Float
A float (also fumble board) is a hand tool for smoothing and rubbing freshly applied plaster or screed . Rubbing gives the plaster (or screed) greater strength and an even surface.
Floating boards are typically about 30 cm long. Larger versions from around 60 cm and up to 250 cm in length are primarily referred to as grape picks .
Application and variants
The cleaner mostly uses floats the size of a smoothing trowel made of wood or plastic . Depending on the intended use, the float can be provided with different surfaces , such as felt , latex , cellular rubber or sponge rubber .
Floating boards with a felt covering are usually made in the dimensions 14 × 28 cm (or even larger) with a centrally attached handle. They are used in particular to produce a particularly smooth plaster surface , the so-called felt plaster . Floating boards covered with sponge rubber, the sponge boards, are also suitable for the same work . Sponge rubber and felt pads are attached to the trowel with various waterproof adhesives such as PU glue.
A so-called fumbling board is a small float with a beveled narrow side that is used for minor repairs to the plaster. The special shape of the edge makes it particularly suitable for working in corners.
Floating boards are also used for modern mineral rubbing plasters and for artificial plasters.
