounting tissue
. Measure the mounting tissue, which is the adhesive for mounting, to a size a little smaller than the poster. After that, cut the release paper to fit twice the dimensions of the dry mounting press. For the remaining release paper, cut a five by five square inch piece.

Position the poster. Lay the mat board and place the mounting tissue on top of it. On top of the mounting tissue, position the poster. Position the smaller release paper at one of the corners of the poster. At this point, get the tacking iron and iron out that particular corner in slow and small circular motions. The adhesive should liquefy and adhere to the poster and the mat board.

Use the press. Fold the large release paper in half and place it on top of the poster. Insert the whole thing in the press and close the arm. Make sure it is locked this time. Start heating the poster based on the specifications indicated in the instruction manual of the dry mount machine. After the heating process, allow the poster to cool. Once the poster is cool, you will notice that it is mounted and stuck to the mat board making it seem like one continuous board.

That is how easy and efficient dry mounting of posters can be. Make sure to read and understand the instructions before proceeding with the mounting. Any mistake can result in irreparable damage. Remember that dry mounting should not be used for antique or valuable posters as the process is irreversible. This means that once it is dry mounted, it will always be mounted.
