How does Capstone's Clean Surface Technology work?

Capstone's Clean Surface Program is a proactive surface cleaning and treatment program (with the Aegis Microbe Shield(R) Technology).  Our process involves a detailed pre-clean to remove any biofilm build-up and and then application of our surface antimicrobial treatment for a long term, durable defense against most all microbes.  The technology has been in use since it was invented in the 1970s showing it to be a globally proven antimicrobial formula that forms a colorless, odorless, and positively charged polymer that permanently bonds to any treated surface.  Think of it as a layer of electrically charged microscopic "spears". When a microorganism comes in contact with the treated surface (the electrically charged "spears"), the spear punctures the cell membrane electrocuting and killing the microbe.  The antimicrobial remains bonded to the treated surface, so the antimicrobial doesn’t lose strength and the spear is ready for the next cell to contact it.  Normal cleaning of treated surfaces is all that is necessary to maintain the full effectiveness of the now modified antimicrobially treated surface. 

What does the Capstone Clean Surface Treatment help protect against?

Our Surface Treatment has been independently tested to be effective against:

  • Pathogens such as MRSA

  • Most Molds and Fungi and Mildew

  • Most Bacteria

  • Many Viruses

  • Odors caused by microorganisms

  • Algae

What is the purpose of the silane portion of the molecule?

Silanes are extremely efficient bonding agents, which can be coupled to other molecules and then used to permanently bond those molecules to a target surface.  This process modifies surface properties of building materials and transforms them to a material that will not support microbial growth.  In other words, it is the glue that holds the spear to the surface. 

What is the difference between the Capstone Clean Surface technology and other antimicrobials on the market?

Conventional products penetrate living cells and kill by way of poisoning the organism. They are designed to act quickly and dissipate quickly to avoid adverse effects to humans and animals due to their toxic ingredients. Most commercial antimicrobials used for treating building surfaces do a great job of getting a quick kill on bacteria and fungi, although most have a limited spectrum of effectiveness. The Capstone Clean Surface technology takes a totally unique approach. It provides an effective initial microbial kill when applied - like the conventional methods - but it also provides long-term resistance to microbes on treated surfaces...basically, for the life of that surface with routine cleaning. The surface itself is modified to make it antimicrobially active for the normal life of the substrate onto which it is applied.

Is there a test method to determine if the Capstone Clean Surface Technology was effectively applied?

The Capstone Clean Surface technology has an active ingredient that, in most cases, can be easily detected. Also, there are a variety of pre-and post treatment microbial tests that readily verify its efficacy. 

Is Capstone's Clean Surface Technology permeable to moisture?

Yes, moisture that is in or on the treated material or surface passes through the treatment. After curing, the treatment is somewhat hydrophobic (water repellent), but it should not be considered a replacement for commercial water repellents.

Does Capstone's Clean Surface Technology off-gas during or after application (does it have significant odors)?

No, it does not volatilize, dissipate, or leach onto other surfaces or into the environment.  Curing takes about an hour and with normal ventilation, there is no detectable odor.   Its chemistry polymerizes where it is applied and forms a permanent bond that lasts for the life of the treated surface. Normal cleaning should not remove the treatment, although it can be abraded away if the surface comes into contact with a gritty compound.

Is there re-growth after treatment?

The Capstone Clean Surface Technology lasts a long time.  Because of its unique chemistry, it provides a durable long-term protection against regrowth and future contamination - usually for the life of the treated surface if that surface remains clean.  Re-growth can occur after a long period of time if the treated surface is inadequately maintained or cleaned.  

How long does the treatment last?

Since the cured antimicrobial is non-volatile, insoluble, and non- leaching, the treatment should last for the life of the treated surface. Normal cleaning should not remove the treatment, although it can be abraded away if the surface comes into contact with a gritty compound that mars or damages and removes the surface.  Also, if a surface is painted over, re-application will be required. Abrasive or caustic (pH 12.0) cleaners will also shorten effective life.  For extreme situations where routine cleaning is not possible, and where moisture and bio-film build-up are challenges, re-application is recommended at periodic intervals from every 3 months to annually, depending on the scenario.  A Capstone representative can advise accordingly based upon review of each unique situation. 

What preparation is necessary prior to applying the treatment?

Surfaces should be thoroughly cleaned with Capstone Clean Surface Technology detergents prior to application.  

How should a contaminated surface be treated?

There are many toxigenic microbes. In order to ensure best results the surface to be protected should be cleaned. Severe contamination with hazardous organisms may require cleaning protocols similar to those for asbestos removal. For normal contamination, solid surfaces should be thoroughly cleaned before treatment. Soft surfaces such as carpets and upholstery should be well vacuumed or professionally cleaned. Insulation can be cleaned and treated if only superficial growth on the surface is present. Insulation that has heavy growth or is damp should be removed and replaced.

How does the Capstone Clean Surface Treatment get applied?

CapStone Clean Air technicians are trained and understand state-of-the-art application techniques that address your specific project's scope of work following established protocols. Large areas most generally will require the use of the electrostatic process, which utilizes spray wands with nozzles that impart an electrostatic charge to provide a very uniform and thorough coverage of the targeted surface.
