The powder consists of a blend of cements, graded aggregates and chemical additives, and is delivered as a light grey powder.
The liquid part (Nitobond ST), which contains modified acrylic polymers, gives Renderoc ST 05 a creamy, user friendly consistency with extremely good barrier characteristics.
The product exhibits excellent thermal compatibility with concrete and is fully compatible with other Renderoc mortars and Dekguard coatings.
Exposure to rainfall prior to the final set may result in water uptake and severe reduction in the performance of the hardened product. Exposure to mist or high humidity prior to sufficient hardening may result in discolouration of the surfaces.
It is therefore not advisable to use Renderoc ST 05 as final coating, where it requires strict demand for a uniform and decorative surface coat. These white discolouration will decrease with time.
