A method of covering stress cracks in drywall, plaster or the like which comprises the step of spraying an aerosol composition which air dries to a film which has an elasticity of at least 100 percent elongation. The aerosol composition comprises a propellant, a solvent, and a concentrate including film-forming copolymers and resins. To prevent any apparent reoccurrence of the crack, the aerosol composition is pigmented. The pigmentation of the aerosol composition is such that, when the film is stretched, the outline of any reappearing stress crack will not become noticeably visible either through the film or because of marked differences between the coloration of the stretched film and of any topcoat of paint on adjacent surfaces.
