Gunnison Basalt is an excellent choice for interior and exterior applications. It is a durable, hard stone which is resistant to freeze-thaw cycles. Its medium dark gray color and small markings are relatively consistent. Architects specify this natural basalt for interior flooring, exterior paving stone, stair treads, fireplace surrounds and stone wall cladding. Gunnison Basalt is available in honed, cascade and polished finishes.
Medium dark gray. Relatively consistent in shade. Small, natural markings occur.
Gunnison will hold its basic color even after many years of exterior use.
Hard, durable, resistant to freeze-thaw cycles. Naturally occurring, small holes are visible. These holes can be filled for interior applications. No detrimental effects on the environment.
Depending on the application, an impregnating sealer may be required. Clean with a neutral stone soap – never with chemicals. Contact us for information regarding the use of sealers, impregnators, oiling, cleaning, etc.
