Guardian Gold provides premium “nano-molecule” protection to fine stone, construction stone, concrete, brick masonry and concrete masonry. It’s extremely small molecular structure enables it to rapidly penetrate into the fine pores of engineered concrete, natural stone, masonry and cementicous materials. It provides long lasting, high performance protection against water and oil based contaminants, efflorescence and spalling. Guardian Gold is a water based, clear penetrating, breathable, surface treatment for use on natural stone concrete, brick masonry and concrete masonry. The unique silane treatment penetrates deep into the substrate and chemically bonds with minerals to form a permanently fixed, water repellent molecule. In addition, high performance flouropolymers, oil repellent additives and super wetting agents resist the ingress of motor oil, transmission fluid, diesel and other automotive fluids. These additives also provide unparalleled protection against food and beverage spills such as wine, beer, soft drinks, food grease and ketchup.
