Rapid set and high strength repair mortar.
Newton 203-RM is a single-component, fast-setting, Portland cement-based structural mortar, used primarily for the durable repair of concrete. It is suitable for areas that cannot be taken out of service for long periods, or where the concrete is subjected to heavy wear such as roads, runways, bridges, decks, floors and footpaths.
Polymer-modified, and fibre-reinforced, Newton 203-RM is physically and chemically compatible with the host concrete, quickly exhibiting high adhesive and compressive strength. As a single component, requiring only the addition of water, the resulting mortar is rapid curing with enhanced polymeric properties and reliable strength development which is not significantly affected by low temperature use. The mortar can be used as supplied up to 100 mm deep, or it can be bulked out with sharp sand to form a high-performance screed or for floor or deck repairs up to maximum depth of 300 mm.
Surface preparation is required, as is protection after application - consult manufacturer for details.
