Can the treatment be renewed? – There is no need for this as the treatment lasts for the lifetime of the carpet. Is it possible to apply the protection retroactively on existing carpet installations? –There might be but this will not be a permanent treatment. By applying during the production of the carpet, we are able to control the amount and permanently bond the product to the carpet. –If you treat a dirty or unstable surface, some of the anti-microbial shield will be removed when the dirt comes off or the surface is disturbed. Does the biocide use a heavy metal? – No. The Hammer anti-microbial treatment does NOT contain any heavy metals. Tin, arsenic, silver and copper are often used in other anti-microbials but not used by Hammer. Does the Hammer anti-microbial shield give off gasses after application? – No. The treatment does not volatilize, dissipate, or leach onto other surfaces or into the environment. The chemistry polymerizes where it is applied and forms a permanent bond that typically lasts for the life of the treated surface. Normal cleaning should not remove the treatment although it can be abraded away. Is there a test method to determine if the Hammer anti-microbial treatment is present? –Yes. The Hammer anti-microbial treatment is based on an active ingredient that, in most cases, can be easily detected. A simple method of detection is available to demonstrate the presence or absence of the treatment. Bromophenol Blue (BPB) stain testing clearly shows the presence of the treatment in a matter of minutes. Why is the Hammer anti-microbial treatment so durable? –Because of the exceptional chemical bond (a covalent bond), the bonded polymer is neither soluble nor volatile. The unique bond results in the anti-microbial polymer becoming an integral part of the substrate.
