Over centuries , s tone has proven to be a n excellent building material though it can be counted as a porous one . These pores can accumulate dirt , ruining aesthetic impression. Stone is water - absorbent and it's crucial for long - lasting performance i n colder climate zones . W hen water penetrates stone and freezes overnight, ice crystals expand and bricks, concrete, and limestone may cr ack. When stone's integrity and safety are compromised, nature takes its course, and plants and moss fight their way through solid rock. To prolong the stone's lifespan and unique look, good care, and regular maintenance are required. Our nanoceramic coati ng s are a viable and permanent solution to these issues. Ceramic Pro nano - components simply fill in the pores, creating a water - repellent protective layer on the stone's surface. Its thermodynamic qualities won't change as the treated stone still "breathes " . With our coatings, cleaning and maintenance time are minimized, and this is what makes a real difference.
