ABSTRACT:
A latex aerosol paint composition having a total solids content of less than 40%, a viscosity of from 10 to 60 seconds measured on the No. 4 Ford cup, a pigment content of from 2 to 15%, is dispensed from an aerosol container having a mechanical break-up valve utilizing nitrogen or air as the propellant. The ratio by volume of the compressed nitrogen or air at a pressure of 100 psi at 70.degree. F to the volume of the paint composition is from 60:40 to 50:50. In the preferred embodiment, the volume ratio of the nitrogen to the paint formulation is 60:40. The solids content may be as low as 30%, and the viscosity of the paint formulation is from 15 to 30 seconds on the No. 4 Ford cup. It is preferred that the average particle size range of the pigment be from 0.2 to 0.3 microns.
