Frequently Asked Questions
What should I spray with MFB-31?
The biggest wildfire threat comes from dry fuels. MFB-31 can be sprayed on houses, shake roofs, decks, doors, eaves, fences, outbuildings, sheds, dog houses, dry brush, shrubbery, and trees—anything that wind-driven embers could ignite and support fire advance.
When it comes to decks, even leaves that get blown and trapped under the deck pose a threat. The only way to remove this threat is to close the deck elevation, so wind driven hot embers cannot gain entry to ignite and burn the deck, especially of the deck is attached to the home.
Do fences sprayed with MFB-31 provide a fire break?
Staining or painting a fence helps create a fire break effect. For greater protection, spray both sides of your fence with MFB-31 and install a horizontal base board, so fire and embers can not get under the fence.
How much MFB-31 do I need to defend against fire ember ignition?
MFB-31(LC), our Liquid Concentrate, comes in 1-gallon containers that will make 5 gallons of fire inhibitor. That 5 gallons of fire inhibitor will coat 500-700 square feet of area on solid wood surfaces, such as fences and decking. When spraying to coat dry brush or trees, the degree of dryness affects how much liquid should be used when spraying.
Our Applicators are trained to spray MFB-31 using approved backpack spray cannons, which dispense the proper amount of inhibitor on dry vegetation and trees.
How often should I spray MFB-31?
As a general rule the drier the fuel, the more often it should be sprayed with MFB-31. Fences, decks, patio covers, and wood shake roofs should be sprayed a minimum of twice during the hot summer months or again after a rain. Your first application should be near the start of the warm weather season. Our Applicators have been trained to assess the risks of each individual property and make a recommendation for the frequency of spraying.
If a wildfire is approaching, and you are being told to prepare for a possible evacuation, you can respray. Just make sure to evacuate when you are told it’s time.
What is Mighty Fire Breaker’s No Short Cut wildfire defense program?
We believe you shouldn’t have to settle for “just-in-time” private firefighters. Our approach is to harden (prepare) structures before an event occurs, based on an assessment your property's unique risks—with chemistry that is safe to use around humans, animals and the environment. Recent research indicates that two out of every three homes destroyed during wildfire events was the result, directly or indirectly, of wind-driven hot embers. These embers are capable of igniting and burning your home in several ways. Our No Short Cut recommendations for lowering your risk of loss include:
- Creating fire breaks by removing combustibles from around the home, including easy
- •Blocking embers by retrofitting roof, gable end, soffit, and crawl space vents with wildfire-resistant vents, a key step in our No Short Cut program.
- Creating a perimeter around your home with our rooftop, selfpowered Locked-N-Loaded sprinkler system equipped with patent protected fire inhibitor, our secondary line of defense that is put into action by the property owner when asked to evacuate.
- Spraying our fire inhibitor in areas around the home that pose the greatest risk—twice a season, during hot months—to help reduce the risk posed by dry vegetation, patio covers, decks, garden bark, and fences.
