A product and process for imparting stain and water repellancy to fabric, wherein a heat-curable resin which has the property of imparting stain and water repellancy to fabric when applied in proper amount to the fabric and cured, and that can be dispensed as an aerosol, is mixed in suitable proportion with a diluent and placed in an aerosol container along with a suitable propellant. The composition is then sprayed onto the fabric until the fabric is wet. The concentration of the resin in the composition is such that when the fabric is wet with the composition, an appropriate amount of the resin is on the fabric to impart stain and water repellancy to it when the fabric is dried and the resin cured. Curing of the resin can be accomplished by ironing the fabric, or by drying the fabric in a clothes dryer at normal settings. A preferred resin is FS-7520, an aqueous-based concentrated fluoropolymer system, manufactured by Fiber-Shield Industries, Inc. of Yaphank, N.Y., diluted with water to obtain a concentration of 3%-4% solids in the composition used in the invention.
