Description

The present invention relates to a novel finishing trowel.

Conventionally, trowels are often used for finishing the walls of buildings and the like. For example, as a finishing trowel, a trowel plate made of metal or the like is generally known as a trowel plate, and the mainstream shape of the trowel plate is a flat bottom surface. When finishing with a trowel having such a trowel plate, the work is performed by lifting the end of the trowel plate on the moving direction side of the trowel, but in order to obtain a desired finished surface, the angle at which the trowel plate is lifted and the finished surface It is necessary to finish while adjusting the pressure on the trowel, which may greatly affect the skill level of the operator.

On the other hand, various finishing methods using a trowel have been proposed. In addition to the conventional finishing of coating materials such as plaster and diatomaceous earth, in recent years, for example, a coating material in which colored particles of two or more colors are dispersed has been used. A method for forming a pattern surface has also been proposed.

As a method for forming such a pattern surface, for example, in Patent Document 1, after coating a coating material containing colored particles in which a colored paint is sealed in a capsule film, a coating material containing colored particles is pressed with an iron or the like to form a colorful pattern. The technique of forming is disclosed. In this technique, a desired pattern shape can be obtained by optimizing the pressure at the time of pressing a trowel or the like. However, it is difficult to properly fine-tune the load on the trowel, and depending on the skill level of the operator, the effect of pattern formation may not be sufficiently exhibited.
