Abstract

Abstract A masking system including a water soluble liquid masking composition to be spray-applied in film form to a limited area of a configured surface having a contiguous area to be coated for suppressing dust in the limited area and to prevent dust from migrating to and marring the quality of the coating, comprising an aliphatic polyhydroxy liquid carrier in which are dispersed a thickener and surfactant, the viscosity of the film being such that it remains substantially continuous on a vertical panel.

Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 152 words
A masking system including a water soluble liquid masking composition to be spray-applied in film form to a limited area of a configured surface having a contiguous area to be coated, the masking composition suppressing dust in the limited area to prevent such dust from migrating to and marring the quality of the coating in the contiguous area, said composition comprising about 10 to about 30 weight percent glycerol as an aliphatic polyhydroxy liquid carrier in which are dispersed about 0.05 to about 5 weight percent surfactant and about 0.05 to about 5 weight percent xanthan gum as a thickner, balance substantially water, the surfactant aiding wetting and spreading of the masking liquid when applied and effective to produce sudsing of the film for easy removal by a water wash after the coating has dried, and the viscosity of the film being such that it remains substantially continuous on a vertical panel.
