Additional Items Needed

Heat Press Method Instructions

1. Cover the press with protective paper.
2. Remove the peel coat film from the hardboard.
3. Place the hardboard face down on the protective sheet and cover with another sheet of paper.
4. Prepress for 20 seconds.
5. Place a protective sheet of paper on top of the hardboard and cover with (at least) a 5 lb. weight and allow to cool fully. After cooling, dry any remaining moisture on the hardboard with protective paper.
6. Product presses face-up with image face down and should be affixed using heat tape or Adhesive Spray. Ensure the transfer does not buckle around the edges. Also, any portion of heat tape touching the image will inhibit image transfer in that area and will communicate an impression of the tape in that area.
7. Place the face-up hardboard (as it remains covered with protective paper).
8. Cover the back of the transfer with protective paper.
9. Press and repeat the cooling procedure as in number 5.

Attempting to peel off the protective film from hardboard using a fingernail or sharp object can cause damage. To safely remove the film with minimal risk, use the tacky side of a recently removed protective film from another tile. Start at one corner and gently drag it across the tile's surface toward the center. If no spare film is available, you can alternatively use your thumb or forefinger to lift the edge of the film.

Should the hardboard warp after transfer and cooling, heat it again with the backside face-up for 20 seconds. Follow the cooling procedure as noted in number (5) above.
