Masters Colour Hardener is a dry shake coloured surface hardener, ready to use. It is used for two reasons: colouring and hardening freshly placed concrete. Typically used to provide the base colour for stamped concrete, it is also necessary when installing stencilled concrete.
Masters Colour Hardener is comprised of Portland cement (40%), blended silica quartz aggregates, colour inorganic pigments and other admixtures. This formulation allow to have a special consistency (like a modelling paste) to highlight the smallest details of all stamps models.
In the first place, you have to prepare your construction site into the standards rules for realize a traditional concrete screed. Your subgrade should be carefully prepared, compacted and levelled. Set the forms to the correct elevation and make your levels for draining water.
Have a good concrete mix is very important, use a minimum of 35% of Portland cement per cubic meter and less of 175 liters of water. Remember, more you have water, more you will risk having cracks. Prefer do not use retarding or water reducing admixtures especially when they contain calcium chloride. Place your concrete and use a no-metallic bullfloat for surfacing. After surfacing carefully your fresh concrete, and when all the bleed water has dissipated, hand broadcast your Masters Colour Hardener in two times. About 85% at the first time and when the colour hardener had absorbed the moisture, shake again the rest of 15%. A third shake must be necessary when you are working with light colour.
