Cemcraft's NEW Brick Red pigment is designed to produce a medium red colour in concrete, mortar or render.
Cemcraft's unique colour pigments are for use in casting patio slabs, garden ornaments or for colouring any wet pour concrete, mortar or render. Sometimes referred to as 'cement dye' or 'mortar dye', the powdered pigment is added as the material is being mixed.
Pigments are routinely used from .05% up to 10% concentration (NEVER use at more than 10% concentration). We cannot be more specific on concentration as colour is so subjective and the colour of your finished product depends on a number of different factors - not just how much pigment you use. The colour of the sand & aggregate and the type and colour of powdered cement (standard gray, light gray or white) will also affect the colour of the finished product. White cement will always give you a colour closer to that of the pigment itself.
