Finding the Right Antimicrobial Paint
Finding the Right Antimicrobial Paint
Choosing from different antimicrobial surface technologies can be challenging. Follow this easy 3-step guide on what to look for when selecting an antimicrobial paint.
What to Look For

EPA Registration

Viral Efficacy
Viral Efficacy
Look for claims against “Feline Calicivirus”, Norovirus or another non-enveloped virus. Some antimicrobial ingredients only work against easier-to-kill germs, so it's important to check the fine print to be certain the product is effective against hard-to-kill germs like non-enveloped viruses.
