A composition that can be used as an additive to paints, adhesives and resins to provide a prolonged effectiveness to kill microorganisms exposed to the coating is disclosed. The biocidal coating is comprised of a calcium hydroxide particulate that is within the matrix forming material (e.g. paint, adhesive, resin, etc.). The calcium hydroxide is hygroscopic and attracts waters at a surface of the biocidal coating to limit conversion of the calcium hydroxide particulate at the surface to calcium carbonate in order to maintain a high alkalinity of the biocidal coating.
