摘要

The subject of the invention is a process for treating a "permeable" architectural material by impregnation, comprising the spraying onto the architectural material to be treated of one or more liquid-phase dispersions of at least one type of photocatalytic compounds based on metal oxide or sulphide and of at least one type of compound for promoting the adhesion of the said photocatalytic compounds to the said architectural material. The invention also relates to the liquid dispersions used and the architectural materials thus treated.
