Colour Hardener

Permacolour Colour Hardener is made up of a special blend of sand, cement, oxides and additives that have been formulated to produce a product that is easy to apply and helps harden the concrete surface. Coloured concrete produced with Permacolour Colour Hardener is the most cost-effective way to  colour concrete as you are only colouring what is seen, not through the whole depth of the concrete that you don’t see. The colour is stronger and also increases the strength of the concrete surface.
