The acid stained floor is in fact a truly “custom-made floor” that is designed and built according to the designer’s and customer’s requirements. Acid Stained floors are created using particular acids from metallic salt compounds which penetrate into the concrete and react with the free lime, chemically changing the colour to produce unique and permanent variegated effects. Ideal Work acid stains create variable, diverse or translucent effects that are very similar to the nuances of natural stone or the aged appearance of a weather worn coating. The result is unique for each surface and can not be duplicated with other dyeing materials. Concrete loses its banal appearance and takes on a rich and natural beauty.
