Abstract

Protection of stone materials, marble, bricks, concrete etc. against decay caused by atmospheric agents and pollutants comprises application of a protective agent comprising (1) fine powdered PTFE or tetrafluoroethylene copolymer copolymer contg. upto 12 mol% perfluorinated comonomers; (2) perfluoropolyether not bearing functional gps.; and/or (3) (per)fluoropolyether having one or both chain ends constituted by a functional gp. capable of forming a chemical and/or physical bond to the material to be protected, or prod. of polycondensation o ethylenic polymsn. of the functionalised (per)fluoropolyether.
