Bostik Colours for Cement Brick Red - 1kg - For Concrete, Mortar, Render and Screeds - Available in 5 Intermixable Colours - For Interior and Exterior Use

Excellent product.

I found that the product does turn the brick black but only after a few coats, but the end result is very good, my only one criticism is that when it arrived the lid had become loose and quite a bit of the powder was spilt into the box.

Quality product. Color as described. Dries quickly .

This is a cement colouring powder to add to a dry mix of mortar or concrete, it is strong in colour so only requires a small amount to be added to the dry mix, the down side is until the water is added the exact colour of the mix cannot be judged. Accurate measuring of the amount of powder added needs to be taken down to the gram in weight otherwise different shades of the same colour will be apparent with each mix, extra powder cannot be added once the mix is wet. A tub of this powder will go a long way however care in use needs to be taken due to it's strength of colouring.

Bought to colour cement but not given me what I wanted

Excellent product,also just using common sense to get the right or near as colour mix, and did add a little extra after it was mixed,worked out fine ...

This is really good for colouring cement for repairing bricks without detriment. TB

Perfect cement based colour. It's so easy to use if the instructions are followed. My gable edge tiffins have started to dislodge. I've coloured the replacement mortar to match roof tiles, looks great.
