Concrete Colour Hardener

Permacolour Concrete 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.

Permacolour Concrete Colour Hardener is hand broadcast over freshly poured concrete and worked into the surface using a bull float for the first application and trowel after the second coat is applied. When properly applied and troweled into the surface, it forms a coloured concrete surface that is resistant to weathering, wear, and normal abrasion.

For beautiful, long-lasting coloured floors, driveways, paths, and patio's apply Permacolour Concrete Colour Hardener to newly placed concrete. This product is suitable for use with Permacolour Texturing Mats and Permacolour Release Agent for textured concrete and equally as effective for flat trowelled concrete surfaces.

Coloured concrete produced with Permacolour Concrete 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.
