Iron Oxide Cement Colour

Iron oxide powder for colouring cement, mortar, render and concrete. Iron oxides do not dissolve in water, stand up to the alkali in cement, and keep their colour in sunlight and weather.

Add up to 10% of the weight of the cement. Weigh the powder for every mix and keep a note of it, so each batch comes out the same shade.

Sold in 500 g tubs, in six colours. The colour patch in each photo is a guide only.
