This float is extruded from very hard, durable, lightweight magnesium that is pre-shaped across the length and width of the blade. The front and back of blade won’t dig in, while the sides glide over surface. This tool assists the user in preparing the surface for troweling. Magnesium floats produce a smoother finish than wood. The DuraSoft® handle provides a soft feel, reduces fatigue and offers excellent durability.
