ADD-A-SHIELD starts to works as it dries(3-5 minutes) and the bacteria comes into contacts with the treated surface. ADD-A-SHIELD then works continuously to maintain a consistently lower bio-burden than would be expected on a surface without ADD-A-SHIELD protection.
ADD-A-SHIELD technology has undergone extensive independent laboratory testing and has a long history of safe use. It is registered with the EPA for all applications listed on the label.
The label for ADD-A-SHIELD is the best indicator of some of the possible uses an EPA registered product must be used and sold according to its APPROVAL LABEL USES in the case of ADD-A-SHIELD; this is a plus to be used against other products.
