Description

Dunhouse Buff Sandstone is a fine-grained, non-calcareous, slightly micaceous sandstone with a generally buff coloration. Geologically, it is classified as a meso-microcrystalline arenite. Extracted from the heart of Eesdale, near Darlington, Durham, Dunhouse Buff Sandstone has gained popularity for its blonde coloring, fine grain, and consistency. These characteristics make it ideal for carving and a suitable choice for restoration and new construction projects in cities such as Edinburgh, Glasgow, and Newcastle.

The quarry from which Dunhouse Buff Sandstone is extracted was initially opened to build Bowes Museum in Barnard Castle, completed in 1892. The enduring quality of the museum's detail, still evident today, serves as a testament to the stone's durability.

Can United Kingdom's Dunhouse Buff Sandstone be used exterior applications in very dusty climates?

Dunhouse Buff Sandstone is a high-quality natural stone commonly used for various applications, including both interior and exterior projects. It has good weather resistance and durability, making it suitable for use in many different climates. However, when considering the use of Dunhouse Buff Sandstone in very dusty climates, there are a few factors to consider. Dusty environments, especially those with fine particles, can settle on surfaces and potentially cause abrasion or accelerated weathering over time. Thus, it is important to ensure proper maintenance, including regular cleaning, to minimize the accumulation of dust and dirt on the sandstone surface. Additionally, the choice of surface finish can also impact the sandstones ability to withstand dusty conditions. Honed or smooth finishes may be more prone to dust accumulation compared to textured or rough finishes, which can provide better resistance to dust settling. Ultimately, while Dunhouse Buff Sandstone can be used in very dusty climates, proper care and maintenance should be considered to ensure its longevity and appearance. Consult with professionals or contact the manufacturer for specific recommendations on suitability for your particular climate and project requirements.
