Color hardener produces attractive, vibrant concrete that is dense, abrasion-resistant, durable and easy to maintain. Color hardeners have weather resistant and lime proof agents to help protect the color. The stamp pattern is imprinted in the color hardener and therefore the based concrete remains untouched allowing for a stronger product. The color hardener also seals off the pores of the base colored concrete. This allows the sealer to stay on top of the product and means this product does not need to be resealed.
