A paint b anic materials painted on eing no stronger than its foundation, attention must be paid to proper cleanin of the concrete. The effect of moisture in pushing o ff bodily many surface films, partly by preferential wetting and partly by efflorescent crystal pressure is pointed out, The caustic character of moisture in the concrete endangers many organic films. The ability of a film to breathe or transmit water vapor is often an import- ant factor in securing continuin are iven for the application o h f adhesion.
