Abstract: A power trowel blade that is made of non-rusting solid component material for use with a power trowel apparatus. The trowel blade include a mounting surface and an oppositely facing finishing surface. The finishing surface is flush and free of voids or protrusions. The flush finishing surface prevents surface material being collected as the trowel blade is used to finish surfaces to a hard finish.

Abstract: The present invention relates to a method for laying tiles (2) on a laying substrate, in which, initially, tile adhesive (8) is applied to the laying substrate and the tiles (2) are subsequently laid in the tile adhesive (8), characterized in that, before applying the tile adhesive (8) to the laying surface, leveling strips (5) of the same height are affixed so that the top faces of the leveling strips (5) lie in a common reference plane, and in that the tile adhesive (8) is applied between the leveling strips (5) with some protrusion which is then, using a screeding board (9) guided along the top faces of the leveling strips (5), removed down to the level of the reference plane, generating a flat tile adhesive layer (11).

Abstract: Surface-formation equipment includes a blade including a beam; and an attachment structure having a proximal end connected to the blade and a distal end configured to be attached to a mobile unit. The surface-formation equipment may also include a blade including a beam; and at least one lateral wing pivot-connected to one end of the main section, the at least one lateral wing being able to be configured in an unfolded configuration and at least one folded position. The surface-formation equipment may include a cutting edge secured to the beam near the lower surface.
