ABSTRACT:
Diaphanous mildew sealing, coating compositions are disclosed which are comprised of water containing emulsified latex particles which coalesce into a film at room temperature. A mildewcidal agent is included in an amount sufficient to kill mildew contacted by the compositions and a nonvolatile, relatively insoluble alkaline oxide or hydroxide compound is also included in a weight percent range of about 0.006 to about 0.03 times its equivalent weight. These compositions are scrubbed onto mildew infected surfaces so that the mildew colonies are dislodged and entrapped within the coatings which are formed when the compositions dry. The dried coatings containing the dislodged mildew colonies are then painted to provide a decorative surface which better resists mildew formation.
