Bondit Powdered Cement Colour Dye is a straightforward way to add permanent colour to mortar, concrete, render and cement mixes. Each 1kg tub uses high quality oxide pigments that are light-fast and non-fading, so the colour you mix in stays the colour you get — years down the line. If you have ever pointed a wall with a grey mortar that stands out like a sore thumb against aged stonework, you will understand why cement colour dye earns its place in the van.
The powder is chloride-free, which matters for reinforced concrete work where chloride contamination can cause long-term corrosion issues. It is formulated to incorporate easily into the mix without clumping or separating, and the quantity can be adjusted to dial in different shades from the same tub. A touch more pigment gives you a deeper tone; back it off and you get a softer, more natural finish. Available in Black, Brown, Buff and Red to cover the most common requirements on site.
Where Bondit Cement Colour Dye Fits Into the Job
This is not a specialist product requiring specialist knowledge. You add it to your mix the same way you would any dry admixture, and it works alongside other admixtures without causing compatibility issues. It conforms to EN12878:2005, the European standard for pigments used in concrete and mortar, so it meets the requirements for specification work where conformity needs to be demonstrated.
The cement colour dye works on everything from bricklaying and repointing to floor screeds, cast concrete and external render. Supplied as a dry powder in a 1kg tub, it is easy to measure out on site without mess. For larger decorative concrete pours or render projects, buying in bulk from DTS keeps the unit cost down and ensures colour consistency across batches — something that matters a lot if you are matching existing work.
Pro Tip: Weigh your pigment rather than scooping it by eye — even small variations in the amount added per batch will show as tonal differences once the work dries, especially on large flat render panels.
Powdered cement colour dye is used wherever a specific mortar or concrete colour is needed. Bricklayers use it to match pointing to the brick colour, avoiding that clinical grey mortar look on older or hand-made bricks. Renderers add it to external scratch coats and finish coats to achieve coloured renders without relying solely on painted finishes. Landscapers mix it into concrete edgings, path slabs and decorative pours where a natural stone tone is preferred.
It is also widely used in conservation and restoration work, where matching the colour of existing mortars is essential. Buff and brown tones are particularly common on sandstone and limestone buildings. Black and red pigments see regular use in decorative flooring and exposed aggregate work.

Not suitable for: Not suitable for use as a surface paint or coating — this is a mix-in pigment only. Not recommended for colouring gypsum-based plasters or lime putty mixes without prior testing.
Measure out the pigment by weight rather than volume for consistent results across batches. Add the powder to the dry mix before introducing water, distributing it evenly through the cement and aggregate. Mix thoroughly until the colour is uniform, then add water and continue mixing as normal. The more pigment added, the deeper the tone, though there is a point of diminishing returns beyond around 5% of cement weight.
Keep records of the exact ratio used so you can replicate the colour on subsequent batches. Colour will appear darker when wet and lighten slightly as the mix cures and dries, so do a small test batch first if you are trying to match existing work.
Weigh out the required amount of pigment — typically 1 to 5 percent of the cement weight, adjusted to achieve the target shade.
Add the powdered dye to the dry cement and aggregate before introducing water.
Mix the dry materials thoroughly until the pigment is distributed evenly with no streaks.
Add water and mix to the required consistency, continuing to mix until the colour is uniform throughout.
Carry out a small test patch if matching existing work, and allow it to fully cure and dry before comparing colours.
Keep a written record of the pigment ratio used per batch to ensure consistency across the whole job.
How much powdered cement colour dye should I add to my mix?
As a starting point, use between 1 and 5 percent of the cement weight. A lower percentage gives a lighter, more subtle tone and a higher percentage gives a deeper, more saturated colour. Always do a test batch and allow it to cure fully before committing to a large area, as the dried colour will be lighter than the wet mix.
Will the colour fade over time?
No. The pigments used are light-fast oxide pigments, meaning they do not break down under UV exposure. The colour is permanent and built into the mix itself rather than sitting on the surface, so there is nothing to peel, flake or fade.
Can I use this cement colour dye alongside other admixtures such as plasticisers or waterproofers?
Yes, it is suitable for use in conjunction with other admixtures. The pigment is inert and chloride-free, so it does not interfere with the performance of standard admixtures. If you are using an unusual combination of products on a specification job, a quick compatibility check is always sensible.
Bondit Powdered Cement Colour Dye is manufactured using iron oxide and other inorganic pigments that are chemically stable within alkaline cementitious environments. The chloride-free formulation meets the requirements of EN12878:2005, the European standard governing pigments for colouring concrete and mortar. The pigments are insoluble, non-bleeding and resistant to UV degradation, making them suitable for both interior and exterior applications. UKCA approved for use in the UK market.
