1. A surface spatula, designed as a hand tool for making smooth surfaces in a construction industry comprising a frame and a working part embedded in the frame, in which the frame of the tool has a shaped handgrip and a tool holder, characterized in that it has the frame provided on the surfaces of the gripping parts with a soft, convex cover (3) made of thermoplastic plastic, wherein the cover (3) is integrally connected to a substrate on parts of outer surfaces of the spatial structure of the frame shaped in the form of a longitudinal profile (1), made of a hard structural plastic, selected from the group of plastomers consisting of polyvinyl chloride (PVC) and polypropylene, and whose spatial structure is a closed body, internally ribbed, wherein the handgrip has the same outline along an entire length of the handgrip, wherein the cover (3), also made in the form of surface elements (27), is present on the outer surfaces of the handgrip (2) and a connector (5), wherein elements of the spatial structure of the profile (1), present in the frame, in parts including the handgrip (2) and the connector (5), wherein the frontal view of the outline of the profile (1) of the frame the hand grip (2), located in an upper part of the frame, has the shape of an outline (15) similar to an ellipse and which in a lower part with gentle, concave arcs is connected with the outline of the shape of the connector (5), narrow in relation to the shape of the tool holder (4) and located in the lower part of the frame, wherein the connector (5) has in the middle of its heights a neck constriction, wherein the connector (5) is positioned asymmetrically in relation to the hand grip (2), wherein on one side of the connector (5), to its lower part, there is a spatial lateral structure of the frame attached in the form of an extended arm (8) and a support (7) is also attached on the same side of the connector (5), located below the arm (8), wherein in the frame portion between the arm (8) and the support (7) there is a tool seat (6) with a two-part, open space of a tool slot (9), consisting of a wedge part (10) and a rectangular part (11), wherein in the tool slot (9) is fixed and fastened, detachably, a seating part of the known working element for direct puttying, thin plate (16), where the seating part of the thin plate (16) is fixed longitudinally in the frame by plug plates (26), which are seated and close, detachably, a face of a spatial structure of the profile (1) of the frame, wherein the plug plate (26) has a shape corresponding to the contour of the face of the spatial structure of the profile (1) of the frame, and on the outside, the plug plate (26) has a flat surface, and on the inside, the plug plate (26) is provided with a stiffening protrusion (30), with retaining protrusions (31) and clamping protrusions (32, 33).
