Perma Colour Chemical Stain is a blend of acids metallic particles and special additives which when applied to concrete, must penetrate the surface to combine chemically with elements in the concrete to form oxides.

The shade of colour obtained will be distinctly different when stain is applied to either old or new concrete. The initial colour of the concrete before the stain application can also effect the finished appearance. An application of Perma Colour Chemical Stain will actually exenterate dark areas of the concrete and cause them to be more of a contrast to the lighter sections.

Perma Colour Chemical Stain may be applied over another colour to create interesting colour blends. The stain comes in 2 and 5 litre containers. Coverage is approximately 10-20 square metres per litre depending on method of application.
