Fire-Retardant Paint and Coatings
An intumescent coating looks like ordinary paint until it meets heat. Then it swells into a thick insulating char that shields the siding, eaves and trim underneath.
[ 01 ]The problem
Why this layer matters.
Wood siding, open eaves, fascia and decks are where embers and radiant heat find fuel. Replacing them with noncombustible materials can cost a fortune and change the character of a home. A rated intumescent coating protects the original surfaces and can be tinted to any color or applied as a clear coat on natural wood.
[ 02 ]How we install it
Specified by firefighters. Built by craftsmen.
Every install follows the same four steps and ends with documentation for your insurer.
Inspect
We identify combustible surfaces and the areas inspectors and underwriters flag first.
Prepare
Surfaces are cleaned, repaired and primed. Damaged wood is replaced before coating.
Apply
Certified crews apply the system at the rated thickness, with clear coat on wood you want to keep visible.
Document
We record products, ratings and coverage areas for your insurance file.
