Cover-A-Stitch Thermoseal is a heat-activated permanent waterproofing film that maintains the integrity of waterproof or water-repellent fabrics when you embroider or sew on them. Just apply Cover-A-Stitch Thermoseal to the back of your embroidery and water and moisture will not penetrate the fabric through the tiny embroidery needle punctures.

Rain gear, outdoor jackets, functional clothing can be embroidered and everybody stays dry-use on work clothes e.g. for road construction, gardening and for all outdoor jobs.

Directions For Use:
  • Remove stabilizer after embroidery process from waterproof or water-resistant fabric.
  • Cut a piece of Cover-A-Stitch Thermoseal slightly larger than the embroidery design.
  • Place Cover-A-Stitch Thermoseal onto wrong side of embroidered fabric, adhesive side facing down (the adhesive coating faces out on roll, slightly glossy look).
  • Seal with heat press. Temperature 266°F-300°F (130°C -150°C) with medium pressure for 10-15 sec.
  • For maximum adhesion, allow Cover-A-Stitch Thermoseal to set for 48 hours after pressing, before administering any washing tests.

TIP: Testing is necessary to ensure the adhesiveness of the film. Just press a small piece of Cover-A-Stitch‚ Thermoseal to the back of the fabric before embroidering. If the film sticks to the fabric, start with the described process.
