Basic Mounting Method 1: Direct Mounting
In this method the orginal painting is mounted directly to the silicone paper.
1. Cut the silicone paper to the size exactly same as the original painting or slightly smaller.
2. Dampen the painting to relax any wrinkles. Spray the painting lightly and evenly on either front or back.
3. Put 4 layers of denim cloth on the table as mounting surface.
4. Set the iron temperature to 180° F (between silk and wool).
5. Place silicone paper with silicone side up.
6. Place painting(face up) up on the silicone paper.
7. Place newsprint (or previously used silicone release paper) over the painting to protect it.
8. Iron from center out, first in cross and then in X movements to avoid bubbles.Keep the iron moving and do not stop at one place.
9. Apply less pressure in the beginning and gradually increase pressure later. Don't press too hard or set temperature too hot. Small wrinkles can be stretched out easily with hot iron.
10. Turn the painting over and iron on the back of the release paper until completely smooth. The release paper can be left on until ready to be mounted to a backing material. Because of a larger surface the iron cools slightly so you might want to increase the temperature to wool.
Note large paintings need to be done one section at a time. Large painting will require more time. Continue until the painting is completely dry and there are no wrinkles.

Basic Method 2: Mount Directly to a Backing Material.
This method is to transfer the silicon adhesive film to the backing material first, then take the release paper off and mount the painting on it. Here are the steps:
1. Cut the Silicone Release Paper to the same size as the backing board or a little bit smaller (about 1/4" - 1/8") than the board.
2. Place the silicone release paper film side facing down, or mounting board(museum board, foam board, vellum, watercolor paper, rice paper etc. etc).
3. Iron it at 180 degree F or half way between silk and wool.
4. Peel the release paper off and save it for use in step 7.
5. If necessary, trim the extra adhesive film along the board edge with an exacto knife or scissors.
6. Light spay the painting to relax the paper.
7. Lay the artwork face up on the adhesive film and cover it with the release paper from step 4.
7. Now it's ready to iron it on moving from the center out, first in cross and then in the X movements to avoid bubbles. Keep the iron moving and don't stop in one place.
