La Roche Acid Washed Limestone

Safe & Stylish Outdoors

La Roche Limestone from Stoneworld Oxfordshire is an exquisite, medium-beige stone celebrated for its durability and refined aesthetic. This limestone offers remarkable versatility, allowing you to achieve a seamless flow between indoor and outdoor spaces—a popular choice for UK homes and gardens.

Available in tumbled, honed, and brushed finishes, La Roche brings a warm, natural look to interiors, while maintaining strength for outdoor applications.

For outdoor settings, particularly around pools or other wet areas, the traditional smooth finishes may become slippery. To ensure safe and beautiful surfaces, Stoneworld provides an Acid Washed finish, adding a non-slip texture to La Roche Limestone while preserving its unique look.

The Acid Washing Process

The Acid Wash process is a careful treatment using a 98% Hydrochloric Acid (HCL) solution, applied to create a textured, non-slip surface ideal for outdoor use. Here’s how it works:

Application: The HCL is sprayed directly onto the stone’s surface. Initially clear, the solution reacts with the stone, darkening to a coffee-like shade. This temporary colour shift, which may vary from stone to stone, is a natural part of the process.

Colour Evolution: The initial darker shades gradually fade due to exposure to sunlight and water, evening out across the surface in approximately 3-9 months.

Long-Lasting Beauty: Once blended, the Acid Washed finish requires no further maintenance, ensuring La Roche Limestone retains its beautiful, natural look for years to come.

Why Acid Wash?

For outdoor applications, especially around pool areas, using La Roche Limestone without the Acid Washed finish is not advisable. The smoother finishes, while beautiful indoors, can become dangerously slippery when exposed to moisture. Our Acid Wash creates a reliable, textured surface that provides the ideal level of grip for outdoor use, combining safety with the timeless elegance of natural stone.

With La Roche Limestone and our Acid Washed finish, you’ll achieve a safe, stunning, and cohesive look indoors and out. Initial variations in colour after treatment will fade, revealing a natural, blended aesthetic that remains both beautiful and functional for decades.
