Thematerial is based on Portland cements, and fillers, and additives which impart controlled expansion characteristics in the plastic state, while minimising water demand. The low water requirement ensures high early strength and long term durability. For larger repairs, Renderoc RG(L) may be modified by the addition of 5mm to 12mm clean, graded saturated surface dry aggregates at site. For exceptionally large repairs, the local Fosroc office should be consulted.
