A colourless, odourless, non-toxic, non-corrosive liquid that can be sprayed onto any type of materials which will absorb the chemicals including both natural and mixed fibres such as cotton/polyester and pure synthetics such as nylon. It will also treat wood and foam rubber. Extremely effective due to the chemicals forming a carbonised shield in the presence of heat. Always pre-test a sample before treatment. Application lasts for the useful life of material treated. 1 litre covers 100-120 square feet [9-11m2 per litre].
