A flame-retardant composition has a plurality of particles with a plurality of porosities formed therein, a flame retardant gas occupying the porosities, and a matrix material in which said particles are dispersed. It provides a sealant applied to at least a portion of the particles, wherein the sealant substantially prevents the gas from escaping the porosities. The matrix is a flame-retardant composition adapted to be applied to various surfaces. At least one of the matrix and the particles is formed of a material that will break down and release the gas in the presence of water. At least one of the matrix and the particles is formed of a material that will break down and release the gas in the presence of flame. The sealant may be a polymer material. This solves the problem of applying flame-retardant qualities to various surfaces.
