We have a variety of unique colour pigments available for applying to casted patio slabs or garden ornaments. The pigment can be added to any wet pour concrete, mortar renders or paints as well, to display a wide range of colours that are available. Our pigments are high quality, dry, lightfast, odourless, alkali and weather resistant, UV stable, and non-hazardous.
The powdered pigment is added during the mixing process of the material. This product is not designed and should never be applied to the external surface of any material as it will not stick and will run.
Due to individual computer monitors rendering different colours, we cannot guarantee that the pigment image you are buying is the exact colour of the pigment although we can guarantee that it will be very close within the colour spectrum. We cannot be held responsible for any colour issues of our pigments, there are simply too many variables that are out of our control.
The ratio of pigment to mix is relative to the amount of powdered cement in your mix, usually between 2 and 8% (20-80 grams of pigment for every kilogram of powdered cement).
But there is no best answer to the question ‘How much pigment do I need?’ Some of our clients have used pigments in concentrations from 1% up to 10% anything above 10% concentration is starting to waken the concrete so 10 % is the maximum ratio
In most cases, you will need between 1.0kgs and 2.0kgs for every 25kgs bags of powdered cement. The colour of your finished product depends on a number of different factors not related to the pigment itself
– The colour of the sand & aggregate and the type and colour of powdered cement ( the lighter the sand the better the result of the finished product
– White cement will always give you a colour closer to that of the pigment itself, Saying that the use of white cement is better for lighter colours and grey cement for darker colours as don’t need so much to get closer to the colour target
