Concrete stains are undoubtedly a better choice if your priority is decoration. Acid stain penetrates the concrete’s pores and reacts with its constituent parts. Concrete stains can be used to colour concrete on interior or exterior surfaces. When sealed and polished, they produce a high sheen floor that is simpler to use for patios or interior decorative floors. However, paint is a better option if you want to add a layer of protection against damage to the concrete’s surface. Concrete paints also provide an opaque appearance.
