SurfaPore FX WB is a water-based suspension of functional nanoparticles that, due to their shape, size, and solvent (water), penetrate deeply into building surfaces, up to 20mm (porous stone cladding). After application, the nanoparticles chemically "anchor" to the application surface and additionally form bonds with each other, resulting in the enhancement of the mechanical properties of weathered or "sensitive" surfaces. The inorganic nature of the nanoparticles ensures chemical compatibility and ease of application with building materials. SurfaPore FX does not clog pores but mechanically supports micro-cracks and the "discontinuity" of materials. Thus, the natural appearance, porosity, and breathability of the modified surfaces remain unaffected.
