Bacteria and Germs Resistant Paint

Covid 19 has everyone panicking in the spring of 2020.  But bacteria and germ resistant paints have been around for a few years.  

So what is a germ resistant paint? 

Sherwin William Paint Shield Shield® is the first EPA-registered microbicidal paint that kills greater than 99.9% of Staph (Staphylococcus aureus), MRSA (Methicillin-resistant Staphylococcus aureus), E. coli (Escherichia coli), VRE (Vancomycin-resistant Enterococcus faecalis) and Enterobacter aerogenes within two hours of exposure on painted surfaces. It continues to kill 90% of these bacteria even after repeated contamination on painted surfaces. The effectiveness lasts for up to four years as long as the integrity of the surface is maintained.en after repeated contamination on painted surfaces.

There are many places we would suggest this type of paint be applied.

  • Schools
  • Daycares
  • Hospital
  • Clinics
  • Health Offices
  • Laboratories
  • Nursing Homes
  • Medical Waiting Rooms
  • Dental Facilities

All of these area can be breeding grounds for germs and bacteria. So it naturally makes sense to use a paint product that can minimize and help prevent the spread of these harmful microbes.

This Paint Affects Germs

Obviously cleaning is still necessary, however over time these paints can eradicate 99% of the germs like the following:

COLIi – Escherichia Coli

Enterobacter Aerogenes

MRSA – Methicillin-Resitant Staphylococcus Aureus

STAPH – Staphylococcus Aureus

VRE – Vancomycin-resistant Enterococcus Faecalis

Some precautions and extra steps need to be taken during the installation of this paint.  It produces some health problems if handled incorrectly. Alkyl dimethy benzyl ammonium chloride requires eye, skin and protective clothing during installation.  Personally I require my employees to use respirators when we started installing PEG Polyethylene glycol when I learned of the first protection it had against bacteria.  It suddenly made sense that if it kills bacteria on contact it can’t be good at any level on a person or painter. PPE is required and it’s important to have a plan of attack and a good window for installation.

While we install this paint on a limited basis, it should only be installed in an area where there is an extra layer of defense needed.  Some researchers suggest that the more we subject bacteria to antimicrobial chemicals the more they will mount a defense. This suggests that it might be possible that bacteria become more resistant with more exposure.  The spore-forming bacteria are capable of surviving and and possibly mutating. So in general terms, I suggest limited use of the paint, but where appropriate.
