Because of the various surface treatments, such as acid wash, flamed and honed, the blue limestone is one the most popular exterior building materials. It generally depends on the designers’ brilliant ideas, which surface treatment to choose from, to achieve a visual effect or a particular function. The acid wash, for example, can create a friendly rustic look with less corrosion traces and is often applied to flooring in gardens, squares, and places of interest. Why not give it a try!
