SILRES® BS 1316 is recommended as a water-repellent impregnating agent and primer for normal and reinforced concrete for bridges, roads and buildings.
Processing
Liberally apply two coats (wet-on-wet) of the impregnating agent uniformly to the concrete. Two coats are needed to ensure that all of the surface is covered. Do not allow puddles to form.
Apply as usual with a low-pressure airless spray, allowing the impregnating agent to flood over the surface. Perhaps use a roller afterwards to distribute the impregnating agent more evenly.
- Allow fresh concrete at least four weeks (preferably six) to set before impregnating it.
- 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. Should it suddenly start to rain, stop treatment and cover the impregnated areas.
Dilution
SILRES® BS 1316 is normally used undiluted.
