Complete and careful mixing of the Tata Black flooring colours and cement is imperative for best results. Tata Black should be mixed with grey or white cement in the proportion 1:4 or 1:5 (colour of cement), depending upon the desired depth of the colour- [Grey cement is recommended for deep shades and white cement for pastel shades]. Moreover, to eliminate the occurrence of patches and also to produce a smooth and uniform finish, the colorant and cement must be mixed in a dry state before adding water. The mixture has to be applied by trowelling. A 24 hour gap has to be maintained before curing is undertaken for setting.
