Bostik Liquid Colour for Cement is a high-performance pigment dispersion designed to bring long-lasting, vibrant colour to all types of cement-based mixes. Whether you are working with concrete, mortar, external render, screed or granolithic flooring, this professional-grade colourant ensures even mixing, consistent tone, and excellent lightfastness. Formulated using premium synthetic iron oxide or carbon-based pigments, each colour in the range complies with EN 12878:2014 standards for use in cement and lime-based building materials. The thin-paste consistency allows the pigment to disperse effortlessly into the gauging water, delivering smooth, uniform colouring throughout the mix. For best results, mix thoroughly before use and carry out a small trial batch to confirm the final colour once dry, as sand, cement and aggregate types influence shade outcomes. Bostik recommends using consistent ingredients and water ratios to maintain colour uniformity across larger projects. Pastel tones can be achieved using white cement, and colour retention can be enhanced with Bostik Integral Waterproofer.
