How long does the antimicrobial treatment last?
Since the cured antimicrobial is nonvolatile, insoluble, and non-leaching, the treatment should last for the life of the treated surface. The life of a treated surface depends on a number of factors, not the least of which is surface preparation. If you treat a dirty or unstable surface, when the dirt comes off or the surface is disturbed, the effectiveness of the antimicrobial will decrease. Abrasive or caustic (pH>10.5) cleaners will also shorten effective life. In our experience, our home/office applicators have seen effectiveness for ten years or more.
