Cobble™ Impregnator (NS) is a low-VOC, water-based, clear, breathable sealer for protecting natural stone surfaces. Providing a natural look with no sheen, Cobble Impregnator is ideal for providing protection without changing the surface’s appearance. The breathable formula allows it to be applied in situations where film-forming sealers would not work, including on surfaces where moisture does not readily dissipate, such as stone installed over a concrete slab. Each gallon of Cobble Impregnator (NS) will cover approximately 200 square feet per coat; the 5-gallon container of Cobble Impregnator (NS) will cover approximately 1,000 square feet. Coverage will depend on surface porosity, joint width, and method of application. Natural Stone may require less material than other substrates.Over Previously Sealed: Film-forming sealers will need to be stripped before application. Cobble Impregnator (NS) may be applied over non-film-forming sealers, provided the prior application is sufficiently worn away. Try before you apply — Shop samples now.
