Renderoc RG is supplied as a ready to use blend of dry powders which requires only the site addition of clean water to produce a free-fl owing non-shrink repair micro concrete. The material is based on Portland cements, graded aggregates and fi llers, 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, the mixed Renderoc RG may be modifi ed by the addition of 5mm to 12mm clean, graded, saturated surface dry aggregates at site. For exceptionally large repairs, the local Fosroc office shall be consulted.
