Black 318 Oxide

Blue Circle Black 318 Oxide is a dry powder used for colouring brick mortars, concretes, tile grouting and numerous other cement based products black.

It is recommended to use oxide at a rate of between 5% and 10% of the cement content. For example if one bag of 20kg cement is used in a mix, then between 1kg and 2kg of oxide is required. Using more than 10% of oxide will not deepen the colour at all.

Blue Circle Black 318 oxide is available in a 1kg, 2kg bucket and a 25kg bag
