Applying Filler
Apply pressure to apply a thin layer of metal filler. Carefully coat all edges in gaps with filler.
Then fill gap completely with filler. Apply filler with about 30% excess because the filler will significantly shrink during hardening. A second application of metal filler is not possible due to poor adhesion.
IMPORTANT:
Use a narrow spatula to fill the gaps. Apply the filler in one draw if possible. Danger of formation of pores in gaps!
No restrictions related to the layer thickness.
