It was investigated whether and how the storage time of a fireproof salt preparation affects the effectiveness of fire retardance. The impact of long-term heating of the treated wood on the effectiveness was also determined. Statistical methods were used to determine the significance of changes related to the age of the preparation and the effect of heating of treated wood on flame retardant effectiveness. A commercial fire retardant was used for the tests, with three different storage times and in five concentrations. The flammability tests were performed using the Mini Fire Tube method. It was concluded that the storage time of the preparation does not significantly affect the effectiveness values.
