Abstract: Compositions and methods for treating porous substrates are disclosed. An example of such a composition includes sodium acetate, which forms hygroscopic crystals that change size as they absorb and desorb water. The crystals partially seal the pores to reduce water permeability and effectively scrub the pores as the substrate experiences wet and dry cycles.
