Uses
Tata Yellow is highly apt for colouring of cement and mosaic floors, tiles, dadoes and plastic works colour wash.
Complete and careful mixing of the Tata Yellow flooring colours and cement is imperative for best results. Tata Yellow should be mixed with grey or white cement in the proportion 1:3 or 1:4 (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.
Precaution
Polishing
Buffing and polishing should be undertaken after the floor has been allowed to dry for a week. More time will ensure a better hardening.
