The Ecolife treatment does not impart fire retardancy properties to decking. Unfortunately there isn’t a treatment on the market for both durability and fire retardancy.
A fire retardant coating will likely wear off over time because it is not pressure impregnated. In addition, building codes do not recognize sprayed-on or brushed-on coatings as code approved fire retardants for wood products; they only recognize formulations that are vacuum/pressure impregnated products.
Most pressure treated fire retardants are for interior use only, i.e. our D-Blaze fire retardant treated wood product. However, there are some exterior fire retardants available but they don’t increase the weathering, durability, or insect/fungal protection of wood so they are usually only used on naturally durable species of decking like Redwood and Western Red Cedar. The availability is somewhat limited so you would have to check with your local retailer on availability.
