Mix with water to a trowelling consistency, as a guide approx. 180mls of water per kilo of material. We do not recommend the addition of cement dye/ pigment.
If laying bricks then the bricks should be wetted first to ensure good adhesion of the cement. The joint thickness can be from 3mm upwards. The material will set in a few hours, taking longer in cold weather.
For gap-filling thicknesses above 15mm, use Vitcas Heatproof Screed.
