AbstractEmulsion paints have been widely promoted on the basis of their ability to "breathe" or transmit water vapour. In Canada, their chief use has been on concrete structures. However, in localities where stucco is used, there may be a desire to apply emulsion paints for decorative purposes. Concern has been expressed that their use might lead to spalling of the rendering surface because of repeated freezing and thawing cycles. The work reported here shows that application of emulsion paints to old rendering is satisfactory. If applied to fresh rendering, damage from frost action may occur if cement is not included in the formula. Emulsion paints cannot be expected to waterproof masonry walls that were improperly constructed in the first place.
