What makes PHOS-CHEK so effective against wildfires?

Wildfires move quickly, as wind and dry conditions fuel the flames, and flying embers quickly start new fires where they land. But as powerful and unpredictable as wildfires can be, you still have a fighting chance to prevent fire from spreading to your property. 

Proven to stop the spread of wildfires

PHOS-CHEK® is a non-colored long-lasting fire retardant. The US Forest Service has used PHOS-CHEK to stop the spread of wildfires for 60 years. PHOS-CHEK ground-applied retardant has a similar product formulation to the solution you’ve seen dropped from planes during active wildfires, but was developed with greater durability and adherence to provide extended protection. And now PHOS-CHEK is available for home application.

The most important step you'll take this season

It is recommended that an Authorized Service Provider apply PHOS-CHEK to your property, but it can be applied easily by homeowners. Just mix and spray around the perimeter of your home, outbuildings and other areas of at-risk fuels. One application can help protect your home and property for months, until a significant rain event occurs. 

PHOS-CHEK works naturally by changing the molecular structure of organic materials like wood and vegetation so they’re no longer combustible. PHOS-CHEK is safe for people and pets, and it is environmentally responsible when used as directed.
