<p>The present invention prolongs the biocidal activity of a hydrated lime coating using a binder having the film properties of a carbon dioxide barrier but not having the film properties of a water barrier. The binder can be used either as a component of the hydrated lime coating, itself, or in a separate protective film for a hydrated lime coating. The coating can be based on either an aqueous or an organic solvent.</p> |
