Fosroc Renderoc GP is a ready-to-use blend of Portland cements, graded aggregates and chemical additives requiring only the site addition of clean water. Polymer modification gives extremely low permeability to water, carbon dioxide and chlorides, and the cured mortar is impermeable to acid gases and waterborne contaminants. An exceptional shrinkage compensation system provides long-term dimensional stability. The mortar is specifically engineered for vertical repair work and frequently eliminates the need for formwork, it can be applied up to 70mm on vertical surfaces and 60mm on overhead surfaces in a single application. Thicker sections can be achieved by building up in layers or using formwork. Minimum application thickness is 10mm. Deep pockets can sometimes be filled in a single application depending on the configuration and volume of exposed reinforcement. Renderoc GP can also be applied quickly and efficiently by wet spray technique, which offers economic advantages on large areas of repair through faster placement and higher build. The product must not be used in trafficked areas. Typical applications include; Reinstatement of concrete columns, beams, soffits and walls, repair of honeycombing and areas of deteriorated concrete, general purpose structural and non-structural concrete repair and render coat applications Benefits Single component add water only Specifically engineered for vertical and overhead repair Up to 70mm thickness vertical / 60mm overhead, without formwork Long term dimensional stability Chloride free Can be applied by hand or wet spray Extremely low permeability to water, CO2 and chlorides Good to know Compressive strength: 15 MPa at 1 day / 30 MPa at 28 days BS EN 1504-3 Class R3, repair methods 3.1, 3.3, 4.4, 7.1 and 7.2 Not suitable for trafficked areas Yield: approximately 16 litres per 25kg bag Do not apply below +3°C
