Sound can be stuck again after breakage

The material clay generally sticks well. Often a repair resembles a little piece of puzzle work. The more precisely the break points are placed on each other, the more invisible the damage becomes. Powerful two-component adhesives not only bond the fragments to each other, but also fill any cavities that have formed.

Save the material and do not change the sound object

Sound can break and splinters often. As the first and most important immediate measure, the fragments should be secured. If a glaze is present and has been damaged, it is also recommended to secure small "glaze flakes". The more complete the loosened material is collected, the more successful the gluing can lead to the restoration of the original look.

If technically possible, clay objects in use, such as terracotta pots, should be glued without "planting" them. Any change in state alters the tensions and has the potential to increase fractures and cracks.

For porcelain products also superglue are suitable if the fracture surfaces and places consist of glazed pieces. Whenever "naked" clay meets one another, a two-part adhesive should be chosen as superglue penetrates too much into the porous clay and loses the bonding effect.

How to paste sound

  • Sound object and fragments
  • Two-component adhesive
  • duct tape
  • Brush with plastic bristles (baking brush)
  • cutter
  • tweezers

1. Clean

All surfaces that will come into contact when gluing must free you from dust and grease. Brush the surfaces with a brush. Be careful not to touch the fractured surfaces with your fingers and "grease" them. For small fragments, tweezers can help with holding

2. Customize

Find the position of the fragments on the clay object and develop a sequence plan. If fragments overlap, you must first place the lower ones and then layer by layer in order.

3. Activate adhesive

Stir the two-component adhesive according to the manufacturer's instructions. The processing time is usually only a few minutes, so you should edit the fracture surfaces on both sides immediately after activation.

4. Apply glue

Coat the adhesive in a thin layer of film on both fractured surfaces. If the clay is very absorbent, increase the dose.

5. Let it dry

The adhesive must be allowed to dry for a few minutes according to the manufacturer's instructions.

6. Fit fragments

Then press the embalmed areas together by fitting them together. For several fragments, follow your previously designed sequence plan.

7. Fix

Fix the stuck fragments with tape strips. Be careful not to use too much adhesive tape. Masking tape is well suited.

8. Let it dry

Allow the glued joints to dry for at least 48 hours with fixation. Finally, remove the tape.

9. Remove burrs

Use a cutter to cut off the burrs, if necessary, on the glue joints.

Tips & Tricks

If you glued glazed clay, you should seal the adhesive joints with transparent water-based paint to restore the waterproofness.
