Primer | Keim Silan Primer. Guidance for specification option: All bare areas should be flood coated with Keim Silan Primer, brush or low-pressure spray applied (undiluted) and within a period of 2–6 hours, the first coat of Keim Mineral Paints must be applied. Kiem Silan 100. Guidance for specification option: For use on all mineral substrates, particularly suitable for concrete, where carbonation resistance is required. Substrate should be thoroughly flood coated. Keim Silan 100 reacts with the humidity of the concrete and forms a water repellent layer under the influence of the alkalinity. Can be applied as a two coat system wet-on-wet. Can be over painted with Keim Mineral Paints after a waiting period of approximately four hours (but no more than 12 hours). |
Concrete repair | Keim Concretal MKH. Guidance for specification option: For sprinkling into the required amount of water with constant stirring and mixed to a homogenous, lump-free mixture until a readily brushable consistency is obtained. The duration for mixing should be a minimum of five minutes using slow-running stirrers/ mixers. For 20 kg of Keim Concretal-MKH, between 3.6–3.8 L of water is required. Keim Concretal-MKH should be applied onto the prepared bright steel reinforcement, using suitable paintbrushes in two coats. Each coat must be applied all round, covering the entire surface. Care must be taken to ensure that tie wires and edges are carefully coated in order to achieve the necessary application rate Keim Fine Finishing Mortar. Guidance for specification option: A final layer of Keim Fine Finishing Mortar, mixed with clean cold water to a moist earth consistency, should be applied by trowel; this will form a skim layer which will give a level surface to ensure that there is an adequate key. When all surfaces are clean, sound, wind dry, dust free and free from all surface contaminants, decoration using Keim Mineral Paints may proceed. Keim Repair Mortar. Guidance for specification option: After a further minimum period of three hours, Keim Concrete Repair Mortar, mixed with clean cold water to a slurry should be thoroughly brushed around all areas that have been affected to form a good key. Should be mixed with clean cold water to a moist earth consistency and trowelled onto pre-wetted areas to a thickness of between 0.5–10 cm and allowed to dry (localised repairs). |
Finishing coat | Keim Concretal C. Guidance for specification option: Should be thoroughly mixed beforehand using a mechanical mixer, applied undiluted, by brush or roller and worked well into all surfaces. After a minimum period of 12 hours a final coat of Keim Concretal C shall be applied. A wet edge should be maintained at all times during application and contractors should work to a natural break-line. Keim Concretal Lasur. Guidance for specification option: Water repellent, low pigmentation, silicate colour wash which penetrates the surface of concrete to equalize colour variations. Keim Concretal W. Guidance for specification option: For use in conjunction with Keim Fine Finishing Mortar. Keim Concretal W is a mineral matt finish silicate based paint system, the first coat to comprise Keim Concretal W in the chosen colour diluted 30% by weight with Keim Concretal Dilution, a liquid silicate binder. Apply by brush, roller or airless spray and work well into all surfaces. Two coats may be required. |
