ABSTRACT:
A method for drying a surface comprises supporting a fabric cover above the surface, and holding side edges of the fabric cover against the surface such that an air channel is formed between the fabric cover and the surface. The air channel has an inlet end and a discharge end, and a pressurized warm air stream having a relative humidity less than an ambient relative humidity is directed into the inlet end of the air channel such that the warm air stream moves through the air channel to the discharge end and out to the atmosphere. An apparatus for practicing the invention provides a plenum along the inlet end with plenum outlets to discharge the warm air stream, and cover supports extending out from the plenum to support the cover above the surface. A fabric tube plenum and cover supports provide versatility and portability.
