Guide to Selecting Granite for Stairs

Granite stairs add elegance and value to any property. Whether indoor or outdoor, granite offers a perfect combination of durability and beauty.

Types of Granite for Stairs

For indoor stairs, polished granite is a popular choice that creates an impressive visual effect. Light colors like River White or Thunder White brighten the space, while dark colors like Ash Black offer a dramatic look.

For outdoor stairs, flamed or brushed finish is essential for safety. These finishes create a non-slip surface that prevents slipping, especially in rain or snow conditions.

Dimensions and Thickness

Standard treads have a thickness of 3 cm for maximum strength. The width should be at least 30 cm for comfortable walking. Risers usually have 2 cm thickness and 15-18 cm height.

Safety and Non-Slip Finishes

Safety is the number one priority for stairs. Flamed finish creates a rough texture by exposing granite to extreme temperatures. This treatment provides excellent grip without compromising the aesthetic appearance of the stone.

Alternatively, anti-slip strips or grooves can be cut directly into the granite surface. These solutions are particularly important for outdoor stairs or high-traffic areas.

Installation and Maintenance

Installing granite stairs requires precision and experience. Each tread must be cut to exact dimensions and mounted on a solid structure. Joints between treads must be properly sealed to prevent water infiltration.

Maintaining granite stairs is simple: regular cleaning with water and neutral soap. For outdoor stairs, apply a protective sealant once a year to maintain the appearance and durability of the stone.
