How to repair tears in paper using Tengu Gummed

Materials needed:

Tengu Gummed tissue roll, non-woven polyester, knife or water pen, conservator’s sponge or small flat brush, blotting paper, bone folder and weight

  1. Lay a sheet of blotting paper over the worktop. On top of the blotting paper, place a sheet of non-woven polyester material (such as Bondina) as an isolation layer.
  2. Place the item to be repaired on top of the two sheets.
  3. Cut the required amount of Tengu Gummed tissue.
  4. Tengu Gummed repair tissue can be cut to shape using a knife or create a feathered edge using a water pen for a more discreet edge to the repair.
  5. Shorten the width of the repair tissue if it is too wide.
  6. Once the repair tissue is cut to size, place it with the adhesive side facing up, onto a sheet of polyester.
  7. To reactivate the pre-coated adhesive on the repair tissue, a small amount of water is required. Dampen a conservation sponge or a small flat brush though ensure against excessive moisture.
  8. Carefully lift the repair tissue with tweezers and place it onto the area to be repaired.
  9. Place a piece of non-woven polyester over the repair and lightly burnish with a bone folder for adhesion.
  10. Carefully lift the polyester and ensure complete adhesion.
  11. Place the polyester then blotting paper over the repair site.
  12. Place a weight onto the blotting paper and leave to dry.
