Liberally apply several coats (wet-on-wet) of the impregnating agent uniformly to the concrete. Do not allow puddles to form. Apply with a low-pressure pump, allowing impregnating agent to flood over the surface. For even distribution use a roller afterwards. - Allow fresh concrete at least two weeks - preferably four - to set before impregnating it, to ensure that the cement sets properly. - Remove coarse particles and dust from new<(>,<)> unsoiled surfaces with a brush or compressed air. Use superheated steam to clean weathered surfaces that are heavily soiled with oil, abraded rubber<(>,<)> etc., prior to treatment. - Only impregnate concrete that has a uniformly dry surface with no damp patches. An equilibrium in humidity with the outside air is reached, when a freshly produced surface of fracture is not turning lighter in appearance (due to drying). No darkening of concrete or condensation may occur over night underneath a PE film (500 mm x 500 mm) attached to the concrete at its edges. - Should it suddenly start to rain, stop treatment and cover the impregnated areas. SILRES® BS 1601 should not get into direct contact with bitumen. The resistance of thermal insulating materials against <(><<)>productname> has to be determined.
SILRES® BS 1601 is recommended as a water-repellent impregnating agent and primer for normal and reinforced concrete for bridges, roads and buildings.
