“Up, up and away…” Sorry — wrong kind of float. Nor is it the summer treat made from mixing soda and ice cream. In the design world, the word float is both a noun and a verb used to describe the process of smoothing out a wall, ceiling or floor with a plaster or cement, creating an even surface suitable as a substrate for paint, wallcovering, flooring material, etc. If a surface is rough, uneven, pockmarked, or generally damaged, then using float to float that surface (see how it can be used both ways?) is critical to make the application of the material successful.
