Bayferrox® color pigments add life to pavers. They can be used to color any kind of stone; from earthy red, brown and black, all the way through to yellow. The lightfastness and weather resistance of the pigments ensure that paving blocks keep their rich color over decades of intensive exposure to the elements. Even if a small chunk should break off, it goes unnoticed because of the integral coloring. However, Bayferrox cannot prevent efflorescence, nor can it cause it. Efflorescence must be seen for what it is: A sign of life from a product made of natural raw materials.
