Description

[0001] SPACULA FOR FINISHING INFILLING [0002]

The present invention relates to a finishing spatula for finishing a filling material so as to form a convex shape in consideration of shrinkage due to self-hardening of the filling material to form the filling material flat after the finishing work of the filling material.

When a structure such as a tile or a coating material is attached to a wall surface, a space may be formed between the structures. When the space is exposed to the outside, there is a problem that the structure is worn or broken, or air or foreign substances are introduced into the space and noise is generated. To prevent this, a filler is applied to the space between the structures.

If the filler is applied to make the space between the structures very large, the applied filler may be subjected to a finishing operation. The finishing operation is to apply the filler between the structures, flatten the end of the filler exposed to the outside, and align the height with the adjacent structure.
